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.

NASA Responds to Claim That Earth Will Lose Gravity in 2026 ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

Cooling metal bars to near absolute zero, suspending microscopic gold beads, or searching for signs that gravity might be quantum: meet the scientists hunting for gravity's elusive nature ...

If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all know that don't we? It's actually not true — and an attempt at a massive ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot explain. The dominant answer has been dark matter, an unseen substance ...

Geologists have long been captivated by the Indian Ocean's "gravity hole," where the Earth's gravitational pull weakens, its mass falls, and sea levels drop by about 328 feet (100 meters). After years ...

Stanley Deser, a theoretical physicist who helped illuminate the details of gravity and how it shapes the space-time fabric of the universe, died April 21 in Pasadena, California. He was 92. His death ...
