i don't mean to take over the forum by starting a zillion threads, but we got into a pretty interesting digression over on the ‘alien civilizations’ thread about space colonization, so i thought i’d open the topic up into a general forum discussion. so, is space colonization possible? if so, when? how would it be done? moreover, what would this mean for life on earth? personally, i think the moon will be the first to be colonized in a few centuries, using some method of terraforming. i think space colonization will be beneficial in case some catastrophe were to strike earth, and also provide extra resources like water and minerals, and prob also boost the economy in terms of space tourism and real estate. what do you think?
