Will the world really have an end?

There will be, but it's not necessarily an explosion of the earth.

The Mayan calendar predicts that mankind will be destroyed in the winter solstice on February 2, 20 12 1 day. Now a scientist overturns the doomsday theory of 20 12, pointing out that 20 12 is a wrong calculation result. The real doomsday is 2220, which is of course calculated according to the Mayan calendar.

According to the popular doomsday theory, the sun will reach the so-called galactic equator on February 2, 20 12. It is said that this special event will only happen once every 25,800 years. However, the reality is that the Milky Way does not have an exact silver channel. This is not a line. In fact, in the past few years, the sun has been on the silver channel from the winter solstice to the sun, and it will remain so in the next few years. As for the Mayan calendar, it is very different from the Gregorian calendar or julian calendar. When the Spanish conquered the Mayans in the16th century, the Mayans used as many as four calendars at a time. The oldest is the 260-day Zagreb calendar, which consists of 20 days and 13 days. Haab with a period of 365 days is 18 months, 20 days per month, and the fifth day of the year is called Wayeb. There are two kinds of calendars in Maya: long counting and short counting. Calendar number 3 is a short count, and the long-term cumulative day system is based on 20 days. The most widely used conversion between Mayan calendar and Gregorian calendar is GMT. GMT conversion is to set the Maya's creation date as 313.0.0 BC +0 14 BC September 6th in julian calendar or 3 165438 BC +065438 BC +0 in Gregorian calendar. 2012 65438+February 2 1 is converted from GMT. But what the doomsday prophet didn't know was that in the past 20 years, the conversion of Greenwich mean time has been strongly criticized by modern astronomers and archaeologists, which conflicts with another Mayan calendar-the Venus periodic calendar of 584 days. According to the researchers' revision, the end date of the fourth cycle of the Mayan calendar will be pushed back to 65438+February 2020, that is, 2 1, 22 or 23.
