Thanks to u/Quantum for the topic:
The theory is that as our solar system moves around the center of our galaxy, it travels through a magnetic field that reverses the polarity of solar system roughly every 12,000 years. This may cause the sun to micro nova and the earth to rotate 90 degrees.

Love the SO links. I follow it every morning. Got turned on to it back at ruqqus. Really good stuff and Ben is amazingly smart.
Somewhat sure about Ben. Remember, geologically speaking a thousand years is but a day. I'm sure of the science, just nobody can really pick a day or even a year. I use his daily updates to get an idea of what's coming, but nothing is absolutely certain
