So the interior is real. Physics aught not get all Hegelian or Logical Positivist or whatever and say what cannot be observed is not real.

@1:05:00 't Hooft sketches the same idea, but done more rigorously by Turok and Boyle to answer why the cosmological constant value is so small. Neil Turok and Latham Boyle have found it *_is_* indeed a bit like an inverse of a large number. Performing a Lorentzian path integral and continuing analytically to complex time the entropy of the universe drops out as S=1/Λ (due to gravity the Hamiltonian contribution is zero, or exp(H=0)=1). Since our universe has a lot of matter and radiation is has sizeable entropy, and the most probable universe out of any ensemble is one with P∝exp(-1/Λ) close to 1, so Λ small. This Turok & Boyle result is not a causal account, since it's just statistical mechanics on an imaginary ensemble of possible universes, but a clue about what the source of Λ is. Turok describes it in an analogy as "like a chemical potential for spacetime volume." i.e., energy gained/lost by adding/losing one chemcial species, in the case of gravity that'd be the energy gain/lost on adding/losing an element of spacetime volume. Which is really, whe you think about it, the prosaic normal "explanation" for Λ, which is vacuum energy density. The source of vacuum energy density is the Planck scale topology. That's the answer. We do not know what it is because no one has developed a Planck microscope. ((They aught to find the Planck observatory in it's current graveyard orbit, bring it back down to the lab, hold it dead steady and just look down the other end in reverse.))

Black holes are finite systems. Finite stuff goes in and finite life span. The virtual infinites come from the time distortion factor like you said. Shwartzschild for time slicing and particle type mapping. Kerr for G-flows and hyper surfaces. The universe another cutoff point for black holes. R=0 could be a virtual particle. Though CERN has a prime candidate in the particle zoo. Specific particles can live in specific energy density regimes. BEC particle perception and superfluidity. C*periodicy. C*D complete. The universe decayed out to photons and the size then. When time losses meaning. Double the decayed universes size, and put one next to the other almost touching. Then rewind to current time frame and you get a big distance for a probabilistic universe. The universe is a finite system with solution sets. Quantum tunneling to a lower energy state. Predicting where hawking particles show up. Gravitational waves and particle production from quantum foam. Boundary layers that are also censorship layers. The last stable orbit of a electron in a specific energy density regime. Neutron star calculations and degeneracy. Energy conserved. Wormholes have problems with Paulie discrete energy levels. No fermions. Glad to see someone explain things most miss or start running off into some deep end. lol The black hole to another universe would show black holes shrinking or growing at random.

20:34 Root cause analysis. "The geometry of space in general relativity theory turned out to be another field, therefore the geometry of space in GR is almost the same as the gravitational field.” (Smolin). In "GR was QG" there is no problem with empty (~ geometric, mathematical) space-time, since the real variable gravitational field of any physical object is identified with the phase space. When 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**. P.P.S. As a fundamental theory, GR has the ability with just one parameter: r(G)/r=k to predict, explain new physical effects, and amend already known ones. Photon frequency shift in gravitational field Δw/w(0)=k; the angle of deflection of a photon from a rectilinear propagation path =2k, the Newtonian orbit of the planet shifts forward in its plane: during one revolution, a certain point of the orbit is shifted by an angle =3πk, for a circular orbit (eccentricity е=0); in the case of an elliptical orbit - for example, for perihelion displacement, the last expression must be divided by (1-e^2). ------------------- *) - GR/QG predicts a new physical effect: w/w(pl)=k; expression for gravitational radiation from a test body. This is amenable to physical examination in laboratory conditions at present. **) - From this, generally, from Einstein's equations, where the constant c^4/G=F(pl), one can obtain a quantum expression (as vibration field) for the gravitational potential: ф(G)=(-1/2)[Għ/с]^½ (w)=-[h/4πm(pl)]w. Final formula:ф(G)=-[w/w(pl)]c^2/2, where ф(G) - is Newtonian gravitational potential, r(n')=nλ/π=(n+n')2r(pl)l , the corresponding orbital radius, w - the frequency of the quanta of the gravitational field (space-time); - obviously, the quanta of the field are themselves quantized: λ=(1+n'/n)λ(pl) = 2πc/w, where n'/n - system gravity unpacking ratio, n'- the orbit number (n'=0,1,2,3…). Obviously, on the horizon [r=r(rG), n'=0] the "door" is closed, however, the quanta [λ=λ(pl)] can go out singly and form the first and all subsequent half-orbits (n'=1,2, 3 ...) during the time t(0)=r/c=2nт, where т=1/w, т=((1+n'/n)т(pl), spending part of their energy on it each time. And it is this mechanism that provides the step-by-step formation of a variable gravitational field: variably accelerated expansion of spacetime as a phase space: |a|=g=πc^2/L, where L is the length of the phase trajectory (of course, the quanta coming through the "window" are also rhythmically restored). The phase velocity of evolution v'/π= r(pl)w/π; m(0)=(c/2G)rv', where v'=v^2/c. The angular momentum: L(p)=|pr|=n^2ћ [const for all orbits of the system; at n=1: L(p)=ћ] and moment of power: M(F)=dL(p)/dt(0)=nћw/2=-E(G)=E*, where t(0)=r/c, E*- energy of self-action. According to GR / QG, gravitational field [E(G)=-E*] is characterized by a spontaneous flow: J*=(v'/π )(1/4π) g^2/G, where v'/π- phase velocity of field evolution. Entropy (here: a measure of diversity/variety, not ugliness/disorder) of the system: S=πε(pl)r(t)=(n+n')k, where k is the Boltzmann constant. Obviously, on the horizon entropy=min and with fundamental irreversibility, information is preserved (+ evolves, accumulates). Accordingly, m=m(pl)/(1+n'/n), where m=ħw/c^2, is the quantum of the full mass: M=n'm [

@@niblick616 "The geometry of space in general relativity theory turned out to be another field, therefore the geometry of space in GR is almost the same as the gravitational field.” (Smolin). In "GR was QG" there is no problem with empty space, since the real variable gravitational field of any physical object is identified with the phase space. Consider a special case: the Universe. Expansion is a special kind of motion, and it seems that the Universe is a non-inertial frame of reference that performs variably accelerated motion along a phase trajectory, and thereby creates a phase space (according to general estimates, this acceleration is: a=πcH)*. Real gravitational fields are variable in space and time, and we can now talk about the fact that it is possible to generate a gravitational field in a non-inertial frame of reference (|a|=g).That is, finally achieve global (instead of local in GR) compliance with the equivalence principle. Then the energy density of the relic radiation, that is, the evolving primary gravitational-inertial field (= space-time): J= g^2/8πG=(ħ/8πc^3)w(relic)^4~1600 quanta/cm^3, which is in order of magnitude consistent with the observational-measured data (about 500 quanta/cm^3). P.S.You can also use the Unruh formula, but with the addition of the coefficient q, which determines the number of phase transitions of the evolving system for the case of variable acceleration: q=√n'=λrelic /√8λpl , , where n'=L/8πr(pl) is the number of semi-orbits; L=c/H, is the length of the phase trajectory. Thus, T*(relic)=[q]ħa/2πkc (=0.4K), which is in order of magnitude consistent with the real: T(relic)/T*(relic)=2,7/0,4=6,7. {However, there is no need to have a factor of 1/2π in the Unruh formula in this case.} ------------------- *) - w(relic)^2=πw(pl)H, |a|=r(pl)w(relic)^2 =g=πcH, intra-metagalactic gravitational potential: |ф0|=(c^2)/2(√8n')=πGmpl/λ(relic). m(pl)w(pl)=8πM(Universe)H; { w(relic)^2=πw(pl)H. From Kepler's third law follows: M/t=v^3/G, where M/t=I(G)=[gram•sec^-1] is the gravitational current. In the case of the Universe, I(G)=MH=c^3/8πG (~ the "dark energy" constant). n' =4,28*10^61; w(pl)=(√8n')w(relic)=8πn'H; where H=c/L. H=1,72*10^-20(sec^-1). By the way, it turns out that the universe is 1.6 trillion years old! The area of the "crystal sphere": S(universe)~n' λ(relic)^2~n'S(relic). r=2.7*10^29cm, L=2πr. The phase velocity of the evolution of the Universe: v'=πcr/L=c/2, where c=√2(v): the "second cosmological velocity" in relation to the proto-universe. {In general, the masses of galaxies should be estimated as follows: M=(c/2G)rv', since the evolution of the system makes an additional contribution to the overall picture, and thereby clarify the problem of "dark matter".} Addition In an arbitrary non-inertial reference frame, the equation of the total mechanical energy of a particle system is: ∆E=A(internal)+A(external)+A*, where A (internal) is the work of internal dissipative forces, А(external) is the work of external non-conservative forces, А* is the work of inertia forces. In order to preserve the mechanical energy of the system in a non-inertial frame of reference, it is necessary that ∆E =0, however, in an arbitrary non-inertial frame of reference, it is impossible to create a condition for fulfilling this requirement; that is, ∆E does not =0 in any way (by the way, in system C, the condition for fulfilling the laws of conservation of momentum and angular momentum does not depend on whether this system is an inertial or non-inertial frame of reference).

@@niblick616 In fact, the observer's self-esteem in QM is underestimated to the level of the infamous ostrich. The observer is always involved in an unavoidable measurement process. It seems that there have never been any problems with QM already within the framework of GR (for example, in the case of the Schrodinger/Carroll cat). A live cat breathes and, accordingly, emits gravitational waves according to the formula GR with intensity: I(G)=(2G/45c^5)(M^2)(l^4)(w^6), where M is the mass of the cat, l is its characteristic size, w is its frequency breathing.The frequency of gravitational radiation should be on the order of w~ 2π/т where т is the characteristic time of accelerated mass movement (pulsation, rotation, collision, non-spherical explosion).It is clear that the dead cat is not breathing and I(G) =0*. In principle, all this lends itself to a certain (improbability) constant measurement without opening the "black box", since gravity is not shielded [w=w(m)]. Moreover, the behavior of the radiation source is also controlled, since it emits only in an excited state. ** Of course, Carroll's sleeping cat breathes, but differently (can be measured) than the waking one.*** Sweet dreams to you QM, on the interpretation of the Born wave function. P.S. Why didn't Einstein use this argument? He wasn't sure about the reality of gravitational waves and assumed only the presence of hidden parameters… --------------------- *) - By the way, a "smile" without a cat can be detected according to Einstein's equations. Raising one of the indices, substituting I=k and summing, we find: R=-(8πG/c^4)T, where T=T(n) is the trace of the energy-momentum tensor (~ "gravitational memory."). **) - If the cat is replaced with a detector, then with each absorption its state will change (which makes measurement possible). It is clear that this will also cause additional radiation of gravitational waves, since the included detector is already a source. ***) - The formula can be given in the following form for a photon: I(G)={[w/w(pl)]^2}ħw^2. Of course, this approach is also applicable to the case of entangled particles. "When physicists offer metaphysical explanations for physical phenomena, I start swearing." (Raymond Tallis). Frame of reference in GR: "In the general case of an arbitrary variable gravitational field, the metric of space is not only non-euclidean but also changed with time. This means that the relationships between different geometric distances change over time. As a result, the relative position of the "test particles" introduced into the field in any coordinate system can not remain unchanged." ( Landau-Lifshitz, II). It turns out that since the Big Bang, all the particles in the universe speak, hear and listen to each other in the language of gravity (= irreducible spontaneous measurement). Addition The main misconception in the interpretations of quantum mechanics is that the equally probable nature of phenomena implies their equivalence.* Moreover, not only at 50/50, but also at 99/1. However, equality and equivalence are completely different things, even if they are causally related; for example, all inertial reference systems are equal in SR or QM, but far from equivalent. Obviously, if a dead or a living cat, the spin of entangled photons up or down, pairs of socks or letters marked + or - in different parts of the world are equal, then they are not physically equivalent; and also, branched universes. When an tails falls out after a coin toss, then they talk about the collapse of the wave function, when tails and heads are just equal, but not the same even not only for numismatists.That is, these are physical parameters of different physical phenomena, and their representation by a single wave function according to Born is ridiculous. For example, when energy E=mc^2, then mass m=E/c^2, since they are parameters of the same physical entity, and therefore equivalent. For comparison: in GR, in a gravitational field or in an equally accelerated frame of reference, all events are not only equal, but equivalent, so Einstein criticized QM for not being as radical as RT.** Moreover, RT is even more radical: "Two world points located at zero distance from each other do not necessarily coincide." (Pauli, RT, paragraph 7, Four-dimensional world). That is, even with a repeated loss of heads (or tails), both of these phenomena are not equivalent. Moral: a particle cannot even be in one state at the same time. Finally, we can say that the concept of "frame of reference" was self-sufficient, and the introduction to physics of the concept of "state" was an unsuccessful attempt to describe reality. "A good joke should not be repeated twice."(Einstein).*** --------------------- *) - In logic, this is the basic law: the law of identity. **) - For fans of the multiverse: the equivalent Universe can only be the accelerating Universe itself. ***) - It seems that the uncertainty principle is the result of a misunderstanding of probability/equivalence. In the Heisenberg inequalities, the mathematical apparatus was formed before the interpretation of their physical essence. It is funny that these inequalities indicate that there are no exact values of coordinates and momentum vector in the states of microobjects at the same time; and thus exclude the equivalence of these parameters. If in RT the choice of a reference frame is essentially an experiment (mental or real) that produces a certain splitting of space into spatial and temporal "projections", then in QM there are "two types" of observations: using measuring instruments to measure coordinates and to measure the momentum of microparticles. There is no such separation in the observation process in QG, because instead of "rulers and clocks" in RT or "multi-functional" devices in QM, only a quantum counter (detector) is required, which catches gravity quanta (if the self-action) of physical bodies; without affecting them ("touch" or "illumination"). That is, an observer with a conventional detector is a "quantum reference system".

Bernstein on the nonlocality of one single photon. No probabilities of ensembles needed for quantum physics. "Does a Single Lone Particle Have a Wavefunction ψ? YES. An Experimental Test of Einstein’s “Unfinished Revolution” I propose a simple experiment providing evidence that each individual particle is described by a wavefunction of its own. This is contrary to the interpretation of quantum mechanics (QM) apparently favored by Einstein toward the end of his career, at the time his famous autobiographical notes were written. His so-called statistical interpretation holds that individual particles do not have their own wavefunctions; rather, the quantum wavefunction ψ is supposed to ONLY apply to a very multiple, large ensemble of identically prepared particles. For a single particle it fails Einstein criteria of reality and completeness. The experiment proposed here requires heralded single photon counting. In essence we simply prepare many many down-converted signal particles-each heralded by its own accompanying idler that triggers the whole apparatus; prepare the signal photons in different states, assuring that no wavefunction is represented more than once in the entire set of measurement instances. Then take the full set of individual particle counts and show they agree with the implications of standard QM. The exposition makes several connections to Mike Horne’s interests, collaborations and work. The specific property used herein is polarization. For linear polarizations we recover the cosine-squared Law of Malus by preparing individual photons in all possible orientations, then measuring their passage through a fixed orientation analyzer.

't Hooft had a cute idea, but it doesn't fly. Bob falling into a black hole still falls in and notices nothing too unusual going over the horizon if there is no actual firewall. So the interior is real. Physics aught not get all Hegelian or Logical Positivist or whatever and say what cannot be observed is not real. Susskind and Maldacena resolved the apparent BHIL paradox long ago, but ex-string theorists don't want to listen because they want another source of wacky ideas to get grant funds for exploring... is one possible take.
@1:05:00 't Hooft sketches the same idea, but done more rigorously by Turok and Boyle to answer why the cosmological constant value is so small. Neil Turok and Latham Boyle have found it *_is_* indeed a bit like an inverse of a large number. Performing a Lorentzian path integral and continuing analytically to complex time the entropy of the universe drops out as S=1/Λ (due to gravity the Hamiltonian contribution is zero, or exp(H=0)=1). Since our universe has a lot of matter and radiation is has sizeable entropy, and the most probable universe out of any ensemble is one with P∝exp(-1/Λ) close to 1, so Λ small. This Turok & Boyle result is not a causal account, since it's just statistical mechanics on an imaginary ensemble of possible universes, but a clue about what the source of Λ is. Turok describes it in an analogy as "like a chemical potential for spacetime volume." i.e., energy gained/lost by adding/losing one chemcial species, in the case of gravity that'd be the energy gain/lost on adding/losing an element of spacetime volume. Which is really, whe you think about it, the prosaic normal "explanation" for Λ, which is vacuum energy density. The source of vacuum energy density is the Planck scale topology. That's the answer. We do not know what it is because no one has developed a Planck microscope. ((They aught to find the Planck observatory in it's current graveyard orbit, bring it back down to the lab, hold it dead steady and just look down the other end in reverse.))

The universe decayed out to photons and the size then. When time losses meaning. Double the decayed universes size, and put one next to the other almost touching. Then rewind to current time frame and you get a big distance for a probabilistic universe. The universe is a finite system with solution sets. Quantum tunneling to a lower energy state.

20:34 Root cause analysis. "The geometry of space in general relativity theory turned out to be another field, therefore the geometry of space in GR is almost the same as the gravitational field.” (Smolin). In "GR was QG" there is no problem with empty (~ geometric, mathematical) space-time, since the real variable gravitational field of any physical object is identified with the phase space. When 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**. P.P.S. As a fundamental theory, GR has the ability with just one parameter: r(G)/r=k to predict, explain new physical effects, and amend already known ones. Photon frequency shift in gravitational field Δw/w(0)=k; the angle of deflection of a photon from a rectilinear propagation path =2k, the Newtonian orbit of the planet shifts forward in its plane: during one revolution, a certain point of the orbit is shifted by an angle =3πk, for a circular orbit (eccentricity е=0); in the case of an elliptical orbit - for example, for perihelion displacement, the last expression must be divided by (1-e^2). ------------------- *) - GR/QG predicts a new physical effect: w/w(pl)=k; expression for gravitational radiation from a test body. This is amenable to physical examination in laboratory conditions at present. **) - From this, generally, from Einstein's equations, where the constant c^4/G=F(pl), one can obtain a quantum expression (as vibration field) for the gravitational potential: ф(G)=(-1/2)[Għ/с]^½ (w)=-[h/4πm(pl)]w. Final formula:ф(G)=-[w/w(pl)]c^2/2, where ф(G) - is Newtonian gravitational potential, r(n')=nλ/π=(n+n')2r(pl)l , the corresponding orbital radius, w - the frequency of the quanta of the gravitational field (space-time); - obviously, the quanta of the field are themselves quantized: λ=(1+n'/n)λ(pl) = 2πc/w, where n'/n - system gravity unpacking ratio, n'- the orbit number (n'=0,1,2,3…). Obviously, on the horizon [r=r(rG), n'=0] the "door" is closed, however, the quanta [λ=λ(pl)] can go out singly and form the first and all subsequent half-orbits (n'=1,2, 3 ...) during the time t(0)=r/c=2nт, where т=1/w, т=((1+n'/n)т(pl), spending part of their energy on it each time. And it is this mechanism that provides the step-by-step formation of a variable gravitational field: variably accelerated expansion of spacetime as a phase space: |a|=g=πc^2/L, where L is the length of the phase trajectory (of course, the quanta coming through the "window" are also rhythmically restored). The phase velocity of evolution v'/π= r(pl)w/π; m(0)=(c/2G)rv', where v'=v^2/c. The angular momentum: L(p)=|pr|=n^2ћ [const for all orbits of the system; at n=1: L(p)=ћ] and moment of power: M(F)=dL(p)/dt(0)=nћw/2=-E(G)=E*, where t(0)=r/c, E*- energy of self-action. According to GR / QG, gravitational field [E(G)=-E*] is characterized by a spontaneous flow: J*=(v'/π )(1/4π) g^2/G, where v'/π- phase velocity of field evolution. Entropy (here: a measure of diversity/variety, not ugliness/disorder) of the system: S=πε(pl)r(t)=(n+n')k, where k is the Boltzmann constant. Obviously, on the horizon entropy=min and with fundamental irreversibility, information is preserved (+ evolves, accumulates). Accordingly, m=m(pl)/(1+n'/n), where m=ħw/c^2, is the quantum of the full mass: M=n'm [

In "GR was QG" there is no problem with empty space, since the real variable gravitational field of any physical object is identified with the phase space. Consider a special case: the Universe. Expansion is a special kind of motion, and it seems that the Universe is a non-inertial frame of reference that performs variably accelerated motion along a phase trajectory, and thereby creates a phase space (according to general estimates, this acceleration is: a=πcH)*. Real gravitational fields are variable in space and time, and we can now talk about the fact that it is possible to generate a gravitational field in a non-inertial frame of reference (|a|=g).That is, finally achieve global (instead of local in GR) compliance with the equivalence principle. Then the energy density of the relic radiation, that is, the evolving primary gravitational-inertial field (= space-time): J= g^2/8πG=(ħ/8πc^3)w(relic)^4~1600 quanta/cm^3, which is in order of magnitude consistent with the observational-measured data (about 500 quanta/cm^3). P.S.You can also use the Unruh formula, but with the addition of the coefficient q, which determines the number of phase transitions of the evolving system for the case of variable acceleration: q=√n'=λrelic /√8λpl , , where n'=L/8πr(pl) is the number of semi-orbits; L=c/H, is the length of the phase trajectory. Thus, T*(relic)=[q]ħa/2πkc (=0.4K), which is in order of magnitude consistent with the real: T(relic)/T*(relic)=2,7/0,4=6,7. {However, there is no need to have a factor of 1/2π in the Unruh formula in this case.} ------------------- *) - w(relic)^2=πw(pl)H, |a|=r(pl)w(relic)^2 =g=πcH, intra-metagalactic gravitational potential: |ф0|=(c^2)/2(√8n')=πGmpl/λ(relic). m(pl)w(pl)=8πM(Universe)H; { w(relic)^2=πw(pl)H. From Kepler's third law follows: M/t=v^3/G, where M/t=I(G)=[gram•sec^-1] is the gravitational current. In the case of the Universe, I(G)=MH=c^3/8πG (~ the "dark energy" constant). n' =4,28*10^61; w(pl)=(√8n')w(relic)=8πn'H; where H=c/L. H=1,72*10^-20(sec^-1). By the way, it turns out that the universe is 1.6 trillion years old! The area of the "crystal sphere": S(universe)~n' λ(relic)^2~n'S(relic). r=2.7*10^29cm, L=2πr. The phase velocity of the evolution of the Universe: v'=πcr/L=c/2, where c=√2(v): the "second cosmological velocity" in relation to the proto-universe. {In general, the masses of galaxies should be estimated as follows: M=(c/2G)rv', since the evolution of the system makes an additional contribution to the overall picture, and thereby clarify the problem of "dark matter".} Addition In an arbitrary non-inertial reference frame, the equation of the total mechanical energy of a particle system is: ∆E=A(internal)+A(external)+A*, where A (internal) is the work of internal dissipative forces, А(external) is the work of external non-conservative forces, А* is the work of inertia forces. In order to preserve the mechanical energy of the system in a non-inertial frame of reference, it is necessary that ∆E =0, however, in an arbitrary non-inertial frame of reference, it is impossible to create a condition for fulfilling this requirement; that is, ∆E does not =0 in any way (by the way, in system C, the condition for fulfilling the laws of conservation of momentum and angular momentum does not depend on whether this system is an inertial or non-inertial frame of reference).

@@niblick616 In fact, the observer's self-esteem in QM is underestimated to the level of the infamous ostrich. The observer is always involved in an unavoidable measurement process. It seems that there have never been any problems with QM already within the framework of GR (for example, in the case of the Schrodinger/Carroll cat). A live cat breathes and, accordingly, emits gravitational waves according to the formula GR with intensity: I(G)=(2G/45c^5)(M^2)(l^4)(w^6), where M is the mass of the cat, l is its characteristic size, w is its frequency breathing.The frequency of gravitational radiation should be on the order of w~ 2π/т where т is the characteristic time of accelerated mass movement (pulsation, rotation, collision, non-spherical explosion).It is clear that the dead cat is not breathing and I(G) =0*. In principle, all this lends itself to a certain (improbability) constant measurement without opening the "black box", since gravity is not shielded [w=w(m)]. Moreover, the behavior of the radiation source is also controlled, since it emits only in an excited state. ** Of course, Carroll's sleeping cat breathes, but differently (can be measured) than the waking one.*** Sweet dreams to you QM, on the interpretation of the Born wave function. P.S. Why didn't Einstein use this argument? He wasn't sure about the reality of gravitational waves and assumed only the presence of hidden parameters… --------------------- *) - By the way, a "smile" without a cat can be detected according to Einstein's equations. Raising one of the indices, substituting I=k and summing, we find: R=-(8πG/c^4)T, where T=T(n) is the trace of the energy-momentum tensor (~ "gravitational memory."). **) - If the cat is replaced with a detector, then with each absorption its state will change (which makes measurement possible). It is clear that this will also cause additional radiation of gravitational waves, since the included detector is already a source. ***) - The formula can be given in the following form for a photon: I(G)={[w/w(pl)]^2}ħw^2. Of course, this approach is also applicable to the case of entangled particles. "When physicists offer metaphysical explanations for physical phenomena, I start swearing." (Raymond Tallis). Frame of reference in GR: "In the general case of an arbitrary variable gravitational field, the metric of space is not only non-euclidean but also changed with time. This means that the relationships between different geometric distances change over time. As a result, the relative position of the "test particles" introduced into the field in any coordinate system can not remain unchanged." ( Landau-Lifshitz, II). It turns out that since the Big Bang, all the particles in the universe speak, hear and listen to each other in the language of gravity (= irreducible spontaneous measurement). Addition The main misconception in the interpretations of quantum mechanics is that the equally probable nature of phenomena implies their equivalence.* Moreover, not only at 50/50, but also at 99/1. However, equality and equivalence are completely different things, even if they are causally related; for example, all inertial reference systems are equal in SR or QM, but far from equivalent. Obviously, if a dead or a living cat, the spin of entangled photons up or down, pairs of socks or letters marked + or - in different parts of the world are equal, then they are not physically equivalent; and also, branched universes. When an tails falls out after a coin toss, then they talk about the collapse of the wave function, when tails and heads are just equal, but not the same even not only for numismatists.That is, these are physical parameters of different physical phenomena, and their representation by a single wave function according to Born is ridiculous. For example, when energy E=mc^2, then mass m=E/c^2, since they are parameters of the same physical entity, and therefore equivalent. For comparison: in GR, in a gravitational field or in an equally accelerated frame of reference, all events are not only equal, but equivalent, so Einstein criticized QM for not being as radical as RT.** Moreover, RT is even more radical: "Two world points located at zero distance from each other do not necessarily coincide." (Pauli, RT, paragraph 7, Four-dimensional world). That is, even with a repeated loss of heads (or tails), both of these phenomena are not equivalent. Moral: a particle cannot even be in one state at the same time. Finally, we can say that the concept of "frame of reference" was self-sufficient, and the introduction to physics of the concept of "state" was an unsuccessful attempt to describe reality. "A good joke should not be repeated twice."(Einstein).*** --------------------- *) - In logic, this is the basic law: the law of identity. **) - For fans of the multiverse: the equivalent Universe can only be the accelerating Universe itself. ***) - It seems that the uncertainty principle is the result of a misunderstanding of probability/equivalence. In the Heisenberg inequalities, the mathematical apparatus was formed before the interpretation of their physical essence. It is funny that these inequalities indicate that there are no exact values of coordinates and momentum vector in the states of microobjects at the same time; and thus exclude the equivalence of these parameters. If in RT the choice of a reference frame is essentially an experiment (mental or real) that produces a certain splitting of space into spatial and temporal "projections", then in QM there are "two types" of observations: using measuring instruments to measure coordinates and to measure the momentum of microparticles. There is no such separation in the observation process in QG, because instead of "rulers and clocks" in RT or "multi-functional" devices in QM, only a quantum counter (detector) is required, which catches gravity quanta (if the self-action) of physical bodies; without affecting them ("touch" or "illumination"). That is, an observer with a conventional detector is a "quantum reference system".

Gerard 't Hooft is one of the rare physicists who admits QM isn't a theory but a set of rules, so we don't even know the boundary conditions of a quantum system employing the Schrodinger's equation to study unitary evolution. Tis makes it easy for Anglo Saxons to bag most of the Nobel Prizes, giving a few to the Jews.

@@frun No it doesn't - quantum physics does not just deal with probability. That was Einstein's projection as an error. See my quantum physics professor Herbert J. Bernstein on the nonlocality of one single photon. No probabilities of ensembles needed for quantum physics. "Does a Single Lone Particle Have a Wavefunction ψ? YES. An Experimental Test of Einstein’s “Unfinished Revolution” I propose a simple experiment providing evidence that each individual particle is described by a wavefunction of its own. This is contrary to the interpretation of quantum mechanics (QM) apparently favored by Einstein toward the end of his career, at the time his famous autobiographical notes were written. His so-called statistical interpretation holds that individual particles do not have their own wavefunctions; rather, the quantum wavefunction ψ is supposed to ONLY apply to a very multiple, large ensemble of identically prepared particles. For a single particle it fails Einstein criteria of reality and completeness. The experiment proposed here requires heralded single photon counting. In essence we simply prepare many many down-converted signal particles-each heralded by its own accompanying idler that triggers the whole apparatus; prepare the signal photons in different states, assuring that no wavefunction is represented more than once in the entire set of measurement instances. Then take the full set of individual particle counts and show they agree with the implications of standard QM. The exposition makes several connections to Mike Horne’s interests, collaborations and work. The specific property used herein is polarization. For linear polarizations we recover the cosine-squared Law of Malus by preparing individual photons in all possible orientations, then measuring their passage through a fixed orientation analyzer.

As soon as you start needing to add correction factors into equations to make them fit with observation, you can be sure they are incorrect in some aspect. That is why this dark energy hypothesis is clearly (to me) a nonsense, if you can’t explain an observation with existing theories then adding an unknown to explain it is daft, clearly the existing theories must be erroneous.
