About the first link, I'm not sure I see the guy's point. He complains about the magnification and where it was published, but has no real reason why it's fake. In fact, I'm not sure he pointed out one shred of actual evidence for its non-truth. |

PZ's point is that the credibility of the paper may be questionable due to where it's published. He also questions the paper itself as it seems to contain explanations about "carbonaceous chondrites, not well-honed arguments edited to promote concision or cogency." He does qualify his claims, if a bit harshly, but I'm not concerned with his tone. He also links to similar pieces about the paper, linked below. |

Plait says nothing of the sort. |

It's funny. "The Journal of Cosmology", where the paper was published, lists Roger Penrose as a guest editor. He's sorta a crackpot but he's also undeniably one of the heavyweights of the twentieth century. They list him as specializing in string theory which is weird because he's been pretty down on string theory every time I've read anything by him about it. |

Yeah, I won't get excited. |
|
If it was true it would be pretty exciting. |

Panspermia is a pretty silly 'explanation' to be honest. I highly doubt it is true. |
|
You need to read some Carl Sagan books you pessimist you. |
|
You don't know what panspermia is. |

I read the Google preview of the wiki page.... |

Yes but A implies B doesn't mean that B implies A. -_- |

I think it's a good explanation of how life got here. |

Well, mainly because planets are so much bigger than asteroids. They have vastly more variation in the different chemical environments they host (plus asteroids are totally lacking in many respects such as substantial atmospheres to allow for cycles involving gases), and they have vastly more of those chemical environments, so life is vastly more likely to arise on a planet. |

This is the only point that isn't absolutely valid. The meteor is often still cold when it lands. The heat will melt the outer layer which the meteor sheds off before the heat transfers to the interior. So meteors can actually land and develop frost on them. This isn't always the case and depends on a lot of variables. |

Some meteorites come from other planets, not just asteroids. We have found meteorites on Earth that originated from the Moon and Mars (as in something hit them and some debris ended up on Earth). I don't necessarily subscribe to panspermia but that would be the most likely explanation if it were to be true. If anything, Earth is probably the most likely source for panspermia of other worlds (if there were habitable planets/moons nearby). There have been quite a few large impacts since life began on Earth, maybe some Earth bacteria is floating around in space on ejected debris. |

Well we weren't really talking about how life arose. We're talking about possible ways life got here. I agree completely with that btw. |
|
Nothing is going to be too different from how life on Earth works. So yes I do have a fucking clue. |
