Thank you Steven for you reply.
you said........
The mechanism is straightforward. Like other bosons such photons and gluons, gravitons are created by local gauge transformations so that the Lagrangian is invariant under the symmetry rotation.
I'm surprised you are unaware of this.
Aware but not handy in application...are we not simply talking of the mechanics the standard model uses as opposed to what I was after (I guess ) being...what is the force in action our graviton conveys.
You also said........
Gravitons have no mass. So there is no problem of escaping, no anomalies.
I thought a photon was without mass and yet they do not escape our black hole so saying a graviton is mass less does not solve the anomaly in my view.... so I must still be missing something

.
Hopes this makes thing much clearer.
Oh by the way gravitons haven't been observed and mess up the mathematics.
Coincidentally push itronswhaters have not been observed either so that must be handy if one wishes to capitalize upon presenting a new "theory".
Steven I thank you for trying to make things clearer I really appreciate what you and all the others here do to help me learn a little physics... I read but without a teacher it is hard to be honest...and being an old man does not help... again thank you sincerely.
