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 ...

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 ...

Caltech engineer Mory Gharib was poring over the digitized notebooks of Leonardo da Vinci one day, looking for sketches of flow visualization to share with his graduate students for inspiration.

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 ...

Physicists at CERN have discovered that antimatter falls down. Sure, it sounds like an obvious thing, but scientists haven’t yet been able to confirm that it responds to gravity in exactly the same ...

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, ...

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 ...

Dark energy — a mysterious force pushing the universe apart at an ever-increasing rate — was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle ...
