As evidenced above, many others have pondered whether we are
really small in the big scheme of things, (smaller than we already "know" we
are) .
But I am glad you brought it up and I think it is a totally plausible theory (that the "multi-verses" are a tiny part of something unimaginably
big), and I would love to see some more thoughts on the subject.
Interesting we could be a virus in some massive lifeform, and I suppose because of the size of "whatever it is" (speculation) we could have been in
the midst of a stream of puke for the "pukeyverses" entire existence, but because we are so small, it takes a
very very long time to hit the
toilet bowl

But seriously very interesting.
