It is nice to hear a reasonable explanation, that does not sound like magical thinking. Also one that is actually focused on testiblity.

Between the two: My vote is that the "Big Bounce" is best ... But inversion physics - and teaching more about tensor analysis would be useful for physics majors...(Again: Edward Teller's videos about his attending Einstein lectures: Summary, Einstein's Special Relativity is an A+... while General Relativity??!(huh?!)? - Teller's videos about attending a lecture by Einstein in the 20s should be mandatory for ALL physics majors. )

The biggest (only?) hurdle is assuming gravity to be an attractive force. It can be seen rather as the dissipative force of the elastic solid of spacetime or dark energy as it resists the compressive forces due to quantization after a large perturbation (see Padmanabhan (2004) for an example of ‘elastic solid’ spacetime being equivalent to Einstein’s general relativity calculations). Scientists are already exploring the ‘repulsive’ forces they are attributing to dark energy (elastic solid spacetime in this view). Why not extend that ‘repulsiveness’ to dissipative gravity rather than assuming opposing forces? Gravity only appears to be attractive due to the conservation of energy as spacetime/dark energy is pulling everything apart while the strong force and aspects of electromagnetism keeps quantized matter in balanced, ‘bounded’ systems. This dissipative gravity and its amplified cousin, the weak force, along with the symmetric dissipation of the Higgs field and the dark matter field are the physical sources of entropy. So along with the assumption of special relativity, the energy of the strong force with relatively minor contributive forces of electromagnetism is symmetric with the dissipative forces of electromagnetism, gravity, the weak force, the Higgs field, the dark matter field, and the cosmological constant. With this view there is no longer a need to assume singularities, extra dimensions, or a number of other mathematical artifacts that arise due to the current theories, gravity is easily reconciled with the other forces, and everything at every scale is a dissipative system, including people-a complex system of embedded dissipative systems ensembles. Elegant. Beautiful.

Pardon a layman, but hasn't miniboone at fermilab already found pretty strong evidence for sterile / right handed neutrinos?

Very heartening that the slow contractions universal smoother comes out of general relativity.

Do recent discoveries of very large scale voids upset Neil Turok’s requirement of a flat, isotropic universe? I seem to recall Sabine Hossenfelder reporting on these voids in one of her recent videos (2023/2024).

Worthwhile video, and you have a new subscriber. However, I do wish you had asked about pushback on his theory. In this video, Steinhardt makes it sound like cosmologists are pretty evenly split between his view and inflation, but in reality, most cosmologists are still invested in inflation theory, and "slow inflation" is a radical new idea with very few adherents. I personally find it exciting, but people far smarter than me don't give it the time of day. So what do Alan Guth and other "hardcore inflationists" think about Steinhardt's ideas? What is their response to his criticisms of inflation? This is what I would like to know now. 🤷

I like where Niel is going with his work. Nature seems to prefer simplicity and all things being equal, nature will always take that route.

I really miss my days at University of Chicago Physics department with the Gravity group.

Great talk. May I suggest better microphones? The sound is subpar.

Thanks, I'm really excited about this work by Neil Turok and look forward to seeing more details whenever they appear.

Thank you for this interview. There's an unforgivable under representation of Neil Turok's brilliance on RUclips.

Neutron decay cosmology A homeostatic universe maintained by the reciprocal processes of electron capture at event horizons and free neutron decay in deep voids. Neutron in at event horizon Neutron takes EinsteinRosen bridge from highest energy pressure conditions to lowest energy density point of space Neutron out in deep void where the quantum basement is lowest and easiest to penetrate. Neutron decays, into amorphous monatomic hydrogen, proton electron soup, DARK MATTER The decay from neutron 0.6fm³ to 1m³ of hydrogen gas is a volume increase of 10⁴⁵. Expansion. DARK ENERGY In time the gas stabilizes into first monatomic and then molecular hydrogen as it slowly falls down the gravity hill. Until in the far distant future it is again about to contact an event horizon. The Hubble red shift is a geometric artifact. The curvature of spacetime caused by the mass between observer and observed.

I’m a lay person with a life long interest in cosmology so forgive me if I sound silly but it sounds like the description for a Groundhog Day universe. How can all the expansions after the “bounce” create something different if the ingredients don’t change because the goal is to always maintain universal smoothness.

Finally! A very compelling and “simple” idea to the nature of the universe. No strings or 14 dimensions which are untestable. I can’t wait for the galaxy survey results. What a brilliant mind.

Neil's ideas are so interesting.

27:00. : "It can be convincingly proved that reality cannot be represented by a continuous field at all. It seems to follow from quantum phenomena that a finite system with finite energy can be completely described by a finite set of numbers - quantum numbers... A purely algebraic theory is required to describe reality." (Einstein, January, 1955). Maybe GR was QG… “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). However apparently, 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 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 through the "keyhole" 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/G)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 [<m(0)]. The parameter mλ [=m(pl)λ(pl)=m(w)λ(w)=m(e)λ(e) ] covers the entire spectrum of particles. Thus, m(0)=(n+n')m, where 2∆m=nm - mass defect; M/2∆m=n'/n: on the horizon m(0)=2∆m, M=0. That is: ф(G)=-Gm(0)/r=-[G/2r(pl)]m. Can be tested experimentally in the laboratory at the moment. {The experimenter needs only two parameters; the mass (gram) of the body under study m(0) and the distance from its center (centimeter) r: so the energy of the quanta of the field ε(eV) ~1.83(m/r); the radiation flux J*[erg/cm^2•sec]~7.57•10^-27(m^3/r^5). For example: A lead ball suspended on a strong chain from the ceiling of the laboratory can serve as a test body; at radius r=27,6 cm, ball mass is m=1т. The energy of quanta/photons of the field (photons are characterized by different parity and helicity, and it is not quite accurate to say that a photon has an integer spin equal to one) at a distance r from the center of the test body to the detector (practically on the surface of the ball) =66,3 keV. The flow: J*=4,5•10^-9 quanta/сm^2sec; this is a measurable flux for modern world-class gamma detectors. (On the Earth's surface, the frequency of the quanta of the Earth's gravitational field: w=2.57*10^34 Hz (~2.7 J); and even with such a huge flow of them: J(G)=0.3 MW/cm^2, - they are elusive for modern detectors.)}.

17:00. 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).

There is no hole where a black hole exists.

Big Bang is childish idea, it is not science.

Penrose's gravitational singularity is a pure failure.

The universe is non-created, the Big Bang model is religious dogma, and the universe is eternal, with no beginning. We cannot go back in time because time has no physical existence. The universe is NOW, it exists in time-invariant space.

Hi there did you know about neutrino 4-experiment, conducted by Anatolii Serebrov...

An intriguing alternative to the conventional concept of dark matter is the Janus model, which introduces the idea of negative mass matter. According to this theory, there would be particles of negative mass antimatter that would repel the ordinary matter that makes up our galaxies. These particles would be invisible to our instruments because they would emit negative energy photons, thus eluding conventional detection. This concept is supported by a large number of astronomical observations currently attributed to dark matter, without resorting to the specific adjustments of the standard model, which is increasingly inconsistent with recent observations. It even provides a nature to this antimatter composed of anti-electron, anti-proton, anti-neutron, anti-hydrogen, and anti-helium with negative mass. ruclips.net/video/OZTdBUY28Qk/видео.htmlsi=fubU0Zs978y75eVj

Black holes are based on a mathematical misconception. General Relativity predicts dilation, not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is one aspect of dilation. Wherever there is an astronomical quantity of mass, dilation will occur because high mass means high momentum. Dilation is the original and correct explanation for why we cannot see light from the galactic center. It can be shown mathematically that the mass at the center of our own galaxy must be dilated. In other words that mass is all around us. Sound familiar? This is the explanation for dark matter. The "missing mass" is dilated mass. Dilation does not occur in galaxies with very, very low mass because they do not have enough mass in their centers to achieve relativistic velocities. It has recently been confirmed in 5 very, very low mass galaxies to show no signs of dark matter. For the same reason binary stars will always have predictable rotation rates..

There. Is no expansion of the universe …
