According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

Is Einstein's General Theory of Relativity the work of a lone genius, as myth would have it? Yes and no.

1 General relativity and quantum mechanics finally put everyone’s minds at ease by showing that the action wasn’t actually at a distance after all.

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

According to general relativity, you would first cross something called the event horizon, the outer edge of the black hole, beyond which not even light can escape. Then as you continued falling, the ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...

Using gravitational waves to approximate pi, physicists see no problem with Einstein's theory of general relativity.

Albert Einstein's theory of general relativity has held up pretty well after a century out in the world.
