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

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

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 ...

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 ...

Scientists say fragments of energy may be the fundamental building blocks of the universe—not particles and waves.

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 ...

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

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 ...
