The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

We're framing it as a fight, man.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

Oh, no, I see.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

More like, again, this is the type of thing of...

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

Why do we believe that the laws have to be coming from the same thing?

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

I think that that's a pretty bold and fun assumption.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

And you can imagine that if somebody thought that at every different energy scale, just there's some new things, because that's the way it is, that you couldn't predict, that's a very different vibe than thinking that there's a mathematical consistency or some underlying principles that will carve out a space of theories that still can be consistent with observations.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

So what I view it as is, again,

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

As a hep theorist, we're making this bet about the structure of these laws of nature that probably has some consequences that you wouldn't be able to see when you're just in the nitty-grit of it.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

And that excites me a lot, thinking of, OK, if I could zoom out and see the structure of the corpus and which theories are actually consistent with each other, wouldn't that be fun?

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

And so I think I like that because that feels closer to the kinds of things that excited me about physics as a kid.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

Now, it's still further away from a lot of like there's some companies now that are trying to do like AI for physics with a thing of like we're going to like, you know, like robots are going to come out of the physics thing.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

It's like I don't.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

I it's probably not physics the way I define it when that's the case but there is cool like you can unlock cool things when like you're changing the way you're doing things and I think that I sorry for good for this quantum gravity thing it's again it's about trying to condense this corpus you're trying to like find a single description that can limit to two different things and right now we really have only a limited number of suggestions like roughly string theory is a framework

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

Can you try to find other ones?

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

You probably never would if you're just sociologically in a field where everything you're learning is in the context of like within string theory.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

It probably would be some variant of it at any point, just almost by accident.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

So I think it's kind of fun to do a little bit of a meta layer and think about like what are we actually after as a field and be clear about those goals.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

Oh, I love it.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

So Perimeter is founded by Mike Lazaridis.

The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe

He's one of the co-founders of BlackBerry.
