Nima Arkani-Hamed - What are the Ultimate Questions of Nature?

What are the most fundamental questions, the most penetrating questions, that we can ask of the natural world? Stretch your mind. Envision all manner of things, whether in the 'heavens' or on the Earth. What might be the ultimate theories of a future physics?

I love physics, the only problem is, I do not understand the math behind it!

[jamesruscheinski]

Is there a relationship of physics to mathematics? For instance, could physics emerge from mathematics?

[FigmentHF]

I feel like we are in a very obvious “the sun obviously goes around the earth, moment” I wonder what it is?

Nima needs to come out and be part of the debate, what are the tictacs seen in 2004 get in there for fawk sake.

Does the quantum have something to do with time?

[shirleymason]

So: imagine a time when life in our Universe is SO advanced that those on the edge of our visual distance will see across their visual distance and record, returning to us what we are missing. And so on, and visa versa. There could be entire networks swapping data.

Error of expected v observed vacuum energy being 120 orders of magnitude? I seem to remember a film where Leonard Susskind quoted the very same figure as the chances of the "fine tuning" of the rate of expansion of the universe being within a suitable band for a habitable universe. Forgive my ignorance of physics, but this coincidence seems noteworthy. Surely?

[wagfinpis]

Morality the great advantage in his investigation!

I think when a star goes supernova and creates new elements, that's what happened at the big bang except it created new laws.. Now ask me what other laws could be created, and I start feeling like this guy

It's so hard to listen to people who say um ah aha um every other word.

I love the series, but this dude is a programed,
