← ScienceWhich outcome occurs when a neutron star exceeds the Tolman–Oppenheimer–Volkoff limit?
A)Gravitational collapse to black hole✓
B)Onset of sustained nuclear fusion
C)Isotopic enrichment in heavy elements
D)Increased rate of radioactive decay
💡 Explanation
Gravitational collapse occurs because exceeding the TOV limit overcomes the neutron degeneracy pressure; this limit balances gravity against internal pressure generated via strong nuclear force. Therefore, black hole formation results rather than fusion because binding energy cannot counter intense gravity.
