Astronomers have finally watched a black hole do something Albert Einstein only described on paper, twisting the fabric of ...

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

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 ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

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 ...

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 ...

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

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...
