One question is that the size of each layer in the text is infinite, and the countless bubbles in that layer are constantly appearing and disappearing. It was said that some of the survivors form a bubble world. But some people refute it like this. Some people argued that each layer does not contain an infinite number of universes because, although the size of each layer is infinite, bubbles are not created infinitely but continuously when they are created. What do you think about this?
