Napier vindicated

20 Mar 2012

Following on from yesterday (Bill Napier email from 2005) the YD impact hypothesis is revisited at in which the author begins by saying the team presenting the YD boundary event were not writing from a solid astronomical model - and that is what got them into trouble with the critics. This was because they were relying on Toon et al and the estimate they made that it would take a 4 mile wide bolide to account for a continent wide debris layer. Dennis Cox, on the other hand, has stuck rigidly to the idea of an airburst and Clube and Napier's hypothesis concerning the Taurid complex.
