Quizplus · Accepted Answer

The first 10^-43 seconds of the age of the universe is called the Planck time, during which time matter was so compressed that all known science fails us. This was followed by the inflationary epoch, where the universe rapidly expanded. The event horizon refers to the point of no return for objects falling into a black hole, and the Hubble time is the age of the universe based on the rate of expansion.
