As early as 1950, Enrico Fermi presented what is now called Fermi Paradox: Given that there are countless galaxies, stars, and planets, life is likely to exist elsewhere-so why haven’t we discovered it yet? The size of the universe is only one possible answer. Maybe humans have already encountered extraterrestrial (ET) life, but didn’t realize it.Maybe it Don’t want to be discovered. Maybe it is monitoring the earth without our knowledge. Maybe it won’t make us feel interesting.
There is another reason: the search for advanced aliens is limited by human assumptions, including the idea that advanced ET will be “alive.”
Scientists engaged in the search for extraterrestrial life need what it takes to find life on Earth — carbon and water — and Biosignature: Gases and organic substances exhaled, excreted or secreted by organisms, such as methane.It is difficult to find biosignatures for many reasons, and biosignatures do not necessarily indicate the existence of life, because they may come from geology or other natural forces (for example, a Methane detected on Mars It has been attracting scientists for many years, but they have not yet reached a consensus).
The assumption that biological life on other planets looks or functions similarly to biological life on Earth is flawed and limited by anthropocentrism. Assume that advanced intelligent life on other planets is biological, just because humans are biological. Maybe we have not found aliens, because advanced alien space has completely surpassed biology.
In Shanda plan, The earth is a relatively young planet. If we assume that certain biological life appears on other planets, then we can also make some educated assumptions about how this life evolved-that is, other species have also invented technologies, such as tools, vehicles, Factory and computer. Perhaps these species invented artificial intelligence (AI) or virtual worlds. Advanced ET may have reached “Technological singularity“The point where artificial intelligence surpasses human or biological intelligence. Maybe they have experienced what many scientists think are prepared for Homo sapiens—— The fusion of biology and machine. Maybe they have become Nanosatellite. maybe They are data Or part of a digital network that operates like a collective consciousness.In fact, the last variable Drake equation-A framework for estimating the possibility of advanced intelligent species in the universe-Assuming that technologically advanced civilizations broadcast detectable signals within a limited time, this indicates that they will eventually become extinct or become post-living creatures.
This idea ET intelligence may exist in the form of “super” artificial intelligence Has been proposed by scientists, such as Susan Schneider, Founding Director Future Thinking Center; SETI Senior Astronomer Seth Shostak; And others.in a Designed for protectorShostak assumed that the aliens were smart enough to find the Earth “may have surpassed biological intelligence, in fact, surpassed the biological itself.” Caleb Sharp, Director Colombian Astrobiology Program, think “Just as people living on the Mongolian grasslands in the 12th century found self-driving cars to be magical and meaningless, we may not be able to record or explain the existence of machine experts billions of years ago.”
The potential of AI excellent Artificial intelligence has greatly exceeded the limits of human intelligence for a long time Concerned scientists like Nick Bostrom And entrepreneurs like Elon Musk, So the possible existence of super AI aliens raises important considerations about the risk of searching for and finding them. It also raises questions about the potential danger for them to find us. Dark forest theory Sorting out these threats shows that the universe is similar to a dark forest full of predators and prey. Stealth is the best and perhaps the only survival strategy.
