Alright, try this on for size.
In BW era Cybertron, the Golden Disk has a lot of rumors surrounding it, one especially - that it would lead to a major Energon source. But why?
Earth's location is a closely guarded secret in BW times. Perhaps because of the advent of TransWarp technology, perhaps because they have interfered enough with Earth and wish to cut those kind of shenanigans out.
So in order to keep to location secret, Autobots had to control the flow of information, but how could they do that when the human themselves had launched probes out into space that held Earth's location already?!
The Autobots new of the probes, but the Decepticons and Predacons didn't. So after the war, the Maximals spent time scouring space for the proves to either destroy them or keep them in a safe place. In Vernoverse, Earth had been destroyed, so somewhat romantically the Autobots kept one of the Voyager probes as a memento, whilst destroying the other.
But from the Predacon side of things, why would the Maximals go to so much effort to find these probes if they were of little importance? Ideas were thrown up, ideas turned into rumors and thus the plague of non-factual information spread and suddenly the disk holds the key to the Predacons rising up to claim Cybertron!
Thoughts?
