@@ArvinAsh Hello, I have a Problem to understand the Gravity and the Orbit of the moon. The Orbit does increase 3.8cm each year. Science says the moon speed is increased. But the moon has a distance of 400000km and the speed is 1km/s. Billion years ago the distance was 200000km and the speed was 1.3km/s. Result must be moon speed is getting slower. If the moon has no speed it will Fall down to earth. If moon speed is 10 Times higher it will Lost in space. Seems to be there is another force if mass is moved. And this force is unknown until today.

[@prajwalpreteesh314]

I like your lectures very much because it is understandable for ordinary lay man also. More than that your approach to know things and your curiosity to know more and your probing mind should be model for everyone. I have certain basic questions about Big Bang itself. The theory presumes a common origin for everything in the Universe. One can imagine something is responsible for the creation of something else. That is what we witness everywhere and on everyday. The theory goes against this basic tenet. How do you explain this ?

[@ArvinAsh]

Thanks. Well, if by "something" you mean laws of physics, then I would agree with you. A small seed can create a large tree, for example, by simply executing it's built in genes and using the laws of physics. You could ask, "where did the seed come from?" It came from another tree. Where did the tree come from? It evolved from lower forms of plants over a long period. Where did these originally come from? The were the product of the laws of physics working on the ingredients and environment available in the early earth, and evolved to more sophisticated forms of living things over time. The original "something" was the laws of physics.

[@DrDeuteron]

I think Dr Don (Fermilab) covered it. The amplitude falls linearly with distance, so a strain of 1e-20 at 1Gly would be 6e-7 at 1 AU, and 1:5000 at lunar distance. Pretty tolerable for the human body. From orbital distances (under 100 miles), we're long at 1:2.....sounds painful.

[@TheElectra5000]

I don't know if you already answered this on another vid, but what led to all the matter in the universe to make a big bang instead of a black hole?

[@cloudpoint0]

A black hole is caused by extremely high energy density, not just by lots of energy (or mass) being nearby. That energy needs to be able to fall inward towards a single point and collapse. Immediately after the big bang, energy wasn’t dense enough to make one ultramassive black hole, and it was getting less dense by the second due to rapid expansion making falling inward impossible. Possibly very small patches of the universe were dense enough and / or expanding more slowly, leading to some primordial black holes (but we haven’t detected any). Matter came after the initial moment of the big bang, matter was created in stages by the unfolding of the big band.

[@cloudpoint0]

@YAMERO CAT They are not my ideas. They are what many or most astrophysicists will tell you. I think point 2 is the only one that you might still hear some old school opinions expressed about (ignore them). 1) There is no physical singularity anywhere either before or after the event called the big bang. 2) The universe didn’t pop up -it always existed - but there was a phase transition 14 billion years ago. 3) Black holes form when too much matter (mass) is together in a small volume and gravity pulls it all towards its center of gravity where it collapses into a void (again no physical singularity, just a math artefact). 4) We don’t know how supermassive black holes formed but repeat mergers of small stellar black holes is the most likely explanation - small black holes are heavy and fall to the center of galaxies. 5) Scientists infer a black hole’s mass by how it tugs on the stars around it, and they know the sun’s mass to use as a comparison - this is well-understood physics. 6) Light isn’t sucked - space and time coordinate sort of flip around inside a black hole so escape means travelling backwards in time and that’s not possible, even for light. 7) The previous point comes from general relativity theory, the inside cannot be seen only calculated. 8) I didn’t say things with mass don’t attract but other forces can overrule that attraction and keep two things apart - like the earth and the moon, or all the very tiny stuff that came just after the big bang. 9) Dark matter is helping hold the galaxies, etc. together but dark energy is trying to push things apart (dark energy is slowly winning this tug of war). 10) Heat death is our future.

Space is an energy field with uniform energy density. Mass changes uniform energy density balance. Energy density increases towards Mass & decreases away from mass.

When mass moves these crests & troughs also move generating gravitational waves like EM waves produced by motion of charge. Gravitational waves propagate through space at light speed for which space act as a medium.

[@jasemalhammadi4228]

Arvin, Do you think that the universe could be a massive invisible ocean where all celestial bodies swim through? The maximum speed in the universe is the speed of light which happens to be the speed of the gravitational waves propagating in space. Could it be that light (massless photons) can only travel at the maximum speed limit of the universe which is the speed of the medium it travels through creating waves in space time in its wake. This probably explains why light has the duality of wave-particle nature. Could it be that light is made of particles but the waves it creates in space-time (gravitational waves) are mistaken to be intrinsic to light? Apparently everything in the universe move as ships riding waves they create in the ocean of space-time. This approach may explain many phenomenons like the double slit experiment.

So a gravity wave would presumably be stacked planes vibrating at normal in the direction of travel?. Colour or grey level coding of near v distance points helps with perspective.

So, regarding the theory about the Higgs field moving to a nonzero minimum after the big bang. This would mean before this point, gravity did not exist. If this is the case, how did all matter in the universe happen to converge at a singularity before the big bang? Could there have been another force, before the existence of gravity, that would gather all matter in the universe? After some light wikipedia reading of the Higgs boson, I've given thought to the idea of imaginary mass. We already have the common conceptions of matter and anti-matter, but I think it is possible that the value of mass exists not just on a single dimensional line, but other imaginary dimensions as well. If the mass of atomic particles comes from the binding energy of quarks, then those quarks that are not sustainably bound in our universe may exist and be able to create mass in a different axis, unobservable to us. Then, could some quantum phenomena be explained by extradimensional mass decaying into our reality? Perhaps, before the big bang, was a universe where elementary subatomic particles did not exist, and there were only quarks dancing about at lightspeed. Just some uneducated sci-fi thoughts. I don't understand the Higgs particle enough.

Thankfully there are way more educated and hungry people out there who allow us armchair enthusiasts to at least experience great minds.

why is gravity referred to as a wave but as we know its is a membrane like structure which holds space and time why is it that gravity converts space into time like heavy object less time why cant other forces do so ?

[@ritemolawbks8012]

1. "why is gravity referred to as a wave but as we know its is a membrane like structure which holds space and time?" In General Relativity ("GR"), when the local distribution of a) matter, b) radiation, c) momentum/energy densities and flux, and d) vacuum energy and pressure changes, it distorts the local geometry of spacetime. We don't have a testable theory of _Quantum_ _Gravity_ _Fields,_ so GR is the most accurate approximation using continuous math functions rather than discrete "countable" unit. When the spacetime geometry changes, it propagates as gravitational waves or "quantized spacetime curvature." 2. "why is it that gravity converts space into time like heavy object less time why cant other forces do so ?" Gravity is different from the other fundamental forces because of the equivalence principle of GR. That means curved spacetime is identical to accelerating in the flat spacetime of Special Relativity ("SR") and Newtonian Gravity. You can still use Newtonian Gravity Fields to get very accurate approximations, or use SR and gravitational acceleration. The problem is gravity must propagate at the speed of light. In Newtonian Gravity it travels instantaneously.

There was No Big Bang. No begining and no ending. Each universe is born from the ashes of a former universe. When the universe ends by a sudden retraction of light, all collides very violently, what is left is water, and a black hole. The black hole left is the remanant of information that wasn't erased, and it is a unique one black hole. The universe is racing toward a reunification of all black holes in a single one, with a ring of fire. (Hell) Outside this black hole is a progressive enlightening , departing from the ring of fire, then water, then the Source. This is the situation at the end and begining of each universe. The black hole as its name suggests is a hole in the fabric of eternal light, with no space nor time. When a universe is reborn, sparkles of light pop in from the exterior of a completely destructured time space fabric, these sparkles pop like stars in the bubble, at many places and begin creation. These sparkles bring very powerful light, a stairway to heaven, from outside space time and recycle the leftover information. the entering of light is very gentle, like a kind wind, but it is the reaction to the presence of light that awakens the void, makes it collide, stars, galaxis...Not in one point, but in several points at the same time. It is God sewing the hole in eternity with threads of Gold... Imagine a black ball, filled with black too, and threads of light piercing the ball and entering it at many places. Imagine that the black fabric inside the ball begins to move and stretch to prevent the threads from getting out, that is precisely how a universe is born.

Compound that on the "evidence" presented about the CMB which violates the laws of thermodynamics, and common sense, i.e., how do you eliminate everything "in front" of CMB measurements to come up with differentials so small, (8 decimal place variances IIRC) it could be measurement error or data processing artifact? Did anyone account for the "CMB" water in the oceans emit, and the CMB in Romania or in Eastern Europe somewhere far away from the ocean that showed ZERO CMB variability? I like Mr. Ash and his videos. I'd just like for him to include his stuff in context to the amazing amount of information that should condition his presentations. He _has_ done so with some things he presents, to my great praise, because out of context, all that happens is ppl revert to listening like at the foot of a guru, not a scientist trying to figure out the world around us. No one is infallible, that's why there's a bedrock tenant of science: reproducibility (something that current age scientific studies are approaching zero... no bueno). There are no "Appeals to Authority" in science (ok, there is, it's called scientific progress by tombstone, i.e., until the old guard freakin' dies, no scientific advancement happens because they snuff out all challenges to their invested theories but that shouldn't happen with the general public (nothing is every beyond question, that's a foundational principle of the scientific method and the logical fallacy of the appeal to authority: (s)he must know just because, they are a public figure, a person referred to with deference, etc., which by itself doesn't make what they say beyond vetting. That's the whole scam of experts when you see them on TV. Why cigarettes used Doctors to sell their cigarattes, and why Silicon Valley bans credible ppl first, because they can influence ppl more powerfully. Think deeper)). For a theory to maintain itself, it has to hold true for _all_ challenges, but it takes only ONE falsification to end its life. That means the existence of one falsifying data point, ends a theory's life. Imo, the inability to answer the question of how they could remove the signal of all the galaxies, and other things "in front" of the CMB is one of them. The other is the emission from the ocean by the detectors is another. Never discussed, catastrophic information that should be answered, honestly. Especially, if the only evidence of a proposal by a priest (let there be light, bang), is the one that created this avenue to go down, and it's only evidence is the CMB. Might as well propose the Ether, Celestial Spheres, or Climate Change.

@@vedantsridhar8378 It took until I started to read Medical Textbooks for me to realize I have the right to understand things in context. To this day, (I was a temp executive secretary in the late 1980s and I brought stuff to read) I will always remember a text that stated: "We know this. Given we only know this, apply that in cases like this." I thought, oh crap, docs don't know everything and they are just doing the best they can to mitigate their ignorance... That's all I expect from every doc, even if they're PhDs and they are Physicists.

So if the gravitational waves are everywhere like the CMB are we looking for some kind of a gravitational resonance that is everywhere? Thanks for your content it is fantastic 👍

[@tonywells6990]

@@DrDeuteron Hopefully there's a signal in that noise.

[@DrDeuteron]

@@tonywells6990 I don't think so, but there's still information about the physical processes that can be deciphered from noise statistics, e.g. white noise vs flicker noise and so on, also the magnitude, autocorrelations, variance, etc etc.. But the burden is then on the theorists to explain it, if the experimenters can measure it.

is it possible for gravitational waves to move something on earth? What if the source was close?

@@anotherJamesW With LIGO a 1B ly distant BH merger moved the mirrors by 1e-19m. (a proton is 1.6e-15m wide). Displacement is inversely proportional to distance (not squared).

If you were within a few thousand km the gravitational waves would probably be able to break your bones!

I donot know publishing in THE ROYAL SOCIETY

[@kabirsethi2608]

Just asking, Is there any way for us to generate gravity waves that could be detected by a device such as this?

[@AnthonyGoodley]

We all have mass and mass affects space in the form of gravity waves. Ligo is only able to detect huge events like the merger of two black holes for instance. I seriously doubt that anything a human does, let's say with an average weight of 150 pounds, could create a significant enough gravity wave to begin to move the needle at Ligo in a detectable manner.

[@ArvinAsh]

Yes, gravity waves are created from any Accelerating mass. Accelerating trucks create gravitational waves that interfere with the detector.

[@AnthonyGoodley]

Well I stand corrected then. I did know that human activities interfered with Ligo. But I thought it was more along the lines of false positives.

[@atheistaetherist2747]

We can generate Newtonian GWs, by spinning or rotating a dumbbell etc. And i think that LIGO would detect such GWs if the source was suitably located. And such detection could easily be used to show that GWs travel at over 20 billion c. They dont travel at c.

[@eljcd]

Well, actually: "Gravity waves are waves generated in a fluid medium or at the interface between two media when the force of gravity or buoyancy tries to restore equilibrium. An example of such an interface is that between the atmosphere and the ocean, which gives rise to wind waves." wikipedia.org/wiki/Gravity_wave Please people, be precise with the terminology! We are already stuck with BigBang, BlackHoles, DarkMatter and DarkEnergy, don't add GravityWaves to the list!

[@gettothepoint_already3858]

Good to see you here again Arvin. Great video, excellent graphics and presentation (as usual).

When I started to watch the video I thought I will comment asking "Why don't we create a system like LIGO in Space ?" good to know its happening and respect to Arvin Ash for explaining this in such a brilliant way! Btw , I was wondering thinking a stupid question that we can observe Electromagnetic waves by instruments like Telescope, will it be impossible to make a device that will be able to see or show us Gravitational wave ? I mean is it possible to find "Graviton" or whether it exists or not ? If yes , what can be a way ?

[@ramizr]

@@DrDeuteron but , we haven't really observed graviton in any accelerator or we don't even know whether it exists or not.Even there's no mention in the "Standard Model" . I was wondering how you said so ? I think we've mathematical problem with renormalization in general relativity. So , there's no complete quantum field theory i guess .

Big bang nonsense

[@samcena3942]

How can gravity as the weakest force overcome the strong force in vicinity of a black hole where the nucleus get ripped apart despite the strong force holding it together?

[@ArvinAsh]

Something like that might happen at the singularity, but probably not at the event horizon. But at the singularity, we really don't know what's going on. Possibly, all fundamental forces become one.

[@njm3211]

Arvin, why are gravitational waves limited by the speed of light since they are not electromagnetic in nature? Thanks

[@ArvinAsh]

They are limited by the maximum speed the universe allows. That maximum speed happens to be the speed at which massless particles travel. Gravity fits the bill, although we are not sure whether gravitons exist for sure.

[@YossiSirote]

If the universe is infinite then when it expands or contracts it remains infinite. It can never be the size of an orange. I think you mean our present day observable universe. But it is unclear.

[@ArvinAsh]

Yes, I probably needed to make that clearer. Thank you.

[@mercury9385]

Is the big bang a Higgs field excitation, from a true vacume to a false vacume?

[@ArvinAsh]

No. The Higgs field would have come into existence after the big bang.

[@who1989]

I've always wondered if the first gravitational waves were strong enough to form primordial black holes.

[@damo5701]

I've always wondered why it is said gravitational waves do not cause any time dilation, I suppose otherwise LIDO would not work....... maybe it doesn't? I assumed looking at the gravitational waves across the universe would be like standing on the shore looking at the waves across the ocean, how do we determine what created each individual wave, with any accuracy anyway?

[@lucaspierce3328]

The First Primordial Blackholes made the First Gravitational Waves as Black Dp-branes! The Matter/Antimatter Asymmetry and most aspects of Particle Physics especially the so called Coupling constants! Primordial Blackholes are the seeds of the Supermassive and Stupendously Large Extremal Blackholes located within the Centers of Most Galaxies!.

The Answer is Yes and the two are essentially one in the same thing!.

[@galahadgarza6905]

Arvin, how can even a space based interferometer detect an event that occurred 14.8 billion years ago (a one time event)? Do the waves continue to propagate from this event-like a tuning fork?

[@du5707]

Beats me. Like trying to detect the wave formed from a dropping a pebble in a ocean eons ago and from that of a wave formed by a tsunami today.

[@JohnnyAmerique]

@Michael Bishop They are detectable in principle. In practice though? That’s much more difficult. Detecting any gravitational waves is extremely difficult and requires incredibly sensitive detectors.
