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 ...

Even if it turns out that time loops never take shape, studying them provides key insights into the deepest rules of reality.

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 ...

For the first time, astronomers have directly observed a spinning black hole bending space and time, as predicted in Albert ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

Time runs faster on Mars (477 microseconds/day) due to relativity. Discover how this fundamental physics challenge requires dynamic correction to prevent massive GPS errors and secure future deep ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and feasting on its stellar material. The observation is ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy lifting was more challenging than I initially thought." When you purchase ...
