Warping spacetime
« on: 25/09/2014 19:56:09 »
If the density of mass can curve spacetime then a hemispherical shell of condensed matter should concentrate this curvature both on the external surface and the surface of the interior open cavity. If we have a series of such shells then the spacetime between the surface of one and the partial cavity of another may be one place where gravitational waves could be detected.

That's not true. The only time you're going to observe gravitational waves is when they exist and they can only exist when there's a time varying distribution of matter, but that's not what you have.

You do if the surfaces are not uniform and spinning in opposite directions. It also depends upon the size and density of the masses involved. The surface configuration would need to be engineered in a certain way to enhance the waves. Like an amplifier. I don't know if this is possible.
