A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build ...

Secondary gravity waves are ripples in the atmosphere created when primary gravity waves, like those triggered by a volcanic ...

A suitcase-sized quantum sensor could soon reveal hidden water, oil, and even underground mountains—all by tracking how atoms ...

But odd things happen in space, where gravity loses its grip on solids, liquids and gases. Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion ...

QGGPf is a gradiometer, an instrument that measures variations in Earth's gravity by comparing the acceleration at which two ...

Muscle weakening and bone loss in microgravity One of the deeper consequences of time in space is muscle weakening and bone loss due to the lack of gravity. Gravity maintains muscles contracted ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

These equations combine space and time to create space-time. Gravity is explained by these equations, which are consistent with what we see in reality. All three dimensions of space (height ...

This mission will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of ...

Thanks to the International Space Station we know quite a bit about the effects of low gravity on the human body, but NASA wants to learn more. To that end, the agency has been studying how other ...
