From Detonation to Decay: Time as a Measure of Thermodynamic Relaxation in a Quantum Fluid Bubble

We present a cosmological framework where the universe is modeled strictly as a thermodynamic event: a Quantum Fluid Bubble evolving from an initial high-energy detonation (nucleation) to a final state of thermal decay. Rejecting both biological analogies and the existence of fundamental time, we posit that "cosmic history" is nothing but the relaxation process of a highly excited superfluid vacuum seeking equilibrium. The "arrow of time" is identified as the gradient of energy dissipation. By utilizing the Logarithmic Schrödinger Equation (LogSE), we demonstrate that the logarithmic nonlinearity acts as a dissipative potential, converting the vacuum’s initial chemical potential into expansion and structure. In this view, "Time" is merely a bookkeeping parameter used by observers to quantify the depletion of the universe’s initial energy endowment. The universe does not travel through time; it expends energy to transition through phase space, moving inevitably from explosion to exhaustion.
