    There may be many, but the end is to be found.

    There is no way to answer such a question at present, because human beings only know that there are only civilizations created by humans in the universe, and they have not yet discovered the existence of civilizations on other planets. Of course, this is not to say that there are no other civilizations in the universe, but that the universe is so large that it is far beyond the current limits of human observation.

    You must know that in our galaxy alone, there may be more than 100 billion alien worlds, of which the number of planets that are qualified to harbor life may reach billions. Although the emergence of life depends on many conditions, considering that there are so many worlds, there are always some like the earth that meet various conditions that allow life to evolve, even intelligent life. Therefore, it is difficult to imagine that there are no other civilizations in the universe, but we do not have the ability to discover them yet.

    After all, we have only been in the space age for a few decades, and astronomical observation technology is still relatively backward.

    In response, astronomer Drake proposed the Drake equation to estimate the number of possible extraterrestrial civilizations in the Milky Way, which takes into account factors such as the rate of star formation, the number of habitable planets, and the number of planets with life. It is estimated that the number of civilizations in the galaxy may be more than 1,000. Due to the limitations of current technology, humans have not yet discovered them.

    Since there may be many civilizations in the universe, how do we find them?

    The most important way to do this is to make progress in observation technology, and to build more powerful telescopes, not only with the current telescopes. In addition, there are some special methods that can be used to search for extraterrestrial civilizations.

    Although we can't see the surface of exoplanets directly, we can tell if there is intelligent life living there by some spectral information. If extraterrestrial civilizations also develop into the space age, they will also launch satellites into space. When their home planet is surrounded by an extremely large number of moons, this blocks out a small portion of the light from their host star.

    By observing this anomaly, it is expected that extraterrestrial civilizations will be discovered.

    The universe is vast, there will definitely be other civilizations, and it is impossible to have only one advanced life like humans, but because it is too far away, it has not yet been discovered.

    No. Because the birth of life is very difficult, and it takes a long time to develop into a civilization, there should be no other civilization in the universe.

    It has not yet been discovered, but it does not mean that there is none, and this needs to be further explored and studied.

    Civilization has a contradiction in development. On the one hand, higher technology brings greater personal destructive power. The greater destructive power of the individual leads to the collapse of human group cooperation, and once human beings lose the ability to cooperate in groups, science and technology cannot be fully improved.

    The current level of human civilization is only one step away from stepping into the era of space civilization, that is, the era of space self-development after mankind has conquered controlled hydrogen fusion technology and anti-gravity flight technology. At that time, human spacecraft could carry magnetic fields without being damaged by cosmic radiation, human beings could live in outer space for generations, human beings mined in the asteroid belt, smelted in space, used additive technology to continuously expand spacecraft, could collect deuterium fuel on the surface of Jupiter or the sun, and could have an equal dialogue with extraterrestrial civilizations.

    You can go out of the solar system to find another newer galaxy to build and rule, and you can extend your thoughts and pleasures to hundreds of millions of futures! According to the actual situation, it is impossible for a civilization to exist 100 million years after the birth of the universe, because the stars have not yet formed at that time, so we can only assume, that is, if a civilization continues to develop for tens of billions of years, what kind of horror will such a civilization develop to now? If you want to look at the development speed of human civilization, it took thousands of years from nomadic tribe civilization to feudal civilization, from agricultural civilization to industrial civilization, it took thousands of years, from industrial civilization to the present, only a few hundred years, the speed of change is getting faster and faster, and it is difficult to guarantee that the next few hundred years will not enter the quantum age, or the interstellar age.

    Tens of billions of years have long been beyond the scope of imagination, their form of civilization may be dominated by independent individuals, or in other words, they have already surpassed civilization, each individual is immortal, they have no entity, some are just thoughts and memories, they can reach any part of the universe, they may work together to create an independent universe. They can influence the past or travel to the future through dimensions, and they can also move a planet at will and place it in their preferred location, usually they don't always stay in one universe for a long time, because they are active in a range of trillions of universes, so it is difficult to meet them. Or the universe we live in is one of the things they created.

    Who knows what a 10-billion-year-old civilization will eventually become?

    It can be said that it is very powerful, and this invention is also very good. Arguably the most powerful top-level civilization. It is the most powerful in the universe.

    It's amazing. If the universe reaches the top civilization, it is very powerful, and it is several times more advanced than the current society.

    Alien civilizations definitely exist! Because the universe is so big, there are 200 billion suns in our galaxy alone! So full of possibilities for even the most demanding!

    And the conditions for life on Earth are not too harsh, nothing more than three:

    1. The distance between the earth and the sun is not close or far, resulting in the temperature on the earth just suitable for the existence of a large amount of liquid water.

    2. There is water on the earth.

    3. The earth has an atmosphere that can resist a large amount of cosmic radiation.

    If these three conditions are met at the same time, although there is no one in the solar system, but in our galaxy alone, I guess there are at least hundreds of thousands of blue earths like us full of advanced life.

    It's just that it's too far away to communicate.

    It is impossible to understand and describe without seeing it, and what is described is also based on human imagination, and human imagination is also based on what human beings know. What humans know is very limited, like a frog at the bottom of a well. The frog at the bottom of the well could not imagine what it would be like for the top civilization in the universe.

    We don't know what level of human civilization we have reached. How to judge the top civilizations? Perhaps we are now the most cutting-edge civilization.

    A higher level of civilization is that we overcome ourselves and keep artificial intelligence always within the control of human beings.

    Only by meeting this criterion can AI be self-aware. Otherwise, it is likely to be replaced or eliminated by artificial intelligence. Therefore, scientists have no viable solution, and robots must not have the ability to evolve themselves, nor should there be models.

    We can only do theoretical research on the computer. Because human survival must be cautious. 6G The New York Times will allow us to reach a higher level of civilization.

    In the era of the Internet of Everything, every Chinese does not need to work, and there are monthly living expenses paid by the state.

    All jobs are being replaced by AI robots. The main work of the people is social interaction, the study of the problems of population stability, the number of people who maintain the status of a great power, the training of the next generation of successors, and the transmission of smarter brains to various fields. Whether we are the most advanced civilization or not, we should seek more advanced science and technology.

    Constant progress can effectively control destiny. Wisdom is the infinite continuous development of our unknown territory, so that everything can be explained scientifically and reasonably.

    In the era of advanced science and technology, we will expand the field of humanity. Garrison the planets around the Earth to better defend the Earth. Unaffected by external factors, we are looking forward to this era and China's rapid development in the field of science and technology.

    Maybe everything we do today will affect the future. If you don't want to be eliminated, you only need to be rich and strong, study hard, and work hard. All the energy of the country will be devoted to the development of science and technology, the construction of a strong China, the beginning of the realization of a more advanced civilization.

    According to the relevant certifications, it is likely that extraterrestrial civilizations exist; It can use a series of top energy sources of black holes, and can take into account a series of energy sources of antimatter and use them in a controlled manner, and can effectively control the speed of the universe, which is greater than or equal to the speed of light.

    It is possible, it is simply unimaginable, that they may have mastered the mysteries of the universe, mastered the theoretical tools, more advanced than what people have now, and may have completed the speed of light.

    I think alien civilizations really exist; The top cosmic civilization should be able to achieve complete technology, very intelligent, and our entire life is controlled by machines.

    The current level of science has not yet been discovered, but we believe that it certainly exists, and with the development of science and technology, we will definitely be able to discover extraterrestrial civilizations in the near future.

    Currently, there are no extraterrestrial civilizations. Because the scientist sent an airwave out and received no response; And scientists used detection instruments, but they didn't detect it.

    There is no direct evidence for the existence of extraterrestrial civilizations, and as for the scientific basis, it is that Earth is in the space age. The alien civilization that has not appeared for many years has come into contact with the civilization of the earth.

    There are alien civilizations in the universe and space, why do you say that, because as long as there is everything with living things, even if it is similar to the existence of bacteria, life on a planet can evolve, just like the earth, although now relying on human technology there is no opportunity to explore, in countless galaxies, countless planets, as long as there are cells, there will be life, and there will be civilization.
