this is why I gave up on TV and watch YouTube instead. Thank you for posting this!

He gave this entire lecture in a single breath... amazing

Amazing talk and amazing attitude. This is the ethic and spirit true physicists bring in. Top of the line.

This should go viral and taught in schools. Thank you so much for this video.

I love watching Nima. I don't have a clue what he's talking about but his energy has filled me with enthusiasm for The End of Spacetime.

David Bohm and Jiddu Krishnamurti already talked about time being simply a perceived phenomenon while time in actuality eludes out of reality, stretches and dissipates. They also concluded that we don't even have the linguistic means to grasp this concept through the vocabulary available. Their series of discussion is called The Ending of Time.

Amazing stuff.

Physicists must never abandon the scientific method: experimental verification of all theories.

The AI suggested this, the comments made me watch, and I loved it, simply revolutionary and brilliant.

[rustybolts]

A very "magical" lecture, thank you all very much.

[danimal]

Wow! What a badass, and his language to explain this all is so understandable... there's a lot to be said about those who can explain complex things simply.
Definitely found my next rabbit hole!

[claudelebel]

Space and time are concepts and no concept can capture reality. Concepts may be helpful at describing certain phenomena but ultimately they always limit and fall short.

Thank you so much for posting this lecture with the graphics. Now I understand it better. 👍👍👍

Thanks for exploring the bounds of the known world, and props to you for explaining it in a way plebs like me can follow. Good luck! I'll be cheering you on from the side of the field.

[TGMResearch]

Great talk, and a line of thinking way more promising than much speculative stuff that's going around.

[Darkmatter]

Amazing talk by an amazing person. Thank you for this

The leap that needs to happen is letting go of particles and growup enough to stop smashing things together hoping to find meaning in the pieces.

"In any system of energy, Control is what consumes energy the most.
No energy store holds enough energy to extract an amount of energy equal to the total energy it stores.
No system of energy can deliver sum useful energy in excess of the total energy put into constructing it.
This universal truth applies to all systems.
Energy, like time, flows from past to future".

The Amplituhedron sounds *a lot* like Wolfram's Physics project (branchial space, the ruliad)... simple combinatoric graphs leading to emergent QM and spacetime physics.

Oh boy oh boy! What a fantastic talk this and I can tell you I have watched a lot of similar looking and sounding talks on the notion of space time etc this is by far the best I’ve come across. Well done professor am I look forward to further interesting outcomes from the research and thought experiments you all are doing! Interesting times ahead
