The popular theory of the Big Bang implies that the universe is expanding and will either continue to expand, or will begin to contract into the Big Crunch. But a few decades ago, there was yet another theory about the nature of our universe, The Static Universe. In the Static Universe theory, all of the galaxies, stars, planets, and particles are in a perfect gravitational equilibrium, where the maxim 'one for all and all for one' really exists. This is so because every single body in the Static universe would be responsible for everything else. Any fluctuation in the positioning of any celestial body would result in chaos. The reason why this chaos would occur is simple. If every single galaxy, star, planet and other celestial bodies were static that means the gravitational pull would be exactly the same everywhere. If any fluctuation in the positioning of anything did occur, then a fluctuation in the gravity would occur as well. The equilibrium would be broken, because the gravitational pull would be unequal, and most if not all of the galaxies, stars, and planets would collide thus creating a total catastrophe. This Static theory has suffered many setbacks, such as the discovery of the red and blue shift of stars, and the theory of the big bang. The Big Bang Theory has several advantages to it. The incredible speeds at which everything is receding away from everything else is great enough to overcome most gravitational forces in the universe, except Black Holes (using the Anthropic Principle, if this were not true, then it would not exist today). The Big Bang Theory is also supported by the calculations of Albert Einstein. Yet, he did not wish to believe in this theory and introduced a special medium into his mathematics to create a Static Universe. He later said that it was the greatest mistake of his career. So at this point, most physicists agree that an expanding, not static, universe exists today, all starting from the Big Bang.
