Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the ...

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...

Falling into a black hole means facing extreme stretching, known as spaghettification, due to immense tidal forces. While ...

One way to longer life may be higher gravity—at least for rats. That is the “very tentative suggestion” of experiments performed by NASA Physiologist Jiro Oyama, who has been raising mice and rats ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

Researchers are 3D printing human muscle in zero gravity to create better disease models and improve astronaut health during space missions.
