What Happened Before The Big Bang
Everyone knows that the answer to the question of how the universe came to be is the Big Bang but the Big Bang theory only scientifically proves the situation after the Big Bang but many theoretical physicists predict in their books this Big Bang theory. However,it is in a way based on Einstein's general theory of relativity.But before that we need to talk a little bit about a mistake made by einstein in the days when there was no Big Bang theory. What this means is that when the field equations proposed by Einstein were applied to this universe,he observed that the universe would expand or contract. But in the old days it was believed that the universe was permanent without moving.so,Einstein thought that even these field equations when applied to the universe should be constant. To this end he introduced a new cosmological constant in his equations.The universe becomes balanced when it is used.But later Edwin Hubble's res
