From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

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 ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot ...

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 ...

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 ...

According to Einstein’s Theory of Relativity, space and time are inextricably connected. In our Universe, whose curvature is barely measurable, the structure of this spacetime is fixed. In a ...

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 ...

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 ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...
