Scientist first formulated it from the laws of physics (namely relativity) and figured out what affect they would have on the space around them. Once they figured out what the effect would be, they looked out in space and saw the effect, thus proving black holes.
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
One controversy surrounding black holes is the "information paradox," which questions what happens to information that falls into a black hole. Another controversy revolves around the "firewall paradox," suggesting that the event horizon of a black hole may be a violent region that destroys anything crossing it. Scientists are still exploring these mysteries to deepen our understanding of black holes.
Black holes are so powerful, that if you were in one, it would stretch you apart and you would NEVER come out!!!
Black holes do not emit light, so black holes can not be seen this way. But black holes emit X-rays, but stars are not hot enough to emit X-rays. When black holes suck up stars, energy goes to the black hole, and come out as X-rays.
No, there are many black holes in space. They reside throughout the universe and come in different sizes, ranging from stellar-mass black holes to supermassive black holes found at the centers of galaxies.
Yes, black holes can emit radio waves. These radio waves can come from material accelerating near the black hole before being consumed, or from the interaction of the black hole with its surrounding environment. Studying these radio emissions can provide valuable information about the properties and behavior of black holes.
After black holes, there is not much known in terms of what comes next. Some theories suggest that black holes can evaporate over time through a process called Hawking radiation, eventually leading to their disappearance. Others speculate about the possibility of black holes merging together or transforming into different types of celestial objects. Further research is needed to better understand the fate of black holes and what may come after them.
because stars come from the blake hole
We aren't certain, because 99.9% of what we THINK we know about black holes is theoretical. But the theory says that if two black holes do come too close to each other, they will merge to form one larger one. However, if the geometry of their approach is right, it might be possible for them to orbit each other.
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole
Black holes actually come in different masses, and therefore sizes.
Not exactly - What Stephen Hawking did was to promote a rationalization for an argument that black holes and white holes have similar natures. In quantum mechanics, the black hole emits Hawking radiation, and so can come to thermal equilibrium with a gas of radiation. Since a thermal equilibrium state is time reversal invariant, Stephen Hawking argued that the time reverse of a black hole in thermal equilibrium is again a black hole in thermal equilibrium. This implies that black holes and white holes are similar objects with the same nature. However the classical consideration for white holes is that they are the reverse of black holes and theoretically support the wormhole hypothesis by pairing a black hole with a white hole.
