Jonathan, I was thinking along the same lines, except at the level of 1%. But even at 0.1%, and if we look in the other direction, the "others" (or, at least some of them) could also easily be 10 million years _ahead_ of us! (Brings us right back to Fermi again-i.e., where are they?) That intelligent civilizations could have started quite early after the BBang is supported by the latest studies showing that the earliest 1st gen stars in the universe may have been born as early as 200 million yrs. after the BBang--possibly, even earlier. More and more, I am coming to believe that the Fermi question is best answered by the conclusion that there are myriad ETIs in our galaxy, at all stages of development, including those megayears beyond us, and they aren't here because (even at the highest state of development) interstellar travel is just too difficult, or too costly, or too dangerous (for many reasons) -- or all of the above. Even if it _is_ feasible, IS travel may simply take many orders of magnitude longer to spread a civ. throughout a galaxy than we suppose. And orders of magnitude harder to maintain! There is no sub- or hyper-space, or handy wormhole stargates to act as shortcuts to the galaxy as in SF--it is sad to think of the myriad races, on myriad planets, looking up at the night stars, and feeling every bit as lonely as we do. I wish it weren't so, but... ...tonyC > -- > Rabbit arithmetic - 1 plus 1 equals 10 > Remove spam and invalid from address to reply.
