But what we have here is "propagation velocity" not of "gravity waves"
but angular momentum. How fast (and how) do members of the Universe
communicate with it, since light is not the carrier of gravitation?
Is the Universe present at each point as some sort of remoted aether
or "proxy", or is it simply present at each point with only some
"flavors" diminished by distance? Mach would have an answer that will
yield a null result (I think) for any tool we could make.


What is a wave in space-time?
That is what they are looking for, isn't it?
A wave in space-time caused by some large wobbling mass?

I can certainly understand time going forward
more or less quickly but the idea of time going
in reverse is more difficult. Does a wave in time
have a positive offset, like a D.C. offset in electricity?

I can certainly understand space contracting or
expanding but the idea of gravity waves making
regions of negative space is more difficult.
Does a wave in space have a positive offset?
