This is for the benefit of those who can learn - the linearized
version of general relativity is not cosmologically applicable as the
assumption is that the manifold is Minkowski plus a perturbation,
which is obviously not the case for FRW cosmologies.

BZZT, wrong. The linearized equations do NOT look like Proca's
equations.

BZZT, wrong. The graviton is spin two.

Sure - respond to my trite one liner instead of the legit points.

Ahhh.... but try writing a set of linearized field equations that are
lorentz invairant, too... gravitoelectromagnetism doesn't just fall out as a
natural consequence...too bad.
Are equations for London forces Lorentz invariant?

Hello again imbecile. Why don't you give up demonstrating your
stupidity?
Spin-1 graviton couples to everything but not to itself, while a
spin-2 graviton couples to everything and to itself.
Spin-1 gravitons are graviscalars or graviphotons. There is also the
spin-3/2 gravitino. These particles result from supersymmetry. Spin-2
graviton is a bound state of two spin-1 gravitons.

A set of gravitomagnetic and gravitoelectric forces can be derived from Van
der wall forces? As far as the articles you cite, especially the physics
world article, perhaps symmetry breaking is what is being measured with
spinning superconductors. It's an exciting possibility if true - I really
wanna buy a Jetsons gravicar.
