How do you study something you can't see?

In this episode, Yale astronomy PhD candidate Isabel Medlock explains how astronomers use powerful computer simulations and mysterious fast radio bursts to investigate the invisible universe. We discuss the cosmic web, the search for the universe's missing matter, and how scientists can effectively "rebuild" the cosmos inside a computer to understand how it evolved over billions of years.

We also chat about life as a computational cosmologist, the importance of making science accessible, and what advice Isa would give to students hoping to pursue astrophysics themselves.
