- TL;DR Summary
- Time dilation means the collapse of the star's core stops after the event horizon is formed.

Here's my reasoning.

The event horizon is the point where the escape velocity becomes greater than the speed of light.

This results in the event horizon spacetime boundary having infinite time dilation.

So, that must mean that inside the boundary of the event horizon, time dilation must, again, be infinite.

So how would the collapsing core of a star keep collapsing? Due to infinite time dilation, the moment the event horizon forms, the collapse should stop, from the perspective of the rest of the universe. And indeed, before the event horizon forms, its rate of collapse should be observed to become slower and slower.

I thus argue no actual macroscopic black hole has a singularity, and if you added enough to spin to a black hole, you wouldn't get a naked singularity, but the core of a star that would promptly begin collapsing again and eventually form another event horizon.

(That is, unless the spin added to the event horizon transferred to the collapsing core, and the increased angular momentum stops the collapse)
