For centuries, we have observed the night sky and wondered about the laws of nature, matter, and our place in the universe.

Once rooted in theology and philosophy, these questions are now being explored through the prism of high-energy particle physics with one goal in mind - to discover the final, definitive theory - the theory of everything. But what is a theory of everything? And does it even exist?

Here today, to explore these questions with me, is none other than Don Lincoln, a renowned experimental physicist and host of the Fermilab YouTube channel! Don has recently published Einstein's Unfinished Dream, a book in which he explores the cutting-edge research of modern particle physicists that is slowly pushing us towards a theory of everything.

Tune in!
