If the universe came from a single atom, then

In summary, according to the current model, the universe began with the big bang and the observable universe was once as small as an atom. However, this does not necessarily mean that the entire universe was once an atom or that atoms have the potential to spawn more universes. The origins of the universe are still a complex and widely debated topic.

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.
 

1. What is the "single atom" theory of the universe's origin?

The "single atom" theory, also known as the Big Bang theory, proposes that the universe began as a singularity - a single point of infinite density and temperature - and rapidly expanded about 13.8 billion years ago.

2. How does the "single atom" theory explain the formation of the universe?

The theory suggests that the singularity underwent a rapid expansion, known as inflation, which created space, time, and matter. As the universe cooled, particles began to form, eventually leading to the formation of stars, galaxies, and other structures we see today.

3. Is there evidence to support the "single atom" theory?

Yes, there is a substantial amount of evidence that supports the Big Bang theory. This includes the observation of the cosmic microwave background radiation, the abundance of light elements, and the large-scale structure of the universe.

4. What existed before the "single atom" or Big Bang?

It is currently unknown what existed before the Big Bang. Some theories suggest that there may have been another universe or a multiverse, while others propose that time and space did not exist before the Big Bang.

5. How does the "single atom" theory relate to the creation of life on Earth?

The Big Bang theory explains the origin and evolution of the universe, but it does not specifically address the creation of life on Earth. However, the expansion of the universe and the formation of stars and planets provided the conditions necessary for life to develop on our planet.
