New theories suggest the speed of light isn’t just a number, but evidence that reality itself is curved. What looks like a ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Want to call someone a quick-thinker? The easiest cliché for doing so is calling her a computer – in fact, “computers” was ...

Einstein’s famous equation states that energy (E) equals mass (m) times the speed of light squared (c 2); the speed of light (c) is a universal physical constant exactly equal to 299,792,458 meters ...

Simple, child-like curiosity taught us at a young age, that if we push an object, it will move. If we push harder, it will move faster and remain in motion longer. Clearly though, there are both ...

Nothing can travel faster than light. But what if we switched the rules a little? Imagine a world where the speed of light ...

One of Einstein's most famous fundamental laws is that nothing in the Universe can travel faster than the speed of light in a vacuum. If you're a massless particle, you must travel at that speed, and ...

The principle of relativity, as initially described by Galileo, posits that the laws of physics remain consistent regardless of an observer's relative motion. Einstein's special relativity ...
