I keep having recurring visions of a sphere with a diameter of Graham's number, somewhere outside the multiverse. Is it possible such a thing could exist, /x/?
I don't think an object like that is anywhere within the realm of human comprehension.
Sleeping people tend to attach meanings to images regardless of whether they actually belong together.
That being said it is fun to speculate on such things. It's not really possible for an object to exist "outside" of a universe. There isn't any space and therefore there can't be any mass.
But the universe is infinite, as mind boggling as that is, the space is there for such a sphere, and it wouldn't even make the it cramped in here..
