Hey guys, According to most pop science sources, "before" the Universe started to exist, there were no time, which can be understand easily as time is only possible if there are at least two existing object (e.g. two quarks, two atoms, etc.). Time as I understand it is a measurement of movement, and motion is relative. But when it comes to space, I can't imagine there is no space "before" the Universe started to exist, I also can't imagine that space has some kind of geometry (e.g. closed topology, finite but unbounded, etc.). If the Universe indeed shaped like a sphere, finite but unbounded, then the "space" inside it can be described as the volume of the Universe. If I'm going to describe a "space" with closed geometry, it is not actually space but a really large spherical object with massive volume and given that it is something with size, then it is always be finite and limited despite a composite object within this spherical object known as Universe keep passing its starting point. Can someone explain these without using mathematics, in a way that someone can understand it much easier?
