What did Newton understand that was such a revolution? Can someone just... explain gravity to me? Let's start with a ...

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

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.

Unfortunately, these theories don't complement one another. General relativity, which describes how gravity works, implies a smooth and flowing universe of warps and curves in the fabric of spacetime.

But in new work accepted for publication in the journal Astronomy & Astrophysics, astronomers propose something much, much simpler: gravity. Just gravity. Breaking space news, the latest updates ...

This global water pressure works against Earth's gravity to form two bulges: the high tides. "The ocean isn't being lifted or stretched," Perez-Giz says. "The ocean is bulging along the Earth-moon ...

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

Einstein's theory of general relativity is the best description of how gravity works. Ghez and her team collected data at the W.M. Keck Observatory in Hawaii.

Here, we'll dive into how these beds work, if they're worth the money, and who should (and shouldn’t) buy one. In the zero gravity position, your body is placed at a 120-degree angle ...
