When talking about the evolution of the universe, we are talking about events that take an extremely long time to occur. For this reason, I chose to represent the evolution of time in terms of logarithmic steps:

In this table, each value on the left represents the age of the universe in terms of the powers of 10. A value of 6 means 10⁶, or a million years, and 9 means 10⁹ or a billion years, 12 is a trillion years, and 15 is a thousand trillion (or a million billion, etc).. 36 would be a trillion, trillion, trillion (12 + 12 + 12 = trillion x trillion x trillion)..
