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

Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the theory of general relativity, revealing how mass and energy bend the fabric ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

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

Teleparallel gravity, an alternative gravitational theory that emphasises torsion over curvature, offers a framework in which energy and momentum may be defined in a more transparent manner.

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

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

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

The Physics of Gravity: Einstein vs. Quantum Gravity General relativity describes gravity as spacetime curvature but conflicts with quantum mechanics at black hole singularities. Loop quantum gravity ...

In the early 20th century, Albert Einstein developed the theory of general relativity, which provided a new understanding of gravity. According to general relativity, gravity is not a force in the ...
