On The Origin Of Time by Thomas Hertog

A readable exploration of how time may emerge from a quantum description of the universe rather than existing as a fundamental background, arguing that the classical “beginning” is replaced by a finite quantum state that gives rise to spacetime and the arrow of time; it develops ideas from quantum cosmology (including the no-boundary approach) to show how particular initial quantum conditions, together with inflationary dynamics, can produce the observable large-scale structure and yield testable predictions, thereby reframing the origin of time as a scientific, observationally relevant problem.
