The problem with this POV is that "internally" we're only able to perceive certain things and, indeed, these things are ignorant to changes in spacetime configuration. This is exactly the power of this mathematical formulation.
So the Hole is a thought experiment where you construct two differently configured spacetimes, ones you might want to distinguish between, and then show that the perceptions of these two cannot differ in meaningful ways.
And then one should question as to whether or not they want to believe with any fervor that spacetime has a physical sense.
As I read that, I felt it was a bit too strong - isn't the issue whether spacetime have an independent physical sense? I went back to the article, and I see that it starts "What is space? What is time? Do they exist independently of the things and processes in them?" As the argument starts with a manifold of events, an answer of 'no' to the third question seems reasonable to me (though I realize, from experience, that that's probably because I haven't fully grasped the argument.)
As far as I can tell, the article doesn't indicate any particular problem with the 'no' answer.
In the argument in section 10.3.3, don't you have to accept the reality of K(t) in order to see a paradox?
It certainly wouldn't be the first time. Mostly, people just get used to it and live with "Nature is a perverse bastard."
I don't know how much I like the tone: I may be reading it with a bias. But hey, who knows where the next insight will come.
This sounds very interesting. Could you provide some examples?
I'm increasingly frustrated with this mindset. Yes, you don't have the time to read everything. The answer to this, in my estimation, is gear your reading toward information sources with higher density of quality. If, instead, you only read things with titles that summarize the content for you, you're limiting yourself to ideas which can be summarized in a 5- to 20-word blurb. These ideas and simple, and consequently, frequently wrong. Reality is often complicated and it's not possible to dumb it down into a "1 weird metaphysical argument that will make your brain grow 10 inches"-style clickbait headline.
I do think it's a courtesy to the reader to provide keywords in a title that make it easy to reference and that create an effective vocabulary for talking about the topic (which this title does). I don't think that authors have any responsibility to dumb down their titles into summaries for those who can't be arsed to hear them out.
As an aside: generally stuff published on Stanford's website is written by top professionals in various fields, which makes it a high-density source of good information.
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.
But, after reading (trying to, rather), I felt that the subject deserved some explaining for people who are unfamiliar with the topic as well. Hence my request for context.
I have never asked for anyone to dumb down anything, that's your frame of mind, please don't put that on me. In general, it seems you just tend to get frustrated by your own frustration. That might be a vicious circle, but I'm no part of it. Should I dumb this down for you? Or do you catch my drift.
