In this episode, we break down Einstein’s mind-bending theory of relativity and explore how it affects something as everyday as your phone. You’ll learn why time doesn’t tick the same for everyone, how speed and gravity can mess with your clock, and why your GPS wouldn’t work without Einstein’s equations.
