<Snipped quote by Nimda>
Time is preemptive. It's time. If you go back and change something, you're just changing it to the state it was before you changed it but with new paint. If you kill your grandfather, you'll actually kill the person who used to be your grandfather who is no longer your grandfather because he died too soon. So you have a new grandfather who is exactly the same but looks/sounds/is called different.
Faster than light debatable.
Just avoid anything by someone called "Gia" unless you genuinely want me to spoil a whole arc/give you time to prepare. IE don't go look them up.
That's one theory. Again, it's impossible, so the only evidence is someone asserting that their speculation is the correct one to a problem that can't even be presented. That's why I have an IC solution to that.
Noted.
You also just argued that every person is predestined to exist. Gene combinations mean a lot in determining who a person is.
