[QUOTE="happyhacker, post: 6048036, member: 625225"] I was thinking about the signals Mankind has sent out from Earth greeting other races out there. Is it reasonable to think that even if some being received the signals (data) they would have no idea about locating Earth because it would be in somewhere else in the Galaxy/Universe by then? So some people's worry about giving a conquering race our coordinates is groundless and a waste of effort anyway unless by some Galactic or Cosmological reference one can compute the path. I do not have the knowledge to apply any maths to this even if there is any. [/QUOTE]
