  We present a modification of our previous model for the mechanisms underlying
the glitch phenomena in pulsars and young neutron stars. Accordingly, pulsars
are born with embryonic cores comprising of purely incompressible
superconducting gluon-quark superfluid (henceforth SuSu-cores). As the ambient
medium cools and spins down due to emission of magnetic dipole radiation, the
mass and size of SuSu-cores are set to grow discretely with time, in accordance
with the Onsager-Feynmann analysis of superfluidity. Presently, we propose that
the spacetime embedding glitching pulsars is dynamical and of bimetric nature:
inside SuSu-cores the spacetime must be flat, whereas the surrounding region,
where the matter is compressible and dissipative, the spacetime is
Schwarzschild. It is further proposed that the topological change of spacetime
is derived by the strong nuclear force, whose operating length scales is found
to increase with time to reach O(1) cm at the end of the luminous lifetimes of
pulsars. The model presented here model is in line with the recent radio and GW
observations of pulsars and NSs.
