It's time & dimensional travel so the future and the past are always changing and in flux. Then I shall look at it that way too

After I posted my question I remembered an episode of Quantum leap where Sam leaps into one of JFK's bodyguards. He fails to prevent Kennedy's death, but Al tells him that in the original timeline Jackie Kennedy also died. Of course, in our World, she did not die, so we live in the world that Sam's actions created. But!! Did we always live in that world? Or did we live in the 'Jackie is dead' world and then Sam leaped back and stopped that so our world history, and therefore our memories, were instantly altered around us? Similarly, in Back to the future 3, when Marty arrives in the old west and Doc tells him he gave him explicit instructions not to come to rescue him, shouldn't Doc already have been expecting Marty and know why he came back to save him because it was young Doc who helped Marty get to the old west from 1955? Shouldn't Doc have that memory of sending Marty back to the old west?
This is why I love/hate time travel discussions.
Originally posted by: ricarleiteI've watched part of an episode for Dr. Who for the first time yesterday. It featured the tenth doctor, and on that part of the episode the doctor and Rose were locked with this lady on a room, and telling two other people how to get rid of an alien who was invading their apartment - a man in a rubber suit. They managed to explode the alien by throwing a mix of some oil and eggs on him, as the doctor quickly discovered what was the secret weapon... *sigh*
That's sort of the point of Dr Who, Ric. It's cheesy, tongue in cheek, rubber suit crap, but that's why people love it. It's a British thing.
