David Spence asked the Naked Scientists:
My Question to the NST is
Is time faster than the speed of light ?
What do you think?
-
Time doesn't move at any speed. It's like asking if distance is faster than light.
The speed of light in a vacuum (about 300000000 m/s) is the fastest that any object, particle, or even information can move through space. (Note that speed is measured as the ratio of distance to time, so neither distance nor time can have a speed)
-
To talk of "speed of something" we need that "that something" is a space. If we want to include other things which are not space and define the "speed of A" as dA/dt, then the speed of (proper) time is always 1: dt/dt = 1.
