To be fair even our attempts at describing a technically possible but implausably simple version of a blackhole are essentially educated speculation. Although worth noting that black hole like objects did appear in fiction before they were discovered IRL.

You should say which appearance you have in mind. Year and author.

What do you mean? We understand them well enough that we can predict the gravitational waves of a black hole merger.

  IIRC, the biggest uncertainty is about the singularity. I don’t know if it’s still true, but my understanding was that the consensus is that it isn’t really a true point of infinitely dense mass. That is how our current models say it must be, but many assumed our current models are incomplete and that more accurate ones will show that it must have some volume. And given the extreme nature of them, any updates to our models might have some significant repercussions in other aspects of them too.

    So far, we haven’t seen a physical infinity in any part of the universe, so if our models produce a point of infinite anything, they’re probably wrong.
