The way Superman goes back in time in the movie might as well be magical because it doesn't conform to any science. Is he making a black hole? Nope he's flying around Earth. Is he going faster than light? Nope because we can see his trail, he doesn't have infinite energy, and the build up of mass would have destroyed Earth.
You have it backwards. There's more science fiction in his other abilities than being able to go back in time the way it was shown.
