The planet designated Kepler-186f, however, is earth-sized and orbits within the star’s habitable zone. ................................ Well I guess there isn’t a rush to go buy property there at the moment. I guess when we run out of oil, we’ll have to look for it there. I’m sure we don’t have to rush, its only 500 light years away. I’m sure as the years go by there will be many more livable planets found. At the same time, someone or something out there may be looking at our planet for the same reasons we are looking at theirs.
Ridicules comment. Are you suggesting exploration, observation, study and research for earth similar planets, other life, etc be stopped or is somehow nonsense?
Future inhabitants, our species on this little planet have more to worry about than running out of oil, since this planet and our sun have a shelf life which will leave earth a burned charcoal cinder or just vaporized.
Should exploration be given up because with current existing technology, they're too far away to get to or communicate with? I don't think so. There is a whole lot more we don't know than we do know at this point.
Man stays here and eventually man's time ends here. There will be no need for oil, water, history of man or anything else.
