Latest results from quantum electrogravity (QEG), 2025-03-12.

Three new kinds of gravitons explain inertial reference frames, classical quantum mechanics, and dark matter.

 
Parity violation is evidence that our universe is inside an extremal Kerr black hole (plus QEG), 2024-03-24.

Parity violation occurs because our universe is inside an extremal Kerr black hole.

Our universe is part of the holoverse, which consists of black holes nested within black holes, ad infinitum.

The spot on my forehead is a natural bindi, signifying an open third eye, which means that I have infinite wisdom. The scar on my upper lip is from face-planting on a rock while out hiking with my wife, which means that I am a klutz.

 

📌Oct 17, 2026: new in Papers: several people have requested copies of my 1980s papers on AI and backpropagation (which I called Learning-Logic), so I have added links or pdf files for the papers I could find online. Highlights:

Backpropagation in 1985.

A backpropagation network. It includes a simple example of a recurrent feedback connection on the right-hand cell in the middle row. The 1982 Stanford patent procedure for my work became moot when I learned of Paul Werbos's earlier work (see my 1987 paper). Figure from Learning-Logic: Casting the Cortex of the Human Brain in Silicon, Feb, 1985.

Direct propagation in 1987.

A direct propagation network. The signals are not constrained to going layer-by-layer, but instead can propagate directly through multiple layers. This is similar to how our brains are structured. Direct propagation leads to a better approximation to optimal 2nd order backpropagation; the improved communication between different layers leads to better performance, kind of like a corporation. Figure from Optimal Algorithms for Adaptive Networks: Second Order Back Propagation, Second Order Direct Propagation, and Second Order Hebbian Learning, Jun, 1987.

Announcing the Creation Toolkit, version 1.0

The April 2027 APS Global Physics Summit will mark the official launch of the Creation Toolkit, version 1.0. The long term goal of the Creation Toolkit is to recursively recreate our universe on a computer, or network of computers, by exactly simulating the laws of physics in software. Exactly simulating the laws of physics is now possible due to advances in absolute gravity (AG), absolute quantum gravity (AQG), and quantum electrogravity (QEG). Creation Toolkit 1.0 focuses on vacuum physics. The two operating modes are an approximate classic mode and an exact quantum mode. The approximate classic mode allows for comparisons with other traditional approximate gravity simulation algorithms, such as ADM 3+1. Using AG, the Creation Toolkit is fast enough to simulate the interiors of black holes, and to simulate collisions of several black holes with arbitrary spins, masses, and trajectories. On a laptop computer with 16GB of RAM. In exact quantum mode, Creation Toolkit 1.0 uses AQG to exactly recreate the physics of our universe. Space and time are quantized, and gravity is transmitted by the three kinds of AQG gravitons. This talk will be a brief introduction to using the Creation Toolkit, with colorful pictures and movies. Detailed discussions will be left to the associated poster session.

Absolute quantum gravity (AQG) (talk)

I have quantized general relativity. The result is a set of three new kinds of gravitons: a scalar g graviton, a vector w graviton, and a matrix S graviton. The S graviton is the "fast" graviton; its field equation goes as d2/dt2, like the wave equation or the Klein-Gordon equation. S gravitons are responsible for the long range gravity waves observed by LVK. In vacuo, S gravitons move at the same speed as photons. The g and w gravitons are the "slow" gravitons; their field equations go as d/dt, like the diffusion equation or the Schrödinger equation. Among other effects, g and w gravitons are responsible for inertial reference frames (which are an effect of graviton atmospheres) and classical quantum mechanics (which arises from particles diffusing through graviton atmospheres). The field equations for the three new kinds of gravitons follow exactly from Einstein's equation, maintaining the physics of general relativity. But the hypothesis of general covariance (that the laws of physics will have the same form in all reference systems), which is false in classical quantum mechanics, is also false in absolute quantum gravity because the g, w, and S gravitons move in absolute space and time.

Absolute quantum gravity (AQG) and quantum electrogravity (QEG) (poster)

Absolute quantum gravity (AQG) quantizes general relativity. AQG results in three new kinds of gravitons: a scalar g graviton, a vector w graviton, and a matrix S graviton. Quantum electrogravity (QEG) adds electromagnetism to AQG. I believe that QEG is the Grand Unified Theory. I do not believe there is a Grander Unified Theory that adds the weak and strong forces, because so far it appears that the interactions between the AQG gravitons and charged particles can account for both the weak and strong forces. This poster will expand on topics covered in my talk on AQG. It will also include updates on the rapidly progressing theoretical and simulation results in AQG and QEG. Depending on what is ready to be released by the time of the conference, the theoretical results may include: formulas similar to propagators and vertex factors for both AQG and QEG; possible new experimental tests; a periodic table of the particles based on bound graviton states; and a calculation of the fine structure constant. The simulation results may include: a hydrogen atom; rotating galaxies inside an extremal Kerr black hole; a dynamic simulation of the graviton showers in single-particle two-slit diffraction (which looks similar to the Plinko game); and a general purpose AQG/QEG simulator.
