Forgive me if I'm being ignorant, but I could see no relation in what you said to my post. What does the evolution of humans have to do with the subjects I talked about? Maybe I'm missing something?
Humans have only been around for a half-million years
CHAOS, are you saying that the Earth will pass through the galactic plane in 2012?
Yes, I'm aware this theory is not a new one. I was merely trying to provide some good scientific backing for this theory, and put the facts into a nice coherent thread where I could link together the galactic cycle with the Mayan calender and extinction cycles. I'm sure what I've presented here has been very useful for some people in confirming their suspicions.
This is not a new theory about 2012. I have heard it before. So for me personally, it won't change my understanding of the 2012 theories in any way.
I am not sure which piece of information you have presented will convince me that 2012 will have great significance?
If this 60-65 Million year extinction cycle holds up then we could still be hundreds of thousands of years from the next big event. You see it's not exact, we're dealing with rounding and estimating years IN THE MILLIONS so the margin for error is massive
Of course the Sun won't keep on going in this direction forever. In fact we approximate it's motion by an 'epicycle' on top of the mean motion around the Galaxy. The period of oscillation in and out of the plane of the galaxy (up and down) is about 70 million years. This means that we pass through the Galactic midplane about every 35 million years which some people have compared with the period between mass extinctions on Earth to come up with yet another doomsday theory. In fact it is true that the number of cosmic rays which hit the Earth will increase during the (about a) hundred thousand years we are closer to the Galactic plane. There have also been some plausible theories about the overall temperature of the Earth increasing (with the relevent climatic changes that implies).
