Parallel worlds
If the Earth's magnetism were to be reversed, as scientists claim has happened previously and could happen again, would everything we know and understand be reversed? Would we see ourselves come, or go?

It would make navigation by magnetic compass difficult but the primary concern for us would be what if any effect it has on protecting us from harmful solar radiation.
Although the reversals are rapid geologically, I don't think they would take place fast enough for any given generation to notice. The Magnetic Poles do move around enough for map users to need take the drift into account, but the extent of the wandering (a rotation?) is not large.
