Hmmm I've always thought that to be able to travel into the past the past would have to exist as an objective reality, likewise with the future.Â
Personally I've always doubted whether that's true....I think the past is only present in our memories and in a very subjective state at that, oh and also in the intitial conditions which make up the present but that's kind of a memory too. The future of course doesn't exist yet...only its possiblity.
So I don't think that its possible because it's a nonsensical proposition....Of course I'm probably completely wrong and we're surrounded all the time by time travellers on package holidays to this, a golden age in western history
