I couldn't help asking: "It turns out that you are the legendary famous Shennongjia savages, we finally saw your true face of Lushan today, it is really a blessing for three lives, and I am very fortunate to be able to know you who are known to all women and children, and you are famous far and wide." ”

A slightly taller savage in front of him was busy in the standard Da Song dialect: " We are also very happy to meet you, and we are destined to meet in the past, but in fact, your statement is not accurate enough, although other people call us savages, but in fact we are not savages, but this is to open the conversation box, it is a long story, it is estimated that in detail, I am afraid that I will not be able to finish it for three days and three nights, but I am afraid that those masked people who will not go away will chase after me, so I will not talk to you more now, and when we get to a safe place, we will make it clear to you again, now is not the time. “

Xiao Fei said curiously to the wild man in front of him: "Since you said that you are not a wild man, looking at your height and so on, you don't look like us, could it be that you are aliens?"

I couldn't help but laugh in my heart Xiaofei was whimsical, how could it be, it was completely unbelievable. Modern society has not confirmed whether there are aliens, how can there be wild people in the distant Great Song Dynasty, I didn't expect it, what I didn't expect was that the wild man in front of me actually smiled and said: "Yes, you're right, we are real aliens, but now I don't have time to explain too much to you, when you get to the destination, you will naturally know." ”

Xiao Fei and I looked at each other dumbfounded, it turns out that there are really aliens in the world, and now, in the Great Song Dynasty of our country, there are aliens, they are not the wild people of the Shenlong frame, but the aliens of the Shenlong frame, it is really unexpected, eye-opening, we looked at the so-called wild people in front of us in amazement, how can we not connect with the image of aliens created in TV and movies, completely different, and countless questions are surging in my mind, such as why do they speak Chinese, and they speak so fluently and so well, how do they know Mr. Wang DalongBut what do they eat and drink? Will they be bad for us? But what do we want in their hands, whether it's the Longtan Tiger's Den, we have to go in to find out, and what planet they come from? Why don't they go back? Why don't they go back? Do they stay on our earth for a hundred years, day after day, year after year? Do those ancient buildings such as the pyramids of Egypt have anything to do with them? Is the albinism phenomenon in Shennongjia also related to them?, and so on, and I can't help but think of the introduction of aliens in Baidu in modern society, and I feel that their existence may be scientifically justified.

I said to Xiao Fei in disbelief: "I didn't expect them to be aliens, I didn't expect aliens to really exist." ”

Xiao Fei also said freely: "I am a lover of the cosmic starry sky, I often look up at the starry sky when I have nothing to do, I feel very interesting, and I also have a lot of research on aliens, in fact, aliens are the general name of human beings for the life outside the earth in the illusion." There have always been reveries about aliens at home and abroad, but human beings in modern society have not been able to actually detect the existence of aliens, although for a long time, many people claim to have witnessed aliens visiting the earth, and even having contact with themselves, but most scholars and experts believe that the so-called different degrees of contact between humans and aliens are actually psychological effects, and the chances of human beings discovering aliens are very small, even if they find the existence of aliens, it is almost difficult to have any contact with them. I didn't expect them to say that they were aliens, which was really eye-opening, and in the past search, astronomers did not find any conclusive clues about aliens. As of 2015, the scientific community generally believes that life only occurs on planets around stars that emit light and heat, but not all stars necessarily have planets. Nebula theory holds that stars were formed from the contraction of a rotating primordial nebula. During contraction, the rotation is accelerated due to the conservation of angular momentum, and the nebula gradually becomes flattened due to the action of centrifugal force. Stars are born when the core temperature reaches 7 million degrees Celsius, and a thermonuclear reaction from hydrogen to helium occurs. In the process, the outer part of the disk condenses into several small celestial bodies - planets. The evolution of living things is an extremely slow process, and the time it takes is comparable to that of the sun. Fossil studies have found that as early as 3.5 billion years ago, there was a relatively advanced single-celled organism on Earth, called blue-green algae. According to the theory of stellar evolution and the analysis of ancient rocks and meteorite materials on the earth, it is known that the formation of the sun and the earth is 10~1.5 billion years earlier than the appearance of this creature. It took about 5 billion years after the formation of the solar system to have humans on Earth. It is envisaged that every 5 billion years will be compressed into a simple scale of one year. On such a scale, one week is equivalent to 100 million years of real life, and one second is equivalent to 160 years. About two years have passed since the Big Bang and the birth of the solar system. The Earth was formed in January of the 3rd year. In March and April, the ancient single-celled organism of blue-green algae appeared. Since then, life has evolved slowly and without stopping. The first large cells with nuclei appeared on Earth in September, and multicellular organisms may have been present in late October. By the end of November, plants and animals had taken over most of the landmass, and the earth had become active. On December 18th, the dinosaurs appeared, and these incredible behemoths dominated the earth for only a week. At 11 p.m. on Chinese New Year's Eve, the Pekingese came out, and 10 minutes before midnight, the Neanttes appeared at the Chinese New Year's Eve party. Modern humans are only able to show up 5 minutes before the arrival of the new year, while the written history of mankind begins 30 seconds before midnight. The major events of modern life sped up one after the other in the last seconds of the old year, and the population of the earth tripled in the last second before midnight.

It can be seen that the earth has been nurturing life for most of the time since its birth, but only for a short time life has taken the form of advanced organisms. As we have seen, the birth of intelligent life requires that stars must be able to emit light and heat stably for at least about 5 billion years. The lifetime of a star is closely related to the size of its mass. The thermonuclear reaction of massive stars can only last for a few million years, which is far from enough for the evolution of life. Only stars of similar solar mass are suitable candidates, and there are about 100 billion such stars in the Milky Way, and about 40 billion for a single star except for binary stars. Unfortunately, we don't know much about other planetary systems, but observations have gradually led to the presence of planets around some stars. Considering the objective existence of the solar system, even large planets have their own satellite systems, such as Jupiter in the solar system. It is possible to optimistically assume that all single stars have planets. The existence of planets does not mean that there is life, let alone the existence of higher beings. The key is that the distance from the planet to the parent star must be just right, not far or near. Due to the limited level of understanding, we can only discuss life forms with conditions similar to those of the Earth, and in particular assume that liquid water must exist. There are eight planets in the solar system, but only the Earth is clearly in the so-called ecosphere that can form living things. Venus and Mars are located on the edge of the biosphere, and no life has been shown on their surface. It is very rare for a planet to have all the conditions necessary for life to exist. In the solar system, the Earth is unique and lucky. Detailed calculations show that of the 40 billion individual stars mentioned above, only 1 million are surrounded by planets that can allow life to evolve to an advanced stage. Another constraint is that extraterrestrial life should have a similar chemical composition to life on Earth. Astronomical observations show that, with a few exceptions, the distribution of chemical elements throughout the universe is fairly uniform, and there is every reason to believe that the materials needed to make up all the organic molecules can be found on distant planets. In fact, many of the more complex organic molecules have been found in many places. Thus it can be assumed that life somewhere, as long as it is theoretically possible, will actually be formed. There will be a million planets in the galaxy that could have life, but life on each planet should be at a different stage of evolution. Reports of aliens are often reported in the newspapers, and many people claim to have seen flying saucers, and even seen aliens, and they have also taken all kinds of photos about flying saucers. This is true in modern society, everyone has aliens, and everyone has expressed their opinions and talked about it. According to people who claim to have seen aliens, most of the aliens they see are short, round-headed, narrow, crack-like mouths, and humanoids in tights. Others are keen to look for traces left by aliens in ancient times. They believe that the round masks of the figures depicted in the murals of the Sahara Desert, the megalithic buildings of Easter Island and South America, and the pyramids, among other unexplained prehistoric wonders, are related to aliens. Other scholars have put forward various ideas such as that humans are descendants of aliens, or that some peoples of mankind (such as the Maya) are descendants of aliens mating with earthlings. But these can only be used as speculations and hypotheses, most of which still lack sufficient evidence. Scientists have come up with all sorts of possible scenarios for the existence of aliens, which are bold and bizarre, but who can blame the human imagination, and perhaps these fantasies will one day become appreciable. If we rejoice in the large number of 1 million and think that finding aliens is not a problem, it will be too early to rejoice. For extraterrestrial beings, it only makes sense if you can connect with them. As far as human understanding is concerned, radio signals are the only viable way to establish such a link, and it is therefore necessary to further explore the number of planets inhabited by civilized beings capable of sending such signals. If they've been sending this kind of signal since their existence, there should be a million planets that are being radioed. But in fact, not to mention algae, even humans did not have this ability more than 100 years ago. On the other hand, neither will life forms that have been destroyed by technology, and that have themselves been destroyed. At about the same time that they were able to emit radio signals, humanity also developed massive nuclear weapons that could wipe out all living things on Earth. Will aliens destroy themselves at the mercy of a war maniac who has lost their minds?

Let us be optimistic once again that aliens are capable and rational to solve those problems we fear, and assume that they have lived in peace and prosperity for 1 million years. Because of the great development of science and technology and the abundance of life, they will inevitably think of, and fully afford, to spend huge sums of money on groundbreaking research of great significance, including attempts to establish contacts with their counterparts in the outside world. They sent powerful radio signals to the outside world without stopping for 1 million years. As a result, a small fraction of the 1 million planets are broadcasting this signal, which is 1 million years divided by 4 billion years, or 0.025%. This means that only 250 are sending signals. If they are evenly distributed in the Milky Way, the distance between the two adjacent ones is about 4600 light-years. It would take 4,600 years for human signals to reach our nearest aliens. If they receive an answer and send an answer right away, we'll have to wait patiently for 9200 years to hear back from them! The contact person of the Ozma Project is only a dozen light-years away from us, and it really doesn't make much sense to do so. For the project to be meaningful, it is necessary to listen to each single sun-like star within 4,600 light-years to see if it is emitting meaningful signals. To be more realistic, consider that there are only 4,000 years of recorded human history. If aliens were only capable of broadcasting on the radio for a period of 4,000 years, then today there is only one planet broadcasting signals to the outside world! Therefore, there is at best one more civilized creature in the entire galaxy besides the earth sending signals, and all our efforts to listen attentively to such signals in the galaxy with radio telescopes will be completely futile! Is there a planet around every single star? Can life only be born in an environment like the earth? Also, we don't actually know how long an intelligent creature can survive, and whether they can survive forever? These questions may not be answered definitively for a long time. However, how could primitive man have imagined today's large airliners, color televisions, fast electronic computers, and lunar landings? As long as mankind can continue to live in a peaceful and prosperous environment, the development of science will gradually answer these questions. However, even if aliens exist, we will not be able to make effective contact with them for the time being. Therefore, it is probably not credible to associate UFOs with spacecraft from outside the sky. Therefore, extraterrestrial research is no longer science fiction, but an interdisciplinary ——— an important topic of astrobiology with attractive prospects. According to scientists, there are about 100,000,000,000 stars in the entire galaxy, and about 100,000,000,000 galaxies in the entire universe. If we assume that the probability of life is 1 in 1,000,000,000,000, then there will still be 100,000,000 planets with life.

Many people believe that time travel is impossible to achieve, after all, the distance between stars is measured in light years. However, they ignore the fact that in the mid-19th century, scientists thought that 55 km/h was the maximum speed that humans could achieve, but in this day and age, we have left the speed of sound far behind, and it took less than 200 years. So why can't there be a race on these 100,000,000 planets where life could possibly have invented and mastered the method of interstellar travel beyond human intelligence? Although scientists have been debating the existence of black holes, after all, from an astronomical point of view, black holes cannot be observed by conventional telescopes, but the vast majority of astronomers still believe in the results of radio telescope observations, believing that there is indeed such a celestial body that can absorb light. So through the analysis, it can be seen that aliens may really exist, maybe they are not fake aliens, maybe they are real aliens, and when we get to the destination later, we will ask them clearly, understand. ”

I secretly sighed in my heart that Xiao Fei is indeed a senior astronomy enthusiast, and he is right-founded, and he quickly said that it is true, and I also saw the main theories and hypotheses about aliens on the Internet when I was in modern society, which is particularly interesting, such as the theory of underground civilization - it is reported that after the American artificial satellite "Charlie 7" went to the Arctic Circle to shoot, it was found that a hole in the Arctic zone was found in the negative. In addition, geophysicists generally believe that the earth weighs millions of times more than 6 trillion tons, and if the earth's interior were a entity, the weight would be more than that, thus giving rise to the "earth hole theory". Some of the oil exploration team members have found large tunnels and huge underground people underground. We can imagine that the earthlings are divided into surface and insider, and that the underground people of the underground kingdom must have mastered science and technology higher than that of the surface people, so that it becomes logical for them, the same star of the earthlings, to travel through space in flying saucers that the earthlings cannot yet make. There's also the mixed dwelling theory, which holds that aliens live and work among us. In some of the photographs taken by the researchers with a surprising new radiation camera, some people were surrounded by a pale green halo around their heads, possibly caused by rays emitted by their brains. However, when trying to query the people with halos, it was found that the people had disappeared completely, and there was not even any sign of their former existence. Aliens are hiding among us and we don't know what they're going to do, but there's no evidence that aliens can harm us. There are also human ancestors who say that the ancestors of human beings are aliens. About tens of thousands of years ago, a group of aliens with a high degree of intelligence and scientific and technological knowledge came to the earth, and they found that the environment of the earth was very suitable for their habitation, but because they did not bring sufficient facilities to cope with the geocentric attraction of the earth, they changed their original intention and decided to create a new human race - the combination of aliens and earth ape-man. They targeted female apes and tried to impregnate them, resulting in today's humans. The most widely circulated parallel world, the universe we see (i.e., total galaxies), could not have formed within the four-dimensional universe, that is, the world around us was not formed only in the dimensions of length, width, height, and time. The universe may be made up of two worlds adjacent to each other, and although they are connected to each other, they are almost transparent to each other, and the two material worlds are usually "shadow" worlds that have little interaction with each other. When these two stacked worlds are formed, they are "composite" into one with great interaction force, and various substances are highly mixed together to form a unified world. Later, the universe expanded, and at this time, the density of matter decreased, and the gravitational force decayed, resulting in two worlds that were actually separate from each other. In other words, it is entirely possible to exist in the same time and space in an invisible parallel world adjacent to us, which may or may not be very similar to ours, or it may be completely different from ours. The laws of physics and chemistry may be the same, but the actual conditions are different. These two worlds dominated each other 200-15 billion years ago. Therefore, it is possible that the UFO came from that other world. It may have been accidentally intruded under some special conditions, or it is more likely that they have already mastered the knowledge of traveling between the two worlds, and often travel between the two worlds, and their technological level is far beyond that of us humans. There is also the four-dimensional space theory - some people believe that UFOs come from the fourth dimension. The ghost-like aircraft disappears in an instant, and the network of artificial satellite electronic tracking systems cannot be watched at all when it is turned on, so it can be assumed that the crew of the UFO is playing with time and space. A technical means can form some local spatial curvature, and this local curved space can then expand in the space in contact with it, and after this step is completed, people from another space can come to our space. As various sightings have reported, concrete and tangible creatures suddenly emerge from the ground near a UFO, rather than apparently running out of a door.

However, their doctrines, found that we have not seen the real aliens to be real and sensational, compared to theirs are hypotheses, generalizations, we are real evidence, and maybe we can bring an alien back to the modern society, we will become the most well-known people in the world, but unfortunately the current situation is that we can't go back, not to mention to bring a more than 2 meters tall alien home, it's just a fool's dream, but we can take more photos after we get their consent later, maybe in the future there is a chance to return to the modern society can come in handy。 “

Xiao Fei and I followed closely behind the wild men and aliens, talking, eyebrows fluttering, unconsciously a huge cave appeared in front of our eyes, it seems that this is the alien base, we can't wait to follow them into the huge and deep cave that can not be seen.
