Do you mean that the Universe always existed, or that there is a multiverse/cosmos/bouncing universe beyond our Universe?
The real problem with discussion of prerequisites is that they don’t solve any big bang mystery.
As has been said, there are a lot of contenders for that including ‘there was nothing’ - including no prerequisites.
I suspect we will never have any idea because all the experiments we can perform use existing ‘prerequisites’
I truly was not looking for a debate. And it is far more productive to a discussion to post your own personal belief and support it - rather than to simply discredit other persons offerings.
what would be needed to allow a singularty of immense energy and density to exist?
"What was before the Big Bang?"
So what do we KNOW would be needed to make a Big Bang?
what would be needed to allow a singularty of immense energy and density to exist?Time
The potential for a Big Bang requires that mathmatics either always existed, or came into existence at the time of the Big Bang.
I would love read more from andreasva that elaborates on the existence of TIME prior to the Big Bang.
So let's start there - what would be needed to allow a singularty of immense energy and density to exist?
We don't really know.

OK, in that case this is best moved to new theories which gives scope for a full description of your hypothesis.
We don't really know.Apart from anything else, whatever it was didn't happen in this Universe.So we don't know what the laws of physics which the "prerequisite" would have to obey.
Like I said, be careful what you wish for...
hy even consider that different laws of physics could even exist? We have never seen any. Let's assume that the laws of physics we have are multi-universal until proven otherwise.
The universe we inhabit did not always exist, but the preconditions required to allow it to exist had to already be in place.
That means that there was "SOMETHING" before the Big Bang. Some condition existed that allowed sub-atomic particles to pop into existence, vanish, then appear in a different place (as per quantum physics). So even though space time and the fabric of space we occupy did not exist before the Big Bang (other instances may have preceded our universe), SOMETHING existed that allowed the possibility for a universe to spawn. Most likely what existed was a condition of reality that worked by some set of laws, using some combination of mathematics, string theory, and quantum mechanics to make it possible for all that exists now to exist. The key point is that there was always SOMETHING.
