Did humans first take refuge from Venus and come to Earth?

Venus is the planet with the worst conditions in the solar system, and there is no one! But more than half a century ago, people fantasized about Venusians. For example, george adamski, who is good at the fourth kind of contact, claimed to have had contact with Venusians, and traveled around on the other side's spaceship, leaving many photos of Venusians' aircraft carriers, which are said to be taken by george adamski!

However, george adamski is lucky. At present, when the first Soviet probe "Venus IV" successfully learned that Venus conditions landed on Venus, he had already died, so he was not exposed before his death, because Venus is a harsh condition with a surface temperature of 447 degrees and an atmospheric pressure of over 90 degrees. You can't imagine that there will be so-called Venusians under such conditions!

George adamski described the contact event.

Modern Venus is not suitable for living, so can ancient Venus live in people?

Both the Earth and Mars are located in the livable zone of the solar system, while Venus is located at the hot edge. Its distance from the sun is only about 2/3 of the distance between the sun and the earth, and the thermal radiation from the sun is about 3.4 times that of the earth. So even if Venus was livable in those days, life under such conditions would be more sad, because the ambient temperature might be higher!

Is there an era in the history of Venus where people can live? It is estimated that no one will answer this question, but we can infer the conditions of ancient Venus according to some conditions of Venus, such as the following aspects.

Venus orbits the sun for 224.7 days, with a rotation period of 243 days. Some people may think that the last day on Venus lasted more than a year. However, the difference between sidereal day and Solar Day means that this is not the case. Combined with the orbital period of Venus, it takes 1 16.75 earth days for the sun to return to the same point in the sky (from one sunrise to the next). Period of revolution of Venus has 224.7 Earth Days. Divide this number by the number of days and nights of Venus (1 16.75 earth days) to get the number of days of Venus itself in a year, which is about 1.933 days. Therefore, taking one sunrise to another sunrise as the standard of a day, Venus is a year in less than two days. This is completely unsuitable for the evolution of life.

Speculation on the environment of ancient Venus: The Gotha Space Research Institute of NASA established a Venus model to simulate the evolution of Venus. It is believed that ancient Venus maintained a suitable temperature. Isotope detection of Venus' atmosphere found that there was a lot of water in ancient Venus. The simulation also found that the suitable temperature of Venus remained for about 2 billion years.

According to the earth's experience, it took more than two billion years from primitive to the birth of life and then to the emergence of single-cell photosynthetic cyanobacteria. We are not sure about the development speed of life on Venus, so we can only look for cyanobacteria that produce oxygen through photosynthesis on earth.

The surface of modern Venus can only be traced back to 700 million years ago, because these landforms were produced by volcanic activities 700 million years ago, and even many areas are not more than one million years old, so it can be said that the surface of Venus is very young.

Venus' carbon dioxide atmosphere: Venus' carbon dioxide atmosphere exceeds 90 atmospheres, and there are thick sulfuric acid clouds near the surface of Venus. How this came about has always been a mystery, but there are several speculations:

Venus has no magnetic field, and water vapor is more easily bombarded by the solar wind and dissociated into hydrogen and oxygen. Hydrogen is easy to escape, leaving a lot of oxygen, which combines with carbon on the surface of Venus to form carbon dioxide. Without Venus in the ocean, there is no water vapor cycle and carbonate-silicate cycle. In the later period, a large amount of carbon dioxide emitted by volcanoes could not re-enter the ocean and was solidified by crustaceans, so the carbon dioxide level of Venus became higher and higher, and finally Venus successfully blew itself up! Due to many factors, the livable time of Venus may not be enough to breed life, and the conditions will deteriorate in the later period. It is even more impossible for Venus to breed life after the greenhouse effect of carbon dioxide is out of control. However, the current conditions of Venus have existed for hundreds of millions of years, or even longer.

Since Venus never gave birth to life, why did the Mayans know so much about Venus?

Among the calendars used by the Mayans, there is a 260-day Zalkin calendar. Many friends think this year is the year of Venus. In fact, as explained above, Venus has a year of 224 days on the earth, and a day and night is 1 16.75 days. In other words, how many suns Venus can rise and fall last year has nothing to do with 260 and a half days, so this is simply an irrelevant question.

Another evidence is that there is a 584-day Venus periodic calendar. This 584-day period is very strange, whether it is revolution or rotation or a multiple of both, but this period is very close to the rendezvous of Venus. The rendezvous period of modern observation of Venus is 583.92 days, and the 584-day period in Mayan calendar is very accurate!

Rendezvous period: The relative positions of the sun, the earth and a planet or the moon circulate for one week, which is called "rendezvous period". Because of their different revolution speeds, this period will be much longer than that of the planets.

This 584-day period is invisible on Venus, but it proves that the Mayans got this accurate rendezvous period by observing it on Earth. Of course, it is understandable to choose Venus, because Venus is the brightest star in the night sky, but we have to say that the Mayans observed Venus really carefully and even recorded the apparent movement period of Venus.

However, the Venus calendar recorded in the Mayan calendar is not a festive event, but related to war and death. Maybe the Mayans thought the bright Venus was really unlucky, so they used it as a calendar for recording unknown events.

The Mayans have disappeared in the jungle of Central America, but we are still lamenting the Maya's diligent pursuit of astronomical knowledge!
