What happened to all the aliens? Why haven’t we been contacted by another culture yet? A groundbreaking response comes from an astrophysicist: “Because the aliens are already here.”
In a new study, Zaza Osmanov of Georgia’s Free University of Tbilisi suggests that a species of alien people may be exploring our galaxy, including Earth, with “self-replicating probes.”
According to Osmanov, a civilization that has progressed to “Stage 2” on the Kardashev Scale, or one level above us, would be completely capable of manufacturing a fleet of “Von Neumann Probes.”
The Von Neumann probes would be “tiny self-replicating robots that would harvest materials from planets and asteroids in order to construct new copies of themselves,” according to the proposal.
“All of the data suggest that detecting a foreign object with extraordinarily high values of increased brightness may be a good hint to put the object on the candidate list for von Neumann alien probes,” the Russian astronomer wrote.
He went on to say, “We analyze the scenario in which type 2 civilization must” penetrate interstellar clouds by self-reproducing robots.” “And it has been demonstrated that this process will always result in observational consequences.”
However, when it comes to explaining why we haven’t seen this fleet of probes, Osmanov has a fresh idea that is completely plausible: “the probes are far smaller than the eye can see.”
“Or they’re outfitted with Stealth shields that are impenetrable to the naked eye, as well as a military radar.” It’s no accident that infrared cameras are the only way to capture UFOs in Russia and other regions of the world.
Nanotechnology, according to the scientist, is the natural choice for creating a probe that can move, construct swiftly, and adapt to a wide range of landing places.
“We compared the efficiency of Von-Neumann probes at the microscale to that of macro robots, and discovered that the former might [reproduce] more efficiently in interstellar media.”
“Large-scale automata can only replicate on rocky worlds, which necessitates greater maneuvering…
“Even if there were billions of these tiny devices penetrating the solar system, our existing technology would not be able to detect them.”
Each would be one billionth of a meter in size, or around one nanometer.
Despite the fact that the micro-machines are practically undetectable due to their small size, Osmanov believes there may be a way to detect them.
If these probes are fueled by light, they may produce modest amounts of light as they move through space, according to theory.
These streams of light would seem as comet “trails” if observed using infrared telescopes.
