It is very interesting how Fotini Markopoulou proproses an emergent space like if this space was not foundamental but arises from these quantum processes. If this locality due to these quantum prosesses permit the emergence, it merits attention about the real nature of this spacetime . It is challenging when we want to unify this QM and GR , so the small scales and this comsological scale, We could also consider these deep unknowns like the DE and DM, if these parameters are also a reality at this quantum scale, and that even a fifth force is a reality, that could permit extrapolations, if she is right about the fact that this space is emergent , that gives roads to better understand this quantum gravitaty maybe and correct the divergences.
Steve Giddings also explores relevant philosophical and ontological questions considering a kind of quantum theory of everything implying a TOE. What exists indeed and from what, it is the question after all ,what is a measurement, an observation , how must we interpret these measurements and what it implies for our deepest unknowns like this quantum gravitation. If we take his ideas , so this quantum gravitation has deep implications for the BHs and the nature of this universe at all scales, the planck scale like the cosmological scale, How to unify this QM and GR still and so G c and h ,This quadrupolar nature of gravitation spin 2 intrigues me , if the effects of the gravity at these smallest scales of lenght like the planck scale must be considered , so what is the solution in eliminating these divergences. Is it the key this graviton, quantas of gravitational waves, can we solve like this. I don t know if they exist really these gravitons to be franck,
Lucien Hardy and the indefinite causal structure also is relevant for the cause and effect sequences where the events have generally an order, but he suggests that at this quantum level this causality might not be fixed but indefinite like if these events were not well defined, it merits also attention due to this different approach than our clasical causality but not easy ontologically and philosophically and due to limitations physical also.
Sean Carrol and Alan Guth and their ideas considering the universe like a quantum object is relevant, I consider the same in my theory like if there are links between all scales, the spheres like you know being the founamental objects in my theory of spherisation, the evolution of the universe. so the universe and its cosmological spheres and the quantum mechanic and its quantum spheres have secrets to give us I believe. The volumes, the motions of these spherical volumes probably are important and there is a kind of logic and probably new constancts to find. That is why I loved their idea about the universe like a quantum object with its own wave function , it gives roads for the origin of the universe and if we have multiple universes or one and if the quantum multiverse also can be considered or one,, but if the quantum principles give the evolution of the universe, so I like this link because the evolution seesm essential, it is the meaning of my theory even the evolution spherisation of this universal sphere.
Thanks for sharing the ideas of all these thinkers, it was a pleasure to see , congrats to them.
