I appreciate what you’re trying to get at, but it’s not right. Gravitational waves exist in GR even in theories with no matter / Higgs.

The Higgs is a scalar field; gravitational waves are spin-2.

Thank you for pointing it out.

Spin-0 particles are round particles, like o (like ball), or something that cannot rotate at all. Spin-2 particles are symmetrical particles, like 8 (like H2 molecule).

For spin-0, it can be changes in density only. For spin-2, it can be changes in orientation, in rotation speed, in rotation orientation, Dzhanibekov effect, wobbling, and some other if it has more complex shape, e.g. two spirals connected.
