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 ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

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 ...

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

A new look at da Vinci's papers reveals his insightful attempts to probe the nature of gravity 500 years ago. Engineers from Caltech have discovered that Leonardo da Vinci's understanding of gravity - ...

The secret to directly detecting dark matter might be blowin’ in the wind. The mysterious substance continues to elude scientists even though it outweighs visible matter in the universe by about 8 to ...

Antimatter — the mysterious substance that's the mirror opposite of matter in most ways — falls downward in gravity like everything else in the universe, a team of physicists reported Wednesday in the ...

It’s official: Antimatter falls down, not up. In a first-of-its-kind experiment, scientists dropped antihydrogen atoms and watched them fall, showing that gravity attracts antimatter toward Earth, ...

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...

Visitors to 'gravity hills' worldwide witness cars seemingly rolling uphill, sparking myths of supernatural forces. However, these locations are masterful optical illusions. The surrounding landscape ...
