Where is everyone? / 모두 어디지?

The extra-terrestrial has spawned good books, mediocre art and bad movies; provoked serious speculation and a new science called astrobiology; and triggered a 400-year religious and philosophical debate, all without putting in a single appearance.

외계인들이 좋은 책과 평범한 미술과 나쁜 영화를 낳았고 진지한 심사숙고과 우주 생물학이라는 새로운 과학을 자극하고 400년의 종교상.절학 토론을 일으켰다. 그리고 한 번도 왔음 없다.

If life exists on Earth - a nondescript planet orbiting an undistinguished star in a neither-here-nor-there galaxy in an ordinary corner of the universe - then it ought to exist on at least some other planets around a proportion of other suns in at least a selection of other galaxies. There are at least 200bn galaxies, and each may be home to 200bn stars. Even if the evolution of a sentient, intelligent, technologically-aware civilisation is rare, the firmament should still be fizzing with life.

우주 의 보통의 구석에 있는, 별 문제 아닌 은하계에 있는, 눈에 띄지 않는 별의 둘레를 도는 특징 없는 행성들 중 하나인 지구에 생명이 있니까 적어도 몇몇의 다른 은하계에도 몇몇의 다른 행성들에도 생명이 있어야 한다. 적어도 2천억의 은하계들이 있고 각각 2천억의 별이 있는지 모른다. 느끼고 지적이고 기술상으로 알아차리는 문명은 드물더라도 생명 때문에 하늘이 쉿쉿거리고 있어야 한다.

But, as Fermi's Paradox asks: "Where is everybody?"

하지만 페르미의 패러독스가 묻다. "모두 어딜까?"

Sadly... [trying to commincate across these distances,] any signal dissipates as the square of the distance. By the time you get to Pluto, it's already vanishingly faint. So you send an ultra-powerful signal as a focused laser beam. How much energy would that take? How long could you afford to transmit? How many directions must you point the transmitter to cover the whole sky? (The answer to that one is 100,000 trillion). And what chance a citizen of an alien civilisation is tuned in when your one-second message whistles by at the speed of light?

Still, one in 100 Americans believe they have been abducted, cue for a short lecture on sleep paralysis, which manifests itself in pressure on the chest and the experience of being taken away [- known in Korean as a "scissor dream"] ...

그럼에도 불구하고, 100중의 한 미국인은 외계인으로 유괴한 걸 믿는데 가슴에 압력과 떠나가는 경험으로 나타내는 면마비(眠痲痺)?에 대한 짧은 강의를 하여 [한국말로 "가위눌림"] ...

Nice Blog!!!   I thought I'd tell you about a site that will let give you places where
you can make extra cash! I made over $800 last month. Not bad for not doing much. Just put in your
