Hubble's law has been the subject of study in recent years, the problem of the Hubble Tension with respect to the existence of various values of the parameter and the results of dark energy with respect to a change in the trend of the parameter value about 6.5 billion years ago have brought it into play. Through the study of the Rh=ct universe model and by going deeper into it, we have addressed these problems. This model of the linear expansion universe, Rh=ct, studied in recent years by Professor Fulvio Melia, is one of the best to respond to the new challenges posed by experimental research in astrophysics. For this reason, we have opted for this model to apply our hypothesis regarding the use of relativistic Doppler equations in calculating the speed at which galaxies move away from the observation point, the Earth. This has allowed us to develop, within the framework of this model of the universe, a new equation that relates the Hubble parameter with the red shift. The result, in light of their predictions, appears to be consistent with some of the issues raised by the Hubble Tension and Dark Energy.

Our sun’s ethereal corona is an object of awe,especially during full eclipses. Its extreme heat is apuzzle seemingly without any elegant explanation.However, there is an elegant explanation that hasbeen resolutely ignored. This update shows whatthe best of solar science has, and has not,discovered so far. In sharp contrast, five seminalessays linked herein provide elegant and coherenttheory to clearly explain what is going on.

Our Universe is surrounded by Primary Energy and Primary Matter that is pulling, that is attracting, our Universe causing our Universe to expand at an increasingly rapid rate.

The study of supermassive black holes has significantly advanced our understanding of galaxy structures, yet fundamental questions remain, particularly concerning the structure and dynamics of massive black holes. This article addresses the core structure of massive black holes, defined as those originating from supernova events. Integrating the concept of "Dachus density," a state of maximum matter density, I propose that the core of all massive black holes exists at this density. The research investigates the size of these cores and their event horizons, using Cygnus X-1 and Sagittarius A* as examples. Calculations reveal that the core size is exceedingly small compared to the overall black hole, with the core's volume being up to ~155 orders of magnitude smaller than the event horizon volume in the case of Sagittarius A*. The article briefly explores the implications of a rotating Dachus core on the black hole's structure, including the "mantle" region between the core and the event horizon. The discussion extends to absolute zero temperature, asserting that for a non-spinning, static Massive black hole, the temperature of its core reaches 0[K] as in this state, particles do not move in relation to each other and do not have any kinetic and in particular rotational Energy.

MOND, Modified Newtonian Dynamics, provides an alternative to dark matter and is successful at explaining many astronomical scenarios including the flat rotation curves of disk galaxies. MOND operates at very low accelerations and can be interpreted either as a modification of Newton's law of inertia, or as a modification of Newton's law of gravity. In this paper we recast MOND in terms of our conjecture of a weighting function that determines the dynamical mass from the baryonic mass. This enables us to preserve both Newton's law of inertia and Newton's law of gravity.

The term "speed of light" is often inaccurately used in two fundamental ways:1.Incomplete Label: The correct term is "speed of light in a vacuum." Light travels slower in mediums such as air, water, and glass, leading to phenomena like Cerenkov radiation [1].2.Historical Misnomer: "Speed of light in a vacuum" is historically rooted. A more accurate term is "cosmic speed limit for massless particles", reflecting Einstein’s insights into its fundamental nature [2] [3].The Variability of the Speed Limit (VSL) hypothesis challenges the established notion of the speed of light as a constant, proposing that this fundamental limit may vary under specific cosmic and quantum conditions [4] [5] [20]. This article synthesizes theoretical frameworks, observational data from cosmology, and experimental insights from astrophysics and particle physics to explore the implications and potential variability of the speed of light [5] [6] [20]. This empirical exploration offers a new perspective on dark matter and dark energy, suggesting that changes in the speed of light under different conditions could provide a more unified and comprehensive understanding of these enigmatic components of the universe [7] [8] [20]. This article delves into the VSL hypothesis, emphasizing its potential for experimental validation and its ability to address outstanding puzzles in cosmology and physics. The focus on testability and falsifiability necessitates collaboration with leading research facilities. This exploration aims to determine the true nature of the speed of light: a universal constant or a locally variable limit.

The existing understanding of the nature of the Coriolis force and centrifugal force raises many puzzling questions. The article proves that these forces can be justified as consequence of the equations Maxwell for gravitomagnetism. It is further shown that the flyby anomaly is a consequence of the influence of Coriolis forces and a method for calculating this influence is indicated.
