Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

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 ...

In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very ...

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 ...

(Nanowerk News) 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 ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...
