If, say, two "traveling" grav. waves run into each other, can their "collision" be constructive and/or destructive, or neither?

Well, if they're waves, why wouldn't they 'interfere'? By the way, 'gravity waves (http://en.wikipedia.org/wiki/Gravity_wave)' are something different. It's gravitational waves (http://en.wikipedia.org/wiki/Gravitational_wave) that are "fluctuations in the curvature of spacetime."

I meant the latter gravitational waves.
One of the reasons I asked is that if/when they are confirmed, we may not know how "pure" they are (e.g., BB plus other GWs interfered with -- say, constructive interference may result in deceptively large GWs).
