In DRUMS, time emerges as the progression of the superfluid phase field:
Where \(\theta(\mathbf{x},t)\) is the phase of the coherent superfluid, and \(\omega\) is the angular frequency of local excitations.
Physical clocks measure time through periodic processes in the superfluid substrate:
Each oscillation of the superfluid phase defines a discrete time unit.
The local flow of time is determined by superfluid velocity gradients:
Where \(\mathbf{v}_{sf}\) is the superfluid velocity field and \(\tau\) is proper time along a trajectory. This reproduces time dilation effects without invoking spacetime curvature explicitly.
Large-scale time evolution corresponds to collective phase changes of the superfluid across the cubic substrate:
The universe’s apparent age arises naturally from cumulative phase evolution.
Microscopic processes are reversible, but macroscopic entropy increase arises from phase disorder in the superfluid:
The gradient \(\partial S/\partial t > 0\) defines the thermodynamic arrow of time.
Within the DRUMS framework, time is fully explained as:
