Cultures are diverse, and spatially spread. Out of a large
population a traceless transition with perfect recall of
expanding species has a probability indistinguishable
from zero.

This is the opposite of falsifyability. The machine elves
from hyperspace want to have a stern word with you.

You know what, go a top physics guy, and try that trick.
If he's polite, he'll show you the door.
