2012 Is not the end of the world, it is just that the earth has entered the photon belt, but at the moment of complete entry, we will spend 3 days in 0-degree space. Of course, many people will die. The magnetic poles will be reversed, and the 3-dimensional space will retreat to 0-degree space. It will undoubtedly be destroyed. But what is ushering in is a brand new world, and many, many people will survive those three days. Those three days are the huge chemical changes that occurred in the solar system in the photon belt. The atoms in the human body will also be reorganized, ushering in the 4-dimensional space, the fifth era. Personal understanding: The Mayans were not talking about the end of the world. They clearly wrote that the night of December 21, 2012 would come, and the dawn of December 22 would not come. Presumably the Mayans also live in the same space as us. Naturally, they cannot predict things in the 4-dimensional space. Moreover, there will be no daylight on December 22, but three days later, it is almost Christmas, and daytime will come!
