After Venus is destroyed by an invading fleet, Earth and Mars end their dispute in order to
put together a fleet that can travel back in time to extract vengeance on the invaders. I
like Brown’s work a lot, but not this story which had gaping holes, not the least of which
was a problem with the units of c raised to the c power (one of my pet peeves).
In ten years, traveling forward in space and backward in time, the fleet would have
traversed just that distance—186,334186,334 miles.
