It is a very practical theory. Although they might be erring in looking for a large event when a small one lasting for only three years could do it and five certainly would. Civilization would be able to survive one bad harvest, two would cause some crumbling and three could lead to total collapse. People would flee the starving cities. The survivors would be people with skills in farming, hunting and gathering and artisans with practical skills. The rest would die off quickly.
Scholars, builders, designers of fine art and civic leaders all dead. Bye-Bye Civilization. Hello, “bang your neighbor over the head for his stew pot” time.

"Scholars, builders, designers of fine art and civic leaders all dead. Bye-Bye Civilization. Hello, “bang your neighbor over the head for his stew pot” time." Exactly. I was discussing the 540 AD (Probable impact) event with a FReeper the other day and the fact that the Dark Ages (Beginning in 540 AD), were called the Dark Ages because it was dark. He said no-one had written about that during that time. I said, the writers were all dead. LOL. (actually it was written about)
