Have you seen or read Ghost In The Shell? I think you'd like it. It aired on SBS earlier this week. If you haven't seen it I recommend picking it up from a comic store or on DVD.I'd lend you my comic book, but it's in Japanese.
We haven't even fully explored our own planet, let alone space. e.g. the ocean depths still remain a mystery to us - it's not uncommon for people to discover new species. We know so little about species like the giant squid -- most of the specimens we've seen have been juveniles. Sightings of full grown adults have been rare.Originally Posted by Hursticon
The immense resources and cost required to even travel to Earth from the nearest galaxy would make occasional visits impractical unless they were able to profit from coming here (e.g. conquest, plundering resources etc.).Originally Posted by Hursticon
Imagine if we discovered the existence of an intelligent but primitive alien species in Alpha Centauri -- say with the cognitive level of chimpanzees. Would we bother to spend zillions of dollars to send a mission to study these creatures if there were nothing to gain? If they had something we wanted, like say Unobtainium, then we'd colonise them. If they resisted, we'd happily displace them (or even annihilate them).
