Right, so... Do gravitational waves theoretically travel at the speed of light? I studied physics way back in the 90s, I recall the universal gravitational constant, I don't think gravity waves were a thing yet. I'm just trying to get an idea of the wavelength.

Edit: Yes, they are theorized to be light speed waves with a potential wavelength spanning the entire universe.

Shit like this makes me regret changing majors. I miss thinking about the fundamental nature of reality in mathematical terms.

Yes, that's correct: Gravitational waves travel at the speed of light.

Yeah I had to look it up and now recall learning about the theory! Funny what a brain forgets. My brain at least.
