Time travel.

[Combwork]

Unless you believe in absolute predestiny; going forward wouldn't be possible as the future's not fixed; not happened yet but what about to the past? Changing the past changes the future, maybe you're family line dies out so you don't get to invent the time machine but does it? Two things cannot exist in the same place at the same time, but what if the traveler wasn't in the same time, but a nanosecond behind it? Never in exactly the same time and place as anything else; look but can't touch.

Alternatively, maybe people do go back and affect things. The past produces us, change the past and everything that happens from the change point onwards also changes. We're all products of history; change history and we change with it; no memories of what didn't happen. We think the past is fixed, except maybe, one or two mystics or the deranged get just a glimpse of the chaos; the boiling stew of possible futures.

I'm off to the pub or am I? Guess I'd better get there before I find out I'm not.
