Many people think that black holes are a kind of dark place and vacuum place. It's not like that at all. Black holes are that body Whose destination and mass are very high. Gravitational force is very high in it. black holes are available in the galaxy. How do black holes form? If we talk about how black holes are formed. When any stars whose mass is more than Earth. When such stars are killed, then the same stars become black holes. This process is not a small process, it takes millions of years. Now some questions have arisen that how stars form and break? Every cloud filled with dust and gas mixed in the galaxy, which we call a Nebula. Most of these clouds contain hydrogen and then about 20-30 percent helium. Some percentages are slightly different gases. All the materials of Nebula are mixed with each other with the help of Gravitational. Then slowly it attracts all the materials to itself. We call it Prostar. Slowly, due to pressure and heat, there would be fusion of hydrogen. He then becomes a star. In which the density, mass and gravitational forces of that level are very high. , , bit.ly/3ihoC9v
