Outer space has a source of life, it’s a real shame. On September 23, 2022, the Japanese Aviation Research Institute published an article in the American scientific journal . Their detector Hayabusa II detected the existence of liquid water in the sand and stone samples collected by the asteroid Dragon Palace. What does this mean?
Why do scientists first look at whether there is water or not? What is the close relationship between water and the birth of life? Press and hold for three seconds, and the director will find out with everyone. It is worth noting that the water discovered by Hayabusa II this time exists in the crystals. In previous detections, we inferred many times that there might be water, but this is the first time that liquid water has been discovered. Moreover, in the liquid water found, it contains salt and detectable existence. We all know that water is the source of life and is one of the necessary conditions for the existence of living things.
On our earth, whether it is a high-level species, a single-celled organism, or fungi or microorganism, their existence is inseparable from liquid water. You may not agree, but none of the known forms of life on our earth can exist alone without water. Moreover, we all know that liquid water is composed of two hydrogen atoms and one oxygen atom . Liquid water is found, that is, there is oxygen , and oxygen is also one of the conditions for the existence of organisms, increasing the possibility of life.
On the planet in outer space, water is so precious and rare, so where does the water on Earth come from? In the vast universe, most celestial bodies are composed of gas, more than 99% of the elements are composed of hydrogen and helium . The earth, which also has rocks, soil, and water, is destined to be unique when it is born, and 71% of the surface is composed of water.
So where does this water on the earth come from? At present, there are two main views on the source of earth water. One believes that there is water on the earth itself. They believe that when the earth is formed, hydrogen atoms and oxygen atoms form water under certain conditions. But some people immediately refuted that there was no atmosphere at the beginning of the formation of the earth, and the temperature was very high, and even if there was water, it would evaporate immediately. But their supporters have come up with evidence, a spinel peridot, also known as Lynwood stone, which is widely present in our crust.
Scientists have detected this stone. The content of water molecules in the stone is relatively high. Among the 400 to 600 kilometers from the surface, there are 15,000 water molecules in the 1 million crystal molecules in the wood stone. Moreover, the reserves of wood stone are huge. According to speculation, the content of water molecules in the existing wood stone on Earth is more than three times the total amount of water present in the earth, including all oceans, lakes, rivers, and water vapor. Another faction believes that the water on Earth comes from the comet of and . They insist that the star brought water and other organic matter when it hits the Earth, forming primitive life. The source of Earth's water and the source of life on Earth have always been the focus of debate among scientists. The rock samples brought back by Japan's Hayabusa II will provide more evidence for this debate.
In fact, as early as June this year, Hayabusa II was still detecting asteroid rock samples and found more than 20 kinds of amino acid . As we all know, amino acids are the basic unit that constitutes the protein . In other words, there is a high possibility that living matter exists on asteroids, which also caused widespread heated discussions about the origin of life on Earth at that time. There are also two schools of view on the origin of life on Earth. One is that life on Earth is bred from our local area.
At the beginning of the formation of Earth City, the natural environment was not very stable, and living substances, such as amino acids, were formed under certain extreme conditions. Later, the natural geographical environment of the earth became stable, and at the appropriate temperature, life began to evolve and reproduce. Moreover, the locals put forward the most powerful rebuttal that if the earth could not give birth to life. So, why can an asteroid whose conditions are not as good as the Earth in all aspects?
Another faction believes that life originates from outer space, and we are just aliens, temporarily living on the earth.As for how we came from, it has become a problem. Some cultural relics unearthed from Atlantis, Sanxingdui, and Mayan civilizations seem to indicate that another form of civilization exists more advanced than human civilization. Many stone carvings record people coming to Earth on spaceships. The journey of human civilization to find the roots is still a long time to go.
