Last week, the Japanese meteorological satellite Himawari-8 snapped a pretty cool image of Australia from space. The image shows an enormous gravity wave sweeping through the atmosphere off the ...
Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks and planets in orbit. A growing group of physicists is now treating that ...
Hi, everyone, I'm Mwaksy. I'm Greg.Quick question, Greg. Yes. So, I know if I let drop this apple,it will fall because of gravity. Yes.Ooh! Good catch.But what exactly is gravity? Gravity is a force ...
General relativity has never been tested in places where the effects of gravity become truly extreme—for example, at the edge of a black hole. That will soon change Scientists have been trying ...
