Black Holes Explained – From Birth to Death

Black holes are perhaps the most abnormal thing in presence. They have no meaning. Where do they come from … and what happens if you fall into one? The stars are an incredibly large collection of mostly hydrogen atoms that collapsed under their own gravity from a massive gas cloud. At their core, nuclear fusion crushes hydrogen atoms into helium, releasing a tremendous amount of energy. This vitality, as radiation, pushes against gravity, keeping up a fragile harmony between the two forces. As long as fusion occurs in the core, a star remains stable enough. But the way our own sun’s heat and pressure on the core for stars with more mass allows them to fuse heavier elements until they reach iron. Unlike all the earlier elements, the fusion process that produces iron produces no energy. Iron is formed at the center of the star until it reaches a critical volume and the balance between radiation and gravity is suddenly broken.
