If a star's increasing density creates a singularity, which mechanism determines its observable event horizon?

💡 Explanation

The increased gravity causes the Schwarzschild radius warping of spacetime, because this defines the minimum radius for an object of that mass. Therefore, the event horizon appears; rather than nuclear reactions, this represents gravity overcoming all outward pressure.
