What happens when a lifelong skeptic, a science communicator, and an astrophysicist sees something in the sky he can’t explain?

In this episode, we step back from the eerie and the unexplainable… and zoom all the way out. To galaxies, black holes, and the limits of what we think we know.

We talk with Ethan Siegel about the moment that shook his worldview—and what it really means to stay grounded in science while keeping your mind open to the unknown.

Whether you're here for the mystery or the math… this one will rewire your brain.
