Our world is big and messy, but we agree
that certain facts are objectively true:
Earth is not flat, despite a minority
of people still dispute this hitherto.
What else, we all concur a billiard ball
hit by a cue with ordinary force,
will never just go through a masonry wall
without leaving a hole in a brick course.
But in the microscopic quantum realm
particles can be in two places at once,
so how does objectivity unwhelm?
It's natural selection: At a glance,
the more observers look at the same cat,
the more consensus will be formed hereat.
This Darwinian revue
was known to occur for atoms and all that.
We prove it holds for infinite "cats" too.
