I agree that a large generation ship capable of duplicating most of the conditions found on earth would be the only way to go. A large cylinder spinning so the colonists would walk around on the inside surface of the outer shell would seem to be the ideal shape. 10,000 people is probably a good number but I think only a few hundred would need to be scientists. Most of the rest would be ordinary people doing the same ordinary work they do here on earth. And like others said the second and third and so on generations would have no choice.Shpaget":26yssfwe said:duluthdave":26yssfwe said:A generational transport would benefit from being attached to an asteroid for the trip, and could make the launching of such a mission much simpler.
How (on both parts of quoted text)?
The problem I see with generation ships is that the original crew would likely be handpicked mostly from scientific community and would be composed of highly educated and capable (preferably in more than one area) individuals covering all fields of today's sciences.
Such ship would require a very large crew, my estimation is no less than 10 000 if the goal is to colonize another world (gene pool). While the Earth population could surely supply such a number, if 10 000 first class scientists suddenly disappeared from Earth it would leave consequences on our future researches.
The other thing is that even though these people would probably be very interested in the mission, chances are that their children will not share their enthusiasm and would feel they are being forced to do something they never wanted to be involved with, especially when they learn what their parents left behind.
If the trip takes only two generations, the mission might even succeed, but with every new generation, the number of people interested in sticking to the original plan will fall.
