Scientists estimate that the two galaxies are twins in astronomical terms, both being around ten billion years old. Once the two galaxies coalesce into one gigantic galaxy, which could be renamed the Milkdromeda galaxy, the two enormous dark holes at the center of each former galaxy will merge into one.
Merging into one -- sounds a little like Twin Souls, doesn't it? Two entities created from one (as in the Big Bang), developing and growing, and, after years and lifetimes, finally meeting and melding and becoming one again. Pretty cool.
