I may have misunderstood voidz's question but I don't think he's asking for a dumbed-down tldr or something to be spoonfed to him.
The keyword I read in his question was "context". In other words, was there another event or news article that prompted the OP to submit "Hole Argument" and for multiple people to vote on it enough to have it show up on the HN front page?
For example, on the front page there's a post "Python is the new BASIC"... it's an old 2008 article... why is it there?!? I think many of us can guess that its submission was possibly triggered by the other article "Guido on Python" from EuroCon 2015". Reverse engineering the context is a little easier in that case.
The "Hole Argument" is interesting, but there are thousands of interesting physics articles... so maybe there's another trigger that prompted its submission. E.g. a recent discovery at Hadron Collider, or one of the authors recently passed away, etc.
Of course, the article's submission may be purely random in which case there is no context. The submitter (infinity) can clarify that for the voidz.
