I just started thinking about it. Why is space exploration even that necessary? They're spending so much money on it when we have so much problems in our own planet..
Few things are more important than Exploration. In all avenues exploration leads to discovery which leads to growth. What else should we be working on? Cos atm the western world (which I inhabit) focuses most human effort on making 'line go up' and it feels entirely wasted and pointless.
