Abstract

The scale invariant model of Newtonian gravity by Barbour, Koslowski, and Mercati (2014, 2013, 2015) purports to solve the problem of the arrow of time, but has received minimal philosophical analysis. This omission is amended in the
present work, in which I describe how the model manages to derive asymmetric behaviour from symmetric physics. The Janus point structure of the proposed solution holds significant preliminary promise for deriving asymmetry from symmetry.
However, the proposal does not recover sufficient supervenience relationships between various other arrows of time to regard the problem as being solved. I propose a line of research which defines statistical mechanics within the BKM model, which would be a significant advance toward a satisfactory solution.
