Infinite is like 0: concepts. Placeholders. Useful tools. 0 represents "something was once here" or holds a spot open for normal numbers to show up in. Infinity is a placeholder for "we really don't need/want to go any further here"; there's more "further' to go. So, infinite gives us that religious awe feeling because it's BEYOND and 0 gives us that... 'empty" feeling because it's the "something was once here but now it's gone, its identity obliterated".
