Bonnie Malmat, editor at TrekToday.com, likes the original series from 1966 (deep space Nine is a close second).
The television shows were prolific: The Next Generation, deep space Nine, Voyager, and Enterprise.
Care to debate the merits of deep space Nine versus The Next Generation?
1. The notional location of any program that has gone off the trolley. Especially used of programs that just sit there silently grinding long after either failure or some output is expected. "Uh oh. I should have had a prompt ten seconds ago. The program's in deep space somewhere." Compare buzz, catatonic, hyperspace.
2. The metaphorical location of a human so dazed and/or confused or caught up in some esoteric form of bogosity that he or she no longer responds coherently to normal communication.
