Scientists debunk doomsday prediction: Scientists debunk the so-called "doomsday" prediction by using Mayan calendar for the first time. The Mayan calendar did not end in 20 12, so the Mayans themselves did not regard this year as the end of the world. However, 20 12 12 2 1 (winter solstice) is definitely an important day for the Mayans.

Poster of 20 12

A big crack appeared in the ground of California, USA. The building collapsed like a match, the whole seaside community was dumped into the sea like garbage, and Huangshi National Park became a mass of fireworks. The subsequent earthquake triggered a tsunami, the White House was smashed by an aircraft carrier, and even the roof of the world became Wang Yang. ...

This is the scene in the blockbuster "20 12" just released. The "20 12 catastrophe" described in this film has become a hot topic on the Internet. So, will there really be a human catastrophe at 20 12, or is this just an ordinary number?

Lies 1: The Mayans once predicted

Old Maya: There is no such thing.

For the first time, scientists used the Mayan calendar to debunk the so-called "doomsday" prophecy. The Mayan calendar did not end in 20 12, so the Mayans themselves did not regard this year as the end of the world. However, 20 12 12 2 1 (winter solstice) is definitely an important day for the Mayans. Anthony Avini, an archaeologist at Colgate University in the United States, is an expert on Mayan culture. Avini said, "In the Mayan calendar, 1872000 days is a cycle, that is, 5 125.37 years."

Guatemalan Mayan elder picton also said: "There is no such thing at all!" He even said that the doomsday theory originated in the west, and the Mayans never had such an idea.

Lie 2: Solar activity broke out.

Scientists crack: not enough to "destroy the earth"

A doomsday theory holds that an extremely violent solar storm will break out in 20 12 years, and its energy is equivalent to 1000 billion atomic bombs. Previously, cosmologists had predicted that 20 12 years would be the peak of solar activity. However, the National Oceanic and Atmospheric Administration (NOAA) recently said that the latest forecast shows that the solar activity will not reach a small peak until 20 13 years, but the sun is still a little "lazy" recently. Please note that even during such a "small peak", the activity of the sun will not be too strong, and it will only cause some interference to radio transmission.

In fact, solar flares are regular, and their outbreak period is about 1 1 year. Violent solar flares may destroy communication facilities and other things on the earth, but scientists have never said that the sun will release a solar storm strong enough to scorch the whole earth, at least not in the short term.

Lie 3: geomagnetic polarity reversal

Scientists cracked: the geomagnetic field is weak and changes slowly.

Some predictions about the end of the world claim that by 20 12, the earth's poles will reverse, the crust and the surface will suddenly separate, and magma will gush out from the core. Separated continents will fill the sea with the whole mankind, and disasters such as earthquakes, tsunamis and volcanoes will appear together.

Scientists refuted these so-called predictions. Adam Malouf, a geologist at Princeton University in the United States, has made in-depth research on "bipolar rotation" and Mayan prophecy. Maarouf believes that some magnetic signs in rocks indicate that the earth may have experienced such drastic magnetic field changes, but this process is a slow process that lasts for millions of years, so slow that human beings simply do not feel this change.

CoCo Lee, secretary-general of the Jiangsu Astronomical Society, said: "In fact, from the perspective of the history of the earth, there have indeed been drastic magnetic field changes." CoCo Lee said that in the past 78 million years, the earth's magnetic field has reversed 17 1 time, and the last magnetic field reversal occurred about 780,000 years ago. However, the degree of this tilt is very slow. Moreover, the earth's magnetic field is weak. In general, the average intensity of surface magnetic field is only 0.5-0.6 gauss, which is only about 65,438+0% of that of ordinary magnets. A magnet will not affect us, let alone a weak geomagnetic field. "So, we can only say that it is indeed possible for the earth's magnetic pole to change, but it is not enough to cause devastating disasters."

Lie 4: The sun, the earth and the planets are in a straight line.

Scientist: 1982 9-star gobang human beings also passed safely.

Astrologers believe that in 20 12 years, the sun, the earth and the planets may be connected in a straight line, and the sun's line in the sky will pass through the center of the Milky Way, which will lead the earth to be pulled by more powerful unknown cosmic forces and accelerate the destruction of the earth.

"This connection has no scientific significance." CoCo Lee said with a smile, these so-called "several stars linked together" phenomena are reflected in many film and television works. In fact, in 1982, there was a phenomenon of "nine stars connecting beads", and no catastrophic events occurred. In 20 12 and the following decades, there will be no planets in a straight line, and it is impossible for the earth to suddenly walk to the center of the galaxy. In fact, every winter solstice, from the earth's point of view, the sun seems to be in the center of the galaxy, which is nothing special. It will not cause changes in the earth's gravity, solar radiation and planetary orbits, so this prediction has no scientific basis.

Lie 5: Nibiru planet hits the earth.

NASA: If there was a collision planet, it should have been discovered 10 years ago.

Due to the deep feelings of the disaster site and the mystery of Mayan civilization, some viewers began to believe the story in the film. They logged on major websites and left messages accusing NASA of hiding the truth that Nibiru, the tenth largest planet, was about to collide with the earth.

165438+1October 9, NASA was forced to publicly declare that the doomsday advertised in "20 12" did not exist. In an open letter on NASA's website, scientists said: "The propaganda in the film is groundless. If the tragedy of the collision between the planet and the earth really happened, astronomers predicted it as early as 10 years ago, and now it is very close to 20 12, 12, 2 1, and we can even observe the planet intuitively with the naked eye. Scientists all over the world know that 20 12 will not be the so-called end of the earth. And it needs to be emphasized that in the past 4 billion years, our planet has always been safe. "

Lie 6: neutrinos heat the core?

Scientist: Movies actually changed ideas.

"20 12" makes neutrinos destroy the earth, which sounds "scientific" because only neutrinos can easily penetrate the ground, while other particles can hardly. So, will neutrinos heat the core? Shen, a professor at the School of Geographical Sciences of Nanjing Normal University and an expert in radiochemistry, said that this is impossible because neutrinos basically do not react with other substances. Well, now we can finally understand the "trick" of the film writer: he stole "neutrinos are easy to be detected underground" and replaced them with "neutrinos can bypass the surface and directly heat the core".

What is the most likely cause of the destruction of the earth?

British media assess various possibilities: environmental damage ranks first.

1. Alien invasion probability: 1%

2. Planet X collision probability: 2%

3. Probability of catastrophic solar activity: 3%

4. The probability of the earth's magnetic pole overturning: 10%

5. Probability of super volcano eruption: 10%

6. Probability of World War III: 15%

7. Probability of terrorist incidents causing a large number of casualties: 20%

8. Probability of peak oil production: 40%

9. Probability of bee colony disappearing: 70%

10. Probability of complete environmental destruction: 70%

Discussion: If the end of the world really comes, how to save mankind?

After watching "20 12", many viewers used their brains to think that there are other ways to save mankind besides building Noah's Ark in the movie.

Dig out the Himalayas: Mount Everest and four other peaks above 8000 meters above sea level have a lot of space to use. The Everest Nature Reserve alone covers an area of over 30,000 square kilometers. It shouldn't be a problem to dig thousands of kilometers of tunnels in such a large scope and space. Just stay for a year or so temporarily, and then come out when the water recedes.

Migrate to the moon or build a large space station: Space migration is not new in science fiction movies. Humans have long had this idea, but it has never been put into practice. It should be feasible to put all your eggs in one basket and concentrate all scientific and technological forces and resources to send all or part of mankind into space to seek survival opportunities.

Building a giant airship: Compared with aircraft such as airplanes, airships have stronger endurance in the air, and the cost and technical requirements are far lower than those of space immigrants. According to each airship 1000 people, 1 000 people can be saved by1000 people. It shouldn't be difficult for Qi Xin to build100000 large airship together.
