Is a gravity wave also a natural expansion/contraction, but now in ~~sinus schape?

Or: what is the difference?

 no it is not sinuoidal that is a dipole wave, the quadrupole wave has 4 distinc polarity states two of which are 45 degrees out of phase with the other two. This is why the LIGO detector uses two arms in an L shape.

But it can be viewed sinusoidally, just using two points, can't it?

yes like two sine waves both simulatneous.

Cool. Is it emitted from merging black holes in a polar, conical fashion, like a GRB, or concentrically through 360o in all planes, or just in one plane? Popsci animations seem to show it radiating all around in one plane.

Gravitational waves travel through space, independently of the presence of mass.

In the new exibition of the museum Boerhave in Leiden (Netherlands) I saw the MiniGRAIL, a gravitational wave measuring device which prooved to be not sensitive enough. It was based on mechanical resonance in a copper ball. So gravitational waves loose energy in mass.
