  "abstract": "We show that in Non-Equilibrium Dynamics (NED), the universe is currently decelerat-\n\ning, and derive the deceleration parameter\n\nq0 =\n\n1\n\n2\n\n.\n\nThis is a direct consequence of the exact cosmic equation\n\nM′\n\nv + M a = F0\n\nwith the exact mass scaling M &prop; R(R − ℓp). Solving for the acceleration,\n\na =\n\nF0 − M′R˙\n\nM\n\n,\n\nand using the matter-dominated expansion R &prop; t\n\n2/3\n\n, we find\n\nM′R˙\n\nF0\n\n=\n\n4\n\n3\n\n> 1.\n\nTherefore,\n\na = −\n\nF0\n\n3M\n\n< 0,\n\nand the deceleration parameter is\n\nq0 = −\n\nRR&uml;\n\nR˙ 2\n\n=\n\n1\n\n2\n\n.\n\nThe physical cause is mass growth: it consumes 4/3 of the Planck-scale repulsive force,\n\nleaving −1/3 for acceleration. This result requires no dark energy. It is a falsifiable prediction\n\nin direct conflict with the standard interpretation of Type Ia supernovae, CMB, and BAO,\n\nwhich indicate q0 &asymp; −0.55. The prediction q0 = +1/2 provides a decisive test of NED.",
