Aye, I know. I am not shocked by the distance either- and what I meant by 50 years was being able to try and survive on the planet, regarding that we are ready and have learnt that that specific planet can sustain our lifeforms. If we go together like a puzzle, if those so called extraterrestrials are like our missing link or a superior version of ourselves, maybe they do not wish to be found. It said there is a greater amount of radiation, so I'd assume that if any life is there it has grown to adapt to such measures, and we initially would not be able to physically cope without protection. I know we will reach it, yet I simply do not care for the fate of the human race after my death, good luck and all- but I would've moved on and it'd not be necessary to dwell over what I once lived with.
