Gravitational waves from black hole merger

[paddoboy]

An accelerating charged particle radiates EM radiation, extending the same philosophy an accelerating mass, should radiate the Gravitational Radiation.

But then there is an inherent problem in this argument. Say, an electron in the orbit is accelerating (although QM has changed it all), so it must radiate the EM radiation and should produce decaying orbits and must collapse into nucleus...But it does not happen.

Exending the same philosophy, the earth also should radiate Gravitational radiation and slowly collapse into sun, there are certain unverifiable figures for this decay. But the problem is there is no acceleration in GR ? Kind of GR guys are falling back to classical Newtonian Mechanics to bring in the concept of force and acceleration and thus Gravitational Radiation. The Gravitational radiation and GW thereof, is more precsiely linked with angular momentum in this case.

It's a case of extent and size.
I'm sure its been told to you in the many conversations on this forum re the confirmation of GW's and BH's that they are difficult to detect and probably impossible to detect from the Earth.......Although GP-B did verify and validate the Lense Thirring effect.
They are real though.
Let me give you an example.....
Light and photons have no known rest mass...but they do have momentum, that has its effects as demonstrated with solar sails: And also light itself, due to that momentum, will warp/curve the spacetime in its vicinity, but by a teensy weensy amount......An amount we will probably never be able to measure....but just as real.
