I guess this would be along with the idea of a gamma ray burst. These theories are very interesting, but do have some problems with them. I often feel for many of these mass extinctions and strange events that a perfect storm of many unrelated events, or a sequence of events must occur.

Also speaking of this, according to some astronomers the Sun is overdue for a massive solar storm which could act like a temporary EMP type burst and cause massive blackouts and even loss of satellites and telecommunications.

Gamma ray burst 40,000 years ago? Yes, but that wasn’t the end of it.

The matter blown off by the supernova arrived here about 13,000 years ago, creating a crater on the bottom of Hudson’s Bay, a crater on the bottom of Lake Superior, and literally thousands of Carolina Bays all around the country. Oh, and the North American ice pack (over Canada) was pretty much blown to smitherines.

The guys who wrote this book present very specific evidence, especially the supporting data of a spike in the amount of iridium and fullerenes in the soil at the 13,000 years ago level, about when mammoths and Clovis man disappeared.

Everyone ridiculed Harlan Bretz when he claimed to have found proof of catastrophic flooding in eastern Washington State. It was decades before his findings were accepted.

Look at the scientific evidence before you scoff.
