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

If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all know that don't we? It's actually not true — and an attempt at a ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...

When teachers explain ocean tides, they frequently describe how the moon's gravity pulls on Earth and all of its water. This, they often say, leads to a gravitational imbalance, which stretches ...

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 ...

Other scientists think the effects of dark matter could be explained by fundamentally modifying our theories of gravity. According to such ideas, there are multiple forms of gravity, and the large ...

is in theory destined for spaghettification thanks to a sharp increase in the strength of gravity as you fall into the black hole. Black Holes, explained As astrophysicist Neil Degrasse Tyson once ...

The snow in Interior Alaska also contains a lot of air, so gravity doesn’t pull on it ... the snow and the wire or fencepost. Sturm also explained a unique quality of snow that causes trails ...
