But What Is SPACE?

What is space? Is it an empty stage, a dynamical geometry or something that emerges from quantum entanglement?

Space remains one of the deepest mysteries in physics. It challenged Newton, Leibniz, and Einstein, and even today we do not fully understand its fundamental nature.

In this video, we follow the idea of space from classical physics and general relativity to the quantum vacuum, quantum gravity, holography, AdS/CFT, and emergent spacetime. Could space be continuous, discreteor not fundamental at all?

Space is where you park your car… Time is money… Spacetime is paid parking. 🖖🤖👍

I remember as a kid spontaneously coming up with the idea that space isn't a background stage at all but is just an expression of the potential for objects to interact with each other & thought I'd stumbled on something revolutionary, blissfully unaware that Leibniz had beaten me to it 300 years ago lol.

I think this is an honest and bold attempt to see things in correct perspective.

There's a lot of space in space.

Very well structured and explained. You have yourself a new subscriber.
I would be very surprised, if your channel didn't become popular - the mere fact that your script and visuals aren't A.I. should attract many viewers. That is my hope anyway.

After this video i need some space

maybe we just create a radius of space around us every moment

String Theory. Where they just throw countless dimensions and constant patches on it to keep it relevant but it still has tons of problems.

everything is space, space is everything

stunning graphics and great information

Expanding space-time will lead to the answer. :cat-orange-whistling:

Space is a property at the observation system.

So good!!!! I often wonder what the 3 dimensions plus time is. There must be a structure to reality.

Very good video. I have guesses about how graph theoretical connection might lead to spatial adjacency and temporal succession of moments. It’s fun to play around with. Graph theory in general is a fun field.
