    I can't begin to follow the math involved in anything relating to relativity, but I don't think you can think of time separately when talking about things at the fundamental level of gravity waves.

    Think of the ball on the rubber sheet depiction of how mass warps spacetime. Gravity waves passing through that depiction permanently alter it in some way. I couldn't begin to know how but I guess what they are getting at is that that than a sine (gravity) wave passing through, bending and returning to it's previous state, it leaves behind a change (an echo perhaps?) Being able to somehow see those changes would let the really bright folks theorize and prove some more things I don't understand.
