Black holes and gravity
WebBlack holes are invisible spots in the galaxy where gravity pulls in all matter and light, according to NASA. Even though black holes are invisible, scientists can find them because they can study how stars near them behave differently. WebA black hole is an extremely dense object whose gravity is so strong that nothing, not even light, can escape it. Every object in space has an 'escape velocity': the minimum speed at which something must move to escape the object's gravitational field. On the surface of Earth, the escape velocity is about 11 kilometres per second, meaning that ...
