Theory:Doctor Who television discontinuity and plot holes/Mission to the Unknown


 * Why would the Daleks announce their secret plans on the loudspeaker?
 * Only the people who were involved in the plan would have heard it so there was no need not to use a loudspeaker.


 * Why are the Daleks reffered to as "the power from the Solar System"?
 * It's pretty clear that, for some reason, almost every astronomical term we use means something different in the "galactic universe of the solar system" of Doctor Who. I think we have to assume they're using some term that has no real equivalent to anything in our world's science, and "solar system" is just a bad translation.
