[Time Dilation] ... speed = distance / time

Katherine, This is a pretty good explanation of the process for an enthusiastic laymen.
As I understand it, it has to do with the speed of light being constant regardless of the motion of the observer. In order to experience the speed of light as a constant, regardless of the observer’s motion, time must become a variable in situations experiencing drastic forces due to acceleration or gravity.
Speed = Distance/Time since C (the speed of light) is constant, as is Distance, the variable of time must shift.
Someone who gets this better than me should really explain it, but I thought I’d take a crack at it just for the hell of it.
