If the universe came from a single atom, then

If the universe came from a single atom, then...

The current model says the universe came from the big bang, the original point being something as small as an atom, and this atom expanded into the size of the universe in which we see now.

If this is true, then wouldn't it mean every atom in the universe has the potential to spawn more universes, so in theory, there could be hundreds and hundreds of trillions of universes that could just "spawn" at any time, just like how the original big bang was formed?

Strictly speaking, the current model says that the region of space which now corresponds to the observable universe was once as small as an atom.

Note in particular:

• This does not say that the universe was once an atom. The very hot and dense conditions of the early universe does not mean it was a particle of some kind.
• This says nothing in particular about the entire universe beyond the observable region. The very hot and dense region from which the observable universe has since expanded was part of a larger (infinite?) region, similarly hot and dense, which goes beyond the observable universe.

So the short answer is, no; this does not mean atoms can spawn more universes.

BB is widely regarded as invalid when pushed to the point of singularity - not unlike speculating human beings originate from biological singularities. I suspect the origins of the universe are similarily more complicated.
