From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

It's the reliable celestial companion that's stuck around for 4.5 billion years. But the moon is slowly drifting away from ...

Long ago, the Moon was much nearer Earth. Scientists believe a protoplanet collision created the Moon 4.5 billion years ago.

Behind every bolt and curve of this racer lies science in action. Aerodynamics, weight distribution, and friction become life-or-death factors when gravity is the engine. Guy Martin’s journey shows ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its momentum goes to the Moon. To put it another way, as the Moon's orbital momentum ...

Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in ...
