The Milky Way is a spiral galaxy made up of a supermassive black hole center, a central bar or bulge, and an outer disk. The Figure shows the bar and disk both simplified as rotating body pairs that radiate both scalar and vector gravity waves. The scalar gravity waves radiate outward from both bar and disk while the vector gravity waves couple disk to bar stars. The radiant vector gravity waves of the inner bar accelerate the outer disk stars and the radiant vector gravity wave of the disk decelerates the inner bar star rotations. The coupling of vector gravity then transfers angular momentum from slowing bar star rotations by accelerating disk star rotations.

# Matter Time, Aethertime

Accelerating light leads to the simple axioms of discrete aether and quantum action. Matter action augments the more limited reality of continuous space, motion, and atomic time. With the quantum action of the Schrödinger equation and a single fundamental aether particle, two constants predict all action and all other physical constants. In the discovery of truth, there are only atoms and quantum action.

### Discrete Aether Quantum Gravity Radiation

*(m/a)*, as well as, to a lesser extent, the eccentricity of its orbit,

^{5}*ϵ*. Spherical orbits have ϵ = 0 and so a rotating binary of equal masses has a simple expression where gravity radiation goes as the fifth power of its mass gradient.

For two orbiting bodies of very different masses like the
Sun and Mercury or the stars of a galaxy, the expression becomes

For two radiating and orbiting bodies like a binary star of
equal masses, there is an additional vector gravity term that is the ratio of
radiation and relative velocity.

Mercury has the largest eccentricity of any planet in its orbit with the Sun and the perihelion advance of Mercury has long validated Einstein’s relativity. Mercury’s perihelion advance is a result of gravity quadrupole radiation as Table 1 shows that decays its orbit and increases its velocity.

The emission of 5.2e-15 kg/s gravity quadrupole results in the Mercury orbit decay that is the perihelion advance. Since the same quadrupole emission occurs for discrete aether, the Mercury perihelion advance also validates discrete aether.

The Milky Way galaxy has a dipole luminosity of 4.3e19 kg/s, which is 1e10 x the Sun luminosity and due to its 2.5e11 stars. The gravity quadrupole Milky Way luminosity is much smaller at 1.3e15 kg/s than the dipole luminosity, but the much larger dipole luminosity also results in a quadrupole luminosity of 1.4e14 kg/s. This 13% increase in gravity wave emission decays all star orbits and therefore increases their orbital velocities just like the perihelion advance of Mercury.

The merger of two 6.0e31kg blackholes over 0.25 s results in quadrupole emissions of 3.0e29 kg/s at 1% of the total mass loss of the event. The onset of the inspiral occurs at r = 7.6e12 m, which is the point when the quadrupole radiation is just 1% of the total. There is also dipole emission from gravitation, but that emission is spread all over the universe.

### Quantum Gravity of Discrete Aether

Quantum gravity is just a residual force of the quantum causal set, which exists outside of space and time. Instead of matter and action in space and time, space and time emerge from matter action of a causal set. Space as distance and time as relative quantum phases of the quantum photon exchange bonds emerge from neutral bodies like hydrogen atoms. Beyond a certain distance, about 70 nm for two hydrogens, quantum gravity is greater than the dispersion of quantum photon exchange. Quantum gravity between two hydrogen atoms is just the dispersion of quantum photon exchange of each atom with the rest of the universe.

Gravity relativity emerges from the fundamental equivalence of mass and energy for particles that exist in relativistic spacetime. To first order, the Lorentz invariance of the speed of light to velocity of a particle distorts space and time by the classic sqrt(1/(1 - v^2/c^2)). There are higher order terms that converge to the Einstein tensor as proportional to the energy-momentum tensor,

All of the complexity of general relativity reduces to this tensor equation and yet there is no accepted quantum gravity in spacetime. This is because each particle of matter introduces a singularity at r = 0 in spacetime that precludes a quantum electrodynamics exchange particle for gravity.

One consequence of GR is the black hole singularity that are widely accepted in general relativity but have no quantum meaning in QED. A black hole has mass and spin just like any other particle in the quantum causal set universe and black holes bond to the universe with photon exchange just like all matter particles. Thus, black holes are just another matter particle in a quantum causal set, which is about each matter body bonding to the rest of the universe with quantum photon exchange.

### Large Scale Structures in the Cosmic Microwave Background

The cosmic microwave background (CMB) multipole analysis shows an angular scale consistent with a combination of 4.9% ordinary matter, 27% dark matter, and 68% dark energy expanding at 68 km/s.

However, this cosmology does not include quantum gravity at all and so there is no way to measure the absolute expansion rate of the universe. Although the small scale CMB structures are consistent with the cosmology without quantum gravity, there is an inconsistency in the large scale CMB structures of the universe as the figure shows.

A cosmology that has quantum gravity shows a universe of ordinary matter that is only 1.1e-7 kg/kgAether, 8.7e-69 kg/aether, and 8.4e-61 kg.kgAether action contracting at the rate of 77 km/s. The matter-action quantum cosmology shows both a static gravity as well as a radiant vector gravity. The large scale CMB structures are consistent with radiant vector gravity.

### Scalar Static Matter and Vector Radiant Matter Gravity

Since matter-action gravitons are biphotons, which are entangled photons, there is not only scalar gravity due to static matter graviton shadows, but also a radiant vector gravity due to radiant matter. In other words, the radiation of stars entangles their motions with other stars and this entanglement results in radiant vector gravity.

Here is a diagram that shows scalar gravity shadows that results from the matter body bonds to the universe along with the radiant vector gravity that transfers momentum from inner to outer stars. Radiant vector gravity transfers momentum from stars inside the CofM to stars outside the CofM. This radiant momentum transfer is what keeps spiral galaxies rotating at constant velocity instead of at their Keplerian velocities.

The plot below shows the velocity profile of the Milky Way along with the observed Sun as opposed to the Keplerian Sun. The actual Sun velocity is about 29% greater than the Keplerian Sun velocity reported by Sofue et al, 251 vs. 194 km/s. The Keplerian gravity force at the Sun at 8.0 kpc is 8.4e14 kg m/s^2, which is consistent with a Sun velocity of 194 km/s as opposed to the actual Earth velocity of 251 km/s.*2.1e10 Lsun / Nstars*, this result further suggests that the number of MW stars is 91 billion as Nstars = 2.1e10 / 0.23, which assumes that MW stars at r = 8.0 kpc are representative of the whole MW. This MW 91 billion star estimate is at the lower end of the typical 100-400 billion star number estimate often cited.

### Graviton Noise of Quantum Gravity

We live in an ocean of graviton noise and so it is graviton noise that is what makes things happen in our quantum reality. Entangled photons, biphotons, make up gravitons and are what bind each body to the universe of black holes. Black holes are the penultimate heat sink for all of our reality and what we see as gravity attraction is actually just the collapse of the universe matter.

The destiny of all black holes is then a single black hole that is the destiny of this cycle of the universe. In other words, bodies do not really bond to each other with gravity. Instead each body bonds to the universe of black holes and we see gravity attraction as the universe collapse.

The graviton noise of the universe is what makes all wavefunctions collapse and so is what makes reality real...

### Discrete Aether Time Pulse

The discrete aether pulsed universe has a nice symmetry between its time pulse and the hydrogen time pulse defined by the Bohr time. The universe pulse is a 13.9 Byr sinc function of cosmic time with a Fourier transform that is dominated by the aether particle spectrum. The hydrogen pulse is a sinc function of cosmic time with a Fourier transform mass spectrum of the total universe mass that is 90% hydrogen mass.

### Discrete Aether Predictions

Star decay produces star matter waves that couple the motions of stars with a vector gravitization much like charge motions are coupled with vector magnetization. The two stars, Procyon and Cygni-61, are both 11.6 lyrs away from our sun, which couples their motions and affects the Sun’s convection with an 11.6 year period.

Sunspot activity went into a hiatus around 1680 as the plot shows, which is consistent with the Cygni-61A/Cygni-61B periapsis or closest approach at that time. Cygni-61 is a double star and so its double star orbit plays a role in the sunspot activity of our Sun. Thus, the 678 yr orbit of the Cygni-61A/B double star will reach apeosis again in the year 2358. The Procyon A/B double star has a 40.8 yr orbit and shows up as a 40.8 year shift in sunspot peak and intensity.

9) Since matter decay is equivalent to a force, discrete aether predicts that a matter decay of 83 MW/kg is equivalent to the 1.0 G force of earth’s gravity. The sun radiance is just 1.9e-4 W/kg and it would take a 1 kg U reactor pile 12,000 K to achieve 83 MW/kg. This is equivalent to a 1 kg U shell 22 m diameter radiating at 1,000 K, which is below the U melting point.

### Single Photon Resonance as Fundamental Action

We only really see things that change and then we deduce how things are from how they change. It then seems reasonable that the universe is made up of not only things that change, but also things that are. Single photon resonances are the things that are and make up all change and single photon resonances occur between emitter precursors and absorber outcomes. Single photon spectra make up the fundamentally discrete nature of the universe with emitter and absorber chromophores.

A single photon resonance between emitter and absorber chromophores exists as a cosmic time packet that grows and then decays, which defines its time packet. Atomic time and space emerge from the quantum oscillations of that photon burst from the speed of light and its wavelength. The growth and decay of the photon packet define its location and direction and result in the Lorentzian spectrum that this example shows. The arrow of time emerges as the direction from primordial emitters to black hole absorber destiny outcomes.

The universe itself is then a spectrum of aether whose exponential decay defines not only a cosmic time, but also defines charge, gravity, and all forces along with the quantum oscillations from which atomic time and space emerge.

### Gravity Lens and Blueshift from Photon Convergence

### Gravity Binds Black Holes to the Universe

Gravity is an apparently attractive force that is actually a result of the bonding of each body to a shrinking universe full of black holes. Gravity attraction between two bodies along their line of action is a result of the universe bond gravity shadows of each body on the other. In the idealized gravity between two hydrogen atoms, each atom bonds to the shrinking universe by the emission of its Rydberg photon into the resonance brane between each hydrogen and a black hole. It is then the pulse decay of the shrinking universe that results in the action-centered gravity that accretes all matter, light, and neutrinos into black holes and eventually into the final single black-hole destiny of the universe.

The figure shows that the gravity bond between two hydrogens idealized as two photon exchange bonds between each hydrogen and a black hole. Of course, once the hydrogen atoms get closer than about 70 nm, single photon exchange bonding between hydrogens overwhelms this gravity attraction. It is only for substantial bodies that gravity then overwhelms photon exchange bonding.

The gravity bond is then not due to exchange of a single particle like a biphoton, rather gravity is due to two photon exchanges as a quantum biphoton and so there is really no knew science needed for the quantum gravity. Instead of very complex new graviton math that resists renormalization, matter-action biphoton gravity uses the same photon exchange of quantum electrodynamics. Note that matter-action gravity is now action centered and not body centered, which means that gravity does not have the pesky singularity that precludes gravity renormalization under QED. Therefore, biphoton gravity uses the same renormalization of QED and quantum charge.

Black holes still represent the destinies of all matter, light, and neutrinos, but are simply a different kind of quantum matter action without space or time. Space and time do not exist for black holes, but quantum phase, matter, action, and cosmic time all still exist for black holes. Matter, light, and neutrinos are all matter-action precursors for black-hole outcomes and black holes are the precursors of ever larger black holes. Eventually, a single large black hole is the precursor of the antiverse expansion of aether and the antiverse is then the precursor to yet another universe decay cycle.

An enduring mystery in Science has been the seeming 1/r2 similarity between gravity relativity and quantum charge scaling and yet the very large 1e41 differences in their strengths. The difference in strengths is a result of the difference between the size of an atom and the size of the universe. So bonding black holes to the cosmic microwave background with biphotons is a quantum gravity that scales correctly and finally completes the quantum nature of reality.

### Qubit Atoms, Molecules, and Quantum Computing

In fact, a real qubit decays and that decay limits the qubits. A real qubit is never perfectly isolated from thermal and phase noise environment and also has a limited phase coherence lifetime on the order of 10 microseconds. There are therefore many hurdles to overcome before any practical qubits of quantum computing become a reality. Much like the early days of the practical 0 and 1 bits of semiconductor logic, Science has a long ways to go in order to realize a useful practical qubit that includes not only 0 and 1, but also quantum phase, theta.

The superconducting Josephson junction is a fundamental quantum oscillator that involves electron (Cooper) pairs tunneling through an insulator layer between two superconductors at very low temperature. Instead of the electrons and holes that determine semiconductor 0 and 1 bits, a Cooper pair is inherently a qubit. For a current of 40 nA, about 1e9 electron pairs result and from a 13 microV, a frequency of 6.6 GHz at 0.015 K. The Cooper pair current results from the specific geometry and materials of the junction as well as the applied voltage but the frequency is always just proportional to the applied voltage. In fact, this junction is a quantum oscillator at that frequency where each excited state includes one additional Cooper pair of electrons at a slightly lower frequency due to anharmonicity.

The basic qubit of a quantum computer incorporates not only the 0 and 1 of a classical bit, but also a quantum oscillation between 0 and 1 of the Cooper pair across a junction. A very common qubit is a particular Josephson junction called a transmon that incorporates a shunt capacitor to make the quantum oscillator more stable. The transmon that oscillates at around 6.6 GHz and so its qubits undergo this same quantum oscillation.

Another common qubit is the squid, which involves a loop with two Josephson junction. In any case, a qubit is the excitation of just one Cooper pair, 0 -> 1, across a junction at about 200 MHz lower frequency due to anharmonicity. The quantum anharmonicity also means that the 1 -> 2 transition is 200 MHz less that then 0 -> 1 transition. In fact, useable qubits need to have such isolated transitions and so the anharmonicity is what makes the transmon and the squid useful qubits as the figure shows.

However, there is an additional splitting of each level due to the phase or direction of the electron pair across the junction and that splitting reflects the spin or rotation of the qubit as the figure below shows. Much like electron spin emerges from the complementary rotations of electron charge loop oscillation, the complementary rotations of superconducting loop oscillations in the transmon and squid are then a kind of qubit spin.

*n*. Gate bias increases charge dispersion up to 60 MHz as the figure shows.

_{g}*T*, is therefore usually about 10 microsec, which is long enough for reading and still short enough for resetting, which all involve 10 nsec switches. The dephasing time,

_{1}*T*, is due to the entanglement among other qubit states that is necessary for effective computation. This dephasing time is important for quantum entanglement outcomes and is therefore limited by

_{2}*T*. However, it is then difficult to differentiate dephasing from pure decay.

### Spin as a Loop or 0-Brane String

Unlike a photon resonance between particles, which is a one dimensional D-brane string with Dirichlet boundary conditions, a particle spin has cyclic boundary conditions and so is a 0-brane loop string and not a D-brane string. Since particle spin dimensions do not map directly into 3D space and time, for quantum energy calculations, typically two dimensional Dirac spinors represent spin dimensions separately from 3D space and time. Given that spin resonance energies tend to be much smaller than other quantum orbit resonances, this spin-orbit separation of variables works very well for many energy calculations that include average spin.

When instantaneous quantum phase matching is important, though, the 0-brane loop string is then useful since it shows both mass and charge oscillation as a 0-brane loops as well as the three D-brane magnetic fibers that take a 4𝜋 rotation to return spin magnetic identity. The figure below shows how the spin D-brane fibers do not cross each other and therefore maintain their orthogonality.

Since quantum phase matching is still an issue with the resonance of spin-orbit coupling, the 0-brane spin phase is useful for matching the D-brane orbital phase. In the first excited state of hydrogen, the coupling of the electron spin magnetism to the electron orbit magnetism results in the fine structure of the hydrogen spectrum. The figure shows three of the many different short-lived electron P-type orbital resonances. There is only a well-defined average electron energy and radius for the hydrogen fine structure.

### Photon Geodesics as D-Brane Strings

Photon resonance geodesics are the basic quantum exchange bonds responsible for both quantum charge and quantum gravity. While quantum charge photon exchange is a resonance along the geodesic between two bodies, this photon exchange also bonds all bodies to the universe with quantum photon exchange and so is quantum gravity. The attraction of quantum gravity is then the residual attraction due to geodesic shadows of the universe that the two bodies cast on each other along their line of action.

Gravity waves in space and time represent matter action radiation that can then eventually lead to matter action acceleration as well for very massive objects like black holes and neutron stars. Black hole mergers result in large amounts of matter action acceleration and radiation but very little or no dipole radiation because black holes are charge neutral.

Classical relativistic gravity is a scalar force, since it does not depend on direction and so classical gravity attracts bodies together just like charge is also a scalar force that attracts opposite charges together. Nevertheless, both gravity and charge do act along their lines of action between bodies. In contrast to classical gravity motion, charge *motion *further results in vector force call magnetization that then couples charges together with a force perpendicular to each of their lines of action.

Since matter-action gravity is really just a version of quantum photon exchange, there is also a quantum gravity vector force also exists. However, gravity motion always couples complementary photon pairs as a quadrupole and so vector gravity couples the motions of stars and would also be perpendicular to their lines of action. In fact, vector gravitization is then the precursor to the dark matter force that couples galaxy stars into a constant rotation.

String theory is a very flexible theory of everything and uses branes as either loop branes or D branes with any number of hidden new dimensions. The "D" stands for Dirichlet boundary conditions as two brane endpoints and not a string loop. String theory can then explain any measurement by adding as many new dimensions or parameters as needed to fit measurements of physical reality.

However, a quantum D-brane string in just one dimension has all of the properties of an electron charge and matter oscillation and so a trivial D-brane with just one dimension is consistent with physical reality without any extra added dimensions. A D-brane electron would actually span the universe and not really be microscopic or hidden either. In fact, a photon and any quantum particle is then also equivalent to a trivial D-brane.

Therefore, such trivial D-branes already make up the causal set universe. Such quantum D-branes have the quantum property of oscillation along their lengths and so a D-brane also represents a photon resonance geodesic between two emitters, say Alice and Bob. Thus, D-branes without any new hidden microscopic dimensions form the basis of a quantum causal set universe and so there is no need for any new but hidden microscopic dimensions.

Alice and Bob in a resonant photon exchange represent a D-brane, but now as the resonance or connection between two Dirichlet endpoints or vertices. Of course, such D-branes can and do span the universe as the CMB, but such D branes actually represent the bonds of quantum photon charge exchange as well. Since all bodies have a very large number of D-branes that bond them to the universe, attractive gravity between two bodies is actually a result of the universe collapse and so the universe is not expanding.

After CMB excitation, the Alice-Bob D-brane resonance does not reveal any cause or effect and so this universe is not yet real. A black hole absorption occurs at Bob is what reveals Alice as the emitter precursor and Bob as the outcome absorber. The black hole absorption sets the arrow of time and is what makes the universe real.

There are many things about the universe that D-branes reveal. For example, bodies shadow each other’s D-brane bonds with the universe along their lines of action and so gravity is simply a result of these shadows of the universe collapse as the diagram below shows. String theory is just as fun as causal set theory... however, loop quantum foams do not have branes and so are no as much fun... Tejinder Singh, though, has a great TOE that does use path integrals and cosmic time along with octonions... but we need to get spin involved somehow as well...

### Single Photon Double Slit Diffraction

There are many different ways to show that a single photon is actually a superposition of both slits in the double slit experiment and this was a particular good one.

Double slit single photon with microscope

The author has done a really good job with his double-slit microscope with a HeNe laser and a CCD to image the diffraction pattern. He only missed a few details in his experiment, which also showed excellent single-slit as well as double slit-diffraction. It was very clever to simply lower the beam intensity in order to show single photon behavior and so this is an experiment that I could do with my microscope and laser as well.

In his explanation, he described a dipole source as spherical source in all directions, but of course a dipole is a planar and not a spherical source. This does not really change any of his conclusions.

He did not talk about the fact that the emitter and detector were in resonance for the lifetime of the emitter, which was about 1 ns or so for a 632.8 nm HeNe at 0.3 mW with a 1 GHz bandwidth. Each single photon has a 1/e coherence length of 300 mm and so the emitter and detector are close enough for quantum phase correlation. His diagrams incorrectly show very short photons while the actual HeNe photon is in fact much longer, especially as an amplitude, which is sqrt of the intensity length.

The single photon width corresponds to the 1.5 mm HeNe beam width and so a single photon always goes through both slits as long as the beam diameter covers both slits. Therefore, this is not a mystery at all and the true mystery is why does anything ever behave like a classical particle at all. The simple answer is that it is the decay of the quantum photon resonance that makes a photon classical. That is, it is the decay of this source-detector quantum resonance at the detector that makes the quantum photon a classical particle.

Finally, he mentions that the single slit diffraction also means that the single photon interferes with itself and this is true. He suggests that the single slit acts like a resonant chamber and this is exactly correct. In fact, there is a short and quite measurable delay in the photon transit through a slit because a photon lives longer in the slit.

All in all, a very nice demo!

### Quantum Gravity Black Holes

Quantum matter action results in a causal set universe where space and time emerge from a sprinkle of random quantum photon resonant paths. The quantum gravity of matter action is Lorentz invariant and therefore completely consistent with the measurements of Science. However, matter-action interpretations of those measurements are quite different from spacetime interpretations.

This is especially true for the gravity black hole singularity of Science since gravity black hole singularities do not have a basis in quantum gravity until now. This is largely due to the nature of the black-hole singularity and the sprinkled photon resonances from which spacetime emerges do not have any singularities.

Gravity relativity is a body centered force in spacetime that curves or warps spacetime around that body. Thus, bodies follow the straight-line geodesics in warped spacetime and so there is no spacetime gravity force, just gravity warping of spacetime.

In matter action, quantum gravity is a result of the random photon geodesic resonances that complement the quantum geodesic resonances that bind charge matter. The matter-action causal set shows not only the photon geodesic resonances that bind quantum charge, matter action also shows those photon geodesic resonances that bind each body to the universe. Instead of gravity relativity warping spacetime, quantum gravity is the result of bodies shadowing each other's universe geodesic bonds. Thus quantum gravity force occurs along body centerlines and so quantum gravity is then a center-of-mass force and not actually a body-centered force.

A quantum black hole is then consistent with all measurements of black holes, but a quantum black hole is much more interesting than the singularity of a spacetime black hole. Photon geodesic resonances deflect around black holes because of the gravitational red shift and constant speed of light. However, there are still quantum resonances that occur between a black hole and an emitter and absorber of light.

A quantum black hole still has the very slow decay of cosmic time as a spiral decay, which has no meaning in spacetime relativity. The spiral decay in cosmic time of a quantum black hole is very reminiscent of the interpretation of a black hole as an eternal collapsing object without an event horizon. Thus, quantum black holes are the natural outcome of a all collapsing matter in the matter-action universe.
