SETI again

the reason that i would expect them to wait so long is that if there
is more resourse still in the solar system, there are likely places
where a new station could be built. this would put the new one far
enough away from the older station as to make it effectively as cut
off as going to a new star.

building a star crossing colonizing ship would be an extreamly
expensive undertaking. unless all the colonist were exceedingly rich,
its unlikely they could afford to finace it themselfs. If they cant,
then they will have to have some form of finacial arrangement, which
would likely be something along the lines of sending resourses back
to the home system. the only other way is that they become vertual
slaves for more than a generation to the company that is going to
build the ship for them.

at this point we dont know if all the stars have rings of asteroids
or planets around them. the only things we know of yet is the giant
planets like jupiter or saturn. Atleast in the early stages, they
would have to make sure there were materials needed for colonization.
