Black Holes Black Holes: Infinity and Beyond If theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms as a result of a massive star running out of fuel to burn (Chaisson, 193). Once the star is no longer exerting outward force by burning off gases, it begins to collapse under it’s own intense, inward gravity (Chaisson, 193). It is like slowly letting the air out of a balloon. Once the star is compacted to a certain size, while it’s mass, or weight, remains the same, it’s gravity becomes so powerful that nothing can escape it (Hawking, 87). This critical size to weight ratio is known as the Schwarzchild Radius (Hawking, 87). Once a black hole is created in this way, an invisible area, or line around it exists. If any object crosses this line, it can no longer escape the gravitational force of the black hole (Hawking, 87). This line is called the event horizon (Hawking, 87). If black holes are proven to exist, beyond theoretical physics, then they would probably be a very common anomaly in this universe.
