This manuscript proposes a common baryonic closure for the radial acceleration relation in gas-rich dwarf galaxies, SPARC disks, and CLASH galaxy clusters. The same algebraic closure is retained across regimes, but the effective scale (a_U) is built from local baryonic physics: H I structure in disks, Toomre stability and pressure support in dwarfs, and baryon depletion plus hydrostatic—geometric confinement in clusters. The work shows how the hierarchy (10^{-11}ightarrow10^{-10}ightarrow10^{-9}
{m m,s^{-2}}) can be organized through baryonic geometry, effective participation, and confinement, rather than by imposing a single universal acceleration scale.

Cosmic rays are an important non-thermal component of active galactic nuclei (AGN) and may contribute significantly to the pressure balance and energy transport within galactic nuclei. The efficiency of cosmic-ray confinement and survival strongly depends on the surrounding plasma conditions, radiation fields, particle densities, and magnetic environments. In this study, we compare the dominant cosmic-ray energy loss mechanisms in quasars and Low-Ionization Nuclear Emission-line Regions (LIN ERs). We focus on photopion production, proton-proton collisions, magnetic diffusion, and synchrotron cooling processes. In quasar environments, intense radiation fields and strong magnetic activity enhance relativistic particle energy losses through photopion interactions and synchrotron emission. In contrast, the weaker radiation and magnetic environments of LINERs mayallow cosmic rays to survive for longer timescales and contribute more effectively to sustained cosmic-ray pressure. Using characteristic physical parameters from both AGN classes, we discuss how environmental differences influence cosmic-ray evolution and pressure behavior. Our results suggest that quasars experience more efficient cosmic-ray energy dissipation, while LINERs provide comparatively stable conditions for cosmic-ray confinement.

We present a theoretical framework in which gravity becomes repulsive when the gravitational force reaches a maximum value, known as the Planck force. This inner flip from attractive to repulsive gravity at extreme field strengths resolves three fundamental problems in physics. First, it explains why the Big Bang did not immediately re-collapse under its own gravity: when the entire massof the observable universe was compressed within a radius of approximately 24cm, the gravitational force exceeded Fmax, triggering repulsive gravity and driving explosive expansion. Second, it eliminates the singularity inside black holes, replacing the infinite-density point with a finite-density core at the inner flip radius rmin. Third, it establishes a minimum mass for black hole formation of approximately 250 grams, below which the repulsive core extends beyond the would-be event horizon, preventing collapse. Thisminimum mass directly contradicts the standard primordial black hole hypothesis, which allows black holes of arbitrarily small mass. Our theory uses only two well-established constants G and c and the SI base unit of 1 kg, requiring no new particles, no inflaton field, and no exotic matter.

Modern physics is increasingly encountering the limitations of exact symmetry frameworks when attempting to explain the complex, scale-dependent, and emergent structures observed throughout nature. Similar self-organized and self-similar patterns repeatedly appear across vastly different physical scales, ranging from atomic orbitals, crystal lattices, and plasma filaments to atmospheric vortices, planetary surface structures, galactic distributions, and the large-scale cosmic web, suggesting the existence of deeper universal organizational principles. In this work, we propose an extended interpretation of the Unified Fractal Quantum Field Theory (UFQFT) in which spacetime is not an empty geometric background, but a space-filling neutral fractal resonance field dynamically organizing matter through resonance coherence and scale-dependent geometric interactions. Within this framework, particles, forces, gravity, and large-scale structures emerge from the resonance dynamics of fundamental energy (Φ) and charge (Ψ) fields embedded in fractal spacetime characterized by a non-integer dimension D≈2.7. Symmetry is therefore interpreted not as an exact static invariance, but as an emergent consequence of dynamically stabilized resonance configurations formed within the underlying fractal neutral field. Similar to the alignment of charged particles along magnetic field lines, matter distributions across nature may evolve toward geometrically stable configurations defined by resonance-guided organization. Consequently, the repeating symmetric and quasi-symmetric structures observed from microscopic quantum systems to cosmological filament networks may represent scale-dependent manifestations of the same underlying fractal field geometry. The framework further provides conceptual connections between generalized symmetry, emergent spacetime, dark matter, dark energy, holographic organization, and large-scale cosmological structure formation, offering a unified geometric interpretation for the emergence of order and symmetry across the universe.

The Tensional Structure Principle (TSP) proposes that the universe is composed of a nonlocal network of Planck scale elements under tension. Spacetime emerges as the stable equilibrium configuration of this network. Gravity arises not as curvature of a manifold or as a field, but as the gradient of tension between adjacent structural elements. This framework offers a physically grounded alternative to geometric and field based descriptions of gravitation.

Direct imaging of Earth-like exoplanets demands a contrast ratio of 10^10—far beyond conventional ground-based coronagraphy. We present a unified atmospheric architecture that eliminates the need for a dedicated space observatory.Its centerpiece is the Drone-Borne Synthetic Aperture Starshade (DSAS): a multi-ring UAV formation at staggered altitudes, each ring suspending programmable electro-optical fabric that acts simultaneously as an adaptive occulting mask, a multi-plane Fresnel zone plate, and a distributed wavefront sensor. Real-time apodization via the Huygens-Fresnel integral, combined with an internal Optical Vortex Phase Mask (OVPM), is projected to deliver 10-10 contrast at the detector.As a complementary opportunistic channel, Trans-Neptunian Object (TNO) occultations observed near Radial-Velocity Stationary Points with pre-positioned linear telescope arrays convert rapidshadow transits into scientifically viable integration windows.

We propose that Odd Radio Circles (ORCs), the giant ring-like radio structures discovered by ASKAP cite{Norris2021}, can be interpreted as local, observable manifestations of rheological activation within the Cosmological Dissipative Residual (CDR) framework developed across Papers I--IV. In this picture, major galactic mergers or intense starbursts release rest-mass energy through Einstein's mass-energy equivalence ($E = epsilon M_{m event} c^2$), inflating an expanding plasma bubble. As this bubble expands into the surrounding cosmological residual medium ($w_{m res} approx -1$), a sharp velocity and density gradient develops at the interface, generating significant shear ($sigma sim 10^{-14}$--$10^{-13}$ s$^{-1}$). This shear activates the pseudoplastic (shear-thinning) rheological response of the residual (Paper II), producing anisotropic stress $pi^{ij}$ that dissipates energy through turbulent processes. Part of this dissipated energy is converted into the isotropic residual component, contributing locally to the cosmological residual density, while another fraction accelerates electrons to relativistic energies via second-order Fermi processes, powering the observed synchrotron emission that forms the bright radio ring. Order-of-magnitude calculations using realistic astrophysical parameters demonstrate that modest conversion efficiencies are sufficient to sustain the observed radio luminosities ($10^{40}$--$10^{42}$ erg s$^{-1}$) and provide a concrete channel for the general production term $beta_{m prod}(z)$ introduced in Paper IV. ORCs thus function as natural, accessible laboratories where the transition from anisotropic stress to isotropic residual can be directly studied. This interpretation unifies phenomena across vastly different scales — from late-time cosmic acceleration and emergent dark matter (Papers I and II) to strong-field jet launching (Paper III) and continuous residual production (Paper IV) — within a single effective medium. It makes clear, falsifiable predictions regarding polarization morphology, correlations with star formation history, and possible weak lensing shear excesses, offering a promising avenue for future multi-wavelength tests with ngEHT, Euclid, and the Roman Space Telescope.
