The Science Of Why An Asteroid, Not A Comet, Wiped Out The Dinosaurs
“The most important thing is that we all learn what the correct scientific conclusion to draw is, and why. The impact event that occurred 66 million years ago was due to an asteroid, not a comet. We know this based on many reasons, including the very compelling chemical composition of the impactor, retrieved from Chicxulub crater and matched up with the layer of ash and clay found worldwide at the appropriate depth within sedimentary rock. A comet simply has the wrong properties, and the earlier study that claimed otherwise wasn’t just in error, but contained a series of unacceptably gross errors that should have resulted in the paper’s rejection.
The larger ethical issue, however, remains unresolved. What do we do about scientists who are so full of themselves that they willfully barge into a field they have no expertise in, and rather than work to gain that expertise and contribute meaningfully, they simply publish a superficial analysis to further their own fame and careers? This sort of practice must be discouraged, the same way we discourage those with no scientific expertise from contributing nonsense: through quality peer review. The alternative is to play an unwinnable game: scientific understanding by debate and public opinion. In the enterprise of science, it must always be facts and evidence, not persuaded minds, that carry the day.”
Did you read, back in February, that a comet, not an asteroid, wiped out the dinosaurs?
