Organic Matter Found In Canadian Meteorite
eldavojohn writes "From what sounds like the opening of an X-Files episode, Canadian scientists have reportedly found in a meteorite organic matter older than the sun at Tagish Lake in Canada. From the article: '"We mean that the material in the meteorite has been processed the least since it was formed. The material we see today is arguably the most representative of the material that first went into making up the solar system." The meteorite likely formed in the outer reaches of the asteroid belt, but the organic material it contains probably had a far more distant origin. The globules could have originated in the Kuiper Belt group of icy planetary remnants orbiting beyond Neptune. Or they could have been created even farther afield. The globules appear to be similar to the kinds of icy grains found in molecular clouds — the vast, low-density regions where stars collapse and form and new solar systems are born.' The article implies that life could potentially survive in these meteorites and maybe even travel through space — supporting the theory that life may have arrived on earth and evolved from that point on."
it's just carbon compounds.

Im actually interested, how do you measure the age of an object so old, when its not from earth ?
I mean the amount of radioactive materials that fall apart a thousand or so years after being 'inserted' into a certain object is valid only if we know the amount on the env surrounding it.
How do we know how old this thing is without actually being sure where it came from ?
Maybe there was less of the izotope in the env. ?
Or maybe there was much, much more of it ?
This is besides the point if the rock actually contains some fossilized life forms, if its a billion years younger or older, then this fact makes a pretty big difference, right ?
I understand that the age of stars can be measured by the spectrum (iirc, as light travels further/longer it leans towards one of the edges).
I also get how we can determine how we check the basic building block of an object a milion light years away by the light spectrum too.
But the age, when we are not really sure of the exact amount of izotopes in the env. ?
Could somebody educate this fool with a friendly wikipedia link ?
Free books for you? That was really sweet of her.
Perhaps you should have judged her by the act of giving rather than the gift. Rather than being condescending and judgmental (way to make her feel good, champ), you could have scored points and broadened her horizons by thinking about what she gave you and suggesting some other books she might have liked. Sounds like she likes shorter, punchier thrillers.
I'd have given her Gaston Leroux's "Phantom of the Opera", the collected short stories and cartoons of James Thurber, and maybe something short by literary like Ondatjee's "Running in the Family". How on earth can you know she won't like what you like unless you let her read it?
Either that, or you must be new here.

(And you're totally right, by the way. WHo gives a crap if she has awful taste in books? That would be like turning a girl away casue she doesnt play video games, or worse, likes the PS3)
