The First exact solution to Einstein‟s Field Equations for removing the Initial Singularity by altering the source term in Einstein‟s Field Equations was proposed by me in 1992 and is published in proceedings of Fourth Kerala Science Congress and 125th Anniversary Celebrations of University College, Thiruvananthapuram, Kerala, India.
It was shown that the necessary condition for Non-Singular Solution at the beginning of this Universe is vanishing of physical parameters such as density and pressure of Cosmic Fluid. A detailed version is available at http://arxiv.org/PS_cache/gr-qc/pdf/0106/0106029v1.pdf
In this Theory All Cosmical Parameters are mathematically well behaved at Cosmic time t=0 and the temperature is shown to be 10 to the power of 32 Kelvin at the beginning of this Universe.
