There are scientists who say not to deny the possibility that ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ probes are exploring the Universe. There is a possibility that we can find some of them right in the vicinity of the Earth and explore our planet. Using Von Neumann probes, we have many advantages when exploring the Universe.
This Von Neumann spacecraft is actually a spacecraft capable of replicating itself in order to reach star systems on its own. The a̳l̳i̳e̳n̳ probe can even determine the level of intelligence of the species it comes in contact with before it can communicate with the device.
A fleet of a̳l̳i̳e̳n̳ probes can track our galaxy on a regular basis, scientists say. But if this were real, why couldn’t they find out so far. E̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ probes can be so small that they cannot be discovered, said astrophysicist Zaza Osmanov.
He also explains that these c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s could make self-replicated spaceships for exploration in riskfree ways. The probes could float using hydrogen atoms in interstellar dust, and they could still look for evidence that ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ life exists.
By looking for signs that ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ life exists, we also assume the search for artificial radio signals. They could easily self-replicate into a swarm numbering trillions of billions. The universe could also be full of swarms of small probes
Osmanov says that these swarms should generate some light. And these traces could be interpreted as other traces of a distant comet. A scenario was considered in which a type 2 c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳, with the help of self-produced robots, could spread interstellar clouds full of nano-probes. If they remain as swarms, then they will probably be visible.
Physicist Paul Davies says there is a possibility that a Von Neumann probe may have crashed right on our moon, following a previous visit in the distant past.
Scientists Arwen Nicholson and Duncan Forgan say there are three scenarios in the probe’s behavior: using standard powered flight, using gravitational slingshot techniques around stars, and hopscotching star-by-star to get the maximum speed boost under slingshot trajectories. A Voyager-like probe that explored the galaxy can do it 100 times faster when taking these slingshots.
