By Soulskill from Slashdot's drake's-game-of-life deptartment
:
TravisTR points out some new research that aims to update and supplement the
Fermi paradox
— the idea that if intelligent life was as common as we expect, we should have detected it by now. The
academic paper
(PDF) from scientists at the National Technical University of Ukraine is based on the idea that civilizations can't expand forever on their own. The authors make the assumption that an isolated civilization will
eventually die out or go dark through some other means
, which leads to some interesting models of intergalactic colonization.
"In certain circumstances, however, when civilizations are close enough together in time and space, they can come into contact and when this happens the cross-fertilization of ideas and cultures allows them both to flourish in a way that increases their combined lifespan. ... Bezsudnov and Snarskii say that for certain values of these parameters, the universe undergoes a phase change from one in which civilizations tend not to meet and spread into one in which the entire universe tends to become civilized as different groups meet and spread. Bezsudnov and Snarskii even derive an inequality that a universe must satisfy to become civilized. This, they say, is analogous to the famous Drake equation which attempts to quantify the number of other contactable civilizations in the universe right now."

I'd hate to be the alien civilization that contacts us.
Aliens "We bring you an increased lifespan and superior technology."
Earth "We bring you lawsuits, dishonesty, and better ways to kill each other."

Which is exactly why no advanced civilization will make first contact with our species as long as it's in the state that it is. (Disregarding the near-impossibilities of FTL travel that would allow them to in the first place)
"Reality is merely an illusion, albeit a very persistent one."

It's only impossible by our definition of Science.

i know smog isn't a huge fan of kaku but i think he has a pretty good idea on how our advancement and contact with other civilizations might go
by his definition they probably wouldn't have anything to do with us unless we were a type 2, maybe type 1 civilization, because before that the urge to misuse powerful technology and blow ourselves up with it is pretty strong
also, the world is WAY too split right now, type 2 civilizations (again by his definition) consist of a single spoken language, no issues with nationalism, etc

I like Kaku for his philosophies, I just think his science is a bit shaky. I think he's an absolutely awesome human being who I would love to meet.
