Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

Astronomers have seen spacetime itself wobble near a spinning black hole for the first time. The discovery, revealed during a star’s destruction, confirms a major prediction of Einstein’s theory of ...

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline. This ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...
