These contain millions to billions... WebOct 29, 2024 · According to Einstein’s general theory of relativity, the gravity of a black hole is so intense that nothing can escape it. The more sophisticated understanding of black holes developed by Stephen Hawking and his colleagues in the 1970s did not question this principle.
Why do black holes have such intense gravity?
WebAug 29, 2024 · Nothing is darker than a black hole. A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held … WebJul 31, 2024 · 2 Answers Sorted by: 31 They don't. The gravitational field is the same outside all spherical objects with a given mass. But a black hole is much much smaller than a star with the same mass, so you have access to regions much closer to the center, where the gravitational field is stronger. jmam e ラーニングライブラリ study.jp

WebSep 23, 2024 · Black holes can be defined as the most compact objects we know of. That is, a lot of mass is concentrated in a very small volume (such as a sphere). Imagine now that you are sitting on Earth's surface and that, without moving in space, you replace planet Earth with a black hole that has the same mass. The black hole will be very small. WebA black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it!
