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 ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

Is gravity a result of differences in informational density? Or is this theory too far out there to address all the issues present in modern physics? Here, we take a look at a recent proposal that ...

Gravity's impact on bone cells—experiments heading to the International Space Station Mechanical engineers at the University of Michigan are tackling mysteries of bone density loss in space and on ...

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 ...

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 ...

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 ...
