Welcome to the website of
The Group of Gravitation & Cosmologyat University of
the Punjab
Sir Isaac Newton described gravity as an instantaneous and invisible force between two objects. But Newton's laws are inaccurate when describing the gravity produced by very massive objects, such as black holes or neutron stars. Einstein devised a completely new description of gravity. First, he realized that objects in the universe exist in three dimensions of space and one of time. He then combined these into a fourdimensional spacetime. At present the area of relativity is arguably one of the most exciting and rapidly advancing fields in the physical sciences; over the past two decades, a watershed confrontation has been developing between mathematical models of the early universe and new observational data. Major developments are becoming common place. The purpose of this Group is to advance the scientific understanding of our universe in Pakistan, developing cosmological theories that are both mathematically consistent and observationally testable. The Group of Gravitation and Cosmology is a part of Department of Mathematics which in turn is part of Faculty of Sciences at University of the Punjab. It was suggested by Prof. Muhammad Sharif during an International Conference on Relativistic Astrophysics which was organized by Department of Mathematics to announce the relativity group within the department officially. In recent years, the groupâ€™s main effort has been towards the discussion of thermodynamics, inflation, gravitational lensing with the viable universe models. Furthermore, the effects of electromagnetic field on selfgravitating star configuration have also been investigated.
