If you can change the laws of physics, you come close to playing God and that is, of course, the ultimate as well as the first sin. I suppose if one looks at science fiction as allegory of a spiritual type one could justify what I would regard to be a blasphemous appropriation of the Providence of God.
You could take the next step and say that fiction is ‘lies’ and inherently sinful, the Puritans thought so I think? (the difference is that fiction doesn’t claim to be ‘true’) Someone like Wagner fully admitted that his operas were an attempt to replace the reigning Judeo-Christianity with the older Norse Pagan ethos.
