Throwing money at searching habitable planets that are light years away is what I'd call a terrible sense of what's a priority. We have immediate problems on Earth right now, like getting enough energy, contamination, millions of people living in poverty, and various illnesses that don't have a satisfactory treatment. Directing money and efforts to analyze objects that are light years away is complete madness, according to my subjective opinion.
Is there any concrete possibility of colonising another planet? Here in the comments for similar stories I see lots of scifi talk about the topic but little concrete arguments other than some amateur maths and physics. I know me some astronomy and even colonised Mars seems pipe dreams to me. Am I wrong?
