Many people recently believe that in the year 2012 there will be some sort of enormous cataclysm and great shift in life. Some even believe all these changes are going to happen on a specific date, namely December 12, 2012. It is believed when the sun rises on that day, it will rise on the winter solstice, directly in the middle of the Milky Way for the first time in about 26,000 years. The position might cause the usual energy that typically streams to earth from the ccenter of the Milky Way will indeed be disrupted on December 21, 2012 at 11.11 p.m. This is said to cause a great shift in the consciousness of life on the planet and the planet itself.
Another prediction made is that, in 2012 the sun will reach its most active stage in every 11 years, which is called "solar maximum". The last solar cycle was at its maximum in 2001. It is predicted that an explosion will occurred with the energy of one hundred billion atomic bombs. This type of explossion is called a solar flare. Solar flares are pieces of the sun which leap into space, discharging strong electrical currents and radiation which travel outward into space. Coronal Mass Ejection (CME), a strong flare may hit a planet like Earth and this can cause some serious problems on our planet, it is believed this CME once hit Mars and in 1989 a flare hit North American continent.
There are also lots of people who claim that Nibiru, a non-existent planet supposedly discovered by the ancient Sumerians, will encounter Earth in 2012 and cause havoc. The sun becoming a supernova and incinerating the earth and global flooding are among the theories which many people think will cause the end of this world.
In fact, the link between global catastrophe and Mayan Long Count calendar-based prophecy is largely fiction. The Mayan themselves never said that the world will end in 2012 and modern Mayans have shown irritation with how their culture hhas been co-opted into pop culture notions and Hollywod blockbuster film promotions.
