There are lots of articles and math done on how the universe was created. Almost all of these focus on how matter was created, along with lots of effort on describing and unifying the 4 known forces.

But the really difficult and fundamental question to me is, "How was space created? " Assume you want to create the universe and have to start someplace, where do you start, by building the box, or building the contents?

Does anyone know of any theoretical work on how space would have been created, what energy would it take, and speculation on where it would come from?

The idea I am thinking of is if you imagine that the whole universe had only 1 cubic meter of space to contain all the matter, there would have been no effective gravity or black holes problem because there would be a total uniformity of force, all particles would not experience any net gravity from any direction. Then if you create space in this solid volume of mass, the mass is not really expanding, as much as space is being created such that it appears that the mass is blowing up when in reality it is space that is increasing giving the apparent effect that every particle is moving away from each other.

The galaxies are still in movement away from each other, would that be explainable and consistent if space was still being created at a constent rate uniformly throught the universe? How would we be able to detect the difference?
