"Star Trek - all versions of the series - have made admirable attempts to do the right thing within the laws of physics. And, where they're on the frontier? That's where the imagination of the writers and the creativity of the science fiction themes come in. But you can't undo the well-tested and well-known laws of physics that oughta serve as your foundation for what you're doing. Otherwise the whole thing just becomes fantasy - and you might as well just write a story no different from Lord of the Rings or Star Wars."
