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 ...

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 ...

Standing at the doorstep of an interstellar revolution, scientists are now nearer than ever to breaking the code of warp drives a technology that can propel human civilization throughout the galaxy at ...

Einstein's general theory of relativity, published in 1915, relates spacetime curvature to matter distribution, leading to the Schwarzschild solution describing a black hole. The Schwarzschild ...

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 ...

But come to think of it, I don't know that we can say that there's any such thing as spacetime inside a black hole. When a black hole forms from stellar core compaction, there is a huge amount of ...
