In the present work, by moving from the assumption that the Sun (and all the massive bodies) produces, starting from a certain distance from it, attractive and repulsive gravitational forces at the same time, giving life to the movement of the planets around the Sun according to the same principle of pendulum, I managed to derive a perihelion precession formula, a black hole radius formula and, above all, a formula of the atomic nuclear radius, which was missing until now, all in excellent agreement with the observation and in a completely independent way of the Einstein’s theory of relativity.I have also shown that the nuclear radius formula can also be successfully used to predict the radius of neutron stars.Moreover I have found — always through the same principles that allowed me to achieve the above results, in particular through the modification of the Newtonian gravitational potential, in turn due to the different modus-operandi of gravity force — a formula of the non-decreasing orbital velocity of galactic stars, without considering dark matter.Then I have demonstrated the black hole is composed only of protons, and that it’s similar to the nucleus of the atom and, analogously, the galaxy is similar to the atom, since the stars moving around the central nucleus in the same way as the electrons move around the atomic nucleus. I have also found another similitude among atomic nucleus, black hole and neutron stars, namely the self-orbiting phenomenon existing in all the cases.From the mathematical findings obtained in the present work it has also emerged the existence, both at the microscopic and the macroscopic level, of the gravito-electric force (or, if one prefers, electro-gravitational force), resulting from the fusion of the gravitational force with the electrostatic one, working exactly in accordance with Newtonian mechanics, although modified by the introduction of a repulsive force in addition and in opposition to the attractive one, that makes us understand the universe works always in the same way, both in macro and in micro. Furthermore, by means of the theory here proposed, it has been possible to find a theoretical foundation to the Planck constant, to derive the photon mass, to derive the electron orbital radius, inner and outer, as well as to prove the existence of the gravito-electric radiations.It is also emerged the existence of the universal principle of specific asymmetry between gravitational potential energy and kinetic energy, as a cause of nuclear energy E = mc^2.In this perspective, the present work can represent a potential unifying way between the macrocosm and microcosm mechanics.

The Stability

In the present work we assume that in the atomic nucleus the gravitoelectromotive force (F_ge=GKMm/R^2) acts as responsible for the stability of nucleus and for the nuclear size, and that the potential energy related to this force be given by the ratio F_ge/2πR with R equal to the nuclear radius observed in the electron scattering experiments, obtaining surprising outcomes.The new approach offers an occasion for discussing about the physics and chemistry foundations, in particular about the meaning of the gravitational potential energy and about the nature of the atomic nucleus, which perhaps should be reconsidered in deterministic terms, rather than probabilistic ones.

This chapter explores the ways that accretion onto a black hole produces energy and radiation. As material falls into a gravitational potential well, energy is transformed from gravitational potential energy into other forms of energy, so that total energy is conserved. Observing such accretion energy is one of the primary ways that astrophysicists pinpoint the locations of potential black holes. The spectrum and intensity of this radiation is governed by the geometry of the gas flow, the mass infall rate, and the mass of the accretor. The simplest flow geometry is that of a stationary object accreting mass equally from all directions. Such spherically symmetric accretion is referred to as Bondi-Hoyle accretion. However, accretion flows onto black holes are not thought to be spherically symmetric—the infall is much more frequently in the form of a flattened disk.

We analytically work out the perturbation Δρ induced by the Kehagias–Sfetsos (KS) spacetime solution of the Hořava–Lifshitz (HL) modified gravity at long distances on the two-body range ρ for a pair of test particles A and B orbiting the same mass M. We apply our results to the most recently obtained range residuals δρ for some planets of the solar system (Mercury, Mars, Saturn) ranged from the Earth to effectively constrain the dimensionless KS parameter ψ0 for the Sun. We obtain [Formula: see text] (Mercury), [Formula: see text] (Mars), and [Formula: see text] (Saturn). Such lower bounds are tighter than others existing in the literature by several orders of magnitude. We also preliminarily obtain [Formula: see text] for the system constituted by the S2 star orbiting the supermassive black hole (SBH) in the center of the galaxy.

Dark energy is thought to be very homogenous, not very dense and it is not known to interact through any of the fundamental forces other than gravity. In this research work, we use analytical method to find a model that may possibly relate dark energy to gravitation. After some plausible analyses, we obtain a relation,    where µ is Gravitational potential energy,  is the mass of galaxy,  is mass of earth, Λ is dark energy,  is receding velocity,  is Hubble’s constant and Ro  is the distance measured from the point of observation and the galaxy. Moreover, we estimate K =  for various galaxies, finally, the relation µ ∝ Λ, indicates a direct relationship between Dark energy and Gravitation.

The question concerning the existence of the gravitational force of Galaxies is put in doubt by the authors of the article. The article deals with the fact that gravity is mutual magnitude, if the mass of one of the bodies is close to zero, and the force of gravity common to the two bodies tends to zero. One body does not have gravity. Also, in the article, the authors attempt to prove that the Sun and Jupiter have a huge force, since they are massive bodies in themselves and they also move at low speeds. The authors come to the conclusion that if the Galaxy had gravity, all its stars would have been knocked together long ago. The authors also prove that friction forces always exist. And the frictional forces prevent even rectilinear motion by inertia, the body will stop, continuing to rotate around its axis, if the body has satellites. The authors emphasize that if the body moves, it means that there is someone who moves now, or there is, or was someone who moved before, and it, those-lo, moves by inertia.

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

There are eight columns in the Periodic Table. The eighth column is comprised of the rare gases, so-called because they are the rarest elements on earth. They are also called the inert or noble gases because, like nobility, they do no work. They are colorless, odorless, invisible gases which do not react with anything, and were thought to be unimportant until the early 1960s. Starting in that era, David Fisher has spent roughly fifty years doing research on these gases, publishing nearly a hundred papers in the scientific journals, applying them to problems in geophysics and cosmochemistry, and learning how other scientists have utilized them to change our ideas about the universe, the sun, and our own planet. Much Ado about (Practically) Nothing will cover this spectrum of ideas, interspersed with the author's own work which will serve to introduce each gas and the important work others have done with them. The rare gases have participated in a wide range of scientific advances-even revolutions-but no book has ever recorded the entire story. Fisher will range from the intricacies of the atomic nucleus and the tiniest of elementary particles, the neutrino, to the energy source of the stars; from the age of the earth to its future energies; from life on Mars to cancer here on earth. A whole panoply that has never before been told as an entity.

AbstractThe gas evolution of a typical Dwarf Spheroidal Galaxy is investigated by means of 3D hydrodynamic simulations, taking into account the feedback of type II and Ia supernovae, the outflow of an Intermediate Massive Black Hole (IMBH) and a static cored dark matter potential. When the IMBH’s outflow is simulated in an homogeneous medium a jet structure is created and a small fraction of the gas is pushed away from the galaxy. No jet structure can be seen, however, when the medium is disturbed by supernovae, but gas is still pushed away. In this case, the main driver of the gas removal are the supernovae. The interplay between the stellar feedback and the IMBH’s outflow should be taken into account.

Abstract The formation and stability of collisionless self-gravitating systems is a long standing problem, which dates back to the work of D. Lynden-Bell on violent relaxation, and extends to the issue of virialization of dark matter (DM) halos. An important prediction of such a relaxation process is that spherical equilibrium states can be described by a Fermi-Dirac phase-space distribution, when the extremization of a coarse-grained entropy is reached. In the case of DM fermions, the most general solution develops a degenerate compact core surrounded by a diluted halo. As shown recently, the latter is able to explain the galaxy rotation curves while the DM core can mimic the central black hole. A yet open problem is whether this kind of astrophysical core-halo configurations can form at all, and if they remain stable within cosmological timescales. We assess these issues by performing a thermodynamic stability analysis in the microcanonical ensemble for solutions with given particle number at halo virialization in a cosmological framework. For the first time we demonstrate that the above core-halo DM profiles are stable (i.e. maxima of entropy) and extremely long lived. We find the existence of a critical point at the onset of instability of the core-halo solutions, where the fermion-core collapses towards a supermassive black hole. For particle masses in the keV range, the core-collapse can only occur for Mvir ≳ E9M⊙ starting at zvir ≈ 10 in the given cosmological framework. Our results prove that DM halos with a core-halo morphology are a very plausible outcome within nonlinear stages of structure formation.
