Abstract: The most important mile stone in the development of the Big Bang cosmology is the Hubble Law, which shows a roughly linear relationship between the redshift of the spectral lines from a galaxy to the distance from it to earth. Hubble interpreted the phenomenon as a Doppler shift effect due to the recession motion of the galaxy, which inevitably led to the picture of an expanding universe created from a singularity about 15 billion years ago. The Big Bang theory has many well known fundamental problems such as the horizon problem, the geocentric nature of the theory, the extreme violation of the law of mass and energy conservation, the extreme violation of the constancy of the speed of light, and the extreme instability of the mathematical model. The Dispersive Extinction Theory (DET), which we have developed through a number of recent publications, however, interprets the cosmic redshift as the result of dispersive absorption and scattering of the star light by the intergalactic space medium during its propagation towards the earth. The theory is based on the well known phenomenon that is responsible for the star-reddening and for the sky to be blue. since the space medium absorbed and scatters the blue light more than it does the red component, the Gaussian peak of a spectral line would shift towards the red side, and therefore the redshift. No global galactic movement is needed in this theory to explain the cosmic redshift, and therefore, DET allows a stable non expanding universe, infinite in space and time. The new theory is free of all the well known problems intrinsic to the prevailing Big Bang Theory. Not only DET offers an alternative cosmology, it also contains rich physics never known to astrophysics community before: DET predicts that the cosmic redshift not only roughly linearly dependent on the distance, but is also proportional to the square of the linewidth and inversely proportional to the cube of the wavelength. This linewidth and wavelength dependence may be used to vindicate or falsify either one of DET and Big Bang cosmology against the other. DET also offers an interpretation of the abnormal redshifts of the quasars: The incredibly high redshifts of the quasars may well be due to the large linewidths typical of the quasars. It also indicats a possibility that much of the identification of the redshifts might be wrong, due to the omission of the linewidth and wavelength dependence of the redshift. It also offers an explanation of the abnormally great redshift of the quasars: It could be caused by the wide linewidths.
Brief biography of the speaker: Dr. Ling Jun Wang graduated from the University of Delaware, USA in 1984. He then worked as postdoctoral research associate at Wesleyan University and Oak Ridge National Laboratory. He then joined Vanderbilt University as a research associate professor. In 1990 Dr. Wang joined the faculty of University of Tennessee at Chattanooga in 1990 while cooperating with Oak Ridge National Laboratory, Argonne National Laboratory, and NASA Marshal Space Center as research associate and visiting professor. Being both theoretical and experimental physicist, his research work ranges from atomic physics, fusion physics, solid state physics, particle physics relativity and cosmology. His recent research interest is focused on the rotational behavior of Einsteinian spacetime, geocentric nature of the Big Bang theory and the Dispersive Extinction Theory of cosmic redshift, which he has developed in the recent years. He is author of about 60 papers published in peer reviewed international journals, conference proceedings, and invited book chapters. Dr. Wang was a previous Plenary Speaker of a WSES Meeting
