On Logic and Alternate Universes

Andromeda collides with Milky Way, of the two how many galaxies will remain afterward?

This is not represented by something like 1 + 1 or 2 + 2. Collision of galaxies is not exactly the same as adding them together.

Just using raw numbers sure. But then numbers and arithmatic are a representation of specific concepts, 2 sets of 2 don't meet the parameters to be set of 5 because that's not what 5 means. If numbers don't equal themselves then causality is fucked and whatever lives there wouldn't be able to comprehend the question.
