Looking for aliens in the wrong direction, aliens have no trace, completely due to the earth’s climate

Scientists have been looking for traces of aliens, but they have not found anything. People have always doubted whether there are aliens or not. Maybe there are. For some reason, it is difficult for us to find traces of aliens. According to foreign media reports, more and more astronomical observation data and studies recently show that there may be habitable earth and extraterrestrial civilization in the universe. Recently, science and technology has made great progress Scientists have found that perhaps the earth’s climate change has hindered the connection between human beings on earth and alien civilizations. So, what is the relationship between the earth’s climate and aliens?

Human beings have never found any clues about the existence of aliens


Enrique Fermi, a famous physicist and Nobel laureate, put forward the “Fermi paradox”. According to this theory, extraterrestrial civilization exists in the universe and is more advanced than earth civilization. They are advanced enough to complete the interstellar journey in a certain space time and reach a certain place on earth.

But the problem is, so far, humans on earth have never found any clues about the existence of aliens. In the past, American astronomers have studied that there may be hundreds of millions of habitable planets in the Milky way. Recently, they found a rock “super earth” 17 times heavier than the earth, and it has an atmosphere suitable for life.

But why haven’t humans found aliens yet? There are many explanations for this problem. Some people think that Star Trek cannot be realized, while others think that alien civilization has destroyed itself.


Recently, another study of scientists suggests that it may be the earth’s climate change that hinders the connection between human beings on earth and alien civilizations. However, this is not to say that advanced civilizations will self destruct due to the overheating of the biosphere. (it could be, of course).

For every 1% increase in surface heating, the temperature will rise by several degrees Celsius


On the contrary, because stars become brighter as they age, most planets that originally have favorable climates for life also become hotter and less habitable.

Although the sun burned a lot of fuel before the earth was formed, the earth has had a good climate for 4 billion years. Modern science has been able to predict the possible consequences of human emissions of greenhouse gases, so we can now estimate the future warming trend.

According to the prediction of scientific models, every 1% increase in the degree of heating on the earth’s surface will lead to a few degrees Celsius rise in temperature. The surface temperature of the sun has risen by about 4% in the past 500 million years, while the earth’s surface temperature should have risen by about 10 degrees Celsius.


We can simply infer that in the whole history of life, the temperature has almost increased by 100 degrees centigrade, and from this point of view, the temperature has almost increased by 100 degrees centigrade. If this conclusion is correct, then early life will appear on a completely frozen planet.

But there’s liquid water on the surface of the young earth. So why does this happen? The answer is that it’s not just because of the changes in the sun, but because of the evolution of the earth.


Four hundred million years ago, the emergence of terrestrial plants changed the composition of the earth’s atmosphere and the proportion of solar radiation reflected. In addition, there are geological changes, the land rises slowly with time, and volcanic activities also affect the atmosphere and the earth’s reflectance.

The surface temperature has been changing for four billion years

The evolution of Geology and biology usually produces cooling effect, which makes up for the warming effect brought by the aging of the sun to a certain extent. Such compensation is too slow or too fast each time, but liquid water has never disappeared from the surface since the birth of life on earth.


Incredibly, mild climate change on the earth’s surface has continued for four billion years. Observations have developed the Gaia hypothesis that complex biosphere can spontaneously regulate the earth’s environment.

However, Gaia hypothesis also lacks a reliable mechanism, and there is a problem that the complex biosphere exists on the premise of a relatively stable environment.


This theory is not without reason. Everything is regular. Even if alien technology is developing, there will not be a day of immortality and destruction in the end. Coupled with the unstable climate around the earth, which affects the reception of signals, it is likely to lose contact with aliens.
