Scientists propose a groundbreaking experiment using quantum computers and atomic clocks to test whether gravity alters the ...

Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency ...

A test using atomic clocks will watch superpositions ride Earth’s curved space-time and see if Einstein can play nice with ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

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

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research ...

ABSTRACT: Aims: The expansion of the Universe and gravitation are considered different fundamental properties of the cosmos. We explore whether they are connected and propose an equation that links ...

Avi Loeb explores how experimental quantum gravity approaches may one day help to connect the dots between quantum mechanics and general relativity.
