Which arrow is fundamental?
Issue

#104015
How are the different physical time arrows related? Is there one 'master arrow' that gives rise to the others. The two main candidates - the cosmological and thermodynamic arrows - are considered below.

The Arrow of Time
The Arrow of Time ☜A map exploring some issues concerning the nature of time that lie at the boundary of physics and philosophy. The map follows up a talk to the Blackheath Philosophy Forum on 2 April 2011 by Huw Price, Professor of Philosophy and director of the Center for Time at Sydney University.☜F1CEB7

The physics of time
The physics of time☜Is our subjective sense that time has a direction from past to future reflected in impersonal physical processes and laws? Is it better - from the impersonal viewpoint - to look asymmetries in time rather than a direction (to the future) of time?☜FFB597

Other arrows
Other arrows☜A number of additional physical time arrows have been identified: the radiative arrow, the causal arrow, the particle physics (weak) arrow, the quantum arrow. Our main focus is the thermodynamic and cosmological arrows - these other arrows are included for completeness.☜FFB597
