In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

An artist's concept of twisted space-time around Earth. Albert Einstein's theory of general relativity is a monumental achievement of human ingenuity, creativity and perseverance — to say the least.

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

More than 100 years after Albert Einstein published his iconic general theory of relativity, it is beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in ...

Finally, scientists have their finger on the pulse. Spinning dead stars, known as pulsars, blast powerful beams of radio waves into space. As a pulsar spins, its beams sweep past Earth, producing a ...

How much of a role did Albert Einstein's first wife play in the theory of relativity? In recent years, some historians have asserted that Einstein shared the credit for his research on the special ...
