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

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.

Elephants may never fly, but they may have quite a load off their feet in some far distant day. Though scientists generally assume that gravitation is as unchanging as any of nature’s absolute laws, ...

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...

Heading into space means leaving Earth's gravity behind. Astronauts floating around on the International Space Station might look like they're having fun in the weightless environment, but a lack of ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

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 ...

Gravity is tough. It took Newton a long time to crack it and a lot of Newtonian physicists a hundred years to confirm Einstein’s gravitational theories. And that’s the naturally occurring stuff.
