> You know, I sure hope there aren't any far advanced civilizations out there. Because if there are, they probably will invent some sort of machine that will mess with time and stuff. And eventually, someone will use one of these machines to pause time, but then the machine will break, and the entire universe will be frozen. Imagine walking to your car but all of the sudden, because of some alien race, time freezes and doesn't become unfrozen. That's why I think that if we ever invent stuff that messes with time, it shouldn't actually pause time, but slow it down. That way, in case the machine breaks, it doesn't screw over the rest of the universe.

Actually, there would be no way for it to be unbroken. You hit the button, all time stops, there would be no way to hit the "Restart time" button. Also, speaking of going back in time, it would be impossible. Because, say, you go back in time to save yourself from some tragedy (Maybe you get in a car accident when you were young or something). You go back in time, save yourself, fine and dandy. You go back to your time, but the past you that needed to go back in time to save yourself won't, because they were never in the car accident. Therefore, the car accident would happen, so they would need to go back in time, but then they solve it, so the car accident didn't happen, so they don't need to go back in time, but then they don't go back in time and the car accident happens, and on and on. Now, if you went back in time and just looked around, that might work.
