Though spacecraft with artificial gravity are still a distant dream, we had proof of concept way back in September 1966.

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Are we living in “The Matrix” in real life? In the 1999 science-fiction film, Neo discovers that the universe is a simulation — but one scientist believes that the idea isn’t all fiction. Dr. Melvin ...

WASHINGTON, May 14 (Reuters) - An exhaustive examination of lunar gravity using data obtained by two NASA robotic spacecraft is offering new clues about why the two sides of the moon - the one ...

Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects from floating skyward. For humans, it’s a leash that stops us from ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...
