I have seen articles about the Milky Way's "gentle giant" black hole. For example:
Both of these articles say the black hole is not eating very much matter, which is the only clue I have from the articles.
A similar phrase, "gentle singularity," is used in the movie Interstellar. There has been some discussion about that, in which the consensus seems to be that the size of a supermassive black hole reduces the tidal forces at the event horizon, such that a falling entity would not be spaghettified. (I acknowledge that a movie quote is far from authoritative.)
So I have two hints at a definition of "gentle giant" black hole:
- A black hole that consumes little matter.
- A supermassive black hole whose tidal forces will not cause spaghettification.
Is either of these correct? If not, is there an authoritative definition of a "gentle giant" black hole?
