Can gravity cause a black hole
WebMay 28, 2024 · Plumbing black holes for knowledge of quantum gravity originated with Stephen Hawking. In 1974, the British physicist calculated that quantum jitter at the surfaces of black holes cause them to evaporate, slowly shrinking as they radiate heat. Black hole evaporation has informed quantum gravity research ever since. WebAug 3, 2015 · That energy-saving transition should inevitably cause the vacuum to collapse and wipe out the universe. ... The black hole's gravity can shift the energy balance, Moss explains, so that any bubble beyond a certain very small size could instead lower its energy by growing. Within a fraction of a second, the bubble would then expand to consume ...

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 ...
