This is the last 12 minutes of the documentary “Secrets of Alchemy”. The theory is that there is proof on the earth that our galaxy explodes every 26000 years leaving a layer of an element called Iridium which is mostly found only in space. The theory came about from the discovery that what we once thought were “super novas” are in fact “Seyfert galaxies”. A galaxy that the center has exploded. Such a powerful blast that it consumes the entire galactic disk. Very good documentary to check out if you are curious or researching 2012. www.tearsoftechnology.com or http
