For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

Time travel is deterministic and locally free, a paper says —resolving an age-old paradox. This follows research observing ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...

A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.
