Hi Michael
I just got back from the Ohio APS Nat conference where PM Robataille and Steve Crothers both delivered abstract talks. Here is an interesting paper from a talk by DT Froedge that was delivered in the same session entitled LIGO GRAVITATIONAL WAVES: RIPPLES IN SPACETIME OR ELECTROMAGNETIC.
The opening abstract from the paper at first seems to validate the concensus opinion re G/Waves.... which confuses me a bit as this is not the conclusion he reachs .... anyway I will add a link to the paper from his address at Vixra.Included also is a statement made by Thorne . Misner and Wheeler from 1973 regards the Energy Momentum Psuedo-Tensor, later recanted after 1975.
Dicke in 1957 [3], as well as others[4-9], have speculated on the possibility that gravitation has an
electromagnetic origin, and in fact it was only after the Pulsar Hulse, & Taylor [1,2], measurements that
there was a serious belief that the carrier of the energy, energy-momentum pseudo-tensor could have or
carry any energy at all.
It is notable that Misner, Thorne & Wheeler, Gravitation, 1973, p.467: remarked of the gravitational the
energy-momentum pseudo-tensor:
"It is not localizable. The equivalence principle forbids." "There is no unique formula
for it”, “it has no weight. It does not curve space. It does not serve as a source term ... It
does not produce any relative geodesic deviation of two nearby world lines ... It is not
observable." [11]
Belief in this changed after 1975 but, whether the measurements of gravitational radiation by the LigosVirgo
consortium are inherently gravitational or electromagnetic as still open. If the energy-momentum
pseudo-tensor is unable to carry energy then the transfer mechanism could well be electromagnetic.
Ligo Gravitational Waves: Ripples in Spacetime or Electromagnetic V2
Authors: DT Froedge
On Feb. 2016 the Ligo team announced the detection of gravitational waves from a collapsing Black Hole that occurred on Sept 14 2015. This definitively answers the question of the existence of gravitational radiation, and confirms the pulsar radiation energy measured by Hulse, & Taylor [1,2]. Although the loss of energy in orbiting binaries is indicative of radiational loss, it does not automatically follow that the energy being radiated is gravitational, there is the possibility proposed by several theorists, that the waves are electromagnetic [3-9]. The Ligo experiment has developed impressive measures to reduce electromagnetic signals, but at the levels of strain being measured, it is not certain that the momentum transfer can be completely avoided. Electromagnetic signals diffracted around the limb of the earth vs. gravitational waves passing freely through, yield timing and attenuation differences that can clearly distinguish between the two, but as of yet that has not happened. There can only be certainty when the three Ligo Virgo observatories simultaneously triangulate signals through the earth with proper timing and attenuation. This paper will explore the aspects of the measurements that will define the difference.

Cheers mate
