NASA Overjoyed at Catch From Stardust

mknewman wrote to mention a New York Times report that the Stardust project has exceeded NASA scientist's expectations. From the article: "While they had expected mostly microscopic samples, the researchers said, a surprising number of the particles were large enough to be seen with the naked eye ... The cargo in the Stardust's sample container, which was opened Tuesday, 'was an ancient cosmic treasure from the very edge of the solar system,' Dr. Brownlee said. Scientists believe that these particles are the pristine remains of the material that formed the planets and other bodies some 4.6 billion years ago."

      God is still here as well. Without faith you are blind to him.


      God does indeed exist, as do all the other gods that have believers who think about them. Dieties are a type of meme, and as such are organisms just as real as any biological organism you could name. The difference is that while fish, lemurs, and humans are self-reproducing entities made up of collections of organic cells, memes are self-reproducing entities made up of human beings' collective thoughts and beliefs.


      Like their organic counterparts, memes compete for resources (i.e. human attention), fight each other, interbreed, become extinct, adapt and evolve. It's even possible that they could be sentient, although since they are limited by the speed of their "neurons" [i.e. human communication], I suppose they must think and perceive very slowly (perhaps years or decades to complete a thought?).


      Note that there isn't anything mystical or supernatural involved here: it's a simple application of functionalism: a clock made out of steel tells the time just as well as a clock made out of wood, (or water, or silicon), and likewise an organism that uses humans as "cells" and speech as its method of reproduction is also valid.


      So while I'm rambling, I'd like to point out some of the adaptive features the "Christian God" meme has evolved to help make it so robust and evolutionarily successful in the modern environment:

      1. Exclusivity. "Thou shalt have no other God before me". Like a sperm plug placed by a mating crab in the female to prevent competitor's sperm from gaining access later, this commandment ensures that competing dieties will find it very difficult to gain access to the believer's mind at a later date
      2. Aggression: Variants of this meme often seek not only to snuff out remnants of competing memes in its own followers' minds, but will also direct followers to seek out and destroy competing memes whereever else they exist. This aggressive behaviour helps the meme keep competition to a minimum
      3. Faith. By requiring the believer to reject critical thought and rely on faith alone, the God meme minimizes the risk of rejection by its hosts in response to countervailing evidence.
      4. High communicability: "Follow me, and I will make you fishers of men". In its Evangelical forms, the Christian God meme can be highly contagious and can spread through new communities in relatively short periods. The meme often sends out runners across oceans and invades foreign ecosystems. By continually finding new niches in which to establish itself, the meme greatly decreases the likelihood of its being wiped out or marginalized by other memes.
      5. Adaptability: Unlike less flexible memes that only flourish in their native culture, the Christian God meme has proven itself adaptable to many different conditions. For example, in capitalist nations, God takes on capitalist qualities... when the mood is war-like, God supports war. When peace is desired, God is for peace. Because the meme is so abstract, followers are able to easily integrate it into their existing mindsets, and this allows the meme to spread to the greatest number of people
      6. Mimicry: The meme has learned how to mimic the qualities of other memes as a way to attract additional followers. Early Pagan and Roman rituals in particular were incorporated into Christianity for this purpose, and remain present there today.


      So yes, God exists, and as a memetic organism it is doing quite well -- it's certainly in the top tier of "charismatic megafauna" of memes, along with Buddha, Allah, Technology, and Money. Congratulations on picking a winner!

    The wind god and the rain god and the thunder god and the fertility god obviously exist, by definition. (They are what causes these phenomena, which science can only partially explain).

    I'm not sure about the upper case G gods. They were invented more recently. I'm not even sure how many there are - are the Xtian, Jewish and Islamic godz different?

    To me they're all a big con game.

    Hey, weren't they supposed to catch this probe by helicopter as it parachuted down to Earth? Seems like I remember reading about that, but I'm not sure if this is the same mission...

      Um.... let me get this right-

      Helicopter= spinning blades on top.
      probe= thing with wind catching bag tied to it with long rope coming from above.

      Helicopter + probe=catch?
      NO!

      Damnit... smart ass comment made me do my own darn Google search. Genesis was the mission and the parachutes didn't deploy so it smashed into the ground and the helicopters obviously couldn't catch it. Note the photos of the helicopters catching probes on training missions. I believe there was a sensor installed upside down. I read recently that the mission is considered a success though because the collectors were recoverable. There was some more recent news on this this week, I just can't find the link.

      Oh well, so there I go, answering my own question.

      That's OK I was being a smart ass, they probably use a hook or something but, you are right on the missed catch and crash with the Genesis probe.

  65. Partially wrong! by Gogo+Dodo · · Score: 1
    I was partially wrong.

    On Side A of the collector, the particles are from the comet. On Side B of the collector, the particles are from the cruise phase so that would be interstellar particles. However, none of this was "space junk".

    So I was correct 2 out of 3 times.

  70. No oxygen in aerogel by mangu · · Score: 1
    IIRC, aerogels are made by making a silica gel in liquid carbon dioxide and then drying it in super critical conditions. They are very porous, exposing it to vacuum will make sure all the gas is evaporated, but some of it may remain adsorbed to the (very large) surface.


    About the opening of the sample, I suppose it's done in the best vacuum they can get. It's a logical assumption that they will do all the studies they can in vacuum, and if the samples are pressurized at all for some reason it will be in an inert gas.
