...like in the movie Clockstoppers (and other stop-time-movies), when they activate the device they're able to slow down time or stop it all together.
...but they're still able to move around. Okay, if they stopped time and everything around them comes to a stand-still, wouldn't they be frozen, too?
The air is filled with atoms and molecules. So if you stopped time, these would freeze in place too. It would be like they were standing in solid air. They wouldn't be able to reach their devices again to make time go normally.
Just the kind of stuff I think about.
