The space of spaces is pretty much just a container of inter-realm spaces. Not really much else to say except that this verse DOES follow the Berry Paradox. Also, the number of spaces it contains is approximately equal to aleph null. It's completely black due to the fact that the multi-realms inside of it are such a tiny fraction of it that they don't even appear visible, so the space of spaces is completely empty.
One thing special about the space of spaces is that it is a space of inter-realm spaces(es), meaning, it is a space of space of spaces.
A theory says that this is space of space of...(absolute infibity times)...of space of spaces. But it was disproved, because its not anything useful about that.
