​It wouldn't change the fact that if it was done between a heavy rock and a
slightly lighter rock a logical contradiction is produced, and that
shouldn't happen under any circumstances, therefore his theory that ​heavy
things fall faster than light ones can not be correct. And if he'd actually
done the experiment with a light leaf and a heavy rock he might have
started to wonder what exactly made a leaf move on a windy day and why the
wind didn't move heavy rocks. But of course Aristotle never did any
experiments, he just sat on his ass and thought, and he didn't even do that
very well.
