The recent discovery of a planetary system thought to be more than twice as old as our own should let us scan whether an alien race advanced beyond our comprehension has been visited by earth – or maybe even remains here now, undetected.
That's the grade NASA scientist Silvano P. Colombano recently made in a research paper that recommends "a new, more aggressive approach" to the US. It. Location agency & # 39; Search for extra-terrestrial life.
"Consider … Because technological development in our civilization has begun just about 10 years ago and has seen the rise of scientific methods only in the past 500 years, we can reflect that we may have a real problem in predicting technological evolution even for those Next thousand years, let only 6 million times that amount! "Wrote Mr Colombano, who works at the NASA Ames Research Center in California.
"In light of the numbers, I think we need to re-visit even our most cherished assumptions (that) interstellar travel is impossible or highly unlikely."
While the distance and energy, and our own understanding of physics, makes such travel impossible for us, there is still a lot of space for "control of energy-energy and space-time" to have evolved into older societies, he poses.
Other simultiations that you need to ask are intelligent civilizations that will be based on carbon life like us and that we will be able to detect them by our current method of scanning the cosmos for radio waves.
While it is possible that a more advanced foreign civilization will continue to use radio waves to communicate, their radio waves can be packed with so much information scientists can get them now and would not be able to distinguish it from "noise", he is theorized.
And a quick look at the past 50 years of computer evolution on earth shows that "our form of life and intelligence can only be a tiny first step in a continuous evolution," Mr Columbiano wrote, suggesting that other civilizations may have shed the "carbon Machinery "humans rely on physical.
He also suggested that NASA does not put all of its energy into the so-called gallidlocks planets – those considered most similar to Earth – discovered in recent years.
"While it is still reasonable and conservative to consider that life is most likely to be brought into conditions similar to our, the vast time differences in potential evolutions render the likelihood of 'matching technologists very clarified,' he Said.
The paper encourages NASA to have more of an open mind to "speculative physics … with some wildness to stretch possibilities as to the nature of space and energy"; To show technologists to look at "how technology can evolve … and symbiosis of biology with machines"; To have sociologists prepare us for what to expect from more advanced society; And to get UFO reports more seriously.
"It seems to me that SETI has ignored the potential relationship of UFO phenomena (at least officially)," he wrote, referring to the acronym for the "search for extraterrestrial intelligence."
One of the reasons, he noted, is "the very high likelihood of hoax, error perceptions or even psychotic events." However, if scientists brand all "noise" with an eye for the "phenomena that can not be explained or denied … we could start some serious inquiry".
