Yes, this does have reference to some 2012 doomsday type predictions.
1. One theory states that the supermassive black hole at the center of our galaxy is of the type that has a rapid spin. Now, I have long been thoroughly interested and am somewhat well versed in the general physics theories about black holes. Just a couple days ago quantum physicists confirmed that in addition to most/all galaxies having supermassive black holes at their centers, the black holes also sparked the creation of the galaxies themselves. If you have no heard this, you may want to look it up. Now the doomsday theory takes into account one school of thought about spinning supermassive black holes that states that black holes of that size that also have a spin to them may very well adopt a flat donut/ribbon shape. This is one of a few theories about how spinning supermassive black holes behave. The line of thinking is that the donut/ribbon model would create a flat plane of gravity that extends through the galaxy along the galactic plane. This plane is created from the gravitational effects of the black hole itself at the center of the galaxy. What is the merit of this theory currently, in the scientific community?
2. Passing through this plain is thought to mean that we will face a few possible natural disasters due to the odd effects of the gravity wave/whatever it is. . The theory is supported by the fact that we have regular cycles of mass extinction events and ice ages, and that this time period would correspond with our crossing the galactic plane (every 30 million years or so). Now, I know that there is a debate on just what our position in the galaxy is and how often we cross the supposed plane. What is the truth in this part of the theory?
