The James Webb space telescope had several stunning findings this year that changed how we understand the universe.

For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes.

To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange ...
