I think all the time (this isn't a life theory, but it's cool to think about) about time being frozen, like right now, as i'm typing this, time could have been frozen for 1000 years, and then started back up and i'd never know a thing, you wouldn't know that time had been stopped or anything, and you'd just get on with your life, not realising you have been frozen in time for the past 1000 years.
Just a thought.
