Betelgeuse, a red super-giant star located in the constellation Orion between 490-780 light years from Earth, is losing mass at a rapid rate indicating it's on the brink of type II supernova. Scientific estimates place the time of supernova within the next million years, but there remains one significant issue. Due to the distance there is a possibility that Betelgeuse may have already went supernova centuries ago and the light has yet to reach Earth. This is coupled with other prophetic 2012 apocalyptic doomsday scenarios as another sign to the world's end, as claimed the world would have two suns for a period of time, causing up to 2 weeks of intense light 24 hours of those days then fading back to the normal day/night cycle over several months as the supernova light dwindles. According to scientific research the only known Betelgeuse emissions, other than high levels of photons, is a high concentration of neutrinos which may be of great research value to the recent endeavors like the IceCube Neutrino Observatory in Antarctica.
Polar Shifts. As the Earth's magnetic field shifts, it's theorized that gaps may evolve in the magnetosphere as the process becomes chaotic before settling into its new position. According to geologists and other scientific research, the estimation for the last apocalyptic pole-flip, south to north, happened over 780,000 years ago. Evidence suggests a cycle of pole flips nearly every 50,000 years incidentally claiming Earth is getting closer to the 16th known polar flip since the last world devastating event. A very important note here is that a polar-shift does not happen over night. It is a gradual process over a period of 4,500 to 5,000 years by some calculations. This does not in anyway mean that one day it's beautiful and the next day is an apocalyptic terror-storm. References to associative 2012 polar shifts often neglect to include those significant details as it tends to remove the punch from the apocalyptic theory. One common phenomena related to polar flips as suggested by Earth weather and climate models does however include super storms with winds reaching the 300-400 mile per hour range. Recent weather changes over Europe have given rise to the super storm scenario though a change in weather patterns doesn't necessarily mean the Earth's poles must be swapping.
