Aliens may be a topic that never goes out of date, and people are always curious about it. Scientists have never given up on finding aliens for decades, but unfortunately, we have not found any valid evidence of the existence of aliens so far.
No one doubts the existence of aliens, but where are they? Why can't humans discover aliens?
In this regard, scientists analyzed that there may be several reasons
first of all, it is a factor in technology. To put it bluntly, there is a deviation in the direction of our search for aliens. For a long time, we can only rely on electromagnetic wave communication means to explore aliens and receive signals sent by possible aliens through various means.
The electromagnetic wave speed is indeed very fast, reaching the speed of light of 300,000 kilometers per second. But once it rises to the height of the universe, the speed of light will appear as slow as a snail. Even if aliens discover signals from humans, or we receive signals from aliens, we cannot communicate effectively at all because they are usually far apart.
There is also, although electromagnetic waves are the best way of communication for humans at present, who can be sure that aliens will also use the same way of communication? For a highly developed alien civilization, electromagnetic waves seem too backward, and perhaps they have discovered more advanced and more effective communication methods long ago.
In this way, just like humans trying to communicate with ant with electromagnetic waves, ants will definitely not be able to discover the existence of humans.
The second, perhaps the most fundamental factor, that is wisdom. Humans consider themselves the wisest life on earth, but in fact it is likely that this is indeed true. But even so, human wisdom may be instantly ruined in the face of more advanced alien civilization wisdom.
There are too many low-level animals in our eyes on the earth, but can people communicate effectively with those animals? It's hard, we don't explain geometric mathematics or even calculus like animals, because we know that it's purely playing the piano for cows.
Similarly, in the eyes of advanced alien civilizations, they may have long discovered high-tech such as anti-gravity that is beyond our imagination. In our eyes, humans are "monkeys". Think about it, would you establish some kind of effective communication with a monkey?
The last factor is the uncontrollable factor, the destruction of civilization. From the current development process of human civilization, we can see that more than 200 countries on the earth have as many as tens of thousands of nuclear warheads, and these nuclear power is enough to destroy humanity. Don’t forget that modern human civilization only has a history of hundreds of years. It is impossible to imagine how terrifying super weapon an alien civilization that has developed for tens of thousands of years or even longer will have!
The vast universe, there are too many things that we unexpectedly exist, and our curiosity is driving the continuous development of human civilization!
