Computer simulation conducted by a duet of researchers from the University of Edinburgh (UK) showed that a flotilla of interstellar probes of aliens would have time to study our entire The whole galaxy in a fairly short time. Our Voyager 1 in 36 years he was able to retreat from the earth in less than one daylight. However, the simulation suggests that the alien ship enough to develop only 10% of the speed of light to consider the whole The Milky Way for some 10 million years. In doing so, he could accelerate (and thereby save fuel) due to the gravitational field of stars. The thought of probes that are self-aware and capable of self-reproduction, appeared in the 1960s. American astronomer Ronald Bracewell suggested searching for them, not radio signals of artificial origin relied on by the Institute SETI. A mathematical model of a machine that clones itself, John von Neumann developed even earlier – in 1949, and talk about such devices and a hundred years. In the new work Arwen Nicholson and Duncan Forgan goes even further by offering three scenarios of behavior probe: flight with engines on, use gravitational acceleration and jumping from star to star. For instance, Voyagers fly like pinballs – bouncing off gravitational fields of the massive outer planets of the solar system. By comparing the speed of the probes with the number of stars in the galaxy, the researchers concluded that they would have time to explore the Milky Way for a very a short period in the life of the Earth and thereby justify the known Fermi paradox solution. Lovers gossip about UFOs long ago on him answered: do not look among us, here and now, witty greenish little men. If someone flew in, it was more likely total rare visits of robotic and almost immortal apparatuses. Moreover, they may have had reasons carefully cover your tracks as soon as the exploration of the solar system (then more likely, deprived of intelligent life or even life in general) has been completed. One of the most impressive descriptions of such the robot was given in 1972 by the great Arthur Clark in the novel “Date with Frame “. A giant” ark “of cylindrical shape enters the Solar the system. A group of astronauts penetrates and becomes witnessing how the automatic mini-world is gradually Awakens from interstellar hibernation, approaching the Sun. In the end Finally, people understand that the ship is not going to stop: our star will give him the desired acceleration, and he will fly further to unknown purpose. The hope that we will find evidence of such visits are extremely small. If civilization was able to create such ships, then she most likely understood (even we understand it), with what care should be taken in places where life was born, and tried not to leave traces (including in garbage). We are hardly lucky to discover the crash site such a probe, because they are most likely on their own repaired during interstellar flights, printing out the necessary details on a 3D printer. Course such devices are no doubt paving themselves: reaching another star, they scan planets for signs and lives and possibly create copies of themselves, which then scatter into different systems in geometric progression. Add to this the likelihood that civilizations, capable of launching such probes, several. In science fiction also considering the possibility that may appear “mutated” ships that begin to hunt for “normal”, instead of exploring the planets and reducing their numbers. Um, I wonder if it’s easy to catch someone in space … Contact whether the probes are with each other so that visits to the same starry the system is not committed too often? Aberration of light, probably could be overcome with the help of quantum entanglement, for us still exotic, and then all the probes would have known exactly each other’s arrangement. And if not, then in the visited star apparatus could leave a beacon to the system. Or maybe a universal visiting journal is being maintained – a giant galactic archive, accessible to any civilization that is able to pick up to it password. Most likely, such probes will not tend to contact with sentient beings, even if they can detect them. Maybe, the devices are programmed for some tests that allow to determine the intellectual maturity of local species, but not for the sake of communication with the latter. Dmitry Tselikov
