I pretty much go with this guys thinking about Alien life and the chance we would ever get to see any:
$this->bbcode_second_pass_quote('', '
')So, to wrap things up: ET is very likely out there. But it's very unlikely ET has a light sword, a space ship or an index finger that lights up in the dark. ET is more likely a bacteria -- or at its best, a multicellular organism with no particular intelligence at all.
Hey, and besides. Just suppose there is, in spite of all the problems, intelligent life out there somewhere? Would we be at risk of being killed by them?
Surely, they'd have to be able to travel around. That's not an easy one, although science-fiction freaks carelessly say that such a civilization undoubtedly will use `worm-holes' for inter-dimensional travels. Or warp-drive, or teleportation. The cold fact, however, is that such things may well appear to be just impossible by physical law. It is so very easy to say: `Well, they're ahead of us, so they must have come up with something.'
Even then, the aliens have to find us. That too is a tough one. The Universe is so big. And our planet is only a tiny speck of dust in the endless nothingness. Okay, we send out signals into space, from our satellites, radio's and TV-sets. But our transmissions have a tiny reach in the vastness of the cosmos.
And even within reach of Earth transmissions, an alien would have to listen extremely closely to pick up our faded-away signal. Let alone the problem of which frequency to choose. Or the problem that an alien might prefer a very different technique than `radio signals'.
Okay, okay. Against all odds, our hypothetical alien has overcome all these difficulties, and has finally found us. What's up next?
Nothing much, probably. The aliens may want to study us -- a civilization that builds spaceships and has found out how worm holes work definitely is in it for science. They would study us in much the same way we study the microbes we'll undoubtedly find on Mars or Europa.
Yeah, some Independence Day-fans might grumble. But they might also be here to colonize our planet, to steal our mineral goodies!
O yeah, sure. What nonsense. Do you really think a civilization that builds intergalactic spaceships and opens worm holes doesn't know how to solve problems like shortage of minerals in some technical way? They'd have to be a race of real dumb-ass aliens, if you ask me.
