You can create paradoxical situations, that's what.  (Even if the "going
backwards" is only FTL travel, you can still do it, by radio control.)

Powerful evidence against the possibility of this kind of thing in real
life is the rarity of people who never had parents, and that sort of thing.
On the other hand, this can also be explained by Niven's Law: "If the
universe permits time travel and changing the past, then time travel will
never be invented in that universe."  (Because sooner or later, someone
will travel back and kill the inventor or something because they don't
care for time travel.)
