If it is feasible, then this would raise the upper bound on the number of people who could eventually live by many orders of magnitude. On the other hand, given the Fermi paradox, its feasibility could be taken as evidence that humans are likely to go prematurely extinct.

There are a number ofMany difficulties that would need to be surmounted before humans, or any other intelligent species, could begin to colonize other star systems. For instance, there would be very largehuge energy requirements, the ability to manage extremely long (possibly intergenerational) flight lengths, and many distinct engineering challenges, such as the need to safeguardsafeguarding against high-velocity collisions with space dust.

Although there is not yet a substantial body of literature addressing the question, the small number offew scientists who have examined interstellar colonization appear to be on the whole optimistic about its long-term feasibility.

Space colonization is the establishment of self-sufficient human settlements outside Earth. In particular, effective altruism tends to focus on the possibility of interstellar colonization,Interstellar colonization is the establishment of settlements outside of ourthe solar system.
