could two copies of Pati-Salam gauge group work in providing one SU(2)R for gravity and the second copy SU(2)R reduce to U(1)Y

could the U(1)Y hypercharge of the standard model perhaps be tied to the Immirizi parameter in Ashtekar gravity, or perhaps be a chiral feature of Ashtekar gravity, or added ad hoc to Ashtekar variables? isn't Stephon Alexander proposal, which uses the chiral aspects of SU(2) and joining...

this thread is to open up discussion on Gravi-GUT as theories of everything GUT or Grand Unified Theories attempt to unify the 3 forces of weak E&M and strong force, and Gravi-GUT want to add gravity. this peer reviewed paper in a journal on Gravi-GUT Chirality in unified theories of gravity...

so any cosmologists here can explain the status of quantum cosmology, and its leading candidates?

what is the current status of the field for quantum cosmology, are there any observations that support any theory of quantum cosmology? is it just cosmology during the Planck era or does it extend past the Planck era. what are the leading candidates into research into quantum cosmology and...

On the Quantum Mechanics of Entropic Forces Daniel Carney1,*, Manthos Karydas1, Thilo Scharnhorst1,2, Roshni Singh1,2, and Jacob M. Taylo DOI: https://doi.org/10.1103/y7sy-3by1 discuss further details about this could spin foam also work ?

how does https://arxiv.org/pdf/2503.09804 compare with Deur's work

what do you think of Deur's work, is it credible or handwaving?

could you either change the dimensions of the lattices, or change the nature and properties of the lattice, such as spin networks, or use a topology in 4d space-time to get powers of 3 A Lattice Physics Approach to Spin-Networks in Loop Quantum Gravity Noah M. MacKay

could you elaborate on this other way to quantize the Ashtekar variables hat might give us an inkling of the right way to think about "quantization of space-time?

you omitted has there been any research, suggesting that spacetime has a lattice like structure, and that the origin of three generations of fermions in the standard model is in the fermion doubling problem, the three generation copies is in fermion doubling that is a question

I was asking a question

"All of the cited known examples of doubling give the number of fermions to be an integer-power of two (0, 2, 4, or 16 total)." perhaps instead a simple 4D lattice, try a 3D spatial lattice to get odd

from the article if successful eliminate, with some consisting of a doublet, or a quartet of fermions perhaps there's a resolution that gives you 3 generation and only 3 flavors, either a combination or new theory gives you 3 generation
