If one instead postulates accretion as the decisive feature for the conversion, a consideration of neutron stars structure indicates a fairly narrow range for the onset of the critical density before the corresponding Chandrasekhar mass is achieved....

Relative mass is the mass of an atom or molecule relative to that of 1/12 of a carbon-12 atom. Under this scheme, a neutral hydrogen atom has a mass of 1. You can think of this as counting each proton or neutron as 1 and ignoring the masses of electrons because they are so small...

Understanding Relativity: The Effects of Relative Motion and Mass Well, relativity says whatever moves, it's volume shrinks and mass increases (as observed). So if i am traveling at 99% c with respect to a massive neutron star, do that star become a black hole for me?
