With the development of science and technology, human beings have been unable to be satisfied with exploring the earth. Instead, they are looking beyond the earth. They are eager to decipher the unknowns of the universe and regard all unknowns as beautiful unknowns.
However, when we initially realized that the universe is so big, compared with the earth, the earth is really small, all kinds of incredible problems emerged in our minds, lingering.
The mystery of the universe has not yet been uncovered, and no one really understands its true face. Can’t help but think of a question, in this vast universe, is human the only intelligent life? Is there the same intelligent life as human beings on other planets?
This question has been puzzling us for a long time, not only us, but also experts, and there has been no clear answer.
Although there are many rumors about extraterrestrial life on the earth, more or less there are traces or clues that have survived to today, this is not an accurate and authoritative proof, and there is no way to prove that there are a group of intelligent life like us. Finally, we have to start from a scientific point of view, and scientists are constantly searching for more powerful evidence.
Theoretically speaking, our idea has always been that the living conditions of intelligent life are the same, which must be inseparable from water, oxygen and sunlight. Like us, these are the necessities we want to survive.
Without these factors, we would not be able to survive. But recently, some scientists have said that life once existed in the earth where we live as far as 19 kilometers underground! 19 kilometers underground, what is a concept?
In general, it is very difficult for life to survive within 10 kilometers underground. Although very few, but there are still relatively special organisms can adapt to such an environment.
However, living 19 kilometers underground, for life, it needs to bear great pressure and extremely high temperature. What a tenacious creature to survive in such a place?
Therefore, human beings began to examine whether they made mistakes in the process of research. For example, the direction for human beings to search for extraterrestrial life is to give priority to whether there is a planet with oxygen and water resources. If the environment of this planet is far from that of the earth, then human beings will hardly waste time exploring this planet.
Maybe that’s why humans have missed out on planets where life might exist. Scientists’ simulation experiments have also brought unprecedented answers to human beings.
Scientists specially found a suitable environment for this experiment, simulating the atmosphere oxygen and the environment rich in water resources on earth.
However, long time experiments as like as two peas, scientists have not discovered any possibility of life. Can it show that even if a planet is almost the same as the earth’s environment, it will not necessarily breed new life. Is the direction of human exploration wrong?
If you think about it carefully, we can find such a “super earth” with similar environment to the earth in the familiar planets. So how many in the galaxy? Is there a planet beyond the Milky way that we don’t know but is more suitable for life reproduction?
No one can answer this question, and the scientific community is at a loss. If human beings want to explore further distance, they need the assistance of science and technology, but the ability of science and technology is limited, and human beings can only rely on imagination and reasoning. After all, truth is born after a hundred question marks.
