I do theoretical particle physics. We're trying to understand the most basic structure of matter. And the way you do that is you have to look at really small distances. And to get to small distances, you need high energies.

We have this very clean picture of science, you know, these well-established rules with which we make predictions. But when you're really doing science, when you're doing research, you're at the edge of what we know.

You have principles. You test them as accurately as you can. Eventually, they might break down.
