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 ...

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

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

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 ...

In general relativity, the localisation of gravitational energy is obscured by the equivalence principle, leading to a variety of pseudotensorial prescriptions. Teleparallel gravity, an ...

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 ...

However, Newton's theory of gravity could not explain certain observations, such as the precession of the perihelion of Mercury. In the early 20th century, Albert Einstein developed the theory of ...

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 ...
