We discuss some recent work in which the non-minimal coupling of gravity with a self-interacting scalar field in the presence of matter can lead to a phase transition when the sign of gravitational interaction changes. It is found that gravity becomes repulsive above a critical temperature which may lie in the range 1024 to 1032K which obtains in the very early universe (10-35 to 10-43 sec) of the standard model. The results are intimately connected with big bang and possible removal of singularity.
