One of the aims of modern cosmology is to understand the evolution of the Universe from its genesis. Many of the observational tools used in mapping the evolution of the Universe center on the use of astrophysical objects whose intrinsic properties are well understood. These standard candles and rulers have, with measurements of their observed characteristics and knowledge of their intrinsic characteristics, allowed the observable Universe to be explored. In this work we adopt standard clocks to explore the evolution of the Universe. We record the age of a population of quiescent, passively evolving galaxies estimated at different epochs. From this chronology we are able to trace the evolution of the Universe through redshift and place constraints on ΛCDM cosmological models.
