1. At the point of singularity, when talking about the big bang, is all the matter in the universe at a literal point, and thus the sphere it forms is infinitesimal in volume, or does it all simply form a spherically-symmetric body that therefore counts as a "point mass"
2. What was the "stuff" that the very first point of singularity made out of?
3. At the point of singularity right before the very first big bang (unless you believe that it is somehow in an infinite loop) all the matter had gathered in one area. How is this possible without the matter reacting (ie, creating stars, or at higher mass, big banging) BEFORE it reached a point of singularity? Did it just "spawn" at the point of singularity?
4. I always here BB theorist talk about use "space" and "the universe" interchangeably. As I understand it, "the universe" is defined by the matter it contains, and more commonly by astral bodies, and "space" is actually the "stuff" in between matter, ie vacuum. If my understanding of the terminology is correct, then wouldn't "space" be infinite, or at least much, much larger than "the universe"? If the universe is expanding, then logically space is what the universe is expanding into. To use the common example, if one were to think of an expanding balloon as the universe, the surface of the balloon being the outer most matter, then the air, both inside and out of the balloon would be "space". Is this correct?
