It is probably more proof that "more happened at Fukushima than we were told", and that "an eeeeevvilllll corporation only concerned with profits" (i.e., TEPCO) is just lying and covering it up. What really happened was that Fukushima melted down into the center of the earth and combined with all the uranium down there and made a mini-black hole that caused a time warp and sent all of Fukushima's radiation in to the past and caused that excess 14C we are seeing in those tree rings. Yeah, that's it. And we have a "scientific study) to prove it, and I am sure that people like Robert Alvarez and Arnie Gunderson and Helen Caldicott and Amory Lovins will probably be getting ready to verify it. And when that mini-black hole breaks through to the other side of the Earth, you know what that means:
We Are All Going To Die
