Astronauts Age Slower in Space — Here's Why You'd Never Notice

Right now, astronauts aboard the International Space Station are aging slower than you are. Not by much—only 0.007 seconds over six months—but measurably, verifiably slower. Yet if you asked them, time feels completely normal. Extended Description (After "Show More"): This is the strange reality of time dilation: time genuinely runs at different rates depending on your motion and location in a gravitational field, but you never feel it because everything about you—your perception, your thoughts, your awareness of duration—slows down proportionally. Einstein discovered this over a century ago, and every test since has confirmed it. GPS satellites must account for time dilation or navigation fails. Particle accelerators observe it constantly. Your head ages faster than your feet by about 90 nanoseconds over your lifetime because it's slightly farther from Earth's center of gravity. In this sleep documentary, we explore: Why time is relative, not absolute, and what that means for reality The twin paradox and what happens when you travel near light speed How black holes stretch time to infinity (from the outside) The philosophical implications: does the future already exist? What "now" means when simultaneity is observer-dependent How accepting time's strange nature can bring peace to your experience This is physics that sounds like philosophy, science that questions the nature of existence, and knowledge that helps you sleep by dissolving your grip on something you never controlled: time itself. Perfect for falling asleep to—calm narration, deep concepts, gentle pacing. Let time dilation carry you into unconsciousness as we explore the most fundamental dimension of existence: time, which is far stranger than you ever imagined. #TimeDilation #Relativity #SleepScience #Einstein #Philosophy #Spacetime #Physics
