🪐 In 1971, the astronauts of Apollo 15 left a small aluminum device called a retroreflector on the surface of the Moon, which allows scientists to precisely measure distance by bouncing laser beams from Earth. Over decades, these experiments have shown that time passes ever so slightly faster for the reflector on the Moon than for clocks on Earth, due to weaker lunar gravity—a subtle, real-world example of gravitational time dilation across the solar system. ✨ #timedilation⚡#moon⚡#apollo⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
