The first planned artificial gravity experiment took place in late 1966, but the first human on the Moon beat them to it.

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 ...

According to legend, Galileo dropped weights off the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...

Though spacecraft with artificial gravity are still a distant dream, we had proof of concept way back in September 1966.

Engineers from Caltech have discovered that Leonardo da Vinci's understanding of gravity—though not wholly accurate—was centuries ahead of his time. In an article published in the journal Leonardo, ...

Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...

A team of engineers studying the 500-year-old, backward writings of Leonardo da Vinci have found evidence that the Italian polymath was working out gravity a century before its foundations were ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

The triangle ain't equilateral. Also, I read the jar drawing as being constant speed, not constant acceleration. Each consecutive falling object is at a constant horizontal distance. At the small ...
