They had two shows on ancient socienties and their conquering of astrological physics. I've been to the ancient Mayan ruins at Chitchinetsa (sorry about the spelling) in mexico and was amazed by it. The way they were able to build these mammouth tempeles that are in perfect alignment with the summer and winter solsists as well as the equinox is amazing. The part that kind of scares me is them predicting the end of the world on december 23rd 2012. I'll make sure to run up my credit cards before that day so it won't matter. But they're calendar is more exact than our calendar system. They use some sort of standard unit in their archecture that accurately calculates the circumfrence of the earth. The second show was about egypt, cambodia, and mexico and how their archetecture basically reflected the stars in the sky. Does anyone else find these things amazing. These cultures. How did were they all able to build these temples in alignment with the stars at the same time in many different parts of the world, simply fasinating. What are your thoughts? Sorry about the spelling, I'm more of a science, math kind of thinker.
