You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot explain. The dominant answer has been dark matter, an unseen substance ...

Physics is filled with mysteries – and, believe it or not, gravity remains one of them. We rely on gravity to explain things large and small. But at a fundamental level, we still don’t fully ...

An ancient spear-throwing tool enabled prehistoric hunters to boost the distance they could launch a feathered projectile – but the unexpected negative effects of gravity on the tool may explain why ...

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...
