Today, a very learned friend of mine and I were discussing the difficulty of the literal interpretation of Noah's ark. That is, we could not fathom how multiple samples of every animal on earth could have fit on a boat.
We got very creative in our interpretation, but we still were forced to admit that it would have to have been an open miracle for it to work.
We were also surprised to realize that neither of us could remember having ever heard of anything from חז״ל seeking to explain the phenomenon. We assume that they must have been aware of the vast number of animals in the world, even if they did not know to the extent we know today just how vast that number actually is, and they must have also known that such a large number would be impossible under normal circumstances to fit under one roof, however large, not even accounting for food and waste.
Are there any sources in חז״ל that attempt to address this difficulty?
