More irrelevant psychological banter:
You have been asking "questions" since post 34: Some of those answers you have been given are subsequently ignored....other time the question is repeated and repeated again, probably on some vain effort to trip up people.
Let's get down to the nitty gritty: What are you proposing cosmologically speaking?
And what evidence do you have to support your conjecture?
Remember that Gravity/spacetime has a quality called "nonlinearity" In effect gravity makes gravity....That along with the fact that the gravity/spacetime curvature of a BH is a fossil field explains how gravity gets out of a BH.
Hawking Radiation is another matter: Virtual particle pair creation, [a foundation of quantum theory] near the EH of a BH, and the suggested scenarios leading to HR is a logical application> No we have not observed any as such, but again the basis is the foundation of quantum theory.
A great man said.
Spacetime tells matter how to move; matter tells spacetime how to curve.
John Archibald Wheeler:
If you are asking why does mass curve space time...and why does curved spacetime exhibit gravity, then the answer is
we do not know. Clear enough?
A future QGT may reveal the answer, but at this time all we know is that gravity and its association with mass and curved spacetime, is what it is, and we have been highly successful in making predictions and calculations that describe quite accurately what we see. We do that through the equations of GR, which have been continually confirmed to greater and greater accuracies via experiments such as GP-B and aLIGO:
Of course our resident cranks chose to disregard such confirmations in their evangelistic mission to somehow try and discredit such findings.
None of course get any further than forums such as this, open to all and sundry.
Let me finally reiterate:
No new cosmological theory of gravity or any other aspect of 21st century cosmology, will ever be forthcoming from forums such as this.
