A Brief Analysis of de Sitter Universe in Relativistic Cosmology


Assistant Professor, Premier University, Chittagong, Bangladesh.


The de Sitter universe is the second model of the universe just after the publications of the Einstein’s static and closed model. In 1917, Wilhelm de Sitter has developed this model which is a maximally symmetric solution of the Einstein field equation with zero density. The geometry of the de Sitter universe is theoretically more complicated than that of the Einstein universe. The model does not contain matter or radiation. But, it predicts that there is a redshift. This article tries to describe the de Sitter model in some detail but easier mathematical calculations. In this study an attempt has been taken to provide a brief discussion of de Sitter model to the common readers.
