Quantum Gravity

While there are many challenges facing modern particle physics, perhaps the ultimate one (and certainly among the most difficult) is to describe the nature of gravity in the quantum realm. Despite a century of effort, scientists have had only the most cursory of success. In this video, Fermilab’s Dr. Don Lincoln talks about the idea of quantum gravity and sketches out the need for this difficult advance.

THE ULTIMATE (AND CLEAR) MATHEMATICAL UNIFICATION (AND PROOF) REGARDING PHYSICS/PHYSICAL EXPERIENCE IS NOW DEMONSTRATED, AS E=MC2 IS F=MA: TIME DILATION ultimately proves (ON BALANCE) that E=mc2 IS F=ma, as ELECTROMAGNETISM/energy is gravity. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. (Importantly, balance and completeness go hand in hand.) The stars AND PLANETS are POINTS in the night sky. NOW, A PHOTON may be placed at the center of WHAT IS THE SUN (as A POINT, of course); AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=MA; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. GREAT.

How can you call yourself a scientist, if you can't handle criticism? Part of the scientific method, is falsification. It holds that every theory is falsifiable based on new observable evidence. This is particularly true when technology is constantly creating new scientific instruments capable of providing new data never seen before.Einstein's theories should be just as falsifiable as any other scientific theory. Perhaps the "anti-relativity email" you refer to is not valid, but, that doesn't mean something valid isn't out there. Until a theory of gravity that works comes along, every theory of gravity should be considered.

How long would it take for an electron spiral in to the photon by emitting gravity waves. Sounds like that can be calculated

[@seanlynch8339]

That can be calculated in a naive fashion, but would be meaningless, as electrons do not really 'orbit' the nucleus. That is not what the video was talking about. time of decay (due to gravity waves for massive bodies) = 5 (a^4) / 256 * M1 * M2 * (M1 + M2) where 'a' is the distance between M1 (mass 1) and M2 (mass 2). This will not work for electrons as electrons do not really 'orbit' The video was talking about the electron orbit's decay die to radiating away electromagnetic waves. There used to be a model of atoms as little 'solar systems' with electrons in orbit around a central nucleus, like planets in orbit around a sun. This created a paradox that led to the development of quantum mechanics. When a body, like a planet, is in orbit around a much larger body, the planet is constantly accelerating. The planet may be going around the sun at a constant speed, but velocity is a vector with both speed and direction. Since the planet is following an elliptical path, it is constantly changing its direction, even if the speed is the same. We'll leave out gravity waves for now. Charged particles, like electrons, emit radiation when they are accelerated. The radiation is in the form of electromagnetic waves. look up the Larmor Formula for more information on how to calculate the power radiated by an accelerated point charge. If you picture an atom like a tiny solar system with an electron in orbit around a nucleus you know that the system is stable because the electron's orbit does not spiral down into the nucleus. The 'velocity' of the electron must be 'fast' enough that, even though it feels a strong electric charge attraction to the protons in the nucleus it has enough velocity to maintain 'orbit'. However, a body in orbit is a body that is constantly accelerating, and a constantly accelerating point charge is constantly emitting electromagnetic radiation. The radiation means that energy is leaving the system, and the expected result is that the 'orbit' of the electron would decay and spiral into the nucleus. It does not decay. It does not emit radiation (due to its 'orbit'). It is extremely stable. Quantum mechanics was developed to explain the 'orbits' of electrons. the term 'orbit' was kept, but it is not like the orbit of a classical body. It is an energy state that the electron and nucleus system can exist in. The states are discrete, or 'quantized' in that an electron can be in one state or another, but never an in between state. It can be in state 1, 2, 3 but never in state 1.79. When an electron moves between states it either emits or absorbs a photon of the exact wavelength (a measure of a photon's energy) needed to jump the electron from the beginning level to the final level. (this is the origin of emission and absorption lines in spectrum analysis) Since the electron is not really in orbit, it does not make sense to calculate the gravity waves generated by its orbit. You can find a formula for calculating the time in years for two massive bodies in orbit around each other in equation number 44 of the following paper: www.tapir.caltech.edu/~chirata/ph236/2011-12/lec15.pdf However, this does not really apply to electrons and a nucleus, because we know that electrons do not orbit the nucleus. If they did, they would radiate and matter all would decay on timescales of seconds. We know matter is pretty stable, so the idea of electrons in orbits is not accurate. It may be something our brains can picture better that quantum wave probabilities, but nature is under no obligation to care about what we humans feel comfortable with being able to picture and understand.

I am really having a hard time with this. If gravity is curved space ( around a massive object ) then we do we need a force carrier at all for gravity?

[@cazymike87]

Because there is no such thing as force! Not in the way that you visualise . What you call FORCE its just Fields that are vibrating . This fields are every where. Matter is just energy entraped in a closed space . This energy cannot be destroyed or created and wants to fill every space of this space evenly . When this energy its reaching 0,5MeV then the electron field start vibrating and imediatly creates a particle thats its called electron. And so on for every single of the known particles with different energies too. You try to move this particles then ( an electron lets say ) , at the place in space where this wave move it econters another particle . If this particle is charged then interact with it , and that means that at that 3D space point there is more than just 0,5 MeV. That means that outher fields start to vibrate and so a quark starts to emerge lets say. If you can name me a single particle that stay at rest (and not moving) I will admit that I am wrong. Why a particle must allways move? because particles and forces , given that forces derives from the interaction between particles , are just excitations in this Fields , and that its why particles are wave . Because fields move in a wavey form.

[@cazymike87]

Those wavey form are the forces ! That its why Gravity needs its graviton (its gauge bosson ) because those wavey form are mediated by the gravitons that moves a long those wave lengths .

You were talking about the electron spiralling down into the proton in an atom but given that gravity is so weak, as you said like 100 trillion trillion trillion times weaker than the strong force, then surely the time scale upon which this would be so large that it would mask the age of the universe easily and too long a time and small a change that scientific instruments probably cannot measure it

[@theultimatemotivation2800]

the electron would spiral down because of the elctromagnetic radiation he creates (which causes a loss of energy) and this has nothing to do with gravitation. the answer to this (false) prediction lies in the principle of quantification of the levels of energy within an atom.

[@notagainstgod]

A little bit like some basic one dimension chaotic attractors for which it could take an infinite time to reach them. Take a particule for which when it is at position x, its speed is -x. (Don't ask me how it is possible, it is just for illustration.) So, when the particule is in the negative positions, its speed is toward the origine, and when it is in the positive positions, its speed is also toward the origine, but such a particule will never reach the origine (unless it starts there). It is linked to convergence/divergence of infinite sums. So, indeed, it could take an infinite time for gravity to accomplish the described goal, but the "reason" explaining while the electric attraction forbid it in the first place, while being much stronger, would still forbid it, anyhow...

[@Florreking]

That is a thought experiment to show how classical electrodynamics fail to explain the observed fact that they dont spiral in to the nucleus, which is solved by quantized energy levels, you can apply the same thing to gravitation, sammbos argument is that even if the electron would radiate gravitational waves, the effect is so small it wouldnt me measurable.

The picture of an electron in a planet-like orbit and spiraling in was an example of how you CAN'T use a classical theory to explain the structure of atoms, and need a quantum mechanical theory.

[@yoondami1127]

Because he had to explain the electromagnetic force interactions between the orbiting object and the centre. Emission of energy will ultimately lead to the orbiting object falling into the centre, just like how a neutron and an electron are together.

[@Lucius_Chiaraviglio]

@@yoondami1127 But that's the thing: In any atom not subject to electron capture decay, electrons CAN'T emit energy to fall all the way in to the nucleus -- the innermost orbital not already occupied by other electrons is the lowest orbital an electron can enter with the release of energy, and any attempt to get an electron to go into a lower orbital or to confine it to the nucleus consumes energy. Note that electrons and the components of nuclei are fermions; bosons would be able to spiral all the way in. This doesn't work in gravitationally-bound systems on a macroscopic scale, in which orbiting objects can spiral in with emission of gravitational wave energy limited only by collision of the objects (or in the case of black holes, complete merger). Supposedly down at the scale at which quantum mechanics begin to dominate, fermions moving according to gravitational interactions would start to obey the same rules of quantum mechanics (and orbitals derived therefrom) as fermions moving according to electromagnetic interactions, but currently we have no way to test that.

[@wevegotcookies]

Thats because the theory itself doesnt exist yet. but our current theories predict that a gravaton should exist as explained in the video. the thing is that its force is so weak that it is near impossible to detect on the quantum level. So in order to gather enough information, or any information at all, to get a theory on it we have to use black holes or other points of large amouts of mass in a very small volume. Because it is in that place we might find that gravatons have an influence on the quantum level.

On the old times called "eter". This idea was abandoned because nothing was found on vacuum, however no further explanation was given about how wave propagation occur.

This is called neutrino oscillations and thus has an extremely minuscule amount of weight. - This is the missing universal mass preceding that of the Higgs-Boson - the masses of other matter particles, generated by coupling to the famous Higgs particle, vary widely - from the electron, about 2,000 times smaller than the mass of a proton, to the top quark, which weighs nearly 200 times more than the mass of a proton. The neutrino mass, however, is at least 10,000,000,000 times smaller than the proton mass hence it is referred to as a WIMP. - Most people will have heard of electrons, neutrons and protons - and perhaps even quarks, which make up the latter two. But to me, the neutrino is the most amazing fundamental particle. They are everywhere. About 65 billion neutrinos, produced by nuclear fusion in the Sun, pass through every square centimeter of area on Earth, every second, without doing much of anything. - Formed in the first seconds of the so-called big bang, the CNB is a dark, invisible candidate for the seat of electromagnetic phenomena. Like the Cosmic Microwave Background, the CNB can provide a universal rest frame and, at a temperature of 1.95 K⁰, the CNB forms a frictionless superfluid that permeates space. - Recent experiments suggest that the electronic neutrino is a tachyon - a tachyonic CNB is also a dark energy candidate; while, at the same time, analogous to cosmology‘s - quintessence‘. (Aether - Quinta Essentia - Prima Materia) - Question is could it be really be an Aether candidate and would it not be the best substitute for the cause gravitational fields due density, mass and the electromagnetic field resistance of particles - i.e. generating EG fields (electrogravitics) - are they not much better suited as a gravitational candidate than so-called gravitons?

[@taariqm-star6162]

***** - Thanks for that anyway I am sure that there will be more mysteries to be revealed by neutrinos in the near future - what a blessing a unified field theory would be especially if it was as elegant as that - only more experimentation will tell - but I can't really see how general relativity will be included it though.

May be dark matter has something to do with the creation of gravity. ¨Since the information contained within a region of space depends upon the arrangement of objects within that region, moving the objects can change the entropy within the region. Verlinde demonstrated that this produces an entropic force that acts like gravity. From the basic idea of information entropy, one can derive Einstein's equations of general relativity exactly.¨ www.forbes.com/sites/briankoberlein/2016/11/08/solution-to-dark-matter-proposes-that-gravity-is-an-illusion/#27d5d1813058

[@einsteinvondaniken]

Not that I'm a physicist or anything, but I think they're wrong about both. I think it's more likely that gravity is an equal and opposite reaction to the effect mass has on space-time. They say time slows down, or drags, on mass. Well that's why matter can't reach the speed of light, right? Because as it accelerates it gains "mass" in the form of velocity, to the point time would slow down and the particles would become too "heavy" (massive) to accelerate any further. Or that's why they say flying around a black hole would cause you to age slower. Or why going faster than light would cause you to travel back in time. So anyways, if mass accelerating through space causes time to slow down, could time slowing down cause mass to accelerate? In other words, the gravity is strongest at the center of mass. So time must be moving slower at the ground than above head. That's why we are constantly being pulled or "accelerated" toward the ground. I know I'm sometimes all over the place and bad at explaining things, but my hypothesis works with everything. If time slows down when you move faster, (atomic clocks on airplanes) and bigger planets have stonger gravity (because more mass) and fat people weigh more (isn't weight really just a measurement of gravity?)... I dunno. I rambled at NASA about this idea, and they gave me a "atta boy, have a sticker" type of response lol so maybe it sounds crazier to others than to me. But in my mind, it seems more correct than following the curve. Because when I'm not moving through space, I'm just sitting here, I'm still accelerating toward the earth. That's got to be a reaction to something, not just a line being followed. Who knows. Whatever.

I'll just mention one error in your post. You say: "the gravity is strongest at the center of mass". This is false. For example, if you have a hollow sphere of equal density (a shell), there is no gravitational field anywhere within the shell (even at the center of mass), due to the shell itself.

I have a suggestion of what quantum theory could be. It assumes that multiverse interpretation of quantum mechanics is true and there is no such thing as collapse of wave function. Instead collapse of wave function is simply entanglement of observer with the particle, that's why from his point of view it looks like wave function collapsed, but it didn't. If this is true then we can calculate gravitational influence of a particle as an bending of spacetime in all quantum multiverses simultaneously. This theory would also explain existence of dark matter, as an influence of particles from other universes on our universe. This theory is also experimentally testable. Here is experiment to determine if it is true: Put 1 heavy object whose gravitational influence you can detect into an empty space. Put device onto the object that would detect quantum state of spin of a single particle. Make the wave function of the particle collapse. If the spin goes up, device will push the heavy object with some force to the left. If the spin goes down, device will push the heavy object with some force to the right. According to theory, what we did here is that we entangled the heavy object with the quantum state of the spin of the particle and if that theory is true we should be able to detect that the heavy object suddenly have 50% gravitational influence and at the same time there would be created bubble of dark matter with the rest of 50% gravitational influence of the heavy object going in opposite direction as the object, because the dark matter would be simply the same object in another universe.

Sir pls explain the whole particle physics in your channel so that I can have some basic knowledge on this.....

Will the gravitational wave detection data shed light (or future research based on wave research) possibly provide any insight into the graviton or is that purely classical in nature as well? Are all QM gravity proposals based on either closed/open strings vs loop or are there are there other models where these pop up as well?

I'm EXTREMELY disappointed I didn't pay more attention in science class (during HS) ... I freaking love this stuff!

Instead of one particle, gravity may get generated with two particles. More particles implies more gravity. It can have relativistic properties. At quantum level, gravity could be just letting other particles "form" from energy. Gravity could be related to stability, swarm properties and clustering without fusing.

Feynman looked at this idea, if I understand what you said. If you have written anything mathematical about this model I would be interested in reading it. His idea is sometimes called the "pushon" model. It doesn't agree with experiment. But maybe your idea is different. However, the further your idea is from the standard model and GR the less likely it will work. But I enjoy reading new ideas.

@@edwardlulofs444 I am not physics person, but software. I tried to reverse engineered what gravity could be just philosophically. I'm not using GR or quantum as base, trying to express my thought below. Gravity holds things together, so for that at minute level, there has to be non holdable entity, like energy. Energy has properties like harmonic or flow or vibration etc. If energy is not infinite then it may start to wear out eventually at some point in space, because of vibrations, flow etc. Gravity property could isolate wearing out and create a particle. Gravity could also cluster these particles so as not to get destroyed by energy, could be due to law of conservation. So gravity could naturally support swarm properties and clustering. It doesn't fully fuse entities due to either 'isolating other energies' property of gravity or it could fuse gravity properties in particles itself and then they don't fuse. Total fusion is energy's property. Effect of gravity may be observable only when two particles interacts, like momentum property, when a particle consists of more smaller particles. Particle purely implies "size" if it does not consist of other particles. Size is space property, implying presence of gravity everywhere in space in some form, similar to luminous eather. Just size property implies sheer presence, dominance and hence slow attraction property at distance, but nonlinear attraction in close proximity. Gravity itself could be hunter energy of weakness of other stronger energies. This is just a thought without any mathematical base or model. But this could be simulated on computers. It also implies bondage for energy and space due to which energies could start to wear out eventually. Different types of particles implies different amounts of wear out energy or presence of different energies. Humans have evolved in highly quantized world and see energies only through particles and photons. So we may not detect non quantized energy directly, even our devices are quantized. In double slit experiment, when electron passes through both slits, we can say that energy of electron start to wear out due to possible two paths and gravity creates two electrons from wearing out energy which then passes through each slit.

Classical calculus of gravity and particle physics have already been proven consistent. Idescribed the nature of gravity in the ancient quantum field at a certain Cheikh Anta Diop conference and presented graviton at g+ in 2015. Classical calculus of gravity and particle physics are already consistent in the reconstructed Pharaonic measurements of physical quantities. Dr. Don Lincoln takes us here in the right direction.

Kes Co Have you or anyone that you know heard of gravitational foam? I do not remember where I encountered the term and it is driving me up the wall trying to understand what physics may be in play and how it would display its self. Thank you.

I have so many questions. You should do a segment called Ask A Physicist.
