Neutrino Oscilation is the secret behind the force of gravity. I know that for sure.

[@smlanka4u]

@@moodyrick8503, 99% energy released in a supernova explosion are neutrinos. Only 1% is light, etc. And it starts a few hours before (around 2 hours before) the supernova explosion. So that shows a connection with gravity and neutrinos. And gravity can be the hidden force that is coming out from the stars making the gravity and making a small and compressed object like a small black hole or a neutron star after the explosion. And neutrinos can go through any object making gravity and anti gravity showing only a very weak gravitational force. If nearby two massive objects are emiting neutrinos they will bend the path of neutrinos causing to become the gravity stronger, and come closer faster.

[@sethrenville798]

The only thing I wish it was different about this was that it was a little bit less specifically catered to what all of the academic scientists refuse to shy away from, even though their theories haven't worked for years. For real, though, even according to several physicist I've talked to, gravity is literally not even a force, it's just an effect that comes from massive object warping space time, like a marble in a bucket of Jell-O. This pushing out of the massive objects onto space-time causes it to compress, which causes it to have an equal and opposite reaction force, so depending on what frame of reference you feel most identified with, either way gives you the exact same results, with no graviton that has not, and will not ever be found, it explains why it's so much weaker, because, like space-time, gravity is an emergent property of the physical manifestation of the universe, and this bending of space-time also very easily and neatly describes both gravitational lensing and time dilation, as the space-time literally works like a lens, and the warping of space-time with in gravitational fields causes extra variables to have to be accounted for when the magnificent stroke of either entropy, or some underlying force that drives it, causes time to take forward and allows the wave functions of probability of the future to collapse into the various actualize states of the present moment. Extra computations locally means this takes more time than it takes someone else's local computation where there is less complexity to deal with, as reality very clearly will skimp on manifesting certain things if it doesn't need to, as evidenced by Heisenberg's uncertainty principle, the double slit experiment, and loads of other Quantum experimental data. The gravitational fields basically act as another set of eyes, causing wavefunction probabilities that would not have otherwise had to collapse to collapse into masses, so that they can properly interact with the gravitational field. If you're asking why, the best answer I think as to why is because if things did not go down this way, then randomly objects would stop interacting with massive objects, as they would simply continue being wave functions, which would keep massive conglomerations of matter, like stars and planets, from being able to form nearly as effectively, if at all. Basically, it happens this way because our universe is stable

Or visit a black hole. Perhaps gravity is the weakest force until you realize it can snuff our light

[@notaspeck6104]

@martinadoesthings Yeah but you realise how extreme a black hole is? If anything that’s proof of how weak gravity is. It’s still strong in large quantities but that’s not the point. If you take two electrons and place them apart they should be attracted by gravity and repelled by the electrical force. If you take the ratio by which it is repelled vs attracted you get an absolutely ridiculous number in the millions of millions of millions of millions and so on. So yea, gravity is by far the weakest force. I think you’re conflating strength with strength in numbers. The universe just has a shit ton of stuff in it for gravity to pull together. Personally it’s my favourite ‘force’ because of this, it isn’t particularly remarkable by itself but it’s simplicity and elegant universality is what allowed anything of interest to exist in the universe.

[@stewiesaidthat]

​@notaspeck6104 you are wrong. Galileo proved that mass does not attract. That mass is not an actionable force. But his flat earth peers dismissed it because without gravity, objects on a stationary flat plane would float away. Gravity is an emergent property of acceleration. What you feel is the resistance of your mass to being accelerated by an outside force. Newton's law of motion, F=ma. Mass TIMES Acceleration. Acceleration is what gives mass force. Mass does not create acceleration. E=mc. Acceleration creates mass. So no. Einstein is wrong about mass warping space and Newton is wrong about gravitational attraction.

35:10 - However protons are affected by gravity enough that tunning had been necessary in the LHC in order to compensate for soli-lunar tides, originally not predicted. So gravity keeps behaving as expected (even more so than some scientists actually expected) at such tiny scales. While quantum fanatics may have a theoretical objection to gravity being Einsteinially seamless at quantum distances, so far they have zero evidence for that, rather the opposite. Similarly the quantum hyper-sensible LIGO does not observe any anomaly on how gravity behaves at quantum scales, all the opposite. "Quantum gravity" remains purely theoretical, while gravitational effects even at the quantum scale remain fact for as much as can be measured.

From the video you might've got the impression that string theory (the whole multi-dimensional-brane-thing) is the cutting edge of modern theoretical physics, revealing the hidden truth beyond the veil of reality. This is not an accurate depiction. String theories are a collection of fascinating but speculative mathematical models that existed since 70s and didn't have a major advancement since the 90s. There's no single complete theory either, it's a bunch of different implementations, each trying to reconcile with this or that inconsistency. I wouldn't go as far as to call string theory useless, but any time its mentioned you have to keep in mind that it is speculation and there are no experimental indicators that it is a model of our reality.

As I understand it, gravity is a fundamental variation of time that results from concentrations of mass/energy. The gradient of this variation resulting in the differing paths through spacetime. Gravity is not necessarily a "force" but instead is a phenomenon that is the result of this variation of time proximate to concentrations of mass/energy. There have been many videos published that address this and this video, as good as it is, seems to ignore this apparently well established theory about the fundamental nature of gravity. Curvature of space/time especially time creates the phenomenon we experience as gravity. Particles such as gravitons or tachyons seem convenient for Star Trek, but unnecessary for the universe in which we live.

[@chrissonofpear1384]

Hmm, could just about pave the way to a unified theory, on, if not everything, then some pretty critical things, if so. How it'd link to hyperbolic and holonomic entanglement, may be another matter, though.

[@MediaBrainRecords]

I believe this to be correct. Gravity may be an emergent property like temperature. Ultimately gravity may be an emergent result of propagation of information through concentrated quantum fields. I believe the mathematical proof for this could come from Claude Shannon’s information theory and entropy. I wish I were a better mathematician so I could further explore this idea, but my hope is smarter people are exploring this now because I believe intuitively it makes sense.

[@Alex06CoSonic]

@@MediaBrainRecords Correct me if I'm wrong, but to me, this talk of "entropy" seems to me like one looking at an abstract painting and misunderstanding it as "just a mess of colored goop". One can only make sense of it with enough frame reference and explanation from the artist, perhaps. Then, the emergent patterns in the painting become obvious, and it is no longer just "a chaotic mess of color". I see the idea of "Entropy" in the same way. We try to cut up the constantly reverbing waves into tiny bits of "3D Universe" at a specific point in time (like taking a picture of interlocking waves and calling THAT a "particle" like what we call muons, gluons, etc.) to try to understand them (while also forgetting the infinitesimally small parts lost during the cut, which reside in-between said slices), because we think the entire reverbing mess is "chaotic" or "entropic" and not understandable, but it's not. The exponential waves that keep hitting themselves and causing a "reverb" like soundwaves hitting the wall, then mixing with the same soundwave being emitted from the center once it's coming back towards the center, are the same thing as The Universe. The whole thing vibrating back and forth is causing emergent behavior we see as "The Universe", it's all organized, it's not "entropic". Entropy really seems to me like a misunderstanding. Am I correct, or am I going crazy? x)

Thank you, I think you've fleshed out some of the leaked gravity theory that I'd heard of before. Wasn't sure I understood it the first time. I guess one has to be able to think muli-dimensionally to understand such abstract concepts. I'm not good at it but I try.

[@christianheidt5733]

Fabulous presentation, thk you! Just subscribed

[@marcus8036]

Another masterpiece! Thank you for making these videos for us to enjoy

The fact that TON618 has the mass of entire galaxies is mind blowing

[@Aztesticals]

Il never forget when I was sitting in class in collage and were going to start going over the nature of space and I suddenly thought I had made a breakthrough before class trying to find a way to make gravity make sense to a bio student. Space was just a fluid with inverse density properties. More mass (more energy) decreased density and space contracts and wrinkles (bends) as it contracts proportional to distance from center of energy. Less mass (less energy) made space expand aka dark energy. And my teacher said, "congratulations your about 100 years too late. You came up with relativity."

[@jasongann8535]

Are you sure you went to college because you can't even spell it correctly.

[@denispol79]

5:40 Man, size and mass of a TON618's supermassive black hole are not the same. While its mass is comparable to Milky Way, its size is only about the size of our solar system. So the answer is d.

[@rinkelimuru]

i do want to add that ton 618 is not as large as the milky way it is larger then the sun hell even larger then the solar system but its not 100k lightyears long theres a massive differance in scale there nice video though. edit: also i might have to clear up that the 66 billion mark is not the "size" its the mass of ton 618 meaning its 66 billion solar masses

[@ZenRyoku]

shyte... i thought it was actually 400 billion solar mases... well... 66 billion is still absolutely insane!!!

[@PaulDormody]

He was saying it has the equivalent mass of our galaxy, but since it's a black hole, much smaller size.

[@ZenRyoku]

@@PaulDormody yes i get that... but its the the size that matters... ... its the motion in the fabric of spacetime... 💯 😎 THAT'S RIGHT!!! I SAID IT!!!!!!!!!! 😄😆🤣

[@trevorthompson1793]

This amazing channel demonstrates that there are many scientists who also understand the humanities. The way the stories are told is impeccable

[@Luke..luke..luke..]

Literally want you to narrate everything. 👌👌

[@SiqueScarface]

To test the equivalence principle, you need inertia balances, which accelerate the object and measure the force caused by the acceleration.

[@gyro5d]

Mediated to center of everything is Counterspace. Blackholes aren't created when a star explodes/implodes, the blackhole was always mediated to center of the star. Positive attacking Negative.

[@ollywright]

Very nice video! But to say string theory is gaining ground is inaccurate - it's quite rapidly losing ground these days.

[@JKDVIPER]

25:34 the edge is loaded with primordial black holes and quasars but these we haven’t seen yet.. trillions of solar masses

[@howareyou5899]

Einstein, renounced his German citizenship. Moreover, didn’t Germany refered to his achievements as Jewish science, and wanted to clear up German science from Einstein’s influence. Calling him a German scientist is revisionist.

[@youngneeson]

A bit of an overreaction. But okay, call him German-born then. The citizenship he held for the longest time is Swiss.

Tsar Bomba : 3rd degree burns in 100km radius Audio : Calm piano 🎹

[@seraphik]

this is really the most remarkable science channel on KZbin. incredibly well researched, written and produced. the only one that comes close is science clic, which is a bit more challenging in the concepts but not quite as gripping in the telling.

[@demoncloud6147]

When I run out of magic mushroom, I come here to watch trippy videos ! This channel is good alternate for magic mushroom

1666: Man is kept away from school for plague, he returns with what would become the groundwork of physics 2020: Man is kept away from school for coof, spents entire time eating cheetos and playing vidya. This is, indubitably, _the bestest timeline._

[@robinbinder8658]

wow. imagine being the boss of the whole operation. and 2 days in, not even fully operational you have to declare to your staff that you where successfull. they could have been waiting for years for all they knew... they mustve shed tears of joy

[@tantwister]

Love all of your videos. So well-done and educational.

[@eman85mph]

Putting parts together in so many new ways on my motorcycle as I listen to this and wrench on it 🔩🔧🤷‍♂️⚙️🤣

[@deusexaethera]

Fun fact: The Tsar Bomba explosion was so hot it melted _AN ENTIRE GLACIER INSTANTLY._

[@Net-Zombie]

What's this thing coming toward me very fast? So big and flat and round, it needs a big wide sounding name like 'Ow', 'Ownge', 'Round', 'Ground'! That's it! Ground! Ha! I wonder if it'll be friends with me? Hello, Ground!

[@martinhealy2902]

I was particularly fascinated with the discussion of gravity in the Planck universe, and the comparison with what we see now. Thanks for the vids!

[@Mckeycee]

@6:00 ton618 is comparable in size to the solar system not the entire Milky Way

[@BelieveOneGod]

Someone : Why is Gravity so weak? Gravity : do you want to die?

[@DeltaCodeGames]

Originally, the Tsar Bomba was designed to be a staggering 100 megatons, but then someone stepped in and said, "Hey, that's a bit much, don't you think?"

[@Andrijko85]

Such..incredible...quality. My God. Absolutely fantanstic. Keep it up.

[@johnrendle1303]

What a beautifully crafted documentary. A real pleasure to watch. Well done!!!

[@Lasagnaisprettycool]

I LOVE this channel but the ads playing in the middle of the video completely pull me out and make sure I just won't touch this channel while trying to fall asleep listening

[@chan400]

Thanks for the well researched beautifully presented episode.

[@jatinbangar4371]

You deserve a million subs mate. May you achieve your goal. Keep these content coming but take care too :)

[@natalie5947]

This is the most understandable explanation of membrane theory I've come across yet. Thank you very much for this. The quality is so high I can scarcely believe it is free.

[@marthike276]

This is marvellous. Compared to what's on tv now a days this is damn good.

[@justsomeguywithouthair5712]

Put this video on while trying to sleep,.42 minutes later, huh this is too good to sleep to

[@Greenmachine305]

Randall's ideas kick the can down the theoretical road.

[@PAULLONDEN]

31:19 For those who (like I myself) thought Lisa Randall was fatally tricked by gravity , she's still happily exploring particle physics .

[@mahelaniarektbb]

Thank you! I was just about to look it up.

[@mahelaniarektbb]

oh, they come back to it in the video whoops

[@Michael-sb8jf]

Too think there might be the possibility of some extra dimensional civilization wondering why magnetism is weak compared to gravity

[@F_L_U_X]

21:50 sounds like a Euler's Disk

[@STORMDAME]

Fantastic channel. So happy to have discovered it.

[@ranjittyagi9354]

Yeah, I discovered it recently. And, I love talking about the weather. Cheers!

[@titancloud]

I love how all these videos end with, “we just don’t know” and we may never know
