      @@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.

    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.

      @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.

      ​@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.

    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.

      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.

      @@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.

AI is developing non-linear, logarithmic like, it's hard to predict when any breakthrough will come or be announced.

We had the physics to land a rocket back on land far earlier than when we were actually landing rockets back on land, so the gap between the world that we know & the world that we can physically create is massive.

    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.

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."

    I feel one thing that fascinates is the methdology. I have a background in economics and physics has influenced economics a lot, but most of it is still stuck in Newtonian physics, so this search for a unifying theory fascinates me because one of the reasons why we might never have a unifying theory is that what if there are some things that cannot be perceived neither by our technology nor by our mind? This is my bias as someone with a background in economics (I don't consider myself as an economist, that's why I'd rather use that word), because the economy is like that, understandable, but ultimately unknowable (in the sense that a person cannot fully understand ALL its aspects - the history of economic thought show that economists once believed they could find the levers of economic growth and freely manipulate them) in its size and complexity.
    Like, imagine an alien scientist saying to a human one, "By the way, did you see what the yoaplmea particles did there? Pretty wild, huh?" "What are those?" Due to the scale of the theories and practical impossibility of testing in a lab, more and more mental experiments are necessary, but these are limited by our human imaginations, even though more and more data is being observed to inform these mental experiments. What if the answer might be something so trivial in hindsight that the bigger question is why we didn't notice earlier? What if the answer is something so incomprehensible that not even advancing the technology to its highest level possible would make us only scratch the surface of reality? And yet we try, this is what makes science such a beautiful thing.
