This story involves time travel, vampires, pastry, highwaymen, heavy metal music, black pudding and of course the meaning of life. Let's concentrate on time travel. Scientists, Einstein and chaps like that, say that time travel is impossible. That should prove to you that this story is fiction - made up stuff that you don't have to believe. You can laugh at it, be gripped by it, annoyed by it, no problem there, but there's no point in believing it, because scientists say it can't be true. Got that clear? Definitely not true...
