Zero gravity, often depicted in science fiction and space documentaries, is a fascinating concept that sparks curiosity and ...
Drag (air resistance) opposes acceleration due to gravity. In a vacuum, such as on the Moon, both objects will hit the ground at the same time. How does gravity work?
A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...
If gravity reversed on the sun, McCluskey said he’d be scared because it is the only thing keeping the sun together. Nuclear fusion, inside the sun, pushes outward. Without gravity, the sun would ...
Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 ...

With a planned capacity of 1,900 g-t (gravity acceleration multiplied by tonnes), it will outclass existing facilities, including the U.S. Army Corps’ hypergravity machine with its 1,200 g-t ...
