We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Time moves differently in space. Near black holes, gravity slows clocks and stretches seconds. This explainer reveals how time bends and affects astronauts and Earth.

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

When a star gets too close to a black hole, the gravity of the black hole changes what happens next in really big ways. They give us a chance to see how strong gravity affects the star and the space ...

Now things get tricky because what a lot of popular science articles tend to leave out is that, according to Relativity, it isn't just speed that affects time, so does gravity. The closer you are to ...

Time isn’t this fixed universal thing that works the same everywhere, and Mars is a brilliant example of how location in space actually affects how fast time passes. A clock on Mars would literally ...
