Re: Questions about gravity and vacuousness...
The wikipedia link mentioned:
as the waves reach more rarefied air at higher altitudes, their amplitude increases, and nonlinear effects cause the waves to break, transferring their momentum to the mean flow.
... which despite not referring to the type of gravity waves discussed on this thread, does remind us that unstable waves are nonlinear waves, and nonlinear waves may mean waves that break. What happens when gravity breaks? I guess it creates a discontinuity or border of sorts. If gravity is the binder of all reality, then unstable gravity waves may have something to do with realm border waves.
A: Gravitons are really electrons within a time vacuum
Probably the most important and useful technical clue I have ever found in the Cassiopaean material.
