I agree there must have been something "like that". But there are still some serious gaps:

1. the theory begins with "everything" in an unified form. Then the "everything" already existed at the time.
2. when "nothing" is created why should a kaboom occur? can't they just be an "everything" and a "nothing" peacefully side-by-side? I don't quite understand this: "The materialization then gets into conflict with... materialization itself"
3. why would the explosion occur radially around a center? who invented 3D space and linear motion anyway?

Therefore for a big-bang explosion to happen you need a number of things: matter (the sutff that actually pops), some forces which rule that matter cannot stay pressed together, and some space around. And since all these things had to exist just before the bigbang, there are two options:
1. they were created just before the explosion
2. they were around for longer

And if space, matter and fundamental forces were already there at the time of the boom then I believe the following theory is more plausible:

The idea that the big-bang did not actually create the universe, but is just a local phenomenon, doesn't seem to be very popular for some reason. I posted it somewhere on this site already, but here it is again: what if the big-bang is just one of many others like it out there, and there's nothing special about it, is just like a big star, keeps sucking matter until it pops, matter flies all over until inertia wears out and gravity pulls everything back.

I'm not talking about a pulsating universe, but about a "local phenomenon", meaning there are other balls of matter out there which follow the same pattern. We can barely see the margins of our big ball, and we'd have to squint really hard to see further.

The pea-size ball, right before it exploded, is then plausible. I believe that particular size has something to do with Planck scale times all known matter in the universe (at least what we can see).

It all adds up: the REAL universe is infinite and time did not suddenly begin some billion years ago. But at the same time we're back to square one: everything adds up but nothing is explained.

By the way, do you happen to have a theory about what space is? At least some vague ideas; nobody comes even close to trying to explain it. And, quite literally, nothing moves without it. It is most likely an illusion created as the side effect of some rule, but why 3 dimensions? I have a hunch it can be approached by studying numbers, more dimensions may appear out of necessity, like in the case of complex numbers. There's your second dimension, it appears out of nowhere as a consequence of the properties of numbers. But the darn complex numbers seem to be self sufficient, there is no hint of a second imaginary number.
