Struggling to find a way to phrase this question in a manner that doesn't fit into an 'idea generation' format and keep it on-topic in WB's guidelines. The question (with a bunch of caveats) boils down to why (or what motivation) humans would colonize a distant world fully knowing that contact between them and the Earth where they originate is near impossible (or take 10 years to send a message)? This would include knowing that the original colonists making the decision to leave would not live long enough to see the world they are to colonize, nor would their children, but their great great grandchildren would be the ones to colonize it.
Any idea's on how to write this question in a manner that isn't idea generation and keep it on topic? Or is it good the way it sits here?
It's easier to write this question as a what would society be like in such a format for the children / grand children that are forced into the transition lives between the two worlds...but I'm looking for a way to ask the motivational piece of what would encourage this send off.
