Black holes are regions in space with such strong gravitational pull that nothing, including light, can escape from them. They are formed when a massive star dies and its core collapses under its own gravity.
Black holes cannot be directly observed since they do not emit any light, but their presence can be inferred through their effects on surrounding matter and light. Scientists use telescopes and other instruments to detect the gravitational pull and radiation emitted by black holes.
If two black holes were to collide, they would merge into one larger black hole. This event would release an enormous amount of energy in the form of gravitational waves and could also create a burst of X-rays and gamma rays.
No, black holes cannot destroy the entire universe. While black holes have strong gravitational pull, they are not infinitely powerful. They can only affect objects within their immediate vicinity and do not pose a threat to the entire universe.
It is highly unlikely for a person to be sucked into a black hole. The gravitational pull of a black hole would have to be incredibly strong and the person would have to be very close to the black hole for this to happen. Additionally, the intense radiation and tidal forces near a black hole would likely kill a person before they even reached the event horizon.
