When will the stars with low livability colonize?

Not sure. The time for human beings to colonize these uninhabitable planets in the future depends on several factors, such as the development of science and technology, the acquisition of resources and the adaptation of the environment. Humans cannot directly reach other galaxies, even the nearest one. The planet with low livability among stars refers to the planet with low livability index in planetary parameters, that is, the living planet that is not suitable for human habitation or similar to life on earth.
