I amost hate to start this thread because I am really not interested in post after post from the EPH crowd. But it seems to me that our models of comet formation are not being verified by the actual data. We believe comets formed in the cold outer reaches of the solar system and at least on their early passes through the solar system are full of volatiles. But we are not seeing that. We also beleive that comets are dirty snowballs, or snowy dirtballs, but we don't appear to be seeing that either. Last summer, there was very little wator vapor kicked up by the cometary impact, and now with the initial Stardust data instead of seeing volatiles and water, we are seeing minerals that only form in high heat. Plus, it was my understanding that olivene does not form in the presence of water, and yet Stardust is finding large amounts of olivene. Now, don't get me wrong, I am not advocating EPH, or any of the other theories whose proponents generally advance their theories by insulting others. But I think the data we are seeing is demonstrating that our most accepted theories of comet formation are wrong. Thoughts?
