An expanding civilization can quickly spread throughout the galaxy and therefore the likelihood of contact
American scientists have proposed a new explanationthis paradox. Scientists believe that alien civilizations are probably looking for certain types of stars for expansion and the solar system does not meet their criteria.
The authors of the study point out that allprevious simulations assumed that stars were equally valuable for expansion and took into account only the probability of formation of planets around them with suitable conditions. The researchers believe that alien civilizations would rather prefer K- and M-class dwarfs than stars like the Sun.
Compared to yellow dwarfs, such starsmuch more stable and long-lived. Although this is not important for humanity at the current stage, a civilization capable of colonizing planetary systems will take such factors into account, scientists say.
Regardless of the stage of development of civilization,attempting to colonize a planetary system would require the allocation of a large amount of resources. Therefore, a civilization that has a choice will not put its resources on a star that disappears first. Even if that "before" is millions of years, the scientists explain.
If the theory is correct, then right now in the Milky Way there may be civilizations that are gradually mastering clusters of long-lived stars and do not intersect with us.
