Orbital data reveals that rocks transforming deep inside the Earth may be responsible for changes to our planet’s ...

On March 17, 2002, the German-US satellite duo GRACE (Gravity Recovery and Climate Experiment) were launched to map the global gravitational field with unprecedented precision. After all, the mission ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with quantum mechanics. Physicists Mikko Partanen and Jukka Tulkki at Aalto ...

The Indian Ocean "gravity hole" is the site of the deepest dent in Earth's gravitational field. It's a circular ocean region with a gravitational pull that's so weak, sea levels are 348 feet (106 ...

The halls of science, known for prim propriety and careful debate, are feuding. A new theory of gravity challenges Einstein's general relativity, our current understanding of that thing that keeps our ...

Deep below the Earth's crust, molten rock rises and falls, driving the movement of tectonic plates on our planet's surface — and for some time, researchers have debated whether the moon also has a ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.
