When in the Battlestar Galactica time line did the beacon from the fake Earth that carried a form of bubonic plaque actually get launched, and why?
The way I understand it, there was a diaspora from Kobol (why?) with 13 colonies leaving to space. One got lost and made it to a fake-Earth. Fake-Earth gives rise to its own fake-Earthlings and Cylons. These Cylons nuke fake-Earth and almost wipe out the fake-Earthlings. But some scientists (the final 5) invented reincarnation and sold it to the Cylons so that they would STFU.
So questions are, where did that beacon in space that briefly infected the Cylons (with the bubonic plaque) come from? They said it was from the fake-Earth, but why was it there to begin with, and when did they deploy it?
