When the amount of energy in a typical jiggle became less than the amount of energy required to hold together some form of composite particle—a proton, for example—those particles formed. When the jiggles of the constituent parts—quarks, in the case of a proton—were no longer sufficiently energetic to maintain them as distinct particles, they stuck together as a composite particle that condensed out of the cosmic soup. Every time a new ingredient of the soup condensed out, there was a burst of entropy—new information was written in the cosmic cookbook.
