As one who hasn't got a clue as to what you are talking about.

But if I had to take a guess, I would go with a modified version of Einstien's Theory of Relativity & Gravity that led to the developement of QUANTUM THEORY MECHANICS 101.

I wouldn't be exactly sure of the modifications I would make to MY equations based on the fact, that the last time I heard Stephen say anything in this regard...I couldn't understand a darn thing he was saying.

I have only little knowledge from stephen hawkings book to recapitulate.eg In GRAVITATION there is a section when he and W Israel(both are authors)agree to head the chapter indicating some possible arrangement to unite Einsteinian-spacetimewithNewtonian spacetime. Its not actually achieved;we know he does not put his own view in it;he says so.
If the theory has to unite all physics(ie an ether harmonic inferring a view of a perturbed vacuum)then he has got problems himself. ie(maybe)from elsewhere off the internet we have to ponder latent rules according to some referencable proof amounting to a 'conditional set of rules ctrl an unconditional rejection of the present quantum mechanics'on offer.No one is sure what the final acceptable rules will be from the subnuclear atomists research into the boundary problem.
QUO VADIS? What comes from the Fermilabs and Cern is what will tell them.Save us then////
