“
There can be no such thing as nothing.
”
Why?
First, it is observed as such by QM, but that is just a fact, and not a ‘why’, so, the best we can say at this point is that this is the default law in the land of no laws, for cause-and-effect has reached its end, there necessarily then being no cause or ‘’why’ before to speak of. We still like to say things, though, so we could say that the simplest state must be perfectly unstable, for we note the trend that the simpler and simpler readily combines and/or goes through phase changes. In fact, even way up at the molecule level, molecules are neither inclined to react nor not react, yet the simpler stuff, aside from the inert, usually does.
“
Thus this happens everywhere, so we have infinity.
”
Your "thus" doesn't actually follow.
Well, at least everywhere that QM looks, which is anywhere, so we extend.
“
As it must ever happen, we have eternity.
”
Doesn't follow.
We extend to this since we always observe it, and because laws here have been noted to be the same ‘way out there’, such as when we predicted many neutrinos coming from supernovas far away, using science developed here.
“
Here, then, the buck stops, for ‘nothing’ is the root that cannot be or stay as such.
”
That's self-contradictory. On one hand you claim it cannot be and on the the other you're saying that it can be but isn't stable.
It can’t be, even for an instant, but it must still be the basis since the basis cannot just be yet another ‘something’.
“
Existence must adhere to the balance of opposites
”
Why? What "balance of opposites"?
Pair production of positive and negative charge, matter and antimatter, always paired.
“
which is the prime candidate for why there must be conservation of energy and momentum.
”
How?
All must ever sum to this balance of opposites: nothing, or at least to the near nothing of quantum uncertainty.
“
‘Nothing’, by virtue of not being able to occur anywhere, is the infinite, eternal, causeless, prime mover, and necessarily the only one possible to meet the criteria of infinite and eternal.
”
If "nothing" cannot exist then how can it be the "prime mover"?
Because it cannot exist, everything must then move. Movement, not stillness, turns out to be the natural state of affairs. Perhaps there is no absolute reference point for absolute stillness (I know, just free thought.)
It probably would take a God to hold nothingness intact, but there we have run out of outside influences and forces, so it is not restricted. Possibility reigns, requiring not anything before, for that would only be more possibility. This is the only way the downward chain can end, for there cannot be infinite regress, which is the sure doom of other theories.
