“One day in the sky, one year on earth” may really exist. It’s not a rumor. Scientists give an explanation!
Since ancient times, there have been rumors that “one day in the sky, one year on earth.”. Since human beings began to explore the universe, they have discovered many secrets, which have also attracted the attention of the scientific community. There are many secrets in the vast universe. What human beings have discovered is just a few sentences. Moreover, the area of the universe is so large that we can hardly imagine, and the earth is just a grain of sand in the universe.
When exploring space, the first one to land is the moon, because the moon is closest to the earth, which is also one of the preferred planets for us to explore space. And human beings have completed the moon landing plan in the last century, but you know, if you sleep on the moon for a day, how long will it take on the earth? As the saying goes, one day in the sky, one year on earth, myths and legends can not be completely believed. The rotation speed of the earth and the moon are different, and there is tidal gravity. The earth and the moon are locked to each other. Under such a fixed relationship, we may think that the moon has no rotation period. In fact, this is not the case. The moon does not have such autobiography as the earth, but it also has day and night. In February, the last day and night is equivalent to one month on the earth.
One day in the sky, one year on the earth, this is a myth. There was a prophecy. It said that a pregnant woman would be frozen to death by the cold in winter, so at this time, the fisherman came to the sky, and had good wine, good food, singing and dancing. The fisherman lived in the sky for about 8 days. Although he was very happy, he missed his family very much and wanted to return home So the God in the sky brought the fisherman back to the world. But when the fisherman came back to his family, he found that it had been 80 years. This makes the fisherman feel that the happy time is always short and painful.
Perhaps the ancients had an idea for a long time, or they had already explored the universe, but they didn’t record it. What they said about the sky may be stars hundreds of millions of light-years away, one day in the sky and one year on the earth, but they just used a kind of fairy tale to confuse us. It may take a year to reach a light-year distance at the speed of light, but it can be reached in a second on earth. Maybe it’s the origin of a year in the sky.
In 1969, when Apollo landed on the moon, astronaut Armstrong left his own footprints on the moon. This is not known as a small step for human beings, but a big step for human beings. What will happen if mostrong sleeps on the moon for a day? A day is the period of weather rotation. The earth is 24 hours, rotation circle, and the moon, this time for mobile phone is around the earth revolution date. On the other hand, there are about 27.23 days in a day and night on the moon. If the astronauts stay on the moon for such a long time, it is estimated that they will not use enough oxygen and their bodies will be affected by radiation, so it is better not to stay so long.
It looks like immortal life on the moon. If human technology reaches a certain level in the future, maybe we can enjoy this kind of immortal life.
