Ok, I was listening to the radio and this caught my ear. They were talking about how with the certain alignment of the planets, and Venus will pass in front of the sun. When this happens, the Earth will not be at an angle on it's axis! They were saying it will be straight up and down which means that we will not have any daylight! Now I didn't hear the entire show, and I am not too smart on the Maya calender. Has anyone else heard of this?
I found some links
