DailyDirt: Detecting Signs Of Life

from the urls-we-dig-up dept

Looking for extraterrestrial life has been a largely fruitless task for many decades. There have been a few times when people thought they might have found evidence of life that wasn't from Earth, but upon further analysis, those discoveries weren't so clear cut. Still, the search for ETs is on-going, and here are just a few links on some ways to find alien friends. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post.

    perfect job security...

    Since you can't really ever PROVE the existence of life from other planets... as long as you can find some circumstantial evidence, you'll be looking and looking and looking...

    Those marble thingies wouldn't happen to look anything like this:

    And I'm looking to the sky to save me, I'm looking for a sign of life.

    Re: MARSbles

    Those "blueberries" on Mars were actually predicted to exist by some geologists.. but there may be abiotic processes that form similar spherical stones.

    Universe

    Since life exists on Earth, and the universe contains 100s of billions of galaxies each holding 100s of billions of stars, and the universe is nearly 14 billion years old, it's highly unlikely that life doesn't exist or hasn't existed elsewhere. As it's impossible, as far as our understanding of physics, to travel faster than light, we'll probably never meet them; but these efforts to try and find it are totally worth it, if only to dispel the notion that people are the only greatest thing since the big bang. Maybe that would encourage humans in the future to work together to accomplish great things instead of perpetuating the greed and counter-productive indiviualism that is the basis of our society.
