In this episode, friend of the show and astrophysicist Professor Geraint Lewis returns to help me wrap my head around one of the strangest ideas in modern physics: Time Crystals.

After stumbling across a Nature article that left my brain pleasantly scrambled, I called up Geraint for a deep-dive into what time crystals are and why physicists are so excited about them. We explore why Time Crystals don't have real-world applications yet, but how they could open entirely new frontiers in future technology.
