In Eureka series 5 episode 1 (the others haven't aired yet where I live) the crew of the Astraeus
are in a simulation, where they think that they are in Eureka 4 years later.
Now I know that Eureka is very substantially self-sufficient, so I can almost accept that they didn't have any delivery drivers from outside, but surely they would have had SOME contact with people externally, that would have alerted them. It is not like the Matrix when everyone was in the simulation.
Do they never check news sites, or chat with colleagues outside Eureka? It wouldn't have to be often, but surely someone would have had some clue before the matrix started to break down?
