Web2 okt. 2024 · However, if you built a machine to throw the ball fast enough (roughly 25,000 miles per hour) then it would overcome the Earth’s gravity and escape forever. Now imagine compacting the mass of the Earth into the size of a thimble. That is the point where the speed to escape becomes the speed of light. WebBlack holes are a fascinating phenomenon in the universe. The mass inside a black hole is so compact that it swallows everything up and nothing can escape from it. Not even light can escape. It therefore does not travel in straight lines and is strongly distorted. We know what a black hole looks like thanks to an image from April 2024: a dark ...
