"It's coming from Tokyo Tower."
   "Japan?!" Fox was astonished. "Okay, book us two
tickets to..."
   "Mulder," the caller told him, "the message was
transmitted in 1970. I just wanted to tell you before
you went off on one of your wild goose chases."
   "How could a signal that originated in 1970 be
received in 1997?" Fox asked as the caller
disconnected

Okay lets play pretend here.  While this whole thing is fairly
interesting the one problem that arises is this small bit here.  If
these two little universes are existing simultaneously, then wouldnt
Mulder have perhaps heard of the strange phenomenon that occured at the
tokyo tower in 1970.  Lets face it the building disentegrated, kids were
FROZEN, a super giant cannon fired and everyone saw the sky flare up and
the clouds swirl around and all sorts of odd events.

So my point is this if this occured in the same universe mulder not
knowing the significance of the tokyo tower and 1970 would be like him
not knowing what the tunguska blast is.
