Can Rotation Make Spacetime Grains Last? Internal Angular Momentum and Longevity of Source-Free Enchan Grains

This work studies whether internal rotation changes the longevity of source-free localized excitations in the reduced Enchan local time-rate field. The frozen scalar dynamics are S_tt = div[mu(D) grad S] - S with D = |grad S| and mu(D) = 1/(1 + D^(3/2)); no continuing external torque, centrifugal force, primitive matter source, or added rotational potential is used during the reported evolutions. Stage A supplies the non-rotating source-free baseline. Stage B1 initializes rotating phase-space states at omega = 4, 8, and 12 and evolves the extended runs to dimensionless time t = 100. Over 80
