Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of ...

GALVESTON, Texas — When the Apollo 11 crew got back from the moon 40 years ago this week, they showed no ill effects from seven days spent in weightlessness. But as American astronauts and Soviet ...

Undated -- Imagine being onboard that first human expedition to Mars. Representing all of humankind you take your historical one small step, one giant leap onto the surface, only to find your legs ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Matter and antimatter behave the same way under the influence of gravity, a new study found, leaving scientists no wiser as to what makes the two different. Antimatter is the puzzling stuff created ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...
