well you can think about it with how they explaind it in i hart hukabees (or how ever you spell it)

that the world (or infinate space for this case) is like a blanket. in that between everything there is something fillinf that gap like between each atom there is something there and between what ever that is there is something and so on and so forth.

but then again im bad at explaining things (especally on the internet) so it probably makes no sence and you should just ignore this post.
