Is There No End to This Pressure

Is the neutron star a dead end?

In the case of ordinary stars, remember, equilibrium is reached when the outward-directed forces of heat (from fusion reactions) are in balance with the inward-directed forces of gravity. Neutron stars, however, produce no new energy, simply radiating away the heat that is stored in them. They resist the crush of gravity not with the countervailing radiation pressure from fusion, but with neutrons so densely packed that they simply cannot be squeezed any more. Astronomers call these degenerate neutrons.

If this is the case, the neutron star is not so much in equilibrium as it is in stasis. A stalemate exists between the irresistable force of gravity and immovable objects in the form of a supremely dense ball of neutrons.

But if the force of gravity is sufficient, the collapse is apparently unstoppable.
