A study has shown that if the mass of a neutron star exceeds 3.22 times the mass of the sun, the neutron cannot compete with its own gravity, and neutron collapse occurs. Which of the following points strongly support the above conclusions:. ['There are black holes in the universe that are infinitely more massive than neutron stars.', 'There are many mysterious stars in the universe that are 3.22 times denser than neutron stars.', 'Gravity caused by no matter in nature that can support 3.22 times the mass of the sun.', 'Collapse is one of the ways that a massive neutron star brings a new equilibrium to the interior.']
