Research & Projects

In my masters I have done a project which is the part of my M.Sc. thesis. Since I have keen interest to know about the origin of Universe, due to this I decide to do project in the field of Cosmology for that I choose Dr. Pavan K. Aluri as my project guide who work in the field of Cosmology.

Objectives

Objective of this project was to making a constrain on rotational universe using astronomical data and Godel - Obukhov Space-Time.

Results

A/c to K. Godel universe is rotating along with expansion  and for that  the parameter  a(t) & m, of the Godel-Obukhov space-time must be grater than 1, where a(t) is the scale factor that tells about the expansion of the universe and m tells about the rotational of universe. By using isotropic and anisotropic stress - energy tensor in the Godel-Obukhov space-time we get m = 0, which tells that for such type of stress energy tensor rotation is not possible along with expansion, and for study the rotational behaviour of the universe along with expantion we have to take some other type of stress energy tensor.
