If you want some actual explanations, watch Eugene Khutoryansky and PBS Space Time. This channel is just pop-sci for the masses. This guy even failed to consider time in the GR part of the video, completely failing since space and time are inseparable. He was just talking about the geometry of space. There's a 4th dimension, and its because of the time-dimension that gravitational "attraction" even exists. For example, the Moon orbits the Earth not because Earth curves space like a weight on a sheet, but because gravitational time dilation. Time literally runs slower for the parts closer to Earth, and faster for those further from Earth. This causes gravitational attraction.

Gravity:avity: Imagine a sheet called space moving through a 4th dimension where the 4th dimension was called time. The fabric’s direction of travel is from a place we call the past to a place we call the future. The surface of the sheet is what we will call the present. This 4th dimension is not the same as our ordinary experience of time but is related to it. If you put a lead ball on the moving fabric the ball would resist the movement so as to cause the fabric to deform. The ball and the fabric pushing the ball would lag behind the rest of the fabric. According to our definitions, the ball could be said to be in the past. If another ball were put on the fabric it would deform the fabric too. If the two balls were close together they would approach. The balls would seem to be attracted to one another but in reality, they would be both moving toward the same place.

The type of energy spike I would get, my Time perception was flawed. I thought Time would slow down, however, my perception of it sped up. 2 black holes gave me a quarter second energy chirp. I was like, where’s the rest of it. Expecting a big package, got something I could barely record with LIGO. I figured LIGOs equipment not sensitive enough to pick through all the nuances in that energy burst, since everything is being argued as Theoretical until proven. For all you CERN physicists.

Moreover they are clearly not in the lest bit concerned by their pasivity.

Aether answers everything, Standard Model Science Fiction just makes up names for the same things, different energies. Aether has a Dielectric energy hyperboloid that rotates in one direction. It's really 2 vortices, an electron and a positron. Separated by the near infinite capacitance of the Inertial plane/Counterspace. Surrounded by Aether's Dielectric voidence field/Magnetism. That creates nodes from there coaxial circuit, transverse waves, that EM waves/Light propagate on. Light does not have a speed, Light has a rate of induction. Light is instantaneous/entangled, creating these nodes. Light's rate of induction is Magnetism's rate of node creation. The Universe began when Dielectric energy tunneled from the Inertial plane/Counterspace. Dielectric energy created Space to exist in. This is when Time began. Ken Wheeler and Eric Dollard. Dielectric energy is Terminate to Terminate, Inflation. Dielectric energy became it's own field of Dielectric voidence field/Magnetism. Magnetism gives Magnitude to the Universe. The Grand Expand/Big Bang. Dielectric energy and Magnetism transverse waves created the nodes, that EM waves/Light propagate on. Temporal into Spacial. And then some! Ha!!

[@catkeys6911]

Beautifully explained! I had to picture a traveling compression wave in my head, though, because the animation at 15:46 was unable to show that. It just shows a "slinky" stretching and compressing. With a *real* slinky in your hands, though you CAN see this effect if you hold one end steady, and make a quick compression motion with the other - you will see a compression wave travel from that hand towards the steady hand.

[@AmmoDude]

Yes, a slinky will contract on its own, from tension, to it's original compressed state. As all springs will do, they will return to their original state. Once in their original state, they will remain there until a compression or expansion force (mechanical, heating, cooling, etc) is acted upon them, they will not expand or contract on their own. So, in order for this image of gravity to work, there must be an attracting and repelling force on both ends of the wave or in between both ends, these forces oscillating in unison with each other, one pulling and the other pushing at the same time. The closer one end gets to the opposite end, the force pulling is diminished and evolves into a repelling force. A wave, on the other hand, moves away from the energy source until it contacts resistance. The resistance absorbs some of the wave's energy as it changes direction. A wave will eventually loses all it's energy and expire; it is not perpetual unless another force is introduced to perpetuate the motion. Yeah, I still don't get it.........

As far as Solar System in concerned there are many things involve there. 1) The planets are arranged in the form of conic section from top to bottom with two naves of cones maintaining all the norms of circles and ellipses. 2) Probably the Sun is kept at the centre which governs all other planets. There are reactions between the different elements in the Sun with the elemen ts present in other planets. That may be the reason for the different vibrational sounds in planets. Otherwise there is no source for vibrations for such large bodies.3) We can apprehend anorher reason for the activity of the planets ie.

[@tomlakosh1833]

Here’s an amateur TOE based upon a quantum gravity particle. The force carrying particle of the Big Bang also had to combine to form matter as it cooled because there was nothing else to combine into structure. My choice is Planck length photons which are composed of 4 brane and 3 brane strings, (the source of entanglement), interlaced on the surface of a prolate spheroid that has protruding positive and negative poles. These poles are functional worm drive gears that allow the photons to form daisychain into chiral loops that can form straight shafts and one to three aspect ratio tori. These shafts and tori combine to form ambipolar solenoids, (aka gluons), that have counter-rotating shafts, which amplify the ambient electromagnetic fields to produce a much more powerful local field. The gluons can then fuse to form ring shapes that combine to form the charged fields constituting the shells of leptons and baryons. The gluons can condense in galactic EMF via Feshbach resonance to be dispersed as dark matter back upon the galaxy to generate BTFR. The gluons generate gravitational thrust by penetrating the spherical leptons and baryon and accelerating as a superfluid waveform in the subwavelength cavity to generate vectored thrust as exhaust from the South pole of the particle that polar orients toward the dominant gluon flux. The exhaust is vectored by the external quantum fluid formed by gluons on the surface that were at an acute angle or were too slow to penetrate into the spherical particle. This surface fluid also forms a dual membrane slipstream at the equator where the fluid from both hemispheres collide to form something like a disc MHD generator field. That field interacts with the gluon flux to stifle acceleration as space-time viscosity by absorbing the momentum of the flux thus generating an opposing thrust to gravity in the wide field. This slowing of the gluon flux via the viscosity mechanism eventually renders the flux to slow to penetrate the spherical particles and instead enhances the viscosity field to manifest dark energy where the gluon flux crossing megaparsecs is repulsive but the fast local gravity still works. This is why the galaxies in high Z superclusters act like windsocks in the laminar flow of the slow gluons, with all disks in the same plane and with their long axes all parallel to the direction of red shift propagation. Indeed, the Hubble constant is just a measure of the average percentage of gluon slowed to a repulsive velocity over a megaparsec. Just guessing. BTW, black holes are likely solitons surrounded by Fermi slush, (a Fermi solid mixed with quantum fluid generated by friction caused by incoming particles). The exterior skin presents a subwavelength cavity forcing all incoming particle into a waveform that maintains a superfluid state confined by the other waveforms.

The thing that has always bugged me about forces on particles being explained by the exchange of force carriers, is that I have never seen an explanation of how the interacting particles know of each others presence, so that the force carrier can be sent (and where to send it).

[@Erythang808]

This is just my opinion from what I've gleamed. Everything vibrates, everything in this realm. Gravity can't vibrate unless it is a molecule. Probably, a quantum one, and is carried along by tachyons, neutrinos, protons, etc. I believe that as mass, which is compressed light, carries gravity in every particle on a subatomic quantum level (we aren't able to observe at this present time) the gravity particle is already present and working in conjunction with the electron particles. As the electromagnetic waves from two masses come into contact with eachother, the gravity and electron particles form convergence waves. In this union of forces, the information is traded as particles collide. I hope I explain the process enough for you to visualize the function. If you have a question ask away! Blessing!

8:52 When the moon orbits around the earth it is not moving in a straight line. Straight lines are geodesics, and these can be seen always by the trajectory of light. So the moon's orbit follows a curved path that is added to the cuvature of spacetime at that spot. (You can check by throwing a light ray from the moon in the direction parallel to earth's surface: it follows a much, much less curved line than the trajectory of the moon itself). In fact the curvature of spacetime due to earth at the moon's location is extremely small, hardly measurable, and in fact nobody has yet measured it. The curved trajectory of the moon is overwhemly due to the force of gravity caused by the mass of the earth, in turn due to deformation of SPCT that is related to curvature, but it is not curvature itself. Curvature if perfectly depicted by the trajectory of light, clearly diff from that of massive objects. They are different components in the stress-energy tensor.

Superposition is just a way of describing the chaotic yet predictable behaviour at the quantum scales. "Measurement" just describe interaction with other particles, when this happens, a superposition collapse (decoherence). Particles in superposition decohere whenever it interact with other particles.

A Schwarzschild BH event horizon has a Schwarzschild radius of r=2GM/c^2, but BH radial coordinates are not physical distances and a BH does not have a unique radius of any kind (it's observer dependent). 3. Laplace's D.O.has an escape velocity, a BH does not. Light and objects can be launched into space from below its surface. The escape velocity equal to light simply means that objects slower than this come back down and light is emitted into space but is redshifted to infinity at infinity. The BH interior spacetime is a causally disconnect region of spacetime, meaning, there are no causal curves that can extend into the exterior spacetime. 4. A D.O. is a dense ball of matter, a black hole is a vacuum spacetime (T_{ab}=0} and so is just empty space. 5. A BH has a singularity, a D.O.does not. 6. The interiors of each are basically opposites, e.g. the tidal forces in a D.O. go to zero at the center, a BH has no meaningful center, but the tidal force go to infinity as the radial coordinate decreases, etc. Then there is the absence of relativistic effects for a D.O. and entire conceptual frameworks of what gravity is, is completely different.

Carroll is referring to Laplace's theory of gravity where gravity is a fluid flowing into every massive object and in Laplace's own words "we must suppose that the gravitating fluid has a velocity, in Laplace's own words "we suppose that the gravitating fluid must have a velocity of least hundreds of millions of times greater than light." Anyway, there is no resemblance to GR even if Laplace's idea bears a vague resemblance to Gullstrand-Painleve coordinates.

I thought comes to mind that the initial annihilation of the matter and antimatter that sprung from the quantum firmament in the first few seconds of the universe resulted in nearly 100% entropy. That very small amounts of matter and antimatter was left over. However collapsing space-time versus expanding space-time must have also had its annihilation. That what was left over was collapsing space-time in a large degree being dominant over expanding space-time. A space-time that allows for the expansion of space pretty huge volumes of empty space and that matter is generally pressured into confines or filaments of collapsing space time. If they could run a model of the universe in reverse taking out the filaments and reversing time to win the expanding space-time was at zero.

I'm curious if instead of dark matter, could it be extra layers to gravity? So we could just improve off of the gravity we already know that works to an extent already? Like there could be the layer we know, then a large scale layer that's on the scale of entire galaxies and nebula's and other complex and diverse grand massive objects that have all sorts of behaviors interacting with in each other that I'm sure needs to be factored in to get this layer of grand scale gravity correctly. Then there could be sub atomic gravity or micro gravity or atomic gravity layer. That can essentially be the strong force and the weak force but it's just a different version of gravity on the smallest scale. So right now I'm just theorizing 3 layers of gravity, as an improved concept of the nature of gravity withing the natural world. The smaller layer, the normal layer we have understood very well that relates to our solar system type scale. Then there is the 3rd layer, the massive layer. Dealing with things that are light years across, vast temperature differences, density's, velocity's and diversity. Intense pressures, electro static charges, electromagnetism, plasma clouds, black holes, pulsar, quasars, neutron star's, super Nova explosions, gas clouds, solar winds, radiation, tons of interwoven orbital interactions and angular momentum velocities, multiple galaxies interacting upon other galaxies. Just so many things that probably all have to be accounted for when we are dealing with scales with such vast massive intracity, and scales as vast layers of complexity that the 3rd layer of gravity hypothetically could be covering? This is just a gut feeling, and I'm just doing a thought experiment with and I'd love it if someone else wants to improve onto it. I'm all for that.

Why would gravitational waves travel at the same speed as the speed of light? The speed of light is determined by the permittivity and permeability of free space - these are basically properties that determine how fast electric and magnetic fields can be created in a material (in this case free space). What would this have to do with gravity? The presenters say that gravitational waves are basically the compression of space-time itself, while light is basically a moving electrical field generating a moving magnetic field generating a moving electrical field. What do they have to do with each other that they would propagate at the same speed?

[@MrMightyMouse]

The speed of light is actually more accurately described as the speed of causality, or how fast time space can interact. That's why gravity travels at the speed of light.

[@MrMleewilson]

@@MrMightyMouse With all due respect, that has nothing to do with anything. The "speed" of causality is just the fastest speed that an event can occur (passing of information between two points), and that will be the same as the fastest thing in the universe. The fastest thing just happens to be the speed of light. Why gravitational waves have to travel at the speed of light is not explained.

[@albert6157]

In general and special relativity as well as quantum field theory, particles without rest mass travels at the speed of light. Electromagnetic waves and gravitational waves dont have mass, they do not couple with higgs field. Hence travel at the speed of light. Permittivity and permeability of space are just constants measured and used in equations to describe electromagnetism (both its fields and particles) and its behaviour

[@MrMleewilson]

@@albert6157 But the speed of light in a medium is determined by the permittivity and permeability of the medium. If those numbers were different, then the speed of light will be different. For example, the speed of light is different in water, air, or any other medium than free space because these materials have different permittivity and permeability. Would that mean gravitational waves travel at the same speed as the speed of light through that material? If the speed of light varies depending on the material it passes through, what makes it so special that everything else with zero rest mass travels at that speed? And why would space-time change itself so that speed appears constant to all observers in all frames of reference?

[@albert6157]

@@MrMleewilson very good question my guy, there are many mysteries we still do not know. Such as properties of gravitational waves (they are only confirmed recently and they are rare to measure and test.) So we cant say for certain what their properties are. (But as far as we know, we measure it to be the same as the speed of light. Via neutron star collision detection) Like all waves, it all depends on wavelength, energy, and frequency. (and the medium) Photons (electromagnetic waves) with varying wavelengths gets reflected, refracted and interacts matter differently. Like light reflect, absorbs and refract in transparent materials but radiowaves pass right throught them. But the only reason waves reflects or refracts is because the wavelength is small enough (with high enough energy) to interact with particles (electrons or atoms). But light doesnt slow down in any medium, they just bounce around (refracted) by individual particles and losing energy along the way, which makes them have a slower apparent speed. But in the quantum scale they still travel at the speed of light from particle to particle (as it bounces around). We dont know why the speed of light is what it is. But all we know is all massless particles move at this speed. (The permitivity and permeability are just constants to aid calculations) The point is, the speed of "light", is not exclusive to light, it applies to any particle or wave that are massless (we only call it speed of light because its the first particle discovered to travel at that speed). The real name for the speed is "speed of causality".

Einstein may have chosen to model gravity as curvature of spacetime because Riemannian geometry was the only known math that he could use. Einstein's cult of relativity is alive and well. Even many professional physicists don't seem to know that there are viable alternatives. And theories involving only flat spacetime may be easier to unify with quantum mechanics (QFT).

[@kiabtoomlauj6249]

Why is Einstein thought on "gravity" --- in particular, his GR theory --- being a function of the curvature of space-time being a cult thing? Saying "there are alternatives" to something (proven to extremely high degrees of certitude) doesn't say any thing. String Theory, Loop Quantum Gravity, etc. are just FANCIFUL ideas right now. What Einstein said isn't what Aristotle and other ancient babblers said: things just want to go to or to return to their natural given state, or final resting place... or that the "four elements" of what reality's made of are earth, fire, water, cow dung, etc. Einstein, instead, gets very specific: IF what I am saying is true, then you MUST be able to find X, Y, and Z, etc. E.g., light bending around massive concentration of matter... Mercury's "strange behavior" .. in terms of its position at any given time... can be explained by THIS very specific calculation.... clock/time "ticking" away at differential speeds at different environments, such as positions on the surface of large bodies like the earth, the sun, etc. versus positions hundreds to billions of miles away from such highly distorted space-time areas.... the distortion of the fabric of space-time itself, when massive energy/ gravitational vibration manifests itself through it, due to the collision of very dense objects like neutron stars and black holes, etc.... the phenomenon of red-shifting in light due to the expansion of the universe... Again, just because we can't explain "everything in the universe" right now doesn't mean Einstein's GR about "gravity" being a manifestation of the distortion of space-time is a "cult" thing like the BS followed by people displaying Z, Q, V, etc. on signs and cars and windows...

[@Raging.Geekazoid]

@@kiabtoomlauj6249 GR is a cult because people believe in it without proof. GR and gauge theory gravity are both based on the Einstein-Hilbert action, so they're essentially indistinguishable at low field strengths. But there's no curvature in GTG, only a gauge-invariant "index of refraction". So curvature hasn't been proved, and yet the physics community treats it as an established fact. By "alternatives" I mean EXACT alternatives, such as GTG, which only differs measurably from GR at high field strengths, where we don't currently have any experimental data. Or Lorentz's theory of the vacuum ("ether"), which is exactly equivalent to special relativity. Physicists reject it, despite the fact that SR (in its most extreme interpretations) violates fundamental scientific principles like realism and causality.

Einstein and Newton neglected to address the action causing gravity in matter. That's why their equations are unable to describe the motion of massive objects like galaxies and stars. That is why the equations are only able to accurately describe the motion of small objects like planets and moons. If they had added the action causing gravity inside of all large matter, they would have predicted the motion they've so wrongly pinned on dark matter and dark energy. One action when added to their equations explains everything. I wrote and published a series of 6 books on Gravity, Energy and the motion or Kinematics occurring to matter. In the last book of the series I included all the equations that fixed general relativity so that it is able to accurately describe and predict the motion of all large matter in the universe, and not just a small percentage like it currently is able to do. The Book series is called SECRET UNIVERSE by Ron Kemp.

As I was watching this, a singular thought began to pulsate in my mind: Quantum mechanics works. Relativity works. These are probably the two best and most successful theories in all of physics, yet (if theories could have emotions and personhood🤣😅) they seem to 'dislike' each other to the point of breaking down when extended to each others' domain of influence. Specifically, above Planck length, Quantum mechanics breaks. Below Planck length, it's relativity that coughs up a hairball. No matter how hard we try, we just cannot 'shoehorn' one into the other, either mathematically or existentially. This discontinuity has certaiy wrecked a lot of physicists' sleep cycle. The thought that I had regarding this is probably going to sound silly, but I don't think it _is_ silly. _Human science cannot unify quantum mechanics and relativity, but the universe does it flawlessly. Until science (meaning scientISTS😱🤣) figures out how to look at this problem from the POV of the universe, we probably won't be able to gain much traction on it._ I have noticed that the infamous Planck length is the one thing that the 'quantumly' small and the 'Relatively' large share in common. It's almost like some sort of mathematical event horizon that serves as a barrier to the Microcosm communicating with the Macrocosm, except once again, the universe has no problem at all, it's just us human across-structure computational meat sacks who can't do so. Aaaannnnd, that leads me to the question that is the point if all this. _Is it possible that there exists some process or function or interaction, occurring at that Planck level, which serves as a sort of 'transitioner' which ties the two disparate levels of reality, Quantum & Relativistic, together?_ We're missing something, probably something elegantly simple that slithers around in between the equations describing relativistic phenomena and those describing the quantum world. There has to be _something_ , because if the universe had the same problem that we have in unifying the two, we likely wouldn't be here, nor would the universe in this form. Is this even possible? If it is, _then what is that process/function?_ *Things that make us go, "so how many successive nights of lost sleep does it take to fry our neurotransmitter renewal contract & thereby render us incapable of such ponderings?"_ * 👽🤣👀

There are certainly things that relativity does not deal with too well, like the galactic rotation issue, for example. For me, though, the glaring issue is that breakdown at Planck length which sends our theoretical framework for the micro and the macro right into the weeds. I have begun to wonder, if we could solve that problem as the universe itself does, we'd have a tie between the two, which might make all manner of things more clear.

@@skyhorseprice6591 General relativity is far from being complete. Einstein tried for years to complete his equations and died before he could finish them.

Ask any physicist or astrophysicist what's missing from general relativity and they will be clueless. They don't know what's missing or how to complete his equations. If they knew what was missing and were able to fix his equations then dark matter and dark energy would disappear. the reason why they show up as possibilities is because Einstein's equations come up short. I believe general relativity and QM will never be able to merge. I don't believe gravity exists at the quantum scale because it is a reaction, not an action. The same reason why gravity is weaker than electromagnetism or the strong nuclear force because it is a reaction to the other 2 forces, not an action or force.

Plank length is a unit of distance. Light speed is a unit of distance over time. Both are said to be universal constraints. Those two constraints are related by time. It seems possible that until and unless time can be quantified in terms of energy/mass, then the relationship between quantum and relativity observations at the micro and macro levels cannot be discerned.

[@skyhorseprice6591]

@@gmarie701 I have an idea about this. If we look at particles *and* waves as distortions or twists in spacetime itself, we can actually visualize how space, time, mass, and gravitation are related. We know that gravity has a direct effect upon spacetime because of the atomic clock experiment; place one such clock at sea level & another in earth orbit. Calibrate both clocks to be synchronous to the highest degree possible. Observe the time record of each. Over that time record, the clock at sea level starts to fall behind the one in orbit because of spacetime dilation in a gravity well. Spacetime is literally stretched out the further/deeper we go into any gravity well. Why is this? Well, it's because mass bends spacetime. Why does mass bend spacetime? Because particles and waves are all the same thing- distortions or twists in spacetime. Imagine a large, perfectly flat and smooth tablecloth just floating before you. Now, put a bunch of little twists into the cloth. What would you see? You'd see the cloth being stretched into a curved shape that (roughly. This is an analogy, after all) that looks very much like the well known diagram of an unspecified ball of mass sinking into the middle of an increasingly distorted grid. The thing is, this distortion also affects *time,* which is never made clear. So the primary thing this does is, it answers the question, "why does mass affect spacetime and cause it to curve?" That answer is, "mass does not 'affect spacetime', *matter (mass) is COMPOSED OF SPACETIME THAT IS DISTORTED.* " What this does is reveal a universe that is energy based; matter arises from pure energy (spacetime), not the other way round. If this is so, we would then have a key to the long sought TOE.

[@Motor7710]

Interestingly I understood everything they said of what gravity does but they still didn't explain what gravity is. 🤔 So I'm going to stick with my childish explanation which is, there's an ocean of energy in the universe you can call it the ether or dark energy. Doesn't matter, it's the same thing. What this energy does is basically feed all the particles of the universe. All the atoms are basically sucking energy from the universe. This energy is like a waterfall which creates a denser waterfall as it gets closer to the object it's feeding, thus giving you a slope that increases in density. I guess they would call that bending time and space. Anyways... till somebody explains better I'm sticking with my version. But it will say it was a good video,👍 just needs a little bit more info. So What is Gravity? Gravity is the state of compression of energy as it's moving to whatever object. In other words, it's the ether or dark energy or whatever you want to call it. 😊

GRAVITY EXPLAINED The universe is made of minute cells once contained in a universal shell that was broken or rotated by an external force. this produced expansion creating a true void that must not exist, leaving the cells to expand or split,I believe the destruction or splitting of cells is where all matter originates, therefore matter must be the end state of all our universe until the universal matter will disperse or be contained by an outer external force or medium. The cells must penetrate matter to a degree becoming harder the denser the matter until it is so dense it is impossible thus the push back is multiplied infinitely causing corresponding gravity push. As far as so-called gravity it is plain to see that there is no attraction only an external push forcing matter together . Imagine an oil filled rubber ball each molecule of oil must have the same force upon it. Then introduce a foreign particle of the same size and density then each molecule will have slightly higher pressure upon it nothing will coalesce then add a larger or denser body with larger or harder surface to be pushed upon by the other molecules all the molecules will feel a small amount more push but the nearer the large body cells will get pushed harder. [this energy really comes from the constant push from the ball membrane or that exists outside it] then introduce a smaller dense body in the vicinity of the harder pushed cells. if the number of hard pushed cells behind this body is higher than the ones between it and the large body then gravity is achieved. Without resistance to these cells energy would not be forced to navigate a wave pattern, the cells would not become excited and light as we know it would not exist . Energy waves passing through harder pushed cell formations will deviate around the reason they are pushed. Hard pushed cells may be deformed from a sphere into an ovoid making it harder to rotate, also making energy travel differently The universe itself may be such an ovoid thus the reason for expansion. Magnets must rearrange the cells making the rearranging object harder or easier to navigate between depending the manufactured configuration. As far as Quantum physics goes we do not have any real data so mathematical physics is applied and comes up with sometimes fanciful answers to fit a paradox. Understanding a data lacking subject has always failed, people already in this field would do best just striving for accurate observation as some early astronomers did. An understanding will develop with detection instruments and supercomputing enhancements . seeing it first hand. some bright spark will discover the bleeding obvious and mathematise it. We must determine the size and density of each cell by measuring each light wave in relation to one another ,and the number of cells between each crest and finding the correlation that would fit all known energy waves if this can be achieved, the next step must be to create corresponding energy waves before a moving object creating an air in sand effect thus help said object closer to the preceding wave speed Initial measurements should be simple two dimensional with known wave patterns overlaid on the same plane and begin with spherical solid cells filling the voids between the crests of all waves. First, hoping all the energy waves respect the integrity of each cell, if not some types of energy waves may penetrate part of the cell, as do they penetrate some matter. black holes are remnant void bubbles still trying to eliminate the space where cells are absent,destroying surrounding cells and creating matter and drawing existing matter to fill the void .billions may have succeeded leaving small super dense spheres but most can't keep up with the constant universe expansion and will take all their surrounding galaxy and more. No matter how beautiful and pleasant maths is , since the mid 60's, it has blinded physicists before then a physical notion was envisaged then came out the ruler to see if it would stack up. These are some answers to how things unfolded but surely the harder question is why. Why has life evolved to a stage that we can pose these questions? Surely non existence would be the easier option ,without struggle without knowing about your inevitable destruction personally and universally this question is the real puzzle. This is why the emergence of conscience coincided with a genetic predisposition towards a god culture everywhere on earth ,a genetic valium so to speak. which must be ameliorated not railed against by atheist dissenters ,as it just a part of our bodies . The answer can only be chemistry ,all life is simply a chemical reaction , the same as the stars react with each other ,no matter how complicated its components become it must rely on the basic building blocks to exist ,my thoughts while writing this are governed by a chemical reaction and the lightning created by reaction. Therefore if matter has no will and the meeting of different types of matter will react differently then the meaning of life has the same weight as mixing paint ,life and death is eventually inevitable wherever matter coalesces .

The bigger question for me is why the planets don’t get pulled into the sun. What makes a planet find its happy spot in orbit. Must be something to do with the electric field put out. Perhaps that’s what orientates the planters from spinning uncontrollably. I don’t think that thinking of space as a fabric is gonna get us far fast. It’s hard for me to even have a thought experiment where your in a place where there is no ⬆️. I’m just thinking out loud here and am probably way wrong.

We live in at least four dimensions, never forget TIME. The one humanity can't travel within. Cats of course Wrinkle time, LOL

[@quantumtacos]

As a physically 3-dimensional being I so agree with this. But have you ever tried drawing 3-dimensional space on a 2-dimensional LCD monitor? And then tried drawing a representation of a warping of spacetime as an additional dimension on top of that? I've seen an attempt at it and it just looks, well... different but not any better honestly. The problem you're having with understanding those drawings that seem to have a concept of up/down is simply because they've actually done that on purpose. They've deleted one of the 3 spatial dimensions and replaced it with your intuition of "things always fall down" so that they can depict as many spatial dimensions as possible (2) in the same drawing as the gravitational warping dimension (the up/down, which is the whole point of the drawing) and do it in a way that we can intuitively interpret. You're meant to interpret the "down" direction as "this is a trampoline with people standing here and here and notice how a ball therefore rolls in this left/right direction, just like gravity would do in real life if we could draw the full 3 dimensions with a 4th dimension of gravity warp". You're meant to imagine that we are in fact 2 dimensional beings living on a 2 dimensional universe that exists on the plane/surface of a god-like 3 dimensional trampoline and that the 3rd dimension that you see in the imagery is actually representing the gravitational curvature of spacetime because nobody has ever figured out how to draw ourselves as proper 3 dimensional beings being warped into a 4th dimension. It's confusing and it's bad but you can search youtube for videos on "flatland" and related to help fix the badness because you're right that it just doesn't make sense as presented if you're not already indoctrinated into the idea of deleting one or more spatial dimensions to fit them on a 2d/3d picture. Just wait until you get into "spacetime diagrams" where we delete all but one spatial dimension. Actually it turns out that in most of physics we only need to talk about one spatial dimension to demonstrate most concepts. Thank goodness for that because I still can't wrap my 3d brain around what a 4d tesseract actually looks like and I think anyone who can is necessarily a dimensional savant. As a side note, or perhaps the preceding was the side note and this was all you meant to ask: the reason planets don't fall into the Sun is the same reason that if you throw a baseball sideways it won't fall back to Earth. I mean you have to throw it a lot faster than 100 MPH, like, a LOT faster. Ignoring atmospheric drag, if you throw a ball over your neighbor's house at around 6 kilometers per second it will go so far that because the Earth isn't flat it will keep going around the globe and won't land until somewhere in China. If you throw it at EXACTLY (err, approximately) 8 kilometers per second (again, ignoring atmospheric drag) it will keep going around the globe in a perfect circle and smack you EXACTLY in the back of the head. Please don't do that; at that speed even a small baseball would obliterate the top half of your body due to kinetic energy. And if you throw it at some 12 kilometers per second, even if you're aiming only a hair over your neighbor's roof, it will leave Earth's gravity well and never return. It just so happens, after billions of years of planetary evolution, that Earth is traveling around the Sun at around 30 kilometers per second, which is right at the "smack you in the back of the head" perfect circle speed which is why Earth just keeps going round and round the Sun in a nearly perfect circle, never stopping because there's no atmospheric drag to slow us down. The thing that made Earth find our happy "back of the head" orbit is that all the other proto-planets either collided with proto-Earth or proto-Mars etc. or were ejected out at high velocities to never return to our solar system. The only planetary orbits that remain after 4 billion years of this billiard game are the orbits that are circular enough to not crash in to other planets. Or to say the same thing in another way: planets DO get pulled toward the Sun. Earth is pulled toward the Sun by an amount that exactly balances our 30 kilometer per second orbital speed, and so we keep going exactly in a circular orbit. If the Sun suddenly stopped pulling, we'd fly off never to return. And if Earth suddenly stopped our 30 kilometer per second orbital speed, we'd fall directly down into the Sun like an apple falls from a tree.

GRAVITY: (copy and paste from my files): Here is the test for the 'gravity' portion of my TOE idea. I do not have the necessary resources to do the test but maybe you or someone else reading this does, will do the test, then tell the world what is found out either way. a. Imagine a 12 hour clock. b. Put a magnetic field across from the 3 to 9 o'clock positions. c. Put an electric field across from the 6 to 12 o'clock positions. (The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.) d. Direct a high powered laser through the center of the clock at 90 degrees to the em fields. e. Do this with the em fields on and off. (The em fields could be varied in size, strength, density and depth. The intent would be to energy frequency match the laser and em fields for optimal results, cancelling out the em modalities of the laser, thereby leaving behind the gravity modality.) f. Look for any gravitational / anti-gravitational effects. (Including the utilization of ferro cells so as to be able to actually see the energy field movements.) (And note: if done right, it's possible a mini gravitational black hole might form. Be ready for it. In addition, it's possible a neutrino might be formed before the black hole stage, the neutrino being a substance with a very high gravitational modality with very low 'em' modalities.) (An alternative to the above would be to direct 3 high powered lasers, or a single high powered laser split into 3 beams, each adjustable to achieve the above set up, all focused upon a single point in space.) 'If' effects are noted, 'then' further research could be done. 'If' effects are not noted, 'then' my latest TOE idea is wrong. But still, we would know what 'gravity' was not, which is still something in the scientific world. Science still wins either way and moves forward. * And note: Whether my gravity test or another's, a gravitational black hole would have to be formed to prove the concept as being really true. A gravitational black hole that 'if' self fed itself, could literally wipe out this Earth and all on it, possibly this solar system, possibly put a black hole in this section of our galaxy, and potentially even causing a ripple effect in this galaxy and surrounding universe. But hey, if it does, no worries. Nobody would be left to prosecute those who did so. (Possibly famous last words: "Hey, it worked. Ooooppppssss.................) But as NASA has already proven that low gravity conditions over a prolonged period of time is harmful to the human species, and large rotating space ships won't really work for space bases on planets and moons, those space bases probably being needed somewhere along the way out of this solar system and galaxy, we need to figure out what gravity truly is and see if we can generate artificial gravity so as to have smaller space ships and proper gravity conditions for space bases on planets and moons. Otherwise, at least all human life will most probably die and go extinct one day. Currently, no exceptions. ** Added note: Just trying to save at least 1 single species from this Earth to exist beyond this Earth so that life itself from this Earth has continued meaning and purpose to. Gives me something to do while I exist, otherwise, what is it all and everything for? Even if my TOE idea were correct, but if it did not help species survive beyond this Earth, what good would it ultimately be? So, are you feeling lucky? Doing nothing and at least the entire human species eventually dies and goes extinct with a high degree of certainty. Doing a gravity test, (mine and/or another's), and there is at least a slim chance of literally wiping out this entire Earth and all on it, and possibly more. Do you and other's truly want me to prove my TOE idea as being really true?

[@charlesbrightman4237]

Revised TOE: 3/25/2017a. My Current TOE: THE SETUP: 1. Modern science currently recognizes four forces of nature: The strong nuclear force, the weak nuclear force, gravity, and electromagnetism. 2. In school we are taught that with magnetism, opposite polarities attract and like polarities repel. But inside the arc of a large horseshoe magnet it's the other way around, like polarities attract and opposite polarities repel. (I have proved this to myself with magnets and anybody with a large horseshoe magnet and two smaller bar magnets can easily prove this to yourself too. It occurs at the outer end of the inner arc of the horseshoe magnet.). 3. Charged particles have an associated magnetic field with them. 4. Protons and electrons are charged particles and have their associated magnetic fields with them. 5. Photons also have both an electric and a magnetic component to them. FOUR FORCES OF NATURE DOWN INTO TWO: 6. When an electron is in close proximity to the nucleus, it would basically generate a 360 degree spherical magnetic field. 7. Like charged protons would stick together inside of this magnetic field, while simultaneously repelling opposite charged electrons inside this magnetic field, while simultaneously attracting the opposite charged electrons across the inner portion of the electron's moving magnetic field. 8. There are probably no such thing as "gluons" in actual reality. 9. The strong nuclear force and the weak nuclear force are probably derivatives of the electro-magnetic field interactions between electrons and protons. 10. The nucleus is probably an electro-magnetic field boundary. 11. Quarks also supposedly have a charge to them and then would also most likely have electro-magnetic fields associated with them, possibly a different arrangement for each of the six different type of quarks. 12. The interactions between the quarks EM forces are how and why protons and neutrons formulate as well as how and why protons and neutrons stay inside of the nucleus and do not just pass through as neutrinos do. THE GEM FORCE INTERACTIONS AND QUANTA: 13. Personally, I currently believe that the directional force in photons is "gravity". It's the force that makes the sine wave of EM energy go from a wide (maximum extension) to a point (minimum extension) of a moving photon and acts 90 degrees to the EM forces which act 90 degrees to each other. When the EM gets to maximum extension, "gravity" flips and EM goes to minimum, then "gravity" flips and goes back to maximum, etc, etc. A stationary photon would pulse from it's maximum extension to a point possibly even too small to detect, then back to maximum, etc, etc. 14. I also believe that a pulsating, swirling singularity (which is basically a pulsating, swirling 'gem' photon) is the energy unit in this universe. 15. When these pulsating, swirling energy units interact with other energy units, they tangle together and can interlock at times. Various shapes (strings, spheres, whatever) might be formed, which then create sub-atomic material, atoms, molecules, and everything in existence in this universe. 16. When the energy units unite and interlock together they would tend to stabilize and vibrate. 17. I believe there is probably a Photonic Theory Of The Atomic Structure. 18. Everything is basically "light" (photons) in a universe entirely filled with "light" (photons). THE MAGNETIC FORCE SPECIFICALLY: 19. When the electron with it's associated magnetic field goes around the proton with it's associated magnetic field, internal and external energy oscillations are set up. 20. When more than one atom is involved, and these energy frequencies align, they add together, specifically the magnetic field frequency. 21. I currently believe that this is where a line of flux originates from, aligned magnetic field frequencies. NOTES: 22. The Earth can be looked at as being a massive singular interacting photon with it's magnetic field, electrical surface field, and gravity, all three photonic forces all being 90 degrees from each other. 23. The flat spiral galaxy can be looked at as being a massive singular interacting photon with it's magnetic fields on each side of the plane of matter, the electrical field along the plane of matter, and gravity being directed towards the galactic center's black hole where the gravitational forces would meet, all three photonic forces all being 90 degrees from each other. 24. As below in the singularity, as above in the galaxy and probably universe as well. 25. I believe there are only two forces of nature, Gravity and EM, (GEM). Due to the stability of the GEM with the energy unit, this is also why the forces of nature haven't evolved by now. Of which with the current theory of understanding, how come the forces of nature haven't evolved by now since the original conditions acting upon the singularity aren't acting upon them like they originally were, billions of years have supposedly elapsed, in a universe that continues to expand and cool, with energy that could not be created nor destroyed would be getting less and less dense? My theory would seem to make more sense if in fact it is really true. I really wonder if it is in fact really true. 26. And the universe would be expanding due to these pulsating and interacting energy units and would also allow galaxies to collide, of which, how could galaxies ever collide if they are all speeding away from each other like is currently taught? DISCLAIMER: 27. As I as well as all of humanity truly do not know what we do not know, the above certainly could be wrong. It would have to be proved or disproved to know for more certainty.

[@charlesbrightman4237]

'IF' my latest TOE idea is really true, (and I fully acknowledge the 'if' at this time), that the pulsating, swirling 'gem' photon is the energy unit of this universe that makes up everything in existence in this universe, and what is called 'gravity' is a part of what is currently recognized as the 'em' photon, the 'gravity' modality acting 90 degrees from the 'em' modalities, which act 90 degrees to each other, then the oscillation of these 3 interacting modalities of the energy unit would be as follows: Gravity: Maximum in one direction, Neutral, Maximum in the other direction; Electrical: Maximum in one direction, Neutral, Maximum in the other direction; Magnetic: Maximum in one direction, Neutral, Maximum in the other direction. Then: 1 singular energy unit, with 3 different modalities, with 6 maximum most reactive positions, with 9 total basic reactive positions (neutrals included). Hence 1, 3, 6, 9 being very prominent numbers in this universe and why mathematics even works in this universe. (And possibly '0', zero, as possibly neutrals are against other neutrals, even if only briefly, for no flow of energy, hence the number system that we currently have. This would also be the maximum potential energy point or as some might call it, the 'zero point energy point'.). And also how possibly mathematical constants exist in this universe as well. * Note also: Nobody as of yet has been able to show me how numbers and mathematical constants can exist and do what they do in this universe from the Standard Model of Particle Physics (SMPP). While the SMPP has it's place, I believe we need to move beyond the SMPP to get closer to real reality.

[@charlesbrightman4237]

'quantumtacos': If you see this post, I see you posted a comment, that appeared to be an intelligent comment and request, but then I cannot find your comment here. Did you delete it? But anyway, 'yes', it is currently my belief that if one were to cancel out the 'em' of the laser, 'gravity' would be left, most probably in the form of a mini gravitational black hole. Based upon my current studies and understandings, I believe that what is called 'gravity' is a part of what is currently recognized as 'em' alone, gravity acting 90 degrees to the 'em' modalities, which act 90 degrees to each other, and is the reason why 'em' has a sine wave pattern. The gravity test above will speak for itself. It will either be true, partly true, or not true at all. It will either show what gravity is, might be, or is not. In any event science would 'win' and move forward.

[@peterclark6290]

We already suspect that there are attractive and repellent forces that hold atoms in balance. We also suspect that atomic materials are made up of perpetual energy even smaller than electrons, protons... We know that some materials have an attractive force similar to Gravity called Magnetism. Putting together the experiment to prove they are one and the same: i.e., excess attractive waves unused by the atomic structure are able to reach beyond the 'mass' will earn the first person to do it a Nobel. Guaranteed. Furthermore demonstrating that the Universe (indeed the Cosmos) is made possible by the binary logic of those energies by compounding them is the key to Science, and by extraction Physics. By looking for simplicity first. e.g., the larger the mass the greater the attractive energy tells you... that energies are under-used so they can do other things...? You don't need Einstein's wild guesswork anymore, be free. BTW we will never be able to prove any of it, we came along (17 billion years) too late to see 'inside' and collect evidence but common sense says it ain't what you got, it's what you do with it.

Any construction requires rock solid basic elements and the mere fact that we are here in a functioning Universe indicates a permanency of basic form. As I understand it there is only Energy and Space. The fundamental energy 'packets' can compound into atoms and from those to acids, alkalines, minerals, etc. Which can break down which indicates that the basic units are not Legoland uniform and some rare harmonic imbalance can undo the structure = Entropy. The energy packets, because they are Electro-Magnetic invoke a binary logic (attract/repel, etc). Every manifestation is based on that rock solid foundation.

The subtle mechanism of gravity is produced by the etheric aspiration flow of the substance, of the electrically neutral masses. The etheric suction flow of the substance is produced by particles in the depths of the substance, in the nuclei of atoms. Nucleons by their very fast rotation (10 ^ 20 rot / s) behave like centrifugal vacuum cleaners, which suck the ether with very low speed (2.78.! 0 ^ -7 m / s) through large sections around the axis of rotation. and repels it at high speed (3743 m / s) on the periphery, through very small sections. The ratio between the velocity of the etheric aspiration flow and the velocity of the etheric discharge flow is given by the nucleonic gravitational constant, which is Gn = 8 / (4.pi.k) = 8.eps0. This shows that the gravity is derived from electricity. The etheric suction flow of the substance (of the masses) generates in the surrounding space the depression that generates the universal gravitational pull of gravity.

No, photons do not communicate the EM force, which is ascribed to virtual photons, but these are mathematical abstractions that show up in the perturbative description.

[@AA-eq5wk]

the curvature only localizes the "action at a distance." That is why when objects fall from low orbit toward the Earth they build toward terminal velocity the closer they get to the surface, which is consistent for all objects. Gravity is entanglement... of positive and negative equalization. So elementary positively charged particles are universally entangled with all negatively. So you have universal entanglement down to localized entanglement where a planetary mass, not only is warping space, but is a localized (current duration) entanglement of waves... as waves packets, objects, are lifted above the earth, they lose entanglement with the localized, planetary, mass and get more entangled universally with particles (waves) out in cosmos where they originated earlier in their duration or "at a distance," so that is why the object weighs less or the Earth weighs less when the object (wave packet) is no longer entangled with the planet

What's funny about gravity, is that the image of everything we see in the sky is delayed. Even our moon is not where it appears to be, as it takes time for the light (and gravity) of the moon to reach us. We're attracted towards the past. We're pulled physically towards the past - towards the shape of how things were, as oppose to how they are. And that makes expansion of the universe a much bigger mystery. Shouldn't the fact of delayed propagation of causality be decreasing entropy? But no. It somehow increases, even though all forces that propagate, point towards the past configuration.

[@djdrocco]

If you're asking about the compression and expansion of matter objects caused by gravitational waves, then yeah technically, propogating through matter should cause infinitesimal tidal forces within the object as its component particles react to suddenly being alternately closer and further away from each other. As I (barely) understand it, this should rob the object of some vanishingly small amount of angular momentum, but also heat it up a similarly tiny bit. I don't think gravitational waves have a push/pull effect with regards to an object's velocity, since the wave itself imparts no momentum to matter it moves through. Someone with a more accurate GW model in their head will hopefully be able to tell me how wrong I am and why.

SpongeBob SquarePants. Forget everything you know and concentrate on fine dining. Here is the equation you need to understand. F=ma. Since a hammer and feather fall at the same rate in a vacuum, the mass contributes zero to the force. So it becomes F=0a. Anything times zero is zero. No external force is acting upon the apple. The apple doesn't fall, it stops accelerating. The laws of physics are the same in all frames. A car being towed and the cable snaps. What happens? The car is no longer being accelerated so it slows down. An object in motion stays in motion until acted upon by an outside force.. Force decreases with distance. The car is slowing down because of rolling resistance. The apple is slowing down because of air resistance.. The earth is spinning in a circle so your trajectory through space is curved. It's basically two runners on a track in the same lane one stops accelerating and is run into by the following runner who then accelerates the first runner. Since the air underneath the apple doesn't have enough force, the apple keeps slowing down as more runners come up from behind to accelerate it. In an infinite universe with everything spinning in circles, which direction is up? The direction with the most acceleration. The greater the radius, the more acceleration there is. Newton had it right with his Laws of Motion. With Acceleration as the frame of reference. But then went on to use mass as the frame of reference and physics as been using the wrong frame of reference ever since..Mass doesn't curve space. Motion curves space. Motion is acceleration. Newton's Laws of Motion perfectly explains 'gravity' when properly understood.

If the space is empty and it is evenly distributed. When it falls and concentrates and compiled to itself it becomes matters. All matters stretches the space around it and that is the gravity field. When the matter becomes a giant ball like the earth, it stretches the space around it so we feel the pull. It is a curvature of time and space. Assuming the earth is not spinning, we would feel the same gravity pull. However, assuming all of the sudden the gravity disappears on the earth, all matter and us should be going back to it original located in the fabric, that would be like being shot outward in all directions as if we all being exploded from the center of the earth outward in all directions. We then would stop at a point when the earth was smaller than dust like a giant plume of cloud in the solar system. Why two objects attract each other? Because when one enters the curved space of the other object, it falls to closer and closer to the object because at the curved point it gets closer to the object, it will continue to get closer and closer to the object until it touches the object because it cannt fall anymore. That is gravity and that is how gravity works! I think I got it ! 😂😂😂

dont know what gravity is , but its a good thing its exists

[@janmiller839]

Gravity is not a propagating wave, it is an attractive force, and it seems to be dependent on speed and distance between the objects.

It's 2022, not 1902. Stop posting that BS.

I asked that exact question in third grade! I'm now in my 60s and still have no answer?
