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 ...

In many graphics about gravity, the spacetime geometry is visualized ... This theory has features that could explain both dark energy and dark matter, the unknown and hypothetical components ...

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 ...

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 ...

So our motivation was to come up with a more feasible experiment that would have the power to at least falsify that gravity is classical," explained Serhii Kryhin, a third-year graduate student at ...

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 ...
