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

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

Here’s how it works. General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the ...

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

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

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 physicists ...

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

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

General relativity, once an exotic description of gravity, is now a powerful research tool. The quest to grasp gravity began long before Einstein. During the plague that ravaged Europe from 1665 ...

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

Furthermore, because gravitational interactions are weak, more precision is needed to study true quantum gravity effects beyond general relativity, which is a classical theory. "A quantum theory ...
