This has been on my mind a lot lately. (no surprise there, i am always thinking about this stuff) Dave Talbot has done some pretty amazing research and compiled a couple videos called "Remembering the End of the World" and "Symbols of an Alien Sky" which are pretty mind blowing.
Here is a little preview for part two of "Symbols of an Alien Sky" called "The Cosmic Thunderbolt" that is coming out this summer. I can't wait to get my hands on it!
If anyone is interested I have a copy of his first two videos if anyone wants to check it out. I highly recommend them.
