BS spewed the following BS

From jb, right on cue:

There is NO longitudinal component to
Gravitational Waves.

..An ad hoc ancillary tacked onto GR to keep it in conformity with the
'no medium' premise. Same with the 'speed of gravity' being c.

.... and you know this from your extensive and intimate knowledge of the
mathematical model of GR???

Please demonstrate for us were and how this "ancillary", "ad hoc" result is
tacked on to GR.


A fact, is it???

Yeah. And if it ain't, and space is a
"void", then we're stuck with "fossil fields", 'virtual gravitons',
virtual photons, angels, imps, and Sky Pixies. oc
