Being realistic??? Not really. You're just throwing out half-baked ideas that have no logical reasoning applied to them. To say you're open to the idea of time travel means nothing. Being able to discuss it logically and base it on factual data requires a background understanding of physics and quantum mechanics, for starters. I doubt you could even intelligently discuss any kind of science at all that might suggest it's possible. You're one of those people who think you're as smart as anyone, but you reveal to those who are smarter than you that you're not.
