Theoretical models of cosmic explosions (such as stellar explosions) and galactic rotation curves are essential cornerstones of astrophysics, serving as primary diagnostic tools for understanding stellar mechanisms, the distribution of matter, and the fundamental structure of the universe. However, in this lengthy research paper, we have provided robust, up-to-date empirical data on stellar explosions and the rotation curve phenomenon, based on modern observations. This objective analysis of observational data has not only exposed the fundamental flaws in conventional models of stellar explosions and rotation curves but also refuted foundational paradigms in astrophysics and cosmology. Alternative models have been proposed.

The aim of this work is to test the novel theory called Dark Matter by Quantum Gravitation theory (DMbQG hereafter) at cluster scale. This theory was initially developed for galaxies and afterward was extended to clusters. The main paper where the theory is developed at galaxy scale is [5] Abarca, M. 2024, also in this paper there are some validation test using the rotation curves of MW and M31. The theory was fully extended to cluster in [2] Abarca,M.2024, also in the paper there are some validation test using data referred to the Local Group and the Virgo clusters. In this work are compiled some test introduced in the both papers and also there are two new tests referred to the Coma cluster, using data published recently. The tests are mainly focused on the turnaround radius, also called zero velocity radius, and its gravitating mass associated, in addition regarding the LG of galaxies there is another important test focused on its virial mass as well. The theoretical calculus has been validated using four papers published by well known team researchers in recent years. Namely the years: 2017, 2018, 2023 and 2025.

The process of magnetic switchbacks contributes greatly to coronal heating and the acceleration of solar wind. It is a weakly collisional plasma process influenced by magnetic field configuration, rather than a result of purely electrostatic Coulomb collisions. This magnetic process is a consequence of magnetic scattering, in which low-energy galactic cosmic rays (3-30 MeV/nuc) interact with solar radiation, and this interaction is more pronounced during periods of heightened solar activity, including the release of Energetic Solar Particles (SEPs). Essentially, when highly modulated Galactic Cosmic Rays (GCRs) collide weakly with the solar radiation, magnetic switchbacks are formed, resulting in a form of anti-Stokes Raman scattering that increases the temperature of a magnetised plasma and accelerates the solar wind. It is unconventional Raman scattering of a highly magnetised plasma involving nonlinear, non-isotropic interactions in which an external magnetic field modifies charged-particle dynamics, producing an optical S-shaped signature. In the presence of a strong magnetic field, Coulomb collisions are significantly altered, forcing them into complex, S-shaped or non-monotonic trajectories rather than the simple hyperbolic paths observed in conventional Coulomb scattering. That is because the magnetic field induces cyclotron motion (gyromotion) which interacts with the Coulomb potential, causing the heavily charged particle to spiral or curve, intersect its asymptotic line, and create a unique S-shape before completing its scattering.

We develop a hierarchical formulation for evaluating gravitational binding energy from the internal organization of matter, volume conservation, and mass--energy equivalence. Rather than relying only on pairwise interaction terms defined relative to infinity, the proposed estimator assigns an intrinsic energy scale to compact configurations of matter. We then test whether the corresponding mass-equivalent contribution can reproduce the effective dark mass inferred in galaxies.We test this formulation using SPARC rotation-curve data together with independent GALEX and SDSS photometric observations. Stellar population mixtures are reconstructed from dynamical information alone, without using photometric data as input, and are then used to predict integrated galaxy colors. The resulting colors show significant correlations with observations, indicating that the reconstructed populations encode non-trivial information about stellar structure.A systematic exploration of the estimator reveals structured regions of high-quality solutions in parameter space. In particular, the results favor a hierarchical recursive interpretation in which class-level binding energies are preserved, while the binding energy associated with the global aggregation of heterogeneous stellar classes may contribute with an effective virial factor. The dynamical reconstruction varies only weakly across a broad range of parameters, whereas the photometric constraints provide greater discrimination between candidate forms.These results suggest that gravitational binding energy provides a physically motivated contribution to the effective dark mass inferred in galaxies, while also explaining why dynamical information can encode stellar population structure.

The provided materials demonstrate an empirical study (Figs. 1-12) identifying mysterious "envelope waves" through the analysis of distance differences at symmetrical points of planetary orbits. Additionally, a rigorous kinematic apparatus [2] has been developed to derive a force law applicable not only to closed ellipses but also to precessing orbits (rosettes).Using the kinematic apparatus from work [2], we can construct a mathematical description of the observed oscillations. The key idea is that the envelope wave in the graphs is a direct consequence of orbital precession, "decomposed" through an original methodology of symmetrical differences.
