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 ...

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 ...

An illustration of heavily curved spacetime, outside the event horizon of a black hole. As you get closer and closer to the mass's location, space becomes more severely curved, eventually leading to a ...

Chawla, A. (2026) On the Black Hole Information Loss Paradox under a Novel Phenomenological Model of Quantum Measurements.

In a hypertorus model of the Universe, motion in a straight line will return you to your original location, even in an uncurved (flat) spacetime. The Universe could also be closed and positively ...

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 ...
