How big must a star be to form a black hole
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 ...
