I recently re-watched the 1st Futurama movie, Bender's Big Score, which has a heavy time-travel theme. The time machine featured, is not a man made creation, but a universal code that can travel through time. Built into this code is a method of correcting paradoxes. This is usually done when a characters travels back in time to meet themselves, at the point, the individual who went back in time is often killed in a bizarre accident that "corrects" the paradox of two of the same individuals at the same time. Do you believe that paradox correction is possible? If so, is it a good idea, or unnecessary?
