You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary ...

Ever since Newton published his universal law of gravitation in 1687, anyone with a slide rule and a half decent education could calculate the force of gravity on a falling body or a planet in orbit.

Gravity is the force that keeps us grounded. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Gravity is one of the universe's fundamental forces ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

Long after the human race has vanished or evolved into something else, long after the sun has swollen into a red giant and incinerated Earth 5 billion years from now, at least one human artifact will ...

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

For decades cosmologists have wondered about the nature of dark energy, the proposed antigravitational force behind the accelerating expansion of the universe. Since the 1990s astronomers have ...

While it would be awesome for people to be able to live in space, a "weightless" environment poses some serious challenges. Humans function best on Earth’s surface, where they are affected by a ...
