Summary

Ever wondered why your brain invents pain, how a simple arch in your foot changes the way you walk, or what would happen if you were caught near colliding black holes? Welcome to The Rest Is Science, where hosts Hannah Fry and Michael Stevens turn the mundane, the mysterious, and the downright bizarre into a masterclass of curiosity. Each episode is a deep dive into the fabric of our reality, blending rigorous physics and biology with the kind of playful experimentation that makes complex topics feel instantly accessible. Whether they are testing the limits of a twenty-five-year-old space pen, debating the ethics of neurotechnology and privacy, or unraveling the history behind a three-million-year-old stone, Hannah and Michael act as your guides to the hidden mechanics of the world around us. What makes this show truly stand out is its relentless focus on the "why" and "how." The hosts don’t just deliver facts; they challenge long-standing scientific dogmas and encourage you to question how your own senses construct your personal reality. It is a show for the intellectually restless—a perfect mix of high-level scientific exploration and lighthearted, human-centered inquiry.
