I. Six discussions of SEMI
SETI including 45-year-old search (SETI) 45-year-old search:
(1) Alien existence and
(2) We are You can communicate with them.
If you can do it, how does we come, how does we never get in an extreme skeleton?
This obvious puzzle has six basic explanations, which are not exclusively exclusive.
(1) is not present.
(2) The fact that we're advanced from us that we use our technologies from us, this is that we have not advanced enough technology to be recognized by them Repulsion of hypotheses.
(3) We are looking for aliens aliens.
(4) Ayrene is a life, we can not recognize or transmit them as felt.
(5) These aliens are attempting to communicate with us, but always fail due to various obstacles, structural, and certain situations.
(6) Our fraud (eg destruction of environmental destruction) or avoids for our characteristics (eg our congenital crawl) or ethical consideration.
Discussion # 1: Extraterrestrial Life Does Not Exist (Fermi's Principle)
The assumption that life only occurred on Earth is counterintuitive and unlikely. Rather, life is very likely to be a widespread parameter of the universe. In other words, it is as ubiquitous and ubiquitous as other generational phenomena such as star formation.
This does not necessarily mean that extraterrestrial life and life on earth are similar. Environmental determinism and Panspermia theory have not been proven. According to the Rare Earth hypothesis, there is no guarantee that we are not unique. However, it is likely that you will find life somehow elsewhere in the universe.
The widely accepted principle of mediocrity (Earth is a typical planet) and its embodiment, the controversial Drake (or Sagan) equation, usually predicts the existence of thousands of extraterrestrial civilizations. , Only a few of them may communicate with us.
But if that is true, to quote the Italian-American physicist Enrico Fermi, "Where are they?" Fermi hypothesized that a ubiquitous and technologically advanced civilization should be detectable, but it is not! (Fermi paradox).
This lack of observational evidence may be due to the fact that our galaxy is old. During the 10 billion years of its existence, most of the extraterrestrial races were probably simply dead or wiped out by various catastrophic events. Or perhaps older and perhaps wise races are not as enthusiastic about acquiring colonies as we are. Remote sensing may have replaced material exploration and physical visits to wild places such as the Earth. There are
aliens on our planet. The minds of newborns and animals are as inaccessible to us as the minds of small green men and antennal-wielding adductions. Moreover, as shown in the previous chapter, even adults with the same cultural background are strangers to each other. Language is an inadequate and dull tool when it comes to communicating our inner world.
Discussion 2: Their technology is too advanced If
aliens really want to communicate with us, why should they use technology that is incompatible with the level of progress in our technology? When we discover primitive tribes on Amazon, do we communicate with them via email or video conference? Or do you learn their language and how to communicate and try to emulate them to the fullest?
Of course, it is always possible that we are as far away from alien species as ants are. I try not to touch insects. If the gap between us and extraterrestrial life in the galaxy is too large, they probably don't want to communicate with us at all.
belief that life can exist in almost all situations and conditions, and that the range of planetary habitability is much wider than previously thought. I am.
However, regardless of their chemistry, most alien species are probably perceptual and intelligent. Intelligence is inevitably a great leveler and universal translator in our universe. It may not recognize certain extragalactic races as life forms, but it is unlikely to confuse their intelligence with naturally occurring phenomena. We can see other perceptual intellectual species, no matter how sophisticated and different, and they can recognize us that way.
Discussion No. 5: Unable to communicate with extraterrestrial lifeforms The hidden assumption underlying
CETI / METI (communication with ETI / messaging to ETI) is that extraterrestrial lifeforms such as humans tend to communicate. It means that there is. This may not be true. Interpersonal communication trends (not to mention interpersonal diversity) may not be universal. Also, aliens may not have the same sensory organs (eyes) as us and may not be familiar with our math and geometry. Reality can be well described and captured by alternative mathematical systems and geometry.
Also, complexity and order are often confused with artificial ones. Not all regular or constant or strong or complex signals are artificial, as the quasar example teaches us. Most heterogeneous linguists disagree with such monopoly, but even the use of language can be a unique human phenomenon.
Moreover, as Wittgenstein observed, language is essentially a private matter. If the lion spoke suddenly, we wouldn't have understood him. Modern verificationist and referenceist linguistic theories seek to separate the universality of languages in order to make all languages translatable-but they are still far from it. Clarke's Three Laws state that alien civilizations, far more advanced than humankind, can adopt research methods and, in principle, communicate in dialects that even humans cannot recognize.
Argument Number 6: They are avoiding us
Advanced alien civilizations may have found a way around the speed of light limit (for example, by using a wormhole). If they have and the UFO sightings are just hoaxes and hoaxes (as most scientists widely believe), we go back to Fermi's "Where are they?"
One viable solution is they're averting us due to our misconduct (example: the alleged destruction of the environment) or due to our traits (for instance, our innate belligerence). Or perhaps the Earth is a galactic flora and fauna reserve or a zoo or a laboratory (the Zoo hypothesis) and the Aliens do now no longer desire to infect us or subvert our herbal development. This falsely assumes that each one Alien civilizations function in unison and below a unmarried code (the Uniformity of Motive fallacy).
But how might they recognize to keep away from touch with us? How might they recognize of our misdeeds and horrific character?
Our earliest radio indicators have traversed no greater than one hundred thirty mild years omnidirectionally. Out tv emissions are even in the direction of home. What different supply of facts may want to Aliens have besides our very own self-incriminating transmissions? None. In different words, it's miles extraordinarily not likely that our recognition precedes us. Luckily for us, we're digital unknowns.
