- inactive, on 01/08/2008, -3/+8Because if Paul had been president during the '60s, we never would have gone to the moon.
- inactive, on 01/08/2008, -7/+12What the hell does this have to do with Ron Paul?
- inactive, on 01/08/2008, -3/+7Ron Paul would legalize comet dust for medicinal purpose. Wake up!
- FortyCaliber, on 01/08/2008, -0/+2Hence the THEORY behind the Oort cloud... The comets have mass and will collect more matter as they pass through the cloud (theoretically.)
Also, we discover new comets because they are freaking small and hard to see and some have a speculated several hundred year orbit... even thousands of years. Some may pass the sun just once in geological lifetime.
And not all comets lose all of their matter... comets lose only VOLATILE matter, that is, matter that is affected by solar radiation. Some comets become "asteroids" or "planetoids" when the ice matter has been stripped. - chugger1992, on 01/08/2008, -2/+4what _doesn't_ contain info about our solar system's past?
- FortyCaliber, on 01/08/2008, -0/+1FACE!
- JPOOPOO, on 01/08/2008, -0/+1More like a Rockumentary
- inactive, on 01/08/2008, -0/+1If you mean in the way Star Wars is a documentary...then yeah.
- FortyCaliber, on 01/08/2008, -0/+1And I'm sure that news, 4 years ago simply reported on ***** we've known since the 60's.
- bemenaker, on 01/08/2008, -0/+1And what a spectacular crash it was...... :)
- warriormonk, on 01/09/2008, -0/+0Can something that cannot be observed (even indirectly) be classed as scientific? The Kuiper Belt and Oort Cloud are often referred to as theories, so given the usual definition of a theory and the impossibility of observation, can (should) these even be termed "theories"? Given that it is doubtful that these ideas can ever be tested, one has to question whether the Kuiper Belt and Oort Cloud can even be considered hypotheses.
I would also like to see proof of your assertion that "some comets become "asteroids" or "planetoids" when the ice matter has been stripped." Has anyone actually seen this happen? Is there any evidence whatsoever that this can happen? - j1ggy, on 01/08/2008, -3/+3I'm confused as to why this is a recent article. It reports on news from 4 years ago that I read back then.
- inquebiss, on 01/08/2008, -1/+1Yay!
- jcaino, on 01/08/2008, -1/+1which sun? our sun? i have to wonder if comets can come from other galaxies...other suns, etc..
- kickcows, on 01/08/2008, -2/+1My name was on Stardust. Plus, I have some of the aerogel still (the stuff that the comet particles were collected on). My dad worked for JPL and helped get all of the parts for this experiment to be possible.
- jadattack91, on 01/08/2008, -3/+2Wow, Thats a shocker!
- inactive, on 01/08/2008, -4/+3Ron...Paul?
- Dolomite, on 01/08/2008, -2/+1No *****, Really?
- GorEjaKz, on 01/08/2008, -1/+0Playing Mario Galaxy will solve all your questions.
- inactive, on 01/08/2008, -2/+1Your mom.
- warriormonk, on 01/08/2008, -2/+0Oh so many problems here. First, the "Kuiper Belt" is purely theoretical. There is no evidence that such a thing exists. Same thing with the "Oort cloud". So why do we even discuss them? Answer: comets are evidence that the universe is NOT billions of years old. Every time a comet passes near the sun, it loses some of its icy material to evaporation. This stream of lost material is what gives rise to the characteristic comet tail. A comet can only survive a certain number of orbits before it runs out of material completely. If the solar system were billions of years old, there should be no comets left. So, scientists have been forced to come up with a source that can replenish the comet population, hence the imaginary "Kuiper Belt" and "Oort cloud". More atheistic faith in action.
