A Brief and Elementary Note on Redshift

Authors: José Francisco García Juliá
Comments: 5 Pages.

A reasonable explanation of both redshifts: cosmological (without expansion of the universe) and intrinsic, is given using a single tired light mechanism. In the first case, the redshift is produced because the light interacts with microwaves. In the second, the interaction is with radio waves. And all this is compatible with a static universe with a space temperature of 2.7 ^oK.

A Pervasive Electric Field in the Heliosphere (Part II)

Authors: Henry D. May
Comments: 7 pages

In Part I of this paper [1] it was proposed that a static electric potential of about +800 MV is present in the heliosphere, sustained by the continual inflow of galactic cosmic ray (GCR) protons. Charge neutralization cannot occur because the solar wind and magnetic fields allow more protons than electrons to pass through the termination shock (TS) deeply into the heliosphere. The result is a quasi-static electric field, at dynamic equilibrium, inside the heliosphere. This paper adds some important details that were not included in Part I, and makes some clarifications. The presence of the heliospheric electric field opens up the possibility of accounting for the Pioneer Anomaly, and also the anomalous cosmic rays, as caused by electric fields.

On Planetary Electromagnetism and Gravity

Authors: Ashwini Kumar Lal
Comments: 10 pages, 2 figures, new hypothesis for gravitation ; 'Published in International Journal of Astronomy and Astrophysics (USA) , 2011, vol.1, no. 2, pp. 62-66'

Study of the interiors of the various terrestrial planets, as presented in the paper, leads to the possibility of planetary gravity being linked to the electromagnetism generated in the planetary interiors. Findings of the study undertaken suggest that Earth�s gravitational attraction may be attributed to magnetic coupling experienced between Earth's electromagnetism and all the earthly objects � electrically charged or uncharged. More precisely, terrestrial gravity is deemed to be outcome of the bound state of the planetary electromagnetism.

Big Bang Model? : A Critical Review

Authors: Ashwini Kumar Lal
Comments: 26 pages, 5 figures, minor modification, published in 'Journal of Cosmology' (USA), 2010,Vol.6, pp.1533-1547

Inflationary Hot Big Bang Model is the generally accepted theory for the origin of the universe. Nonetheless, findings of the observational astronomy as also the revelations in the field of fundamental physics over the past two decades question validity of the 'Big Bang' model as a viable theory for the origin of the universe. This paper examines a few of the various factors which undermine the Big Bang theory, including the organization of galactic superstructures, the Cosmic Microwave Background, redshifts, distant galaxies,age of local galaxies, and the gravitational waves.

A Theory of Unified Gravitation

Authors: Gil Raviv
Comments: 255 Pages.

The theory presented here, entitled the theory of unified gravitation, holds that the nuclear strong interaction and gravitation are one and the same force. Detailed and relatively simple mathematics are shown to lead to an explicit strong/gravitational force equation that relies on only three independent parameters, identical to the parameters used in Newton's gravitational theory. The theory is applied on various distance scales to explain a broad range of phenomena, and is shown to provide an unparalleled level of agreement with observations, without requiring an assumption of dark matter, dark energy or inflation. Most notable is its ability to reproduce the morphologies of various types of galaxies and nebulae, as well as the complex structure of Saturn's main body of rings. Additional large-scale phenomena explained by unified gravitation include

• The constant rotation curve observed in spiral galaxies
• The nature of density waves in spiral galaxies
• The mechanism underlying star formation and fragmentation
• The parameters that determine galactic (or nebular) morphology and classification
• The clustering of nearby galaxies, repulsion between distant galaxies, and the creation of galactic voids
• The accelerated expansion of the universe
• The cause of the observed redshift periodicity
• The mechanism responsible for the creation of galactic and stellar wind
• The sudden expansion of gas and matter observed in novae and supernovae
• The formation of planetary ring systems and the composition of planets
• The mechanism responsible for the creation of the planetary and galactic magnetic fields
• A possible mechanism for the creation of the solar corona
• The process of ionization that produces the vast amount of plasma in the universe.

On nuclear scale, the theory is demonstrated to account for the observed weak fall-off of the deep inelastic scattering cross section, and to provide a scaling behavior similar to the observed Bjorken scaling.

Another Explanation of the Redshifts of the Pair Quasar-Galaxy NGC 7319

Authors: José Francisco García Juliá
Comments: 2 Pages.

The excess of redshift of the quasar might be produced in its interior by the transference of heat from the light waves to the radio waves.
