@Fighteer: You seem to be a very knowledgeable person.
: Awesome! Shall read after class.
I suppose I could wait (Or die waiting) if I had a reasonable expectation of it eventually getting there. Though as for the signal thing, Damn. The first idea I had was why not just make a signal that can't be missed, Like making a second sun there or something. Though after thinking about that for even a second I realized the obvious danger in producing a second sun, not to mention difficulty, or manipulating the first sun. My first thought for a potential non-sun based idea would be a full physical round trip, with the probe transmitting along the way back. Sooner or later We'd pick up the transmission.
Have the probe approach the solar system, Take what tests it can on the planet while orbiting around it, or the sun, and then do the good 'ol Gravity slingshot, using the same method to accelerate.
The specifics of that idea are unbelievably complex though, and would probably require some advancement in the AI field so the probe could pilot itself.
But I'm probably treading old water that has long been known in the serious space traveling circle.
: BLOOD FOR THE BLOOD GOD! SKULLS FOR THE SKULL THRONE! Though I'm afraid that there might be more similarities to 40K that far in the future, especially with the amount of religious zeal I'm becoming aware of.
