What physical state is achieved when a newly ignited star's energy output balances the inward gravitational pull?
Answer
Hydrostatic equilibrium
Hydrostatic equilibrium signifies that the star has stabilized; the outward pressure generated by the ongoing hydrogen fusion precisely counteracts the inward crushing force of its own gravity, marking its official entry onto the main sequence.
