Will Emergent Gravity Rewrite Physics?

the degree of expressiveness you use in your voice not only makes the speech much more interesting, but also simplifies the understanding of the concepts! Really good!

Refreshing to watch science content that is human narrated and not TTS. Thanks!

Gravity is one of the simplest things to think about.. at first.. but if you keep thinking about it, it gets trippy!

So, if I understand this right, the fundamental problem with emergence is that, as we zoom in on deeper layers, we can't observe enough of those deeper layers to give us enough information to discern how they translate to higher layers. I think that it's like the coastline paradox. The length of a coastline is almost infinite, depending on the resolution that you're measuring it at. The higher the resolution, the deeper you're going in its "layers." If you measure it from space, then you can see the entire thing easily, but if you were measuring it at an atomic level, it would be almost impossible to gather enough information to form a coastline at all. Increasing resolution without increasing total information gathered naturally decreases the area that we can gather information at. It seems to me that the issue with emergence is of that nature. Looking at clouds has an incredibly low resolution, but we get to see the motions of the entire cloud. Another way of looking at it, I'd say, is a little like Heisenberg's uncertainty principle. It's almost impossible to gather information at both a very high resolution and a very wide area. That's my hypothesis, anyway.

Personally gravity doesnt worry me much except when I go to get up.

You know what else has layers? Parfaits.

When you asked me if I had air around me, I choked on my shredded wheat 😂🤧

A superb explanation of difficult ideas. Easy to grasp, excellently narrated. Congratulations!

14:46 "Black holes care more about surface area than the volume etc." maybe not so weird. There are analogous things down here, like the skin effect, the idea that current in a wire , or conductor, doesn't actually flow INSIDE the wire, but only on the very surface, and reason is actually pretty straight forward when you think about it. The metals atoms on the surface do not share their outer valence electrons in the same way as the ones INSIDE, the ones surrounded by other metal atoms, so the ones on the surface are "free" to be charge carriers. This new science of topology regarding materials has opened up whole new avenues in meta materials , magnetism, superconductors etc.. It is understandable from that perspective how the bulk volume of a black hole would be completely different in properties than the surface. People get the wrong idea of a "black hole" as being some infinitely dense endless thing it really isn't, all the mass is still there, it can't behave in a classical sense because all the electrons they're not there to behave like normal matter that can absorb a photon and re-emit it as light of some wavelength. And the gravity well isn't some infinite value, just a large one or a strongly curved region of space time, I doubt the universe has any examples of infinity, that's a human invention.

Please do a video on black hole thermodynamics! I absolutely loved this.

Awesome, I learned some stuff, and love the presentation in terms of science communication. If I requested one thing, it would be to eschew all of the video clips except for those that contribute directly to the content; there are a couple diagrams that I found fascinating, while I found that not looking at the rest usually enhanced my focus on and understanding of the content. Perhaps it'd be neat to try: The nifty audio spectrum graphic, with any desired slides put up for at least 30 sec -- first full-screen and then on "a window in" the audio screen for a few moments until it finally disappears, for an easy to follow transition.

Ogres are like Onions. They have layers... What about Parfait?! 😂

Love the content, I especially appreciate your editing style! Very conversational and more easily allows for digestion of kinda heady topics like this as opposed to a perfectly executed script or getting rid of all the filler words and pauses. More of that please @ all content creators lol

Thanks for another entertaining, educational, and detailed video! I always enjoy how you are willing to make longer videos in order to do justice to a topic. I recently saw an article about the Fourier Transform. It reminded me of this video. Is there any work being done on trying to apply a quantum version of the Fourier Transform to the idea of emergent gravity, similar to the way a song can be modeled as the combination of its component waves?

emergent gravity is a great modification to standard ways of thinking gravity. I think there is a further change in notion of gravity that is possible and more compatible with the standard model.

One theory says time is an emergent property of entropy. Someone has to figure out how Time and gravity are both emergent properties and keep coming up as interrelated phenomena. It appears Eisenstein does not fully explain it as I understand it.

I thoroughly enjoyed this. Very interesting. There’s much to think on. Thank you so much for sharing this with us all.

3:27 There is so much physics and quantum physics in modern chemistry, without it you couldn't even dream about having that level of understanding of chemical processes we have today.

I hope that you continue to put out educational content. Your narration has something to it that I can not explain.. its like all the aspects of your presentation perfectly interact and speaking excellence simply emerges.

Way better then string theory
