    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.

    Perhaps on paper but, not in the real world.

      That's why he has a Nobel Prize! So you can think it's gibberish.

      @@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.
