Fringe : Season 3 : Episode 14 : “6B”
Earth-1 (several decades later than Earth-2) is finally starting to come apart at the seams, with mysterious ghostly goings-on in an apartment building. Who you gonna call?
I’m not sure if the glowing-door-outline counts as a Door of Doom, but it certainly reminded me of Dana’s apartment in Ghostbusters.
Walter requests that Peter grab a “digital spectrometer”, which is kind of a pleonasm because almost all modern spectrometers use digital processing and display. Spectrometers measure electromagnetic radiation, but are generally only useful in controlled settings (such as a laboratory) as they require quite strict sample preparation procedures. By way of counterpoint to all this digital technology, Walter also brings along his ancient Geiger counter (he calls it a radiological survey meter), which I believe is a Victoreen Fallout Detection Meter from the Cold War. This may be the same instrument he uses in Bad Dreams (season 1, episode 17).
As other Futurama fans have pointed out, coin flips in Universe-2 have the opposite outcome.
Ah, quantum entanglement. No, it does not really apply to people (for one thing, there is no information exchange) – but I feel that Walter was just using it as a metaphor for how the two Universes are linked.
If distance makes no difference to the universe-ripping, the FBI could have just forcibly removed Alive from her apartment and convinced her that she wasn’t seeing her husband once outside, without risking two of their least-replaceable agents.
