Gerard 't Hooft (Spinoza Institute and Utrecht University, NL) about "How quantization of gravity leads to a discrete space-time" at the Emergent Quantum Mechanics 2015 (EmQM15) Symposium sponsored by the Fetzer Franklin Fund at the Vienna University of Technology (Austria).
EmQM15 was the 3rd International Symposium about Quantum Mechanics based on a "Deeper Level Theory".

Dr. Ruth E. Kastner also argues for a discrete.... discontinuous ... nonlocal process

The gravitational field is space-time in the Planck system: F(G)/F(e)=Gm(pl)^2/e^2=1/α, that is, gravity~strong interaction. This assumption follows from the Schwarzschild solution: the gravitational radius (or Schwarzschild radius) is a characteristic radius defined for any physical body with mass: r(G)=2GM/c^2 Consequently: 2E(0)/r(G)=F(pl)=c^4/G=ε(pl)/r(pl): with indicating the mutual quantization of the mass (energy) and space-time: m(0)//m(pl)=r(G)/2r(pl)=n,where n-total number of quanta of the system; the tension vector flux: n=[(1/4π)(Gћc)^-½]gS ( const for all orbits of the system: n=0,1,2,3....). Moreover, the parameter r(0)=r(G)-r(pl)=(2n-1)r(pl), defining the interval of the formation of the system, at n=0, when r=r(G)=0 (for example, the state of the "universe" before the Big Bang) turns out to be a quite definite quantity: r(0)=-r(pl). In the area [(-rpl) - 0 - (+rpl)] there is an implementation of external forces, "distance": (-rpl)+(+rpl)=0 (≠2rpl). On the Kruskal diagram of the hyperbole r=0 corresponds to the true Schwarzschild feature, the features V and VI are not even covered by the global (R, T)- space-time and correspond to the "absolute" vacuum; then the singular areas above and below the hyperbolas r=0 can be formally treated as the energy source (external forces). That is, the frightening "true singularity" is actually a superconducting heterotrophic "window" between the proto-universe (the source) and physical bodies.

@@element4element4 I like Martin van der Mark and Gerard 't Hooft's paper "Light Is Heavy" - it corroborates B.G. Sidharth's claim that the photon has gravitational mass due to noncommutativiity. Sidharth predicted the dark energy acceleration of the universe - a year before it was discovered. So Sidharth should have gotten the Nobel Prize for that but because he's from India he was discriminated against. Yes 't Hooft and Penrose had a spat about Penrose's light cones for analyzing black holes - they use different math but they are really saying the same thing.

@@frun Causal set theory is just a variant of commutative geometry. The truth of reality is noncommutative time-frequency as Alain Connes explains, Field Medal Math Professor. Gerard 't Hooft understands this also.
