On their way to a colony planet around Proxima Centauri b, roughly 4.2 light years from Earth, the crew of the Ark One suffers a species-threatening catastrophe while still a year away from their ...

As Earthlings, most of us don’t spend a lot of extra time thinking about the gravity on our home planet. Instead, we go about our days only occasionally dropping things or tripping over furniture but ...

Astronomers suggest that an alternative concept of gravity, known as modified Newtonian dynamics, could explain orbital inconsistencies that have previously pointed to the existence of a ninth planet ...

Could data pointing toward a mysterious planet at the edge of the solar system actually suggest it's time to revisit our theory of gravity? When you purchase through links on our site, we may earn an ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets. A team of NASA ...

As the story goes, mathematician Sir Isaac Newton was sitting in an orchard after supper when he saw an apple fall from a tree. He wondered why apples always fall straight to the ground, instead of ...

There are several ways that surface gravity on Earth could change. We wouldn’t like most of them. If a mini black hole collided with Earth and didn’t pass straight through, it would sink to the planet ...

A 'gravity hole' on Earth? Earlier this summer, researchers with the Indian Institute of Science published a paper exploring one of these 'gravity holes'. Found all over the planet, these are spots on ...
