You are wrong, scientists have admitted that parallel universes do exist, they just deny they are spiritual heavenly universes.

Except that they can't know that for sure so they have no basis on which to make that claim.

They know based on their assumptions that they aren’t!

Except that they can't know that for sure so they have no basis on which to make that claim.

Actually they have proof from our knowledge of atoms. Inside the article is a few paragraphs that speak to this. Their belief of other universes comes from the knowledge that there is space between the protons and electrons.

If you could enlarge the proton of a hydrogen atom to the size of a baseball, the electron of that atom would be about the size of a BB rotating around the proton ten miles away at the speed of 10,000 miles a second. Now if the earth were a proton and the moon an electron and the space between them had the same ratio that exists in a hydrogen atom, the moon would be 1,000 times farther away than it is now. I know, it can be a bit difficult to wrap your brain around it.

So, knowing that all this space exists in an atom, many experts in the field of atomic energy have come to the conclusion that it is theoretically possible for parallel worlds to coexist at the same time in the same space, both passing through the other, unaware of the each other’s existence.

So very true, dear sister in Christ!
