Your theory was a little hard to grasp at first but after thinking about it I think it makes a lot of sense. Since on Earth we can`t comprehend all 4 dimensions of space, it only makes sense that the universe and space itself would be part of that larger dimension and would be completely beyond the understanding of any human. Kind of like a 4-dimensional sphere. I think that theory makes more sense than any I`ve heard so far. Thanks for sharing it.
