Origin of the Universe - Astronomy

Not entirely sure as to what question you're asking exactly but many theories of the origin of the universe have risen for many decades now. But as you would know, the Big Bang theory is the most accepted one. Since I'm typing this from my phone, I won't go into detail but I did once write an essay on this.
There are obviously parties that are against the theory and parties that are for it. But some of the other theories of origination sometimes fail to cover certain aspects or even suggest of multiple dimensions beyond what we already believe exists.
But none are as well researched or factual as the Big Bang theory.
Hope that helps :)
