What crucial physical state is maintained by the outward pressure generated from fusion balancing the inward crush of gravity?
Answer
Hydrostatic equilibrium.
The balance between the outward pressure created by energy release from fusion and the inward pull of the star's own gravity defines hydrostatic equilibrium, which sustains the star throughout its active lifetime.
