_English_. 2026This paper proposes that physical reality is fundamentally local, with all observation, causality, and structure emerging through finite propagation within constrained communication domains. Rather than treating reality as globally instantaneous or universally synchronized, the framework argues that every observer exists within a locally updated region shaped by propagation limits,…

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"?

This article develops a metatheoretical claim about a specific class of intellectual operations in foundational physics. It distinguishes between solving an interpretive problem in its own terms, replacing the theory that generated the problem, and dissolving the problem by displacing the ontological presupposition that gave it its shape. The third operation, which the article calls ontological r…

There is currently no good way for astronauts in space to do laundry, but researchers may have finally come up with one: a bright purple jet of microbe-killing plasma

So i always saw those graphical diagrams of blackholes where we can an opening at the top and the cannal goes deeper into the space time fabric revealing its untra massive core but this is a 2d depiction of a 3d model ,Black holes are not circular holes in space time fabric, they... Read more

I am reading Max Tegmark's book Our Mathematical Universe. On page 172, Tegmark wrote the following: "Two waves can pass through each other unaffected, like the circular waves in the water tank in Figure 7.6; at any time, their effects simply add together. In some places, we see peaks of the... Read more

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…

This work investigates the structural relationship between macroscopic plasma spark events generated by industrial welding systems and particle-like signatures reconstructed in high-energy collider experiments. The central objective is to demonstrate that highly organized detector signa- tures, including reconstructed trajectories, resonance-like peaks, apparent decay channels, and statistically …

Consider railroad tracks along which synchronized clocks are placed. Along the tracks, a train is traveling westward (of course in space, “west” is only used to define a specific direction). The train also has clocks synchronized with each other, though naturally not synchronized with the... Read more

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…
