I'll start off my idea;
A singularity is when a star collapes and a blackhole is created. Everything is sucked into that blackhole, matter, light, time, even space itself. Its unknown whether or not anything can come back out of a blackhole, but scientists speculate that it can't. An easy way to put a singularity is 'everything into nothing'.
Now what happens when you reverse that process? 'Nothing into everything'. Basiclly, thats the reverse of a singularity, where time, matter, space and everything comes back out.
But what caused this 'big bang'?
Nobody really knows yet, we can only speculate to how the universe was formed. The best I can say is that the fundamental field in nature is the gravitational field, and out of this and its weird quantum properties, the stage was somehow set for everything else we can identify in the physical world including time and space. We do not, however, understand what the gravitational field 'is' in any real fundamental way. We know how it operates but that is not exactly the same as understanding its actual nature. Physicists who are investigating String Theory are trying to understand what gravity is, but we will have to wait for them to give us some concrete predictions we can go out and test to confirm if their ideas are on the mark or not.
