“consigned to being a quick shorthand for alternate universes in science fiction”
Fringe fan?
‘Fringe fan?’
Didn’t see ‘Fringe’, but they used them in ‘Caprica’.
It immediately reminded me of the scene in a Fringe episode where Olivia is a small girl looking up at a passing Zeppelin immediately after transporting herself into the parallel universe. Whoever did the sound for the engine noise of that craft got it exactly right. The other point is that if blimps and Zeppelins ever become commonplace the nighttime reports of UFO's will go through the roof. Seeing something at night that big in the sky moving so slowly is quite eerie.
