Could a reactionless, gravity-defying propulsion system actually work? A former NASA engineer says yes, but scientists are ...

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

Scientists have long sought the particle that carries the force of gravity, but a new theoretical model tosses out that idea entirely – and shows how it could be tested in experiments ...

For over half a century, scientists suspected a quiet but powerful electric field might be influencing Earth’s upper ...

Professor Claudia de Rham from Imperial College London explains the basics of gravity, while we discover the best place on earth to weight ourselves, with Professor Paddy Regan from Surrey University ...

Kurt Hinterbichler reviews Claudia de Rham's first-hand and personal glimpse into the life of a theoretical physicist and the ...

NASA’s AWE mission just released millions of gravity wave images from space, unveiling atmospheric forces that ripple through ...

It is at the core of General Relativity, which treats gravity as a curve in spacetime rather than a fundamental force. But plenty of quantum gravity theories predict a deviation from this equivale ...
