Overall, there are a variety of possibilities for ancient civilizations
to spread. After the final evaluation, around 80 spacefaring civilizations
will be added to the larger areas. Therefore, most of the space in the galaxy
is probably already occupied. Based on the data in this book,
you can make a rough calculation.
There could still be 5,800 to 10,000 uninhabited but living Earth-like planets in the galaxy. The average distance between these systems is then 1,360 - 1,700 light years. There could be up to 10 ancient civilizations in the galaxy. If each ancient civilization founded 100 daughter civilizations, that's already 1,000 systems. There are also 80 spacefaring civilizations. Rounded up, that makes a total of 1,100 inhabited star systems. Then each system has a scope or territory of 1,400 light-years radius. Our territory would contain 26 uninhabited living Earth-like planets, 124 inanimate Earth-like planets and 4,900 Earth-sized planets. At a civilization rate of 1 daughter civilization per century, humanity would need about 500,000 years to colonize all planets. If each ancient civilization founded 1,000 subsidiary civilizations, that's already 10,000 systems. There are also 80 spacefaring civilizations, each with a daughter civilization. Rounded up, that makes a total of 10,200 inhabited star systems. Then each system has a scope or territory of 675 light-years radius around itself. Our territory would contain 8 uninhabited living Earth-like planets, 26 inanimate Earth-like planets and 730 Earth-sized planets. At a civilization rate of 1 daughter civilization per century, humanity would need about 80,000 years to colonize all planets. This means that it will not be easy for humanity to have further-reaching or long-lasting expansion plans in the galaxy. The former Lockheed senior scientist Boyd Bushman stated that an alien race would live 68 light years away. But that means that aliens would already be living in our territory. Which suggests that large parts of the Milky Way are already populated. This means that humanity's expansion plans in the galaxy will not work under the most adverse circumstances because there is not enough free space. |
