Could reality be made of more dimensions than those we perceive? The question has consumed some of the most brilliant physics ...

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 from ...

Twin black hole collisions detected in 2024 have provided the sharpest-ever test of Einstein’s theory while revealing new details about how black holes form and spin.

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Cosmic strings, high-energy remnants of the early Universe, may unlock time travel by warping space-time. These ...

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory suggested that gravity could bend light by curving the fabric of spacetime. To ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of cosmic collisions. The twin discoveries, labeled GW241011 and GW241110, ...

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.
