For 10 points, identify this event which occurred roughly fourteen billion years ago and began the existence of the universe.
This event was immediately followed by the mysterious Planck time. Its occurrence can be verified by the fact that matter, at sufficiently large scales, is homogenous and isotropic, as well as by the uniform 2.73 Kelvin temperature of the cosmic microwave background radiation. It was accompanied by a very rapid inflation and soon followed by recombination, during which electrons and protons cooled enough to form atoms.
