Videos of astronauts on the Moon show them often bouncing across the lunar surface, helped by the fact that the gravity of our satellite is just one-sixth of Earth’s surface gravity. That experience ...

While most people assume their height remains constant, science shows that due to gravity, humans can become 1–2 centimeters shorter by the end of the day. But in space, the effect is far more ...
