Although the environment is so bad, Mars is also one of the closer planets that humans can explore on earth. At the same time, exploring the causes of climate change on Mars is also of certain significance for learning lessons and maintaining the ecological situation of the earth, so people have always maintained great enthusiasm for Mars research.
And according to scientific research, the climate of Mars was very similar to that of the Earth 4 billion years ago. There is probably a dense atmosphere and a warm environment, rivers, lakes or oceans, and even life. So many people think that life in the solar system may have originated from Mars, and this gorgeous red planet may be the original birthplace of life. Because at the same time, when Mars has the conditions to start the process of life, the earth does not.
Some people even began to boldly put forward such a guess: perhaps a long time ago, there was a human civilization on Mars, and it was still highly civilized, but it was immediately destroyed by a total nuclear war or a nuclear strike by aliens on another planet, leading to the complete extinction of Martian civilization. As a result, great changes have taken place in the whole of Mars, becoming desolate and silent.
He further believes that the red color on Mars may come from natural thermonuclear explosions. These shocking grand conjectures are certainly followed by many science lovers, and they continue to provide evidence for completing logical self-consistency.
The saying that "Mars once had a civilization, but it was destroyed by nuclear war" is widely circulated, and countless fantasy stories have been derived from it. But scientists shook their heads at this statement. They don't think such a thing can happen. Scientists have also produced two conclusive evidences to tell you the answer to this question.
So far, humans have sent many probes to Mars. The data sent back by these probes show that Mars did have an environment suitable for life 4 billion years ago, but the environment on Mars began to deteriorate rapidly 3.7 billion years ago, and then it was no longer suitable for life.
Judging from the history of civilization development on earth, life on earth has evolved for more than 4 billion years before a decent civilization was finally born. However, Mars has only been suitable for life for hundreds of millions of years, and it is impossible to breed mature life, let alone a more advanced civilization.
There is some other evidence about the study of life on Mars. Someone has found an underground liquid lake on Mars, and it is speculated that the reservoir under Mars is likely to have a very rich storage capacity, even comparable to the capacity of the earth. In addition, some scientists found seven strange caves on Mars. They believe that if primitive life really exists on Mars, but they have no ability to work, these are the natural structures on Mars that can provide them with protection.
In other words, all kinds of evidence show that even if there may have been life on ancient Mars, it is just a simple life without evolution. As for the oceans on Mars, the latest theory of Tim Parker, who works for NASA, is that there may be oceans on Mars, but in geological history, it only existed for a short time. His analysis also dealt a heavy blow to the view that there are higher organisms on this wild red planet.
Of the eight planets, only Mars has no magnetic field, but relies on a strong magnetic field in the earth's crust. However, there was a magnetic field on Mars billions of years ago, but the volume of Mars itself is only about one seventh of that of the earth, which is not enough to keep the magnetic field running at high temperature for a long time, so it gradually lost its own magnetic field and led to environmental deterioration.
The magnetic field can protect the earth from the direct damage of cosmic radiation and solar storms, so after Mars lost its magnetic field, the solar storms intensified and the atmosphere on Mars became thinner and thinner. Without a dense atmosphere, liquid water can no longer exist on the surface of Mars, so lakes, rivers and oceans that once existed will soon disappear. If we go on like this step by step, even microorganisms will hardly survive in the final environment.
This is scientists' reasonable speculation about the reasons for the deterioration of the environment on Mars: the insufficient size of the planet leads to the decrease of the core temperature, which destroys the operation of the magnetic field, leads to the attack of solar storms, the disappearance of water sources and the damage of life. Three billion years ago, Mars stopped all geological activities. However, if the deterioration is due to nuclear weapons, according to calculations, even if all the nuclear weapons that can be developed on earth are transported to Mars and then detonated, the explosive force can only cause some damage to the surface of Mars at most, and it is impossible to destroy the core of Mars.
In the last reason, we say that it is difficult for Mars to develop a civilization beyond the present situation of the earth. Therefore, even if we take 10,000 steps back, there really is a high civilization like the earth on ancient Mars, and the destruction of civilization will not be caused by nuclear war. Because even if they resist the war and desperately use all nuclear weapons to attack the enemy, their destructive power is far from enough. As for the deadly nuclear attack of alien civilization, it is hard for us to imagine any strange civilization with such a powerful force, which is still unknown to mankind.
The above two evidences are clear enough for scientists to overthrow the theory of destroying Mars by nuclear war. However, despite this, scientists still believe that in the long run, Mars is still a planet for people to move to, and its ancient and unknown story is worth exploring and excavating again and again.
The infinite fantasy and yearning for space is one of the reasons why science and technology have made such progress, and the breakthrough in this field has gone beyond the scope of anthropology itself. For a long time, mankind has always had a great desire to embrace other splendid civilizations.
In any case, the more in-depth study, the more I feel that it is wonderful to have a highly civilized livable planet, the earth, in a long universe full of strange and desolate planets. Although it is still in its golden age, nothing is eternal, and everyone should learn to respect life.
