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. WebFeb 20, 2024 · 1. Black holes come in different sizes. Not all black holes will have the same force of gravity, because they’re not all the same size. There are theorized miniscule black holes the size of an atom, all the …

Web1 Answer. Even before you have a black hole, you can have a neutron star. Here, the gravitational force is enough to cause atoms to collapse, as protons absorb electrons in reverse beta decay, making the neutron star essentially a giant nucleus without protons. If you add mass beyond the maximum stable size of a neutron star, you get a neutron ... WebTime slows down in a black hole thanks to a phenomenon known as gravitational time dilation. This time dilation occurs when an immense gravitational field causes a change in the passing of time. Einstein’s theory predicts that the closer you move toward the source of this gravitational pull, the slower time will become.
WebMar 23, 2024 · The Universe didn't collapse into a black hole because of the remarkably balanced conditions under which it was born, and that might just be the most remarkable fact of all. Follow me on Twitter ... WebMar 29, 2016 · A black hole is a region of space where gravity is so strong that nothing can escape, not even light. It might be surprising to you to hear that gravity can affect light even though light has no mass. If gravity obeyed Newton's law of universal gravitation, then gravity would indeed have no effect on light.
