Because a lot of you are asking, I already made a video about the statement at 8:24 about 2 years ago: kzread.info/dash/bejne/Z3x_qpOTmqrbpKQ.html However, back then, I didn't go into as much detail as I do now, so you might consider the video too short. Rest assured, I _will_ be going into more detail in future videos. *This elasticity video was just the beginning of my deep dive into Einstein's Equation and General Relativity.*

Personally, I think the "well" visual is still useful for understanding gravity as the "warping" of space-time. The problem is that it's not usually explained that it's a _limited_ analogy, because spacetime is actually four dimensional, and most of the "warping" is actually happening to time, not space. Once I understood the limits of the analogy, it actually made a lot more sense.

This is a great way to put it. I dont like the analogy myself, but when I realized I didnt like it because I understood why it was limited, I was able to make peace with it

In India most of us pronounces Poisson as "poison". 😂😂😂

You're the first physics channel to tackle a very common problem with the visualization of gravity or spacetime. I hate the 2D analogy which shows the Earth or heavy object sitting on a fabric and causing a dent in it, as if gravity is pointed downwards. It's not a 2D fabric, it's a 3D scaffold/bubble centered around the heavy object, and what's happening is that space is "stretching" towards the inside of the bubble. It's harder to visualize or animate but I believe it's possible, and it will improve understanding.

Another outstanding video! I never even considered the elasticity of spacetime, so once again you have introduced an entirely new concept to me. Mind-expanding stuff. Thanks, Nick!

Very nice and easy to understand explanation of what spacetime is, I especially love the parts where you make it very clear that spacetime is not really a fabric. I would give this video 10 thumbs up if I could.

When I had found your channel that time you never raked up so many views in so less time ....way to go!

I smiled so often. And again the analogy (with its limitations) approach ... so Engineer ... and so insightful, the more angles you have to look at something, the more you develop an understanding and hooks to embed it. Keep up the wonderful work!

You are the most honest youtuber....you never tell lies

A particularly enlightening episode. Thank you. Also appreciated how you made Einstein look like he plagiarized Poisson... only to show a moment later how he actually improved Poisson by 4-D-izing and tensorizing him. But sure, even Einstein walked over the shoulders of giants. Bubbles bursted? I can't think of any but refined knowledge indeed, notably the low elasticity of space-time. Next chapter I hope for is about the QFT fields and how elastic they are in comparison.

The most simple explanation i can give you, and please someone correct me if I'm wrong, is that a time curvature is the one responsible for you to fall, you reach the ground because your future is there, which is what we call gravity. It looks like a movement in space, but that's mostly our perspective, for the universe the object is almost staying in the same "space", but moving into the future.

On the bursting of bubbles, you actually gave me the knowledge to understand in part why warp speed travel would need such things as Negative massed matter.

@BryTee

I also noticed that at 7:05 it was mentioned that an assumption that the particles in the object were moving slow compared to light. And I thought ... oh no, what happens to object moving closer to light speed. Does the space-time fabric act differently given the same mass?!?! Meaning a change in gravity as you start to get really moving (like warp speeds). That's going to complicate everything (like it isn't already complicated - LOL)

@palladin9479

3 жыл бұрын

@@BryTee I'm late I know but to partially answer your question, energy and mass are fundamentally the same thing which is what one of Einsteins equations states. All mater in motion has relativistic mass which is mass added to the rest mass based on it's speed relative to C, in ordinary mater this is an incredibly small value. As mater approaches C this changes and velocity starts becoming converted into relativistic mass, and mass warps time and thus creates gravity.

"So how many of your bubbles did I burst today?" - A LOT!!! :)
