Cosmological inflation

Observations in Antarctica with the BICEP2 experiment measuring the polarization of the cosmic background radiation seem to confirm the model of cosmological inflation and the big bang. The inflationary epoch was a practically instantaneous period of the early universe (10^-36 to 10^-32 seg after big bang) where the space expanded much faster than the speed of light. If you haven’t read it yet buy inmediately the book by Lawrence M. Krauss “A Universe from nothing” (…with an introduction by Richard Dawkins).
