Abstract
The recently discovery of a massive neutron star (PSR J1614-2230 of ) rules out the soft equation of states (EOSs) such as those included hyperons or kaon condensates at high densities, while the nuclear theory or the terrestrial laboratory data prefer a soft EOS. Here we propose one possible mechanism to allow that the observed massive neutron star can be supported by a soft EOS, that is, if the the gravitational constant varies at super strong field, a soft EOS can support the massive neutron stars.
