The event horizon does not expand until it consumes the neutron star, because the Schwarzchild radius is smaller than the radius of the neutron star. The neutron star collapses into the smaller black hole.
The matter cannot be considered neutrons anymore at that point, because it is too dense. Once neutron degeneracy pressure is overcome, they’re not individual neutrons anymore.
Once the black hole forms, the original matter never comes out again, even if it loses mass to Hawking radiation. The neutron star never comes back into view.
- zackmorris 5y agoHey you're probably right. I'm regretting what I wrote after rereading it. I'm just trying to find stepping stones to get from our sense of everyday reality to a mental model of what happens when a black hole forms. Like doing discovery on a big software project that someone else wrote. But it's all speculation and hearsay that has little to do with actual cosmology, because I'm a programmer not a physicist. This fringe stuff would have a better place in a book or sci fi. Too much streaming and social media, not enough study. Sorry if my words mislead anyone.
