Hey! Have you ever seen movies about black holes where ships go into a
black hole and come out somewhere else? This is science fiction, but black
holes are real. Here's the true story of black holes. A black hole is a theoretical concept in the process of gravitation. The gravitational field of a black hole is an extremely dense body so strong that nothing, including electromagnetic radiation (which includes visible light) can escape it . A black hole is region of space. The name comes from the fact that electromagnetic radiation or light is unable to escape, which makes the inside invisible. However, black holes can be detected if they interact with matter outside of them. For example, by drawing in gas from an orbiting star. The gravity pulls in the gas, heating up to very high temperatures and emitting large amounts of radiation in the process. This helps scientists to see where blackholes are located. So now you see that black holes are real objects in space. As time passes and technology gets better, more and more mysteries about black holes can be solved. Here are some neat links that will give you more information about black holes:
