FTL or faster-than-light travel is currently unachievable even in particle accelerators. There you have it. A huge rotating and thickly shielded space station ring might work, but every ounce of shielding has to come from somewhere. That is, its cost in terms of scarce resources is quite high.

The takeaway for me is that ó except perhaps for (ugh) military goals with their potential for widespread damage to things on the earthís surface, space exploration is best left to remotely operated machines.

An important thing is not to become a fool. Idealism is great, but itís hard to make it work in this really messy world on the large scale. Its like immediate family versus the outer world. They donít mix. Whatís right for one is wrong for the other. Iím well aware of the absolute need for military defense. Once, a good man even more of a pacifist than I, said to a bunch of antiwar young guys as a flight of Air Force jets roared overhead, ďThere goes our protection. Donít forget it.Ē

Space opera? Bah, humbug! For now, and quite a while, at least for civilians.

That's why its so important for me that science fiction should be remembered as fiction, and as more about its characters, its metaphors, its plots, than its science. You are of course totally right; so I think I look to science fiction (and fantasy) for the same things I look for in poetry, imagination to reflect our condition in new ways.

Your quoting my every word is great protection against my deleting something pithy. Thatís a smile you are imagining.

I have a relative who is important to me and probably doesnít read Eratosphere posts of any sort, yet who is a dedicated writer of imaginative fiction set in the future (sci-fi or fantasy). Were he to read this thread, he would likely get very angry with me, and possibly depressed that I turned away from one of his greatest pleasures. Thereís a silver lining for me: we arenít in direct competition. Hats in the air about that !!

Iíd add that future fiction with extraterrestrials (even human ones) offers a safe ďspaceĒ for writers to populate with villains of various sorts. Our world is so interconnected now that off-planet may be the only milieu where one can safely write about (and derogate and demolish) bad evil awful ignorant nasties with impunity.
