Black Hole

Black holes are some of the most fascinating and mysterious parts of space. It has so much gravitational pull that nothing can escape from it, even light if it gets close enough. Albert Einstein predicted black holes back in 1916. The term “black hole” was made up in 1967 by an American astronomer John Wheeler. The first black hole was discovered in 1971 by rockets that were carrying Geiger counters that came across eight new x-ray sources. Scientists that detected radio signals coming from it found the black hole calling it Cygnus X-1. There are three types: stellar black holes. Intermediate black holes and supermassive black holes. When a large star burns through the last of its fuel, it will collapse and fall creating a small stellar black hole. It has the mass of the sun into a city-size range, which creates an insane amount of gravitational force pulling everything inside of it. The dust and gas from the galaxy makes black holes grow. If you thought that was big, the supermassive black holes are millions or billions of times as massive as the sun. These are thought to be in the center of every galaxy like the Milky Way. Scientists aren’t too sure about how such large black holes spawn. They think they might’ve spawned from hundreds or thousands of tiny black holes that came together into one. Intermediate black holes are the middle size black holes. They form when stars that are together in a cluster collide in a back to back reaction. It is possible that these mid-size black holes can fall together in the center of a galaxy and form a supermassive one. Black holes have three layers-the outer and inner event horizon and the singularity. The event horizon is the boundary around the front of the black hole where light loses its ability to escape. Once something passes the event horizon, it’s trapped and can’t leave because of the strong gravitational pull. The inner region of a black hole is where its mass is, also known as its singularity which is
