Why You Age SLOWER on the Moon: Top Astrophysicist Explains | Avi Loeb

14 Dec 2025 #TimeDilation #AviLoeb #MoonScience
Why you age slower on the Moon: Harvard astrophysicist Prof. Avi Loeb breaks down the fascinating physics behind time dilation in lower gravity. Discover how Einstein’s general relativity predicts that time literally runs slower in weaker gravitational fields—like on the lunar surface compared to Earth. In this episode, Loeb explains the real measurable difference in aging between an astronaut on the Moon and someone staying on Earth, why GPS satellites already prove this effect daily, and what it means for future lunar bases and long-term space travel.

We dive into the twin paradox thought experiment, the difference between special and general relativistic effects, and why the Moon’s 1/6th gravity creates a tiny but real clock-slowing phenomenon. Loeb also touches on cutting-edge research about gravity’s role in biological aging and whether living in reduced gravity could subtly affect human lifespan.
Perfect for anyone curious about space, relativity, or the science of time itself. If you enjoy clear explanations of mind-bending physics from one of the world’s top astrophysicists, subscribe for more.
