How do scientists find out about black holes
WebNov 13, 2015 · A black hole, as you probably know, is comprised of a singularity, where if we define the black hole on an x-y-z plane, is a vertical limit approaching negative infinity on the z-axis. The point theoretically exists at the end of this theoretical, snow-cone-like shape, and is the source of the immense gravitational pull that black holes are so ... WebBlack holes grow by consuming matter, a process scientists call accretion, and by merging with other black holes. A stellar-mass black hole paired with a star may pull gas from it, and a supermassive black hole does the same from stars that stray too close. The gas settles into a hot, bright, rapidly spinning disk.

WebBlack Hole. A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is ... WebMost famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the …
WebAug 21, 2024 · A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. WebAug 21, 2024 · Scientists can study stars to find out if they are flying around, or orbiting, a black hole. When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light. Could a Black Hole Destroy Earth?
