He proposed an unusual method for interstellar travel
The star system that is closest to us Alpha Centaurpeople to reach speed of light should use spacecraft moving with. But even in this case, it will take 4 years to reach the star system. This time indicator in the case of spacecraft that do not have the ability to move at the speed of light 10 times increase. But what if a natural cosmic object is used instead of an artificially created space object for space travel? In his new article, the American scientist spoke about how this is possible. It is possible that alien civilizations use the same method. The current technological capabilities of human civilization do not have the ability to carry out interstellar travel. People even still Marsda they were not. However, in the distant future, human civilization may find itself in a state of search for a new home, in which case the necessary planet may exist in another star system.
Houston Community Of the college I., a teacher of physics and astronomyrina Romanovskaya assumed in his scientific article that The sun red giant people are no longer when they are transitioning to a transformed cycle mandatory will have to be separated from the solar system. Thus, the Sun will destroy the Earth as a result of the transition to this period. However, it is possible that any alien civilization has already faced such a problem and used an unusual way to travel in space. According to Romanovskaya, it is not necessary to use a spacecraft for interstellar travel. Instead, you can use planets that move independently in space. It is possible that alien civilizations have used this method.
“I think that extraterrestrial civilizations may have used planets moving independently in space to reach other planetary systems, observe them and establish their colonies there,” Romanovskaya said. Even if such a planet does not have fertile conditions for life, the level of technological development of an alien civilization can create the necessary conditions on that planet. Planets moving independently in space are interstellar space objects and they have no gravitational connection with any star. Such planets may have moved beyond their star systems or formed as stars. According to Romanovskaya, there are four cases of the use of such planets by alien civilizations.
Scientists think that only the number of independently moving planets in our galaxy 50 billion may be close. Depending on how events unfold, in the first case, an alien civilization may use another planet close to its own. “I think it’s the source of the planets moving independently in space Oort found can be. Such planets can fall there. The same can happen in the native star system of an alien civilization, “Romanovskaya said. Romanovskaya thinks that the independent planet has passed as close as possible to our solar system in the past, and it is likely that this will happen in the future. Despite the remoteness of the area, such as the Oort cloud, a highly developed alien civilization may have reached it using an independently moving planet.
In the latter case, an alien civilization may have used its technological capabilities to bring such a planet closer to its home planet. And even if the planet involved in this case did not have fertile conditions for life, the technological capabilities of an alien civilization could realize the problem-free terraforming of the planet.
This is due to objects located outside the native star system of an alien civilization. “An example of such an object is located in the solar system Sedna can bring a dwarf planet called. The dwarf planet Sedna has a very long orbit. Therefore, its distance from the Sun. 76 AVfrom (Astronomical unit / 1 AV = 149,597,870 km) 937 AVvaries up to. The Sedna dwarf planet is an approximate complete cycle around the Sun. With 11,000 realizes. “With the necessary technology and enough time for preparation, such a planet can be used to save civilization,” Romanovskaya said. To do this, as in the previous case, it is necessary to draw the planet to the native planet.
As the star enters a new phase of its evolution, it turns into a red giant and expands. This means that some objects under it can be thrown out of the star system. In this case, they become independent planets. “If an alien civilization can determine when such objects will be thrown out of the star system, they can prepare in advance for these planets and take them out of the already endangered system,” said Romanovskaya.
Romanovskaya said that her offer All of his options include the possibility of using independently moving planets as a form of interstellar transport. That is, such planets should not be considered as a permanent abode of civilizations. However, according to the scientist, on the other hand, this or that civilization can use this mode of transport not only in the face of its own extinction, but also for a galactic journey to establish colonies on other planets. “If alien civilizations use this method, we can determine their existence. “So, these civilizations can definitely leave technological traces or other artifacts on those planets,” Romanovskaya said.
