Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

As one star spins another out of view for the next century and a half, astronomers use it to weight an incredible binary system. Share on Facebook (opens in a new window) Share on X (opens in a new ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...

The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast ...

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

Disclaimer: I am very much a physics noob. This might be a nonsensical question. That spacetime can be curved or warped is something I can grasp, but I keep getting stuck on one specific aspect of how ...

When you travel through the Universe, it isn't just a free ride through empty space. Although you might not think about it very often, there are forces arising from the presence of everything else, ...

A paper appeared in Classical and Quantum Gravity. Co-author, Associate Professor of the Department of Relativity Theory and Gravity of KFU Alexei Zayats explains, "Light is distributed linearly in ...
