troduction: Have you ever thought about what happens to something after it gets pulled into a black hole? Or have you ever wondered where black holes come from? A couple of years ago I read a book about the stars, it was supposed to teach me how to go outside and find the constellations in the night sky. While the book was describing the locations of the constellations it talked a lot about how the stars were formed. It also talked about the galaxies that were surrounding and beyond those stars. I have not been able to stop reading about it since. So today I am going to walk you step-by-step through the creation of a black hole, in hopes of giving you a better understanding of what a black hole is. Body: In a book titled “Universe” , Dinwiddie defines a black hole as a region of space containing, at its center, some…show more content…

Eventually this star becomes so large that the nuclear reaction in the core of the star, pushing out, is no longer sufficient enough to counteract the enormous force of gravity that is pushing inward, and the star begins to undergo gravitational collapse. When this takes place, they refer to the star as having gone Supernova. Part IV. In the Supernova stage the star is collapsing into itself. Much the same way that an ice-skater will spin faster as she tucks her arms and legs in against her body, as the star is collapsing into itself; it begins to spin faster and faster. This gives us the most luminous light show known to man. Where the star may have been spinning on its axis 37 times a year as a Red Super-Giant, it is now spinning 37 times a minute. This creates enormous amounts of heat and energy, until eventually the energy become so great that the gravity is no longer strong enough to contain it and the star explodes into space. Part
