Is the forecast of 20 12 true or false?

20 12 will we have a burning sun? Scientists predict that solar activity will reach an unprecedented peak, that is, in the solar cycle of 20 1 1, there will be the most sunspots and the strongest solar activity. So we can foresee that there will be a lot of solar activity at that time. Some scientists predict that solarmax in the 24th solar cycle (20 1 1-20 12) may release more energy than the previous peak in 2002-2003. Solar physicists are excited about the upcoming solar activities, and some new scientific prediction methods and monitoring tools have been put into use. However, should we really worry about the "end of the world" of 20 12? One of the many doomsday scenarios predicted by humans before will be the "doomsday" predicted by Maya in 20 12 years. When the fifth solar year of Maya ended, it was inevitable that the sun disappeared and the earth began to shake. According to the Mayan prophecy, the solar year has only five cycles. Once the sun goes through five cycles, the earth will be destroyed. The fifth solar year began in 3 1 13 BC, and ended around 20 12 A.D. and 5 125 A.D. in the Mayan period. In fact, this Mayan prediction scene has a certain scientific basis, at least indicating that solar activity has an impact on human beings. Scientists have found that some possible relationships can be found between the solar cycle of 20 1 1 and the time period proposed according to the Mayan calendar, but these relationships are only related to astronomical observation. The Mayans did observe some activities of the sun. In addition, religious classics (such as the Bible) say: We are about to usher in the judgment day, full of fire and sulfur. Therefore, it seems that we are welcoming the day of 20 12 12 2 1, and the nearest star will bring us unimaginable heat! However, before we jump to conclusions, let's take a step back and consider it comprehensively. Like most other scenarios that predict the "end of the world" in 20 12, the huge solar flare that the sun sends out and destroys the earth is very attractive to those who predict the omen and those who don't understand scientific knowledge. But from the study of solar flare effect, we can see what happened to the sun and what will happen to the earth. In fact, our earth is in good condition. Solar flare is one of the most violent solar activities. Bright spots suddenly appear on the surface of the sun, and its life span is only a few minutes to dozens of minutes. Brightness rises rapidly and drops slowly. Once a solar flare happens, it is an earth-shattering explosion on the surface of the sun. The energy released by flare is equivalent to the total energy of 6.5438+million to 6.5438+million strong volcanic eruptions, or equivalent to the explosion of tens of billions of 100-ton hydrogen bombs; And a large flare burst can release huge energy in 120 minutes. In addition to the local sudden brightness of the sun, the flare is mainly manifested in the sudden increase of radiation flux from radio band to X-ray; Flares emit a wide range of radiation, including ultraviolet rays, X-rays and gamma rays, infrared rays and radio emissions, shock waves and high-energy particle streams, and even cosmic rays with extremely high energy. When a flare breaks out, when a large number of high-energy particles reach the earth orbit, it will seriously endanger the safety of astronauts and instruments in the spacecraft. When the flare radiation approaches the earth, it will collide violently with atmospheric molecules, destroying the ionosphere and making it lose the function of reflecting radio waves. Radio communication, especially short-wave communication, as well as television and broadcasting, will be disturbed or even interrupted. The high-energy charged particle stream emitted by flare interacts with the upper atmosphere of the earth, producing auroras, disturbing the earth's magnetic field and producing magnetic storms. In addition, flares have direct or indirect effects on meteorology and hydrology to varying degrees. But there will be no exaggerated effects and scenes such as geomagnetic inversion and skyfire. Therefore, with the increasing attention to the detection and prediction of solar flares, human beings are gradually uncovering the mystery of solar flares and gradually understanding the impact of solar flares on the earth. Scientists say that the sun has been in a highly radioactive environment, and the cycle of solar activity is about 1 1 year. The latest observation data show that a medium-sized magnetic junction phenomenon has appeared on the surface of the sun recently. This may indicate the arrival of a new solar activity cycle, but due to the unpredictability of sunspot activity, 2008 may also be a relatively "quiet" year of solar activity. For solarmax of 20 1 1-20 12, scientists believe that solar flares do not have the ability to destroy the earth. After some data simulation and research on the earth's atmospheric environment, the solar flare in 20 12 years will only cause a devastating blow to the earth's communication system, and will not do great harm to the earth itself.
