The expert NASA Silvano P. Colombano said that extraterrestrial beings may have visited Earth and probably far beyond human technology that we are simply unable to detect them due to the lack of knowledge.
This writes the lifter with a link to the Daily Mail.
Silvano P. Colombano from the Department of intelligent systems at NASA, believes that extraterrestrial life may be very different from human life, which is based on carbon, and our current thinking about extraterrestrial life too narrow.
“I just want to point out that the intelligence that we could find, and who could find us (if not found), can be constructed not of carbon organisms, such as we are,” said Colombano at the workshop “Deciphering foreign intelligence.”
He believes that alien life may have gone far beyond human technology, and perhaps have mastered interstellar travel. Besides, aliens can be extremely tiny super-intelligent entities.
“The technological development of our civilization began around 10 thousand years ago, and the growth of scientific methodologies only in the past 500 years. Therefore, we can assume that we may have a real problem in forecasting the evolution of technology even in the next thousand years, not to mention millions of years”, – said the scientist.
Colombano encouraged physicists to take part in the “speculative physics” based on the evidence-based theories, but “with some willingness to expand the possibilities about the nature of space-time and energy” and “to consider the UFO phenomenon as worthy of study”. He also warned that radio waves can be outdated.
