[igrav-steering] Fwd: [igrav-announce] The problem on stationary states in self gravitational field

Maybe on a longer timescale, we should also think of how we'd like to 
deal with this kind of posting... That person is registered to the 
mailing list whose current settings allow members to post directly => he 
followed the rules.

Cheers,

It is believed that according to the General Theory of Relativity (GR), 
systems with variable quadrupole or higher multipole moments can 
generate gravitational radiation. Under this assumption, the power of 
the corresponding gravitational radiation is proportional to the 
quadrupole mass distribution tensor of the radiating system /Qij/, and 
the constant /G/ (Newton's gravitational constant), that is included in 
this dependence, gives the order of magnitude of the radiation power. 
The illegality of using this formula is not in the use of the quadrupole 
approximation, but in the calculation scheme. The system can emit only 
in certain quantum states, and this applies to any radiation, regardless 
of its nature. This is an axiom of quantum mechanics, as well as the 
existence of an elementary source of radiation having these states. 
Consequently, the theoretical prediction of the spectrum of 
gravitational radiation requires evaluation of quantum states, 
transitions between which cause radiation.
