How realistic is artificial gravity in space? This video explores the physics behind the idea, why it’s so difficult to achieve, and how future technology might finally make it ...

Space travel has always hit a wall with slow speeds and massive fuel needs. Gravitic propulsion systems offer a game-changing ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have revealed ...
