Gravity

The test chamber will enable scientists to test technologies and structures on Earth before sending them to the moon.

The waves allow for vital glimpses of objects that don't produce much light.

Physicists turned on a new type of gravitational-wave sensor and saw two intriguing results, but they aren't yet ready to claim a discovery.

Certain weird gravity conditions would make it possible to travel through a wormhole and back.

Here's why the force of gravity pulls us down rather than up. The answer involves Einstein and the bendy realm of space-time.

Scientists have used computer models to predict the size of minuscule deformations, or mountains, on the surfaces of neutron stars, which are responsible for causing gravitational waves as they spin.

The experiment could be a trial for many more even smaller ones probing the long-kept secrets of quantum scale gravity.

Astrophysicists have a wild idea to explain the bizarre abundance of super-high-energy radiation shooting from the center of our galaxy: gravity portals.

Bumblebee gravity could explain dark energy — if it's proven true.
