The Fastest Rotation at the Limit: A Period Floor for a Bounced Core
Year: 2026
Type: article
Abstract: A bounced core at the Aldred Limit cannot rotate faster than its mass-shedding limit, and because its density is fixed by the bound, that limit is a pure number of the framework: Omega_max = square root of (4 pi G rho_A/3), independent of the core's mass. On the neutron branch the corresponding period floor is 3.812e-24 s, a rotation frequency of 2.623e+23 Hz. On the electron branch the floor is 7.009e-21 s. No bounced core, of any mass, can spin with a period below its branch floor without shedding its equator, so the floor is a falsifiable consequence of the bound: a compact remnant demonstrated to have formed through a Limit bounce and rotating faster than 3.812e-24 s would contradict the bound on the neutron branch. The floor lies far below the fastest observed pulsar periods, so no current observation tests it; its value is as a sharp, permanent prediction that any future claimed detection of a bounced remnant must respect. Computed from stated assumptions, not measured.
