Star Trek is science-fiction, and science-fiction, to a large group of people, is part of the awe and wonder of the universe. We speculate about what’s out there, and since we have no way of knowing, anyone’s speculation is as valid as anybody else’s. But it is of interest to people who look at the stars at night and wonder what’s out there and whether little green men are flying this way. Could we possibly see life? That brings up the question of death and all the stuff that we have no answers for. Science-fiction speculates an answer, and that, I think, is the fascination.
