Like you want to send things in at higher energy so they get close enough and then you can start to see the structure of the thing.

#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
So imagine like you have like this bag of quarks and you start to see that like the kind of component nature of your β
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
like protons and things like that.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
So it's just, you're colliding and then you're trying to measure what's coming out and you want to like try to infer how your theory of the interactions is consistent with that.

I'm sorry, I mean, so, I mean, it should be jets at some point, these things, I'm sorry.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
So like basically you're colliding
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
say, depending on the collider, you're putting, say, electron, positron, and other colliders, and this is, say, two protons are colliding.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
And you're going to have the protons are made up of some quarks, and then they're going to have some interactions, and then they're shooting out other quarks.

#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
But there's other particles in your standard model field theory.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
And those interactions will determine, I guess, the rate at which different things are produced.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
And so there's a theoretical thing.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
You're modeling those very short distance scale interactions.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
And then you're trying to infer from the energy deposited or different particle tracks that this thing is actually what happened to then say something about your theory.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
That's fun and that's cool.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
But the scary thing is just how big, how hard it is to probe those high energy scales.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
And you see these huge, I mean, the collider itself is like, these rings are amazingly huge.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
Yeah.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
I mean, well, they're near a border, but yeah.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
Yeah, so very interesting engineering feats for fundamental physics.
The Shawn Ryan Show
#312 Sabrina Pasterski - Theoretical Physicist on the Hidden Code of the Universe
And that's cool and something I probably didn't appreciate as much because I went into theory.
