I've heard of this, but don't know what it is. Can anyone help me out?

You are stationary in an inertial ref frame (as first approximation you can take earth) and you analyze a very fast moving object which has a clock attached to it. You measure with your clock the time the object takes to go from point A to point B of your ref frame, call it Δt; you also take notice of the time interval measured from the clock on the object, call it Δt'. It results that Δt > Δt'.

Essentially, a clock on a moving object goes slower than one available to an observer in an inertial (unaccelerated) reference frame. It only really becomes noticeable above 0.9c, though.
From what I've read, it has to deal with going perpendicular to the fabric of space-time (sort of like black holes) and thus going "outside" of normal time.
