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 ...

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 ...

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, ...

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 ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

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 ...

Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...

Antimatter has intrigued and confounded physicists for almost a century, and the effect of gravity on antimatter has been a point of disagreement. New research may have settled the debate by finding ...

Isaac Newton's historic work on gravity was apparently inspired by watching an apple fall to the ground from a tree. But what about an "anti-apple" made of antimatter, would it fall in the same way if ...

The Juno spacecraft now orbiting Jupiter has a suite of science instruments which will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the ...
