Why do astronauts age a little slower in space? This short video breaks down Einstein’s relativity in the simplest way possible. When astronauts travel at high speed and experience weaker gravity, time moves slightly slower for them compared to us on Earth. It’s one of the most mind-blowing facts in modern physics. Watch until the end for the easiest explanation of time dilation you’ll ever hear. #NASA #Astronaut #ScienceShorts #Universe #SpaceFacts
