- There've been a number of suggestions for the answer to this one, mostly
- centered on the idea that when ETs have the kind of toys necessary for
- stellar travel, they commit suicide instead in nuclear wars. It may also
- be just that, since FTL travel definitely looks like an impossibility (unless
- causality isn't all it's cracked up to be), stellar colonization may just be
- more trouble than it's worth.
