Abstract: Analytical and statistical methods,with some plausible assumptions, have been used in this work to show presence of dense medium around compact steep-spectrum sources in our sample. This is done by carrying out regression analyses using our estimated jet’s internal densities (n_j ) and some other source parameters for possible deductions. Results indicate that n_j-D and n_j-n_e data (where D and n_e are respectively, observed source linear size and ambient medium density) show strong correlations and yield power-law relations of the forms, n_j~D^(-3.54±0.02) and n_j~n_e^(1.68±0.08). A comparison with obtained theoretical relations suggestively indicates presence of dense gases around these sources. In addition, a simple linear regression analysis of ν_p-n_j data shows that jet’s particles may be responsible (in addition to the ambient gases) for the observed spectral turnover characteristic of compact steep spectrum sources.

Abstract: The nature of the universe is such the speed of light in a homogeneous medium is a constant that is determined by the permittivity and permeability of the medium including a vacuum; a path of light appears to depend on the observer’s frame of reference. This led to believe that the time depends on the observer’s frame of reference, which is an inherent assumption in the Special Relativity. The Special Relativity further stipulates that the mass depends on the observer’s frame of reference. The both time dilation and mass dilation of moving objects are the foundation of the Special Relativity by human design; they are not inherent characteristics of the universe. In the Universal Theory of Relativity the time and mass are absolute. When an object is in motion, time and mass remain unchanged; however the geometry of the object contracts in all directions leading to the volume contraction. Since mass is absolute, the mass-density dilates due to the volume contraction. When an object reaches the speed of light, its mass-density reaches infinity while the mass remains unchanged; this gives rise to extreme close proximity gravitation within the boundary of the object at rest, which is the event horizon. In the Special Relativity, the contraction of the volume of a moving object is not taken into account, and hence the increase in gravity of a moving object is erroneously attributed to mass dilation, which led to the celebrated mass-energy relationship that does not hold when the time and mass are absolute. When time and mass are absolute what prevails is the mass-density and energy-density relationship. When an object is in motion, its gravity dilates as a result of volume contraction while the time and mass remain the same. In the Special Relativity, the time, mass, and length, all depend on the observer’s frame of reference, and hence the corrections have to be made to all. However, in the Universal Relativity, only the change in the geometry has to be taken into account. An object moving in space at an acceleration g, and an object at rest under gravitation g are not equivalent; the principle of equivalence does not hold. The gravity does not bend light, only a density gradient in a medium does. A second is always a second, and mass remains the same irrespective of the speed and the location of the object in the universe.
