Black+holes

​ Black holes Black holes comes from the biggest stars that supernova. These holes have so much gravity that when it pulls everything in, nothing can escape, not even light. Astonauts can't see black holes but they can detect them. Our sun is an ordinary normal sized star. It wouldn't turn into a black hole or a neutron star. A neutron star is a star that has supernova turning into neutron star. Only a star two times the mass of the sun can do that. A neutron star weighs so much. It even weighs more than the sun. A tablespoon of neutron star would weigh about two trillion trillion trillion trillon tonns. Black holes are stars that are three times the mass of the sun. When a star supernovas, the core would collapes beyond a neutron star turning it into a black hole. Supermassive black holes might be located in the centre of every galaxy.
