“…When the radii and masses do not correspond, which also are in stars that are much farther away, the rotational values are quite unpredictable. Even so, one does notice larger rotational speeds in larger stars (stars 18,19,20,33). We infer from the above that the farther away the stars are from the observers, the less accurate the readings are.…”

This is the final article in our series dealing with the interplay of spin and gravity that leads to the generation, and continuation of celestial body motions in the universe. In our prior studies we focused on such interactions in the elementary particles, and in the celestial bodies in the solar system. Foremost among the findings was that, along with gravity, matter at all levels exhibits axial spin. We further noted that all freestanding bodies outside our solar system, including the largest such units, the stars and galaxies also spin on their axes. Also, the axial rotation speed of planets in our solar system has a linear positive relationship to their masses, thus hinting at its fundamental and autonomous nature. We have reported that this relationship between the size of the body and its axial rotation speed extends to the stars and even the galaxies. Next, all congregations of matter spin on their axes in the counterclockwise direction; all satellites orbit their mother bodies also in the counterclockwise direction, i.e.: in our solar system, with only rare exceptions, the How to cite this paper: Raghuprasad, P.K.

“…The fundamental units of matter, both structural (fermions, such as quarks and leptons) as well as the force particles, (bosons such as photons) display axial rotation (Padgett & Allen, 2000;Allen, Beijersbergen, Spreeman, & Woerdman, 1992;Coutial, Robertson, Dholakia, Allen, & Padgett, 1998;Liu et al, 2005;Fernandez, 2006;Harris, Becker, Cabral de Menezes, Goodfellow, 2001). This fact alone should serve to remind us about both the origin, and importance of this property of matter.…”

In a prior article we explained how axial spin of celestial bodies interact with mutual gravitation in the phenomenon of synchronous rotation of our moon and the major moons of the gas giants. We also showed how the same complementary interactions could explain both the nonsynchronous (regular orbits) and the negative rotations in Venus, Uranus and Pluto, as well as in the peripheral small satellites of the gas giants. This paper expands on that theme and identifies the various other areas in which these two fundamental and ubiquitous forces cooperate to bring about many other phenomena in the larger universe. Prominent among these phenomena is the role played by the mother bodies’ axial rotation in determining the direction of the orbital motion of their satellite bodies. The other effects include the appearance and maintenance of the spherical shape of large celestial bodies, generation of magnetism in planets, their respective roles in the formation of solar nebulae and proto-planetary disks, and the flattened profile of spiral and elliptical galaxies. Another important finding reported in this paper is the close relationship that exists between the size of planets, as well as the stars, with their axial rotation speeds. This increase of axial rotation speed of celestial bodies in direct proportion to the mass of those bodies, we believe serves to counteract the inward thrust of gravity, in exact proportions and thus help maintain the roughly spherical contour of those bodies. This finding even extends to spiral galaxies, where the axial rotation speed seems to be positively related to the size of the galaxy. This phenomenon and others suggest that spin is a fundamental and purposeful property of matter. Thus, in this paper we stress the important contributions made by the collaborative interactions between the ubiquitous gravity and spin in matter at the level of the fundamental particles, as well as in large celestial bodies, including the largest units in the universe, the galaxies.

“…Superbeams [4][5][6] are based on conventional beam dump techniques for producing neutrino beams. An intense high energy proton beam is directed onto a thick nuclear target producing mostly pions and kaons, which are captured by an optical system of magnetic horns in order to obtain well directed beam of same charge secondaries (see Fig.…”

High-energy and high-beam power accelerators are extensively used for the neutrino physics research. At present, the leading operational facilities are the J-PARC facility in Japan, which recently approached 0.5 MW of the 30 GeV proton beam power, and the Fermilab Main Injector complex that delivers over 0.75 MW of 120 GeV protons on the neutrino target. Besides such type of neutrino superbeams, the concept of neutrino factories offers great promise for particle physics research. In this brief review we present the status and planned upgrades of the J-PARC and Fermilab accelerators and leading proposals for the next generation accelerator-based facilities of both types, their challenges and required and ongoing accelerator R&D programs aimed to address corresponding performance and cost risks.
