Absolutely... modernized String Theory and simple observations of entropy back up the possibility of the universal origin.
Several Quantum Theories, String Theory in particular, hypothesize the existence of more than three dimensions (with String, more than 10 different dimensions).
On a different note, Entropy, or as it is more commonly known -disorder in the universe -always wants to decrease. This is why gravity condenses things, large complex molecules spontaneously break, and atoms fuse in dense and hot conditions.
By those rules, the zero dimension contains no room for anything to move. There is no length, no width, and no height. Even in non-existence, zero dimensions is unstable. So, similarly to an unstable bomb exploding, the dimensions "unfolded" from the zero dimension and from them, a single 10-dimensional string was cut and replicate itself trillions of trillions of times to form wave-particles.
Also, I wanted to note that infinity and nothing are complete opposites. Nothing, no dimensions, no nothing... means that even the vacuum doesn't span forever, in fact, it means that the vacuum doesn't extend at all. What I think you mean is that there is an infinite amount of empty space. I don't know what you meant about the atoms/math thing though.
