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

The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...

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.

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where ...

The International Space Station is humanity’s most expensive gym membership. Since the earliest days of human spaceflight, it’s been understood that longer trips away from Earth’s gravity can have a ...
