  •  I don't (4+ / 0-)

    I don't disagree with you, it's just that I don't have a lot a faith in Man's ability to perceive and know.  We are so very very young as a species, it's completely plausible there are other dimensions of travel and energy transfer we're clueless about.

    I suspect if the day comes we'll be blindsided by a discovery technology that never occurred to us.

    [shrugs] How the hell would I know?  It's interesting, you could very well be correct. Peace be with you.

      many possible technologies and aspects of reality, but I don't see how that negates my point.  It may well be that such a civilization may not use radio for communication and has some radically unfamiliar technology, but to do what you suggest would require a level of technology and knowledge of the Cosmos that would surely make that an irrelevant as an impediment.  Peace be with you as well.

    •  You're missing the point. (0+ / 0-)

      The point is that the radio signals we send out (deliberately or otherwise) are way faster than the physical objects we send out.  Therefore it's impossible for the Voyager to reach somewhere without that place having already been awash in our radio signals for a long time prior to that.  That's the claim.  I don't agree with the conclusion though because physical objects don't spread out and dissipate like radio does, so it's possible for the object to end up eventually reaching somewhere far enough away that it didn't notice our radio waves because our radio waves. while they did precede the craft, were too weak to be detected as relevant.

      Which is why it might be a good idea to project the path of the spacecraft long after we lose contact with it, and start beaming narrow beam signals ahead of it to star systems we know it will be going near.  That is, if contact is our goal.

      •  Theoretically you have a point (0+ / 0-)

        eventually I guess, but realize that 100k years from now Voyager I will still only have traveled roughly the equivalent to the distance to nearest star.  Again, it will still be in the cosmic driveway 100k years from now, if you will. Long before it can ever "end up eventually reaching somewhere far enough away that it didn't notice our radio waves," we will either be extinct or have the technology to go get it and put it in a museum.
