There are scientists who say not to deny the possibility that extraterrestrial probes are exploring the Universe. There is a possibility that we will find some of them very close to 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 to reach star systems on its own. The alien probe can even determine the intelligence level of the species it comes into contact with before it can communicate with the device.
A fleet of alien probes can track our galaxy on a regular basis, scientists say. But if this was real, why haven’t they been able to find out until now. Extraterrestrial probes may be so small that they cannot be discovered, said astrophysicist Zaza Osmanov.
He also explains that these civilizations could make self-replicating spacecraft for exploration in a risk-free manner. The probes can float using hydrogen atoms in interstellar dust and can still look for evidence that extraterrestrial life exists.
When looking for signs that extraterrestrial life exists, we also assume the search for artificial radio signals. They could easily self-replicate into a swarm of trillions of billions. The universe could also be full of swarms of small probes.
Osmanov says these swarms should generate some light. And these traces can be interpreted as other traces of a distant comet. It was considered a scenario in which a Type 2 civilization, with the help of self-produced robots, could scatter interstellar clouds filled with nano-probes. If they remain as swarms, they will likely be visible.
Physicist Paul Davies says there is a possibility that a Von Neumann probe could have landed 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 spacecraft’s behavior: using standard powered flight, using gravitational slingshot techniques around stars, and star-to-star hopscotch to get the maximum speed increase in slingshot trajectories. A Voyager-like probe that explored the galaxy could do so 100 times faster by pulling out these slingshots.
