Spaceships are not needed: scientists proposed to travel on rogue planets

Instead, they can use free-flying planets, also known as rogue planets. It is possible that

in the Milky Way or in other galaxies, there are rogue planets where life develops, which lives in subsurface oceans heated by radiogenic decay.

If a rogue planet meets a star and they havea gravitational bond is formed, then it will begin to rotate around it. This means that the life that is on the rogue planet, falls into new, perhaps more habitable conditions.

There is an idea that rogue planets are dark, cold and life cannot appear on them. This is true, but with the exception of those objects that have warm subsurface oceans.

The authors of the work stated that if humanity does notcan continue to live on Earth, then you need to find other objects on which you can continue the race, or figure out how to organize a trip over vast distances. It takes more than four years to fly to Alpha Centauri at the speed of light.

Therefore, it is potentially possible to moveuse rogue planets. In 2021, a team of researchers announced the discovery of between 70 and 170 rogue planets, each the size of Jupiter. And in 2020, one study suggested that there could be up to 50 billion of them in our galaxy.
