The only thing that concerns me is that scientists have been looking for earth like planets orbiting nearby stars for some time now and all they have found are gas giants. No earth-like planets. I do realise that the technology is in its infancy and small planets like earth are incredibly hard to see (I am taking the vastnes of space into account), I guess it just depresses me. Limited technology and the lack of anything substantial within fathomable distances. Perhaps those Star Trekie things like worm holes and wrinkles in time and space are indeed plausable. I read somewhere (don't quote me) that the creator of Star Trek had some good ideas in theroy. Or was that Jules Verne? Again, don't quote me.
