how did universe came into existence
The beginning of the universe, the start of space, and even the initial start of time itself. Nothing we observe today existed prior to that exact moment. Further, it was something outside of time, outside of space, and outside of matter that caused all of this to come into existence.The realization that our universe started, and did not always exist, brings enormous challenges to nontheistic scientists.n this point of origin, all the mass in the universe was compressed into a single point of infinite density...smaller than a single atom. 2 Then in a cosmic explosion--the Big Bang--the universe came into being.
