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

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

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

Black holes are mysterious cosmic objects with gravity which are so strong that even light cannot escape. They form when massive stars collapse under their own gravity creating a dense point called a ...
