Scientist: Humans' Chances of Encountering Alien Civilizations Too Low, Concerns That Damage Our Cognition - New Era

When we look at the stars, we always wonder: Are humans alone in the universe? This kind of thinking has always been in the heart of man ever since man was born in the world and again started understanding the universe.

Some friends would think that for more than half a century man has not found any trace of an alien civilization, making man the only intelligent civilization in the universe. However, most people are still reluctant to accept such cognition. In the eyes of many, the universe is vast and mysterious, too big for us to imagine. There are galaxies and planets that are difficult to count. There must be a very intelligent life out there.

Maybe as long as friends with definite knowledge of the universe will believe that alien civilizations exist based on current human understanding of the universe, the observable distance is 93 billion light years, and within this range, the “galaxy” There are trillions. , “Each ‘galaxy’ contains hundreds of billions of star systems, and each star system will have a different number of planets, including the terrestrial planets.

Every star system has a habitable zone, and there will be at least one terrestrial planet orbiting around it. In this way the number of habitable planets in a galaxy can reach millions. A vast order of magnitude, a planet containing life, knowledge of civilization is also common.

Earth is very small in terms of the universe, and it is also a planet of normal life. Nothing Important. Since Earth can give rise to intelligent life and civilization, other habitable planets can too.

Life is not a strange thing in the universe, and it may still exist universally. In that case, why haven’t humans discovered intelligent alien life in the universe, or even traces left by ordinary alien life?

Such an outcome seems so impossible, what happened? Several scientists have published a paper showing that the chances of humans encountering alien civilizations are very low, and the difficulties are far greater than we imagined.

It makes no sense for scientists to propose such an approach. He offers many proofs. One of the important points is that it is absolutely impossible to comprehend the scientific and technological power of an alien civilization with the current scientific and technological power of mankind.

For more than half a century, humans have searched for alien civilizations primarily by listening to the starry sky through radio telescopes to detect signs of possible alien civilizations. Scientists have sent information about humans and Earth to the depths of the universe, hoping to reach an extraterrestrial civilization. Star Civilization Reaction.

So is listening to cosmic cues paying off as expected? The answer is no. For more than half a century, telescopes have discovered a large number of cosmic signals, but these signals are essentially from celestial objects or cosmic phenomena. Even though there are some mysterious and regular signs, we do not have the capacity to understand them. Naturally, they did not know its origin.

Some scientists believe that the radio signals currently used by humans are very primitive and backward mode. Its propagation speed is only the speed of light. After reaching the universe, as the distance increases, it will keep on decreasing.

The distance to the universe is measured in light years, and galaxies are far away, so even if signals sent by humans could reach the target galaxy, they would be swept away beyond recognition, and mixed with the background noise of the universe.

Could alien civilizations use this old method of signal propagation? If a civilization progresses to the interstellar phase, the wireless signal modes currently used by humans are too backward to be compatible with interstellar travel connections. Therefore, the wireless communication used by interstellar civilization must be more advanced, the transmission speed is higher than the speed of light, and the distance is far, and the signal failure situation will not be easy.

Our current telescopes may not be able to receive signals that are completely different from human signals. Even if we accepted it, we still wouldn’t understand it, and certainly we wouldn’t be able to contact alien civilizations.

In addition to the various signal patterns that break the connection between human and alien civilizations, there is another situation we must consider, namely that there can only be human civilizations in the galaxy. From the point of view of the Solar System, the Milky Way is huge, but from the point of view of the Universe, the Milky Way is very small, and there is only one civilization in a tiny speck of dust, which seems reasonable.

If there is only one intelligent civilization in the galaxy, humans, then if we want to come into contact with alien civilizations, perhaps only when human technology advances into the interstellar phase and has the ability to leave the galaxy, can we hope.

If there are many high-level civilizations and civilizations in the galaxy, but humans have not found them yet, then there is a possibility that a region of the universe where Earth is located is blocked by alien civilizations, and the growth and development of low-level civilizations. The study is done in the same way that we study mice in the laboratory for their growth and development.

Whatever the situation above, it is not too bad for humans. At least we still have hope that our day will come into contact with alien civilizations, but in recent years, several scientists have proposed a more terrifying, subversive cognitive approach: the universe in which humans live may be virtual. .

Some scientists have put forward the idea that humans might be in cyberspace today, that our world is a virtual program, and humans are a kind of code of knowledge. Other than that, there is no other kind of knowledge code. If so, it would be impossible for humans to find other intelligent life, and even the fate of humanity concerns us.
