The story of Isaac Newton's life. He discovered gravity, and the laws of motion that underpin much of modern physics. Yet he ...

Our understanding of the universe may be completely wrong.

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

This wasn't some sudden lightning bolt of inspiration. Newton spent years developing his ideas about gravity, working through mathematical proofs and observations. The apple was merely the beginning ...

Einstein's Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation of how the universe ticks. But there are some holes ...
