The Cosmic Winter gives us a quick glimpse back and history and a comparison across the various scientific fields yielding a thesis that is so stunning and real that it shakes the reader to the core.
He covers a lot of history and myth, which may bore the more hardcore scientist or casual reader, but it is necessary to comprehend all that follows. It also makes for a great review of some ancient history that I had otherwise been only marginally exposed to.
After covering the history and mythology he moves forward and gives us hard data, tons of it, regarding actual impact events. He brings three forth that have happened in the last thousand years that demonstrate these cosmic missiles can have the destructive equivalent of a multi-megaton nuclear explosion.
He then moves back in time and gives us more history, that of actual impacts and the records left by ancient societies. When you add up all the research done, all the data in this book, it's hypothesis becomes almost undeniable. It's amazing that so much evidence can be gathered and yet the mainstream scientific community is still in doubt, still perpetuating a theory that has been disproved over and over.
It's almost as if we're still in the age of Gallileo, and decrying the planet as round and revolving around the sun is treason against god and humanity! Seriously, if you want a solid education on the phenomenon and realistic ideas based on solid facts check out this book. It rocked, no pun intended.
