Gravity has passed nearly every test physicists have thrown at it for a century. Yet on the largest scales in the universe, a small mismatch may be pointing toward a limit in Einstein’s theory. A team ...

While there is a total solar eclipse over parts of Europe, that “has no unusual impact on Earth’s gravity,” the space agency explained in a statement ...

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...

Isaac Newton formulated his theory of gravity as an action at a distance: a planet instantly feels the influence of another celestial body, no matter the distance between them. This characteristic ...

Gravity is dramatically weaker than the universe’s other fundamental forces, and physicists still do not fully understand why. One theory proposes that our visible universe is trapped inside a ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...

TWEAKING gravity cannot explain why NASA’s twin Pioneer spaceships are drifting off course as they fly across the solar system. Launched in the early 1970s, the Pioneer 10 and 11 probes are ...
