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?
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.
