Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like ...

A star’s fatal brush with a supermassive black hole can light up a quiet galaxy. When gravity shreds the star, its gas ...

A supermassive black hole was caught twisting spacetime, offering the clearest real-world evidence yet for Einstein’s ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

The cosmos has served up a gift for a group of scientists who have been searching for one of the most elusive phenomena in ...

An artist’s impression depicts the accretion disk surrounding a black hole, in which the inner region of the disk wobbles. In this context, the wobble refers to the orbit of material surrounding the ...

Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date.

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

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 ...
