Black_Holes

Black Holes Black Holes: before, now and forever If the theory of their existence is true, black holes are the most influential force in the known physical universe. The majority of people are familiar with the term black hole, but only a small minority of people actually know anything about them. A black hole forms as a result of an immense star running out of fuel to burn. If a star is no longer exerting outward force, it begins to collapse under its own powerful inward gravity. A common analogy is the effect of 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). Stephen Hawking is the foremost authority on black hole phenomena and relativity. When a black hole is formed in this way, an imperceptible barrier, 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). In 1915, Albert Einstein set forth the first proposition of black holes in his “Theory of Relativity”.
