An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift ...

Here on Earth, we take gravity so for granted that it took an apple falling from a tree to trigger Isaac Newton's theory of gravitation. But gravity, which draws objects together in proportion to ...

Researchers have found that bone and muscle mass are regulated by the altered gravity. The experiments were done in space using Kibo, an ISS module developed by JAXA, and on the ground. An ...
