What is alien life, and what is the ultimate evolutionary goal of smart life?

Many netizens consult this question. This is a very brain burning and no standard answer. No one has seen the so -called alien life body, and can only be imagined by the appearance of the earth's life. Now spending time and space communication from the concept of the earth's life, start talking about this issue for everyone to discuss and share.

General understanding of the appearance of life

Earth's life body mainly refers to organisms, including microorganisms, plants, animals. These life body has its own ability to reproduce, metabolism, growth and development, genetic mutation, old age and death, and reaction to stimulation.

These organisms are bred and evolved based on the earth's environment, and carbon -based creatures are based on carbon elements, so they are also called carbon -based life. Therefore, life is a special phenomenon on the earth, which is different from any other organic matter and inorganic objects.

But the problem is that in the universe, the earth is just a very ordinary and special existence. The cosmic environment is very different. The life body that bred and evolved in other environments can be said to be different from the life of the earth, even not carbon carbon Base life.

For example, some scientists believe that there may be a certain life on Tus 6, but the atmosphere of Tuwei Liu is mainly nitrogen, with almost no oxygen, and the surface has liquid lakes, but it is not a molecules composed of hydrogen and oxidation, but a liquid methane methane, but a liquid methane methane, but a liquid methane methane. The surface temperature is -179 ° C.

In this environment, if there is life in methane lakes, it is definitely not carbon -based life, but alkyl life that rely on adsorption of methane.

Outside of the solar system, the environment of the planet is even more attitude, so there may be a variety of life forms. Many people think that there may be silicon -based life, phosphorus life, boron -based life, sulfur life, and so on. The appearance of these lives may be completely unexpected, and it is completely different from the life of the earth. As for the specific appearance, we are not even imagined now.

Some studies believe that carbon -based life is the best form of life and stability, insufficient thermal stability and chemical stability of other substances such as silicon -based, and it is difficult to form complex and changeable organic groups. The solvents are completely damaged, and common water and ammonia solvents cannot be the carrier of these lives, so this life is extremely difficult to form.

This may be just a one -sided conclusion that is limited to the earth's environment. Today we do not discuss such specific professional issues. Assuming that there are any forms of out -of -earth life exist, then it is necessary to determine whether the life body must have at least several conditions: to be able to reproduce and generate metabolism and growth, react under external stimuli, and can change, alienate and evolve Essence

To become a wise creature, life body needs to evolve awareness, including self -awareness, memory and logical thinking. This is a commonality of all wisdom life in the universe. With a wise life, technology can develop technology, can create a cosmic civilization from low to advanced, and to explore and colonize deep space.

The brief history of the evolution of the Earth's life is: Scientific Investigation has discovered life 3.7 billion years ago, which is just a very low -level microorganism ~ Blue Smals; until 540 million years ago A tangible way appears, at this time, life began to move from low -level to advanced; while more advanced mammals only appeared more than 100 million years ago, and more and more smart long animals appeared more than 50 million years ago. Thousands of years ago, the history of human civilization was only thousands of years, and the history of science was only hundreds of years.

The age of the universe is 13.8 billion years old. There may be a life body that is much earlier than the earth, or there may be a life body later than the earth. There are all forms at different stages of the life of the earth. There are both low -level lives and civilizations, as well as intermediate and senior life and civilization.

From the perspective of creating different lives according to different environments, alien life can only be diverse. Some are like the life of the earth, relying on water and oxygen to survive. In this way, the temperature of the planet is required to be appropriate to keep liquid water as the standard. This is the so -called livable band planet recognized by humans. Of course, like Tusiu, there may be life that tolerate extremely low temperature and no need for oxygen and water.

There may still be a living body with extremely high temperature tolerance, which may dance in the fire. These life forms that are completely different from the living conditions of the earth are one dead end to the earth, because the air and water on the earth, and the temperature are extremely fatal poison for them.

Human final evolution direction

Human beings have developed to the advanced form of life, can constantly understand the natural laws of the universe, and use these cognitive transformation worlds to obtain better living space. But at this time, human beings have not separated from the most primitive stage of life, that is, exist in a tangible physical way.

On the earth, life has a life span, and as the only human life on the earth, survive in the way of physical existence, which is shorter than the cosmic celestial body, only about 100 Earth years. The degree of civilization of the universe is now calculated based on the Caldashev index recognized by the scientific community.

Since ancient times, human beings have been seeking long -lasting cheats, but in ancient times, they have adopted the methods of ignorance and superstition. For example, fantasy such as seeking immortal alchemy, not only useless, but also send these people to Naihe Bridge faster. After the enlightenment of scientific and technological civilization, through the understanding of natural laws, health and longevity gradually began to incorporate the orbit that conforms to the laws of nature.

Through anatomy, cytology, and genetics in modern science, people have become more and more deeply understanding their bodies, so as to achieve longevity goals through eating, drinking, drinking, food, food, and transportation; Pharmaceutical, immunity and genetic treatment have controlled and cured diseases that endanger human life, and have greatly guaranteed the improvement of life.

However, the natural law of the old and sick is the natural law of the flesh. No matter how hard it is, it is just the delay and repair of the aging process of the human body. In the end It is very limited, and scientific research believes that the highest physical life of people is about 150 years old.

This life seems to have a long life on the planet, but it is not suitable for the interstellar travel that is not suitable for human civilization in the future, but it is not suitable for the future of interstellar travel that is not suitable for human civilization. Therefore, the forefront scientists have begun to transfer their attention to consciousness preservation and consciousness.

Modern science has long proved that consciousness is the main sign of human beings. A person has no consciousness. Even if the body is intact, it is just a walking dead, and even the walking dead. Such as the brain death, plant man, and mental patient, even if they are "alive", they are "dead"; and people who are paralyzed in the whole body, even if they die, as long as their brains are alive, they are still alive.

The late scientist Hawking, the whole body was paralyzed, only the eyes and two fingers could move, and he survived on the wheelchair for decades, but he relied on the smart brain to achieve the world's attention with the cooperation of artificial intelligence.

Therefore, modern science believes that as long as people's consciousness can remain, even if the body is dead, they can survive in a conscious way. As a result, modern cutting -edge science has begun to study the topic of consciousness preservation and transfer, and has made certain progress. Such as Google's conscious transfer research, Musk's brain -machine interface, Russian tycoon Avanti plan, etc., all try to retain people's consciousness.

These studies have threatened to succeed in the next thirty or forty years. Therefore, I think that the highest evolution of wisdom life is the invisible avenue and exist in a conscious or energy way.

A combination of consciousness with the body or clone body can control and transform the world. How long can consciousness "live", there is no conclusion yet, but at least more longer than the flesh. Because almost all normal people die, consciousness is good. It is just that consciousness cannot be separated from the human brain and exists independently, so the consciousness of people has dissipated.

The process of any civilization upgrade will be accompanied by the evolution and upgrade of the life body itself

Human civilization has reached level 0.73, and has not yet achieved first -level civilization. It has begun to explore the way human existence of human beings in the future. Although some institutions threatened to achieve great progress, it may not be able to achieve great progress. In 5000 years, I believe it can always be successful.

Some scientists believe that human civilization will reach the first level in the next 200 years and the level of secondary civilization in about 5000 years. This means that human beings may exist in consciousness before realizing second -level civilization. Consciousness is intangible, perhaps some kind of energy, that is, human beings will exist in consciousness and energy in the future.

When it comes to the second level of civilization, the civilized body may fly out of its own star system and conduct interstellar exploration and immigration. Only at the same time as the civilization is upgraded, the wisdom itself has evolved and upgraded the same, and eventually existed in an invisible way of conscious energy, can we adapt to the requirements of long Starway travel on life, and greatly reduce the star ship.

Therefore, I think that leaving a tangible entity and an intangible way of conscious energy is the ultimate evolution of each smart life body. In other words, whether it is Earth humans or alien wisdom life, as long as it reaches a secondary civilization, no matter what the previous tangible appearance is, it will move towards the invisible conscious energy form.

Therefore, I think the future of many science fiction literature and film and television is nonsense. These science fiction literature and film and television only focus on the continuous development of science and technology equipment, and at all the evolution of the civilization and wisdom. Civilization and life body still exist in a clumsy tangible entity, but with simple imagination, various alien civilized body imitates the plant animals of the earth, which is strange.

Now human beings need to eat grain grains, enjoy a large amount of material consumption such as air and water, in order to transform such a little poor energy through the complex physical chemical system in the body and maintain their own life signs. This is a great waste, and the invisible form of life does not need these.

The only need for the wisdom of conscious energy is the supplement to pure energy. This energy is inexhaustible in the universe. The transformation of any substance and so on. Such a wisdom body has already understood very deep natural laws. As long as there is sufficient energy, you can create almost all substances.

These wisdom can also be easily connected to the Internet. For example, the consciousness of all mankind is combined into a huge network to form a huge and efficient polymer, which can compete with huge universe disasters and solve the problem of complex complex imagination.

Therefore, the high -level civilized interstellar ship does not need to set the living space and facilities for the smart life body to eat and drink, and no need to carry water, food, utensils and other supplies. The size or even smaller spacecraft can load many wisdom bodies that exist with conscious energy. When you reach the third -level civilization of the universe, maybe there is no need for a spacecraft, and the wisdom itself can be transmitted in a conscious energy wave. It shuttles between galaxies and galaxies, free and easy.

Now, humans have been looking for hundreds of years, have not found any signs of life outside the earth, and have not found overseas civilization. This is because human observation levels are still very low now. The best telescope on the earth, and the planets and satellites within the solar system cannot be seen, let alone planets outside the solar system.

Therefore, human beings do not find extraterrestrial life and civilization, which does not mean that there is no existence of external life and civilization. But it is almost certain that in the scope we have observed, there is no high -level external civilization, which is at least two or more external civilizations. Because if so, these civilizations will transform their stars, causing abnormal changes in the light of the star, and humans can observe it.

Human beings have observed millions of stars around them and have not found these changes. Therefore, there are no scientists who are rumors such as flying saucers and aliens that are constantly appearing on the earth. Because according to the current level of human space, don't say that flying out of the solar system is only 12 people with only hundreds of thousands of kilometers.

And even if there are aliens, at least a few light years from us, aliens who can come to the earth must at least have a second -level civilization, that is, these aliens should not exist in a physical way. Maybe sitting on that kind of flying saucer, dumbfounded? This is just that some people imagine ugliness as humans.

Speaking of this today, welcome to discuss, thank you for reading.
