Did the universe really start with the Big Bang? What if another universe existed before it?
I was wondering, did the universe really start with the Big Bang? What if another universe existed before it?
The prevailing theory among scientists is that the universe did indeed begin with the Big Bang, but there are other theories out there. As for whether another universe existed before this one, it's certainly possible. The concept of a multiverse suggests that there may be an infinite number of universes, each with their own set of physical laws and properties.
