Fix typo and a little grammar
What is a black hole island?
I have stumbled at [this article][1] about [black hole islands](https://arxiv.org/search/?query=black+hole+island&searchtype=abstract&source=header).It is unclear to me, what is meant.* Does it claim that the black hole's interior does not contribute the BH mass and in fact situated outside of the event horizon?* Does the BH interrior represent all of the matter outside of the event horizon or only the Hawking radiation?* Is the interior of different black holes get swapped?- [1]: https://www.scientificamerican.com/article/how-the-inside-of-a-black-hole-is-secretly-on-the-outside/

- * Does the BH's interior represent all of the matter outside of the event horizon or only the Hawking radiation?
- * Is the interior of different black holes getting swapped?
