Cosmology 101

Since this is Cosmology 101 not Personality 101 let's try to get back to the OP.cavediver or Son Goku: If it's too early for this depth of discussion please say so, but the OP specifically asked for points on inflation.One slant on the mechanism includes a scalar field energy difference (kinetic v potential) exerting negative pressure with GR saying under such negative pressure gravity becomes a repulsive force. Another hypothesis posits a scalar field of inflatons or a combination of Higgs fields (?)Can either of you enlighten us on these hypotheses?
