Does life need oxygen to survive? Maybe there are creatures in the sun, whose temperature is as high as tens of thousands of degrees!

Today’s science and technology is more and more developed. Exploring other planets in the universe has become a new goal for human beings. Human beings have always been preparing for a rainy day. Just like some science fiction films, if one day human beings encounter natural ecological disasters such as global warming, volcanic eruption and earthquake caused by environmental pollution, they will have to find a new livable planet. How difficult it is to find a planet in the vast universe with enough oxygen and enough water to ensure the survival of human beings. Many netizens can’t help asking: “do you need oxygen to survive?”

Do planets with oxygen have life? Life system

Does the combination have to have water and oxygen?

As we all know, water and oxygen are essential factors for the existence of life on earth. After being absorbed by organisms, the oxygen contained in the air is replaced in the body and discharged out of the body into exhaust gas, ensuring the fresh activity of biological cells. In addition, the water resources in the earth can maintain the cells in the organism and promote metabolism. In the eyes of many people, all living things on earth are inseparable from water and oxygen, which are essential elements of life. Is that really the case?

In theory, that’s the truth. We live in the earth, and all life is based on oxygen and water. In the process of human exploration of the universe, we often compare the earth with other planets. If other planets are similar to the earth and have a high degree of similarity, it means that the probability of its existence of life is particularly high, otherwise it will be very small. From this level, we can see that the concept of life existence in theory is very narrow. For example, does an apple tree have to be an apple? In the eyes of the older generation, apple trees have been bearing apples since ancient times. However, with the development of modern science and technology, through the “grafting” planting technology, the fruits of today’s apple trees are not apples, they may also be other species.

A related scientist said: “in the universe, not all planets have the necessary elements of carbon based life, such as oxygen and water, like the earth. The life in these planets may be amino life, relying on the oxidation of ammonia or iron to convert silicon-based life. Of course, another kind of life may use nuclear energy as energy to carry out life activities. “

Is there extraterrestrial life on planets other than the earth? What do they live on?

In the relevant scientific research, scientists found that there were many cellular organisms in the universe more than 4 billion years ago. Scientific researchers from the University of California in the United States conducted in-depth analysis and Research on a fossil unearthed in Australia. In the process of detection, scientists found that these fossils existed in the earth for at least 3.4 billion years. What are these fossils? Scientists are not sure, but according to the tested ingredients, scientists have made a bold guess that these creatures may have floated to the earth from extraterrestrial, and survived in the earth. It can be seen that there were all kinds of creatures in the universe billions of years ago.

1. Hydrogen and helium in Jupiter are the basis of life support for organisms, and may float in the gaseous layer

Some netizens can’t help asking: “if there is life in extraterrestrial, what do they rely on to maintain their life?” In a study of life on earth, it is found that oxygen is indeed conducive to the existence of life. However, oxygen is not common in the universe, accounting for only 0.1% of the mass of the universe, which means that the most common gas elements in the universe are hydrogen and helium. Jupiter, the largest planet in the solar system, has an atmosphere full of hydrogen and helium.

In order to find out whether these two gases can support life, planetary research scientists at MIT chose a kind of earth organism that can survive in anaerobic conditions. This organism is known as “E. coli”, which is the most common bacteria in the intestines of human beings. In order to cultivate its survival rate, scientists specially searched for it There are two kinds of sealed bottles. One of the sealed bottles was then filled with hydrogen and the other with helium. Every few hours, scientists remove E. coli to see if they can survive. According to the experimental report, E. coli can survive better in a sealed state.

It’s not surprising that the findings could help scientists find a wider range of habitats for life on different habitable planets. If the outer layer of Jupiter is gaseous without a solid surface, then there may be some floating organisms that rely on hydrogen and helium to support their life in this gaseous planet. These organisms, like fish and other marine organisms in the ocean, constantly float and swim in the gaseous atmosphere of Jupiter to maintain their survival.

There is life in the “regional star”. There is continental phosphine in the atmosphere. The highly toxic gas may be biological metabolites

Venus is known as the “regional star”, it is the worst planet in the whole solar system. In the 1950s, the famous science fiction writer Asimov wrote a novel about the existence of life in science fiction Venus. And all along, people believe that Venus is so similar to the earth that there should be life like the earth. However, the surface temperature of Venus is so high that it will not drop even at night. Sulfuric acid rain may fall in Venus at any time. The atmosphere of Venus contains more than 90% carbon dioxide, which is tens of times higher than that of the earth. Although it is a “regional star”, in the research of astrobiology, it is found that some microorganisms can live in the atmosphere of Venus. Phosphine is a highly toxic gas, which is easy to be consumed by some oxidizing substances in the atmosphere. According to this characteristic, scientists have made a bold guess that there must be a mechanism of phosphine constantly generated in Venus, and this element has a certain content It may be the product of biological metabolism.

There used to be liquid water on Mars, which contains a lot of xenon, which is the fundamental element for the maintenance of life

From the perspective of external volume, Mars is smaller than the earth. That’s why Mars is relatively small in gravity, and its gravity is not as big as the earth. Although there are many places similar to the earth on Mars, its ecological environment is very bad, the four seasons are not clear, and it often blows sandstorms. In the Mars detector, scientists found that there is a large amount of xenon in Mars, and there are many uranium and thorium components in the soil surface of Mars. Through the comparative analysis of the photos sent out by the Mars detector, scientists also found that Mars is almost composed of red rocks. In the rock exploration analysis, scientists found evidence of the existence of liquid water. That is to say, in such a harsh Martian environment, there used to be organisms. These organisms relied on liquid water and other Martian gases to support their life. These organisms may have had a nuclear war, which led to the destruction of these organisms. All life on Mars disappeared and became Gobi Desert everywhere.

There may also be life in the sun – using solar energy to sustain life

In human exploration of the universe, we often detect other planets in the universe by sending detectors. However, for the sun, we are helpless. As the only star in the galaxy, it is almost the most ideal sphere interwoven with thermal plasma and magnetic field. The sun is like space, releasing heat and light. However, our understanding of the high temperature of the sun is limited, or even unable to get close to it. Some researchers believe that there may be life in the sun, which mainly depends on solar energy for life. After obtaining this high-energy supplement, we can evolve wisdom and develop into intelligent civilization. Some scientists even call the latent life in the sun “nuclear life”. Then this kind of “nuclear life” may surpass stars or any living body in the universe, and they may also have a very powerful deterrent force. At the same time, they can use the stellar energy of their hosts to survive and reproduce.

A netizen’s brain hole is wide open: “the life bodies stored in the sun may be powerful alien creatures, and their body temperature can be as high as tens of thousands of degrees.”. The light of the sun is very strong. The other side of the sun has completely changed people’s view of flares. As a sphere, the sun is 25 times larger than other planets. Every time the sun’s activities are different, it is likely that alien creatures are causing trouble. Moreover, in many science fiction novels, sunspots and other activities are recorded to give the earth through the movement of sunspots The ball has brought all kinds of disasters. Of course, this kind of science fiction only appears in novels. We don’t know whether it really exists or not. Assuming that there are no aliens in the sun, there may still be a very powerful creature. This powerful creature, a fireball at the jet, is enough to destroy the whole earth.

How long can the life in the alien survive? Can you live forever?

If there are organisms that do not rely on oxygen and water as the main carrier, their lives may span from a few seconds to millions of years. For example, some of them may survive for 1 million years on carbon, and others may survive for 2 million years on silicon. Those living on nuclear energy or solar energy may live for only a few seconds, of course The life span of some extraterrestrial creatures is only a conjecture. After all, our current science and technology are still limited.

The carriers of life in the universe are complex and diverse, even they are far beyond our science and technology. We can’t explore and study them. This advanced carrier of life will certainly exceed our cognition. Let’s make a bold guess. If human beings are the real overlord of the earth, there will be other planets in the universe that give birth to life, and these life will be the most important Advanced intelligent life carrier. What is the advanced level?

For example, if the advanced degree of robots is multiplied, then one day the advanced life carriers in the universe will crack the codes of robots, turn them into their own carriers, be controlled by them, and make the complex world full of the vitality of robots. The whole universe will be a super civilization. Today, we are looking for clues about alien life through the bottom of a wine bottle Even so, we still can’t guess the advanced life carrier in the universe and can’t identify it. After all, our technology level is limited now. Perhaps in the next few decades, millions of years, human beings will be able to find the best way to ultimately explore the carrier of life in the universe, and then find a livable planet for human beings.
