The multiverse has captured the imagination of scientists and thinkers for centuries, sparking debates in physics, philosophy, and beyond.

But is it a valid scientific theory or just science fiction?

I’ve had the pleasure of exploring this issue with the leading expert in this field, physicist and author Paul Halpern. Halpern is a professor of physics at Saint Joseph’s University and the author of eighteen popular science books, including Flashes of Creation, The Quantum Labyrinth, Einstein's Dice, Schrodinger's Cat, and Synchronicity. He is the recipient of a Guggenheim Fellowship and is a Fellow of the American Physical Society.

Halpern recently published The Allure of the Multiverse: Extra Dimensions, Other Worlds, and Parallel Universes, which tells the epic story of how science became besotted with the multiverse and the controversies that ensued. Today, we’re going to dive headfirst into this fascinating investigation!

Tune in.
