Yes, that is what I was trying to get at, I just didn't want to come straight out and say it because I wanted to avoid the black hole issue. So I suppose we cannot create something that can alter time and still allow us to survive. If we could I suppose that would be usefull, make its time distortion feild large enough to cover an area and you can have a civilization that will never die– or age for that matter– so I suppose you would have to find a way to send children to another "time distortion" planet which could let them age until a specific time and then they go back to the civilization. But that would lead to population problems ect... (pure scifi rant)
Oh, that brings another question I could ask, if you were to strip away all the objects that cause time distortion, what would the time be?
