Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

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

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible ...

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

In 1998, a gentleman by the name of John Titor arrived from the future, or so he said. In his timeline, as he claimed, ...

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 ...

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 ...

When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But ...

"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 ...

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 ...

Based on Einstein's theory, they demonstrated that if a massive object rotates rapidly, it drags space-time along with it.
