Pioneer 10’s power source has finally decayed to the point that we probably won’t be receiving any more signals from it, so off it goes, spiralling into the black void (read all about it).
I wonder what will happen when it gets discovered by aliens, which we all know are real and exist somewhere and communicate by telepathy.
Maybe they will think that Pioneer 10 is an old crippled human warrior, lost on his way home from battle. And they will be able to trace its source, and will be surprised when they arrive on Earth to find that the dominant species (and I use this term very carefully, reserving the right to change it at a later date) are carbon-based.
Or maybe they will just say “Wow, how DO those Earthlings manage to pick up such a weak signal? Evidently they must know that we are here, and this craft is clearly a declaration of their technological superiority, and a prelude to war. Quick! Pre-emptive strike!”
And so the aliens will rush over to Earth, all tooled up and ready for a ruck, only to find that we have all been killed already, because some guy with a hard-on for fighting managed to get into power.
