... • We start with small distances we can effectively measure with a ruler. • Next step in the design is to figure out that the “parallax” can tell us distances. • Parallax is the effect of noting you can discern the distance to an object if you can measure how much it appears to move around as you do. ...

Chronology of the universe
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology, the prevailing scientific model of how the universe developed over time from the Planck epoch, using the cosmological time parameter of comoving coordinates. The model of the universe's expansion is known as the Big Bang. As of 2015, this expansion is estimated to have begun 13.799 ± 0.021 billion years ago. It is convenient to divide the evolution of the universe so far into three phases.
