Though it is very difficult to imagine infinity but we have to admit that our universe is infinite. We cannot escape by saying that it is finite simply because if it is so then the question will arise as “What’s there after the finite boundary?” Now, as it is not finite, there must not be any starting point or finishing line. In other words, it cannot have any origin or deathbed. This is the hurdle, Big Bang a hypothetical theory is likely to face. In order to theorize the origin of the universe, it propagates willy-nilly a starting point the Bang a starting point of space and time! But does not this theory thus limit the Infinite?
Perhaps, it is better to view our evolution and journey as unlimited and ascending. Sri Aurobindo said, “There is an ascending evolution in nature which goes from the stone to the plant, from the plant to the animal, from animal to man. Because man is, for the moment, the last rung at the summit of the ascending evolution; he considers himself as the final stage in this ascension and believes there can be nothing on earth superior to him. In that he is mistaken.” This mistake is nothing but to believe that we have reached the end point of evolution. It is perhaps same sort of mistake to theorize about a starting point or a “Bang” origin.
