But in general I agree with you -- the amount of time required probably means no self contained vessel could possibly last, even one that is essentially a hollow world.If there is ever such a thing as an interstellar drive, I think it is going to have to be some form of a warp drive (which while technically possible, the energy requirements make them both unfeasible and really, really dangerous for the area of space you end up in).</blockquote>
