A new study has indicated that our solar system may not include the elements that attract other alien civilizations, so so far we haven’t visited one, if any.
This study addressed the “Fermi paradox”, developed by physicist Enrico Fermi in 1950, which suggests that if there were rapidly expanding alien civilizations in the Milky Way, they must have visited our solar system. If you don’t visit it, then it doesn’t exist.
The study, published in the Astrophysical Journal, believed that alien civilizations preferred low-mass stars, especially dwarf stars, as they are not attracted to all types of stars.
The study showed that alien civilizations will avoid high-mass stars in order to extend their life in the galaxy.
The study found that measuring stars based on their longevity is not a given for humans. If one type of star lasts 10 billion years and another type lasts 10 trillion, what difference will it make in people’s lives? But that’s different from the perspective of an alien civilization that’s over a million years old, for example.
Colonizing another solar system requires a lot of resources, so these civilizations will move away from stars that don’t live for long periods.
