They have established conclusively that what has been thought of, as the cosmic background radiation of the universe is really the static and radio noise generated by millions of civilisations communicating across the cosmos.
This was spelt out in the newly translated science program broadcast at the end of the news program accidentally picked up last year (see Alternate Universe, April 2000)
As the program was designed for sub adults of a wide range of species, and was therefore put in simple terms, it was possible for us dumb earthlings to figure out at least half of the program.
It was pointed out that this radiation was essentially the radio version of space junk, and was causing much concern to sentient beings around the Universe. Fortunately for our own reputation, the Earth’s contribution consisting of radio transmissions, sitcoms etc, had not reached far enough to reach any society which was radio literate, so we apparently have around 42 years before that happens, after which it will take more than a century for abusive complaints to reach us.
Should we achieve faster than light travel by then, by mastering Philosorapture science (see page 5), it will be possible to send an apology in advance, not only for the interference but also for the dismal quality of most of the broadcasts. It has been decided to pass off Parliamentary broadcasts as Sitcoms in order to fool them as taking us as seriously intelligent.
