Finite Screen Spacetime(FDS--G1) Complete Series presents a finite-screen entropy-response framework for gravity and late-time dark-sector residuals. The series develops Finite Screen Spacetime as a bridge program in which the primitive gravitational object is a finite causal-screen entropy ledger, and geometry is treated as the integrable hydrodynamic response envelope of that ledger. The archiv…

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and reveal the ultimate fuzziness of time

From the point of view of quantum physics... Could physicists agree what matter is? We see it, we describe it yet it resists intuitive understanding. Is matter really just energy and measurement, decoherence, splitting, whatever process that brings out single outcomes aka "matter"?

The present work introduces a unified phenomenological framework for radiation-matter interactions grounded in the deterministic kinematics of a continuous elastic vacuum medium. By redefining the photon as a unitary bidirectional field event rather than an independent wave packet, the model systematically resolves the historical localization paradox without introducing free parameters or alterin…

I have been looking at the one-dimensional infinite square well, but specifically centered about the origin, so that the boundary conditions are $$\psi(-a)=\psi(a)=0.$$ For the most part, I understand ...

_Synthese_. forthcomingIt is often said that time vanishes in quantum gravity. One general approach to quantum gravity accepts this fundamental timelessness but seeks to derive time’s emergence at a non-fundamental level. To better assess such approaches, I develop the criterion of physical coherence and situate it in context by applying it to two programs for time’s emergence, drawing from recen…

The world hasn’t yet embraced quantum computing because the technology hasn’t overcome a fundamental issue: Noise. It causes quantum bits (qubits), building blocks of a quantum computer, to lose their information. In a recent study in Nature Electronics, a team led by Dafei Jin, an associate professor of physics in the Department of Physics and Astronomy at the University of Notre Dame, and colla…

The Pauli exclusion principle states that no two identical fermions can occupy the same complete quantum state. In standard physics, this is encoded by antisymmetric fermionic wavefunctions and, in relativistic quantum field theory, by the spin-statistics theorem under assumptions such as Lorentz invariance, locality or microcausality, and positive energy. X4 does not replace that theorem. Instea…

In the Collection ”Quantum Gravity” the first article presents a new method for constructing quantum gravity, based on the equations of Einstein’s general theory of relativity. It is shown that the natural space-time boundary is the Planck length. A new uncertainty relation betweenthe gravitational radius of a particle and its position has been found. The basic equation of quantum gravity has bee…

Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the direction of rotation can unexpectedly flip as momentum is transferred. The strange reversal happens because of the crys…

The definition of spinors that speaks to me the most is as the elements of the spin representations of the double cover of the special orthogonal group. However I would also like to make sense of ...

Complete theoretical framework for fuel-free propulsion using Floquet-type time crystals based on NV centers in isotopically purified diamond. Version 6.2 restructures the limitations section into Stage 1 (table-top experiment) and Level 3 (hull-scale implementation) categories. Includes formal proof of net momentum asymmetry from first principles (Floquet perturbation theory + time-reversal symm…

We present a geometric derivation of Quantum Chromodynamics (QCD) within theKoenig framework of dimensional flow and icosahedral invariants. The gauge groupSU(3) emerges from the three golden rectangles of the icosahedron, with 8 gluonsidentified as the complement of 12 fermions in the 20 icosahedral faces (20 = 8 + 12,exact). Confinement is reinterpreted as a dimensional-flow phenomenon: quarks …

Dynamic Boundaries as the Generative Structure of Reality proposes that distinguishability, rather than spacetime itself, is the primary condition underlying physical reality. Space and time emerge secondarily through continuously interacting dynamic boundaries that stabilize distinguishable structure against dissolution into continuity. Under this framework, quantum behavior, relativistic distor…
