Origin of Dinosaur-Killing Asteroid Remains a Mystery [...] -------------------------------------------------------------------------
What happened to the old theory that it was a comet (e.g., megaTunguska)? If the chemistry is wrong, how about a retrograde comet killing off most of some asteroid's orbital angular momentum?
So if a small asteroid, or that falling satellite, manages to slip in and kill some people, is Italy going to charge a bunch of astronomers with manslaughter? Or in the U.S., just a civil tort? --rwg
