There was no Big Bang
The Universe did not start with the Big Bang. It did not have a beginning, nor will it ever end. It has been present forever, says a study which has formulated an equation. The most prevalent theory of origin of universe says it all began 13.8 billion years ago when everything was condensed in an infinitesimally small point, or singularity, and exploded and expanded. Mathematical calculations and Einstein's Theory of General Relativity explain the Big Bang and what happened after it, but they do not explain singularity or what happened before it. The new study claims to have prepared a model which suggests that singularity did not exist and gives the universe an infinite age
