However, these should not be any problems as we could use well-established modelling technique of scaling so that we are solving the scaled-down NSLE with much more convenient numbers. If SI units are used, we would be solving NLSE with system parameters as small as 10 −10 or less. We accept the fact that we are dealing with distances not just measured in light year but it could be in billions of light years. The transmission is therefore governed by the well-known nonlinear Schrödinger equation (NLSE). Light as a form of electromagnetic waves in their propagation through space must interact with whatsoever material present, no matter how thinly it is distributed. In this paper, we accept the fact that the space is not a complete vacuum. Therefore, this theory is closer to just being an empirical correlation between the observed redshifts and distance. Although there are qualitative arguments presented on how the loss could have taken place, there is no concrete evidence from laws of physics that such an exponential relationship should exist. The proposed theory is that the loss varies exponentially from distance travelled. Although the space is very thinly populated by those particles, the cumulating effect through an exceedingly long cosmic distance must result in a detectable loss of energy that is manifested itself as redshifts. The idea behind this theory is that, when light is travelling through the cosmic space, it must lose energy through interaction with particles, mostly hydrogen atoms, or other minute particles. There is a different theory that is much less known and much less accepted by researchers. Many would find it difficult to understand the difference between peculiar velocity, the velocity at which an object moves through space, and recessional velocity. Mathematically, there is no problem to used recessional velocity, based on the assumption of an expanding space between an object and its observers this conception is, however, difficult to be accepted physically. Also, based on this theory, recessional velocity of an object is proportional to the distance from observers it means that for a distant object, its velocity could not just greater than but also hundreds or more times the speed of light. Quasar ULAS J1342+0928 is known to have a redshift of 7.54, which corresponds, according to Hubble model, to a distance of approximately 29.36 billion light-years from Earth (these distances are much larger than the distance light could travel in the universe’s 13.8 billion year history). One of the problems with Hubble model is the large redshifts observed in quasars. If Doppler Effect due to velocity is taken into consideration, it could be shown that redshift is directly and approximately related linearly to the distance from the stars to the observers. The current most acceptable model is based on Hubble’s law which was started from observations of the linear relationship between the velocity and distance of stars. Shift of spectral lines in the light spectrum from distance stars has been extensively observed and measured by researchers over many centuries. ![]()
