It wasn’t easy for the first colonists to come to the new world, it won’t be easy for the first colonists in space. But in the long run humanity will be better for it. We have to take the first step, otherwise we never would have left Africa.</text><parent_chain><item><author>grawprog</author><text>&amp;gt;I think it&amp;#x27;s kinda cool to consider that rogue planets &amp;#x2F; brown dwarfs [0] could be candidates for extending human life beyond the solar system post-Sol.
