Why Does Time Run Faster Upstairs? Einstein's Strange Discovery

What if time moves faster just a few floors above you? Two identical atomic clocks. One building. Different heights. After one year, the clock upstairs has experienced slightly more time than the clock downstairs. This isn't science fiction. It's Einstein's general relativity — and scientists have measured it using extraordinarily precise atomic clocks. In this episode of Midnight Theory, we explore why gravity changes the passage of time, how scientists measure differences as small as billionths of a second, and why GPS satellites must account for relativity every single day. You'll discover: Why your head ages slightly faster than your feet How gravitational time dilation actually works What atomic clock experiments revealed Why GPS satellites need Einstein's equations What happens to time near extreme gravity *Chapters* 00:00 Two Clocks, One Building 00:46 The Two-Clock Experiment 02:30 What a Clock Actually Measures 04:04 Gravity and Gravitational Potential 05:34 Why the Higher Clock Ticks Faster 07:56 Running the Numbers 09:54 How Do You Measure a Billionth of a Second? 11:46 Real Clocks at Real Heights 14:37 Why GPS Needs Relativity 17:20 Gravity Versus Motion 19:26 Does Anyone Feel It? 20:25 When Gravity Gets Strong 22:03 Back to the Two Clocks *Scientific references* NIST, JILA, NASA, ESA, RIKEN, BIPM, and published research on atomic clocks and gravitational time dilation.
