For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

Albert Einstein's theory of general relativity is based on the idea that massive objects cause a distortion in space-time, which is felt as gravity ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder ...

A researcher throws cold water on a recent effort that purported to eliminate black holes' greatest and most enduring mystery ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable.. This is the conclusion of ...

Quantum gravity research aims to merge general relativity and quantum mechanics, potentially reshaping our understanding of ...

Einstein’s theory of general relativity sees gravity as the curvature or warping of spacetime by an object, with more massive objects having a greater effect on the spacetime surrounding them.

A new theory from a University of Alaska Fairbanks scientist suggests a bold idea: that time—not space—might be the true ...

The Theory of Relativity, Then and Now Albert Einstein’s breakthrough from a century ago was out of this world. Now it seems surprisingly down-to-earth ...

New mathematical work provides a way to identify when information has been changed by manipulating space-time – and it may ...
