A black hole is an object that is so massive that nothing, not even light, can escape the pull of its gravity. We do not know what is inside of them because they trap light. Then they cannot be observed directly.
A black hole is a region of space in which the gravitational field is so powerful that nothing can escape after having fallen past the event horizon. The name comes from the fact that even light is unable to escape. However, black holes can be detected if they interact with matter outside the event horizon, for example by drawing in gas from an orbiting star. The gas spirals inward, heating up to very high temperatures and emitting large amounts of radiation in the process.
A black hole is an object in space, more like a region, where the gravitational pull is so powerfull that nothing can escape after that object has passed a certain point. It is called a black hole because nothing, not even light can escape its pull. It cannot be observed directly, and we have no idea what is really inside of them.
A black hole is an object in space that is so massive that nothing can escape the pull it has, not even light. The only way we can study or look at them is by looking at some particles that may be moving around the hole at high speeds emitting large amounts of radiation.
A black hole is a region in space that nothing that is in its gravtiational realm can escape. The gravitational pull from a black hole is so great it even pulls in light. And also nothing can ever be observed after entering a black hole. We haven't observed them directly because we would have been sucked in. We just have seen gases being sucked in and causing radiation. So we don't know what is inside if anything.
Black holes are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun.Their gravity is so strong that not even light can escape it. Black holes can be detected if they interact with matter outside the event horizon. For example by drawing in gas from an orbiting star, the gas spirals inward, heating up to very high temperatures and emitting large amounts of radiation in the process.
