Is there any proof that it's conceivable that there may be a multiverse? I think so- photons are not things, they are fields and, using Heisenberg laws, we are allowed to quantify as a physical object- an object with MASS. So if you stare into an atom and it's photonic cloud you are in theory able to "take a snapshot" of that orbiting photon in one place as one object with mass. I assert that subatomic elements exist in more than one Universe- that explans how they're able to go from A to Z in two Planck movements instead of 26, as they do. And on a different note- what is the possibility that someone will cut a piece of paper and accidentally slice an atom in half and trigger an atomic explosion???
The short answer? None. The long answer is that there are several reasons why this is impossible. One, the "sharp" edge of a pair of scissors is actually several hundred to thousand atoms wide so it would be impossible to "slice" an atom. When scientists say that they "split" and atom, what they are talking about is fission which is when a neutron hits the nucleus of an atom, splitting it into several different atoms, and releasing energy and more neutrons in the process. Secondly, the electron shells of atoms repel against one another to the point that it would take an explosion the force to atoms together. The other reason why it is impossible is because atoms above atomic number 26 can be split but atoms below atomic number 26 fuse. This means that the hydrogen, carbon and oxygen atoms of the paper are too small to split. They could fuse, but that takes the energy of at least, an atomic bomb. The iron in the scissors is even worse. Iron is atomic number 26 which means it cannot fuse or split. So there you go. I hope I answered your question sufficiently.
Other than some very high level math I wouldn't even try to comprehend, I believe the main rational for the multi-verse theory, is that it could explain why the edge of our universe is accelerating. Basically it is the same idea of how galaxies, or stars interact by pulling on each other, but in this case the pulling effect is speeding up the rate our universe is expanding. I believe Hawking's recent theories on black holes, and how the birth of every black hole could be a new universe may also have some connection to the theory. Basically the idea is that the big bang is what the inside of a black hole looked like after supernova. As to your last question, I believe the answer is yes, in the same sense that you could walk through a wall. While it is statistically possible, the likelihood of its occurrence is basically nonexistent.
Come on guys- this is the Golden Age of Cosmology... there has to be an inference of a multiverse or altiverse. You guys are telling me that physics is still a closed science constrained to our universe?
Apologies for being offtopic, and I should say I'm no professional physicist so I probably have nothing useful to add - but would "proof that it's conceivable" be useful at all? I don't know if the maths behind it adds up, or even if there is any maths behind it, or if in this example it would ever even be possible to have some maths behind it. But even if it did, I think the best we could hope for at this stage is proof that it COULD be possible, and is that actually useful at all? Not that there's anything wrong with learning for the sake of it, of course.
I'm not a scientist but I'll give you the best explanation I can. If one accepts the big bang theory, then one must also explain other physical phenomena. We can observe that the universe is expanding and doing so at an ever increasing rate. Theoretically, the expansion should be slowing because of the effects of gravity. But it isn't. There are a couple of logical suggestions one could make about why this is so. One is that the universe continues to expand at an increasing rate because the initial momentum of the big bang continues to overcome gravity. My understanding is that this doesn't make sense to physicists. They believe that, at or near the perimeter of the universe, gravity should be overcoming the 14 billion year old momentum. The other suggestion is the multiverse. It suggests that there are other universes and their gravity is attracting the extremities of our universe. Scientists like this suggestion because it is consistent with the accepted laws of gravity. It isn't an observable or measurable phenomenon, of course. It is a suggestion on what might cause an observed phenomenon that seems to fly in the face of current physical thought. Personally, I think it is as good as any other suggestion and it certainly doesn't fail the logic test. There is no logical reason to think our universe is the only one. Perhaps one day they'll figure it out with finality.

The multiverse is nothing more than metaphysics posing as physics. Physicists ran out of explanations and made something up. Its an egotistical joke and should turn any atheist into at least an agnostic. Hawking is a (*)(*)(*)(*)ing Hacking! 'Oh I was only wrong in this universe. But in another universe I was right'. Its the kind of argument you would expect from a 5 year old. The emperor has no clothes.
