Today is December 21, 2012. I couldn’t sleep in the morning. It was snowing outside and the sky in the west was red. It seemed that there was an abnormality in the sky.

There may be a "celestial overlap" in 2012. This "celestial overlapping" phenomenon occurs once every 26,000 years. According to the prediction of "celestial overlap", the sun's path in the sky will pass through the center of the Milky Way. Many people worry that this misalignment of celestial bodies will put the earth under the pull of more powerful unknown cosmic forces, which will accelerate the destruction of the earth. Either it may cause the Earth's poles to swap, or it may form a huge black hole at the center of the Milky Way. The Milky Way is extremely vast, with a diameter of up to 100,000 light-years (one light-year is equivalent to 10 trillion kilometers). This means that sending a text message from one end of the Milky Way to the other end, even at a speed of 300,000 kilometers per second, would take 100,000 years to receive. The sun is just an ordinary star among the 200 billion stars in the Milky Way. It is very far away from the center of the Milky Way, about 33,000 light-years away. The sun rotates around the center of the Milky Way at a speed of 250 kilometers per second, with a revolution of about 2.5 seconds. It has been running very regularly for billions of years, and it is impossible for it to pass through the center of the Milky Way in its path in the sky, just like the earth orbits the sun about 4.6 billion times, and it will not go to the sun.
