a billion billion stars is the same order of magnitude scale as a billion billion seconds, which is about the age of the universe. Or, a
billionth billionth second (one attosecind), which is the amount of time it takes for an electron to change orbitals, and also the speed of light across the diameter of a Hydrogen atom.
