This latest observation of gravity waves has brought up a question with me..
Since gravity is a mass-caused distortion in space-time aren't these waves wave distortions of the space-time?
I know there is no such thing as ether but for this analogy and my simple mind I'll use it to illustrate my question. If I think of the universe as being filled with this stuff called space-time (4 dimensional) (I know it's not "filled"...the universe IS space-time) then it makes sense to me, in trying to understand waves, that the space-time distortions propagate just like they might through water, the difference being that instead of water the "medium" is the 4 dimensional grid we call space-time. Is that close?
And if that is true, and since the first three dimensions do not seem to distort with mass, is it then true that it is the time dimension component of the 4 dimensions that is doing the distorting?
