Despite much obeisance paid to black holes by ‘Standard Model’ cosmologists (not to mention Hollywood, e.g., the recent film “Interstellar,” alleged to have a basis in physics, but really pure science fiction), dissident physicists, led by Stephen Crothers, have re-examined the original analysis by Karl Schwarzschild which, due to an error by David Hilbert, has provided much of the basis for the alleged existence of black holes. This substantial body of work suggests black holes cannot exist, leading me to the logical conclusion that the densest stars possible are neutron stars (or perhaps, if such are possible, ‘quark’ stars) which have relatively small but ‘non-singular’ dimensions. Both the mass and “pulse” rate of many neutron stars (also known as pulsars) have been recorded. Examination of these data opens an avenue of speculation based on their angular momenta that perhaps could aid in the understanding of how ‘heavy” (relative to our sun) rotating stars might evolve into pulsars.
