Find a Question:
Is it too primitive our technology to find aliens?
Several leading astronomers from around the world, including British Astronomer Royal Sir Martin Rees, it is believed that the aliens do not use a variety of visible light or radio waves for communication (they can not even see it ), and a completely different type of data transfer. Ghostly neutrinos or gravitational waves (ripples in the fabric of space-time) or no communication mechanisms that we are unable to understand.
“The fact that we have not yet found the slightest evidence of life – much less reasonable – beyond Earth,” – said Arthur C. Clarke – “not surprised and did not disappoint me in any degree. Our technology should be laughably primitive. Perhaps we are like savages of the jungle listen to there-Tamam, while the ether around them carries more words per second than they could utter a life. ”
Lord Rees, a leading cosmologist and astrophysicist, and the president of the Royal Society of British astronomers, believes that the existence of extraterrestrial life may be beyond human understanding available.
“Perhaps they look us in the eye, and we just do not see them. The problem is that we are looking for something very much like us, assuming that they have our counterparts in mathematics and our technologies. I suspect that the mind and life may exist in forms that we can not imagine. Just as a chimpanzee can not understand quantum theory, there are aspects of reality that are beyond the capacity of our brains. ”
Frank Drake, the founder of SETI and the creator of the Drake Equation, believes that satellite TV and the “digital revolution” have made humanity invisible to aliens by cutting the transmission of TV and radio signals into space. Earth is now surrounded by a “shell” of radiation, which extends for about 50 light-years from analogue television and radio and radar transmissions. According to Drake, digital TV signals would look like white noise for the curious aliens.
Although the signals have spread far enough to reach many nearby star systems, they are quickly dissolved in digital technologies. In the 60’s led the transformation of Drake Observatory in Arecibo radio astronomy facility. As a scientist, Drake was involved in the early work with pulsars. Drake has also developed a “pioneering the board” with Carl Sagan in 1972, the first physical message in the space. The board was designed to be understandable to aliens if they run with it.
Milan Cirkovic of the Astronomical Observatory in Belgrade, points out that the average age of the terrestrial planets in the Milky Way about 1.8 Gyr (1 billion years) is older than the age of the Earth and the solar system, which means that the average age of technological civilizations should be older than the human for the same period. The magnitude of this term means that one or more processes must suppress observability of extraterrestrial societies.
Since currently there is no direct or obvious evidence that extraterrestrial life exists, likely several consequences:
We (A) the first intelligent beings capable of making our presence known and leave the planet. At the moment there is no other life that has developed to the same level as us. Or perhaps extraterrestrial life exists, but for some reason is very rare and is so far away that we will never be able to enter into contact with it. So, extraterrestrial life is almost non-existent.
Or (B) many advanced civilizations have existed before us, but for some reason have become extinct or evolved to such an extent that they became completely undetectable to our toolbox.
Or (c) there are other civilizations, but they are faced with a sort of “cosmic roadblock” that destroys them, or at least prevents their expansion beyond a small area.
Since the placement of the Earth in space and time does not seem coincidental, option “A” looks very unlikely. Assuming that humans evolved like other forms of life in the present state, there is nothing strange, surprising or remarkable in the fact that they can develop other types that support life on other planets. If so, then the chance that humans are the first species that may leave a significant mark in the history of the universe from the point of view of statistics is incredibly small.
To option «B» load have to ignore all logic. If potentially thousands, or even millions exist in the known universe, why they decided to move there, or so that they can not be detected? Some would definitely go that route, but that all – is unlikely.
Option «C», in some ways, it seems more likely than the «A» and «B». If the principle of “survival of the fittest” and is working on other worlds, our own “civilized” nature may be typical for extraterrestrial civilizations.
