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 ...

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.

Spiral galaxies rotate at such a high speed that the gravity calculated only from their visible stars could not prevent them from dispersing. To solve this puzzle, physicists have postulated ...

Gravity is a basic force that affects everything we experience. Watch as a flat earther attempts to explain it without using ...

Since conventional explanations have failed to pony up dark matter, one physicist is looking towards the unconventional. In a series of two papers, physicist Stefano Profumo of the University of ...

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 ...

Gravity seems constant but it turns out, Earth is weirder than that. Gravity actually wobbles a bit across the planet. And ...

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...

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 ...
