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 ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

A substance called antimatter is at the heart of one of the greatest mysteries of the universe. We know that every particle has an antimatter companion that is virtually identical to itself, but with ...

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.
