Our universe has long been considered the only one(Thus the name universe). However new studies in the world of astrophysics says that there are probably more. Maybe even an infinite number! However, none of these universes are exactly the same as another. That's because of 2 things:probability and quantum mechanics.
Scientists have argued on whether the universes are in groups, individual spots over an infinite spacetime continum. Some scientists say parallel universes are in groups called multi-verses. Multi-verses are large spheres made up of many spherical universes. However each one as differences with another. Some scientists even say that every universe has its own laws of physics. That means what's possible here might be impossible there, and vice versa. That is all I have to say for now on parallel universes.

Have you ever heard of the string theory?

theoretical physicists have been going on about this for a while although i didnt think there was any evidence for it yet. linky?

Speaking as a (diillusioned ex-)physicist, I have to say that 'spherical' is not a word that should be used to describe these universes.

It's worth noting that our ability to conceptualise the universe(s) is only as advanced as our understanding of physics and mathematics. Quantum theory is a method of explaining experimental data based on a certain level of mathematical ability. It, like all scientific theories, is an approximation of the truth. The goal of science is to narrow and refine these approximations as far as possible.

And now that my brain is protesting fer chris'sakes it's four in the afternoon an' y've made me stare at feckin' tax returns fer over six hours and now ya make me try and think about PHYSICS, ya basturt?!, I'll humbly take my leave.

I recall a certain Phillip Pullman writing something about this, not just in his books but a artical on his website, I'll see if I can find it.

Fred Alan Wolf wrote a good book on this subject called............What else?Parallel universes.
