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 ...

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 ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

How then does a neutron star radiate into space even in the absence of anything to replenish the radiance? One of the solutions is a strange counterintuitive effect of contemporary physics that empty ...

Researchers have measured gravity using the effects of time dilation. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Breaking space news, the ...

The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle ...

In a laboratory experiment, researchers have succeeded in realizing an effective spacetime that can be manipulated. In their research on ultracold quantum gases, they were able to simulate an entire ...

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 ...
