Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

A new theory suggests gravity could possibly be the result of entropy—which would mean everything in the universe would fall ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

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 from the ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

Albert Einstein's theory of gravity, general relativity, may not be the best recipe to describe black holes. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...
