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...


Social bonds are also D-brane resonances that couple expressions and between people that result in attraction as shown below. Once again, CMB precursors drive all D-brane excitations and black hole outcomes drive all D-brane decays, providing the arrow of time. It is the arrow of time that makes reality real...

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.


The quantum black hole is really not black at all and, just like any quantum body, not only absorbs light as heat, but also reflects and transmits light to emitters as well as other black holes. The Ricci tensor of relativity shows the effect of matter on spacetime, but the random red shifts of photon geodesic resonances sprinkled into spacetime correspondingly reveal the presence of matter. Photon resonance geodesics are simply causal links between bodies that are the underlying structure of matter action from which space and time emerge as gravity relativity.


The quantum causal set of a black hole incorporates the same causal set emitter pair geodesics as does all of reality. Of course, the emitter superposition only decays with quantum black hole absorption and it is only then that there is an arrow of time.


Quantum black holes, just like all matter, have both reversible quantum resonances as well as irreversible quantum decays. While reversible quantum resonances represent superpositions that are the basis of reversible atomic events without time's arrow, irreversible quantum decay is the basis for the very slow cosmic time arrow for universe decay. Black holes absorption are a universal heat sink that ultimately determines the irreversible atomic time arrow for each photon geodesic.
