Generally, when astronomers and astronauts and all various sorts of scientists who are looking for habitable living spaces, we look for those that imitate Earth in some meaningful way. We want potential living candidates to have comparable revolution periods, temperatures, day length, and overall be as comfortable as our current living conditions.
According to physicists at the University of Texas at Arlington, F-type stars may “indeed be a good place to look for habitable planets.” This comment in itself strikes an alarm bell due to its unusual nature, as F-type stars tend to be in the middle of the stellar scale, and are more massive and hot than the Sun, certainly not a livable habitat. On top of these already non-bearable for human characteristics, F-type stars also emit much more ultraviolet radiation, which could also sustain life heavily.
All in all, the researchers decided to take this bold stance on the issue due to the overall lack of knowledge on the issue, which leads us unable to fight back without doing extensive research to the topic which could simultaneously benefit or hurt either side. What is also postulated is that due to the lack of knowledge on the issue, that there is a much wider habitality range in F-type stars as opposed to other stars or planets. It is always interesting to take a stance that suggests that we look not for answers, but to find more knowledge, which leads us to more questions and yet to more to study, with more depth and more fervor. It would be interesting to hope this is the case because if so, we may find more habitats in our world, on other campuses, and in space. This would open up infinitely more moral questions as to who deserves to live in space, as well as the inherent race separation that would arise from living or separating off into distinct groups in space. However, this is the case with any real technological developments, and dreaming that we are ever free from moral decisions is an illusion at best.
