Gravity Can Explain the Collapse of the Wavefunction (Sabine Hossenfelder)

Oh no she has opinions god forbid.
detritus•1h ago
This doesn't suggest much of consequence, other than a vaguely-implied smear?

I've watched Hossenfelder's videos for years and whilst yes - she might perhaps be overly critical of a lot of things - I don't at all accept that she has weird, conspirational leanings.

Ad hominem attacks are not part of the scientific method
xoa•1h ago
>Ad hominem attacks are not part of the scientific method

Sure, but then again neither are arguments from authority. The thing is that we're not practicing the scientific method here on HN in general. Yes, from time to time on specific tech topics there have been cases we're posters have actually gone out right then and there and tried to replicate something or test an idea. But mostly we're a talk shop, not in a bad way but fact is most real world tests and experiments aren't conducive time-wise to the amount of time a typical discussion topic stays active. Actually practicing science for real is very expensive in both time and money and requires specific niche skills few possess. It's the work of a broad network of people over months, years an decades.

So we're left depending to a significant agree on evaluating authorities and what they're saying. Which is fun, but let's not confuse where we stand here. And while argument ad hominem is a fallacy against any stronger form of argument, it can be a perfectly logically reasonable argument against argument from authority. If someone says they are a licensed doctor practicing in a specific area of medicine, and that therefore the recommendation they're making about medicine in that area of expertise is worth paying more attention to, then it's very relevant whether they are telling the truth about their credentials or not, whether they seem to be reasonably sane, etc. We're left with proxy measures, but that can't be helped. We all have to economize and stand on each other's shoulders when it comes to advanced knowledge and technologies.

perching_aix•1h ago
That's true, it just also misses the point, like most invocations of ad hominem I come across.

People have lives outside of pursuing the scientific method. To decide to engage in that pursuit means taking away time and energy from other parts of life.

The argument here then is not that the paper is wrong because of who wrote it, but instead they insinuate that it probably is, and so it likely isn't even worth the time to try and evaluate whether it is.

This is a subtle but crucial difference, as this makes the core argument a speculation rather than a straight claim, let alone a scientific claim or refutation. And so for this, the identity of the author is a crucial bit, ad hominem cannot apply.

And this is if we make the ridiculous assumption that this was any more than just someone's informal opinion, like some sort of formal argument rather.

I guess you're pointing to: "Hossenfelder's more recent content has received criticism for her attacks on academic research[13][14] and for conspiracy theory-style portrayals of the physics community."?

She's been leaning very hard into clickbait and the shitty science journalist tactic of titles that obfuscate the lack of credibility of a claim, which is certainly unbecoming of a "real" scientist (mostly why I don't follow her content the way I do, say, PBS Space Time), I don't know if I'd say that's a conspiracy theory style portrayal though.

> I acknowledge help from ChatGPT 5 for literature research as well as checking this manuscript. I swear I actually wrote it myself

Swearing in a research paper is new thing to me. Might pass arxiv pre-published stage but definitely not a peer-reviewed one. But I doubt this will ever get published.

titanomachy•1h ago
Why not? Dr. Hossenfelder has published a bunch of papers in well-known physics journals. Is this one lower quality?
Aurornis•1h ago
This isn't a published paper nor is it associated with a journal. Given the atypically casual writing style I'm not sure it was ever intended for publishing in an academic journal or to be on par with her other papers.

Could someone explain this sentence?

> On the most trivial level, we can infer the mass and charge of a particle from its gravitational field.

How does gravity tell you the charge of a particle? I didn't even know it carries information about the sign of the charge, let alone the magnitude.

ur-whale•1h ago
Yeah, wondering the same thing. And there quite a lot of other statements in the paper presented as "obvious" that are IMO everything but.
antognini•1h ago
I'm guessing the idea is that in GR, the solution for a black hole with charge looks different from one without. So in principle you could infer the charge of a black hole based on the curvature of spacetime.
hammock•1h ago
And same logic applies to all masses, not only black holes. It’s just nearly impossible to calculate for anything besides a black hole, for a variety of reasons.

Also, the reference to “known links between the solutions of Yang-Mills theory and those of gravity” (Y-M equations describing charge and EM field) seems to speculatively imply that charge-related information is encoded in the geometry of spacetime, alongside gravitational effects

Qem•1h ago
> How does gravity tell you the charge of a particle?

Perhaps you can just assume a radius where the electron self-repulsion energy equals its own mass, by m = E/(c^2).

AnimalMuppet•1h ago
Even if you can, that doesn't tell you whether the self-repulsion is due to a positive charge repelling itself, or a negative one.
0xTJ•1h ago
It's important to note this is not a peer-reviewed publication, this is just some document that has been shared. While the author has a doctorate in theoretical physics, and has extensive experience in that field, their Wikipedia article also has the following line:

> Hossenfelder's more recent content has received criticism for her attacks on academic research[13][14] and for conspiracy theory-style portrayals of the physics community.

(The author recently had their affiliation end with the Ludwig Maximilian University of Munich, and is not happy about it.)

I don't know remotely enough to comment on the author's statements or research, or on the contents of this document, but I would advise caution on getting too excited over significant developments that haven't yet been peer reviewed.

In this paper she presents a novel, testable theory. It doesn’t have to be peer reviewed to be reliable. It has to be tested.
thot_experiment•1h ago
Sabine recently wrote a back of the cover testimonial for "The War on Science"[0] which is a collection of whiny essays by sex pests and racists[1]. It seems like she started off with some fairly reasonable criticisms of academia but over the past few years she's been pushed deeper and deeper into quack territory. AFAICT she's academically much less of a joke than the theory of everything VC guy, she's a real physicist. I'm curious to see if she's proposing something novel/meaningful/reasonable here, skimming the paper I can see it's above my pay grade.

I don't really have a point here, shitty people can do good things, humanity sure runs the gamut huh?

Your first quote criticising the book starts with "I didnt read this book".

Probably sums up what the book would be complaining about. No experience, didn't actually do any fact checking, makes claims we are supposed to just believe and call it science.

Second video doesnt seem to have any content from the book either.

Color me surprised.

dmbche•1h ago
So you dodn't watch the video but have things to say about it?

Glass houses heh?

And the book is a pile of trash

DarkmSparks•1h ago
Why should i watch a video about a book when the person explaining the book starts by explaining they never read it?

Thats Sabines whole position about the attack on science (Ive not read her book, but have watched her videos)

Science doesn't care if the person making nuclear bombs is a sex pest.

dmbche•58m ago
Why do you share your opinion without having examined the information available?

And : Second video

First video seemingly was just to show she did indeed write for that book

And wait - you've not read the book? But you are here defending it ? Want to take a stwp back and think about what you're doing here? And second video moght be a good start.

DarkmSparks•47m ago
I examined the information.

Im criticising the idea that scientific findings can be undermined with accusations of undesirable sexual preference.

They cant, to think they can and try to do so is stupidity of the highest order, I would have loked an actual review of the book, even though i didnt expect to find, nor did i find one in the sources.

The only reason I checked the sources was to confirm that stupidity continued in the sources and that they contained nothing of value.

dmbche•32m ago
You didnt read a book and didnt watch 2 videos, and now have to share your take with the world. Thank you dearly.
DarkmSparks•24m ago
So I did my bit

Could you clarify if you are saying there was anything other than a lot of logical falicies known as

https://en.wikipedia.org/wiki/Ad_hominem

Or if the only criticisms of the book are logical falicies.

dmbche•5m ago
Why would you ask me when you can watch the video itself instead of talking about it
DarkmSparks•1m ago
I have nade the claim the only criticisms of the book are logical fallacies.

Not 100% clear if you agree or disagree, but the way this works now, is short of any further criticism that isnt a logical fallacy, is just assune you agree with the book and have no valid criticism of it.

Thanks gor the recommendation, think I'll grab a copy and read it for myself.

thot_experiment•43m ago
And you didn't watch the 4 hour video detailing the contents of the book and the character of the authors lmao.
DarkmSparks•37m ago
I jumped through the 4 hour video and at no point did i find any reference to the content of the book. Just 100% ad hominems.

Anyone that has to resort to ad hominems already lost the argument.

Aurornis•1h ago
This is a strangely written paper. It reads more like a train of thought or YouTube video style that has been squished into the academic paper LaTeX template. All of the casual comments, informal writings, the ChatGPT acknowledgement, and sentences that start with "I..." feel out of place after reading a lot of academic papers in the same format. I suppose not surprising coming from someone who built their career on YouTube.

The author has become somewhat notorious in physics circles for groan-inducing takes. That's not to say everything she has produced is bad, because it's not, but she has taken a hard turn into audience capture and speaking over-confidently far out of her area of expertise. It will be interesting to see how the experts respond to this paper, if they do at all. Given the format I'm not sure it's actually designed to be submitted for publishing or if it's just formatted in academic paper style and uploaded to arXiv for some other reason. Note that virtually anyone can register for and upload a document to arXiv, so this being on arXiv.org doesn't imply anything specific.

MrGilbert•1h ago
> but she has taken a hard turn into audience capture and speaking over-confidently far out of her area of expertise.

Sounds like she is doing Youtube to earn some bucks off it, then? Usually, you'll stir up a controversy or make bold claims to create engagement, which in turn pleases "the algorithm".

Aurornis•1h ago
Kind of, but there's a difference between trying to stir up controversy by "just asking questions" as opposed to attacking the actual experts while overconfidently pushing competing theories, for example.

Lately she's been dabbling with soft support for well known grifters like Eric Weinstein, though last I heard she stopped short of actually endorsing his theories. I think there's just too many views to be had by courting that audience, so it becomes irresistible to engage with. The best thing a good physics communicator could do would be to completely ignore the well known physics grifters and focus on the quality content, but instead she has been leaning toward defensing Weinstein and others.

mrguyorama•1h ago
She makes really really good money. Angela Collier recently made a sad video about this.

Sabine makes a video with sponsorship included basically every day. With her subscription numbers, that's a LOT of money.

Basically, screaming that "They don't want you to hear THIS" is extremely profitable. She's a very well paid member of the anti-science ecosystem.

dylan604•1h ago
With that kind of description, I'm surprised she hasn't been tapped to join POTUS' administration.
ZebusJesus•1h ago
She isnt against science she is anti BS and calls out physics in general for well all of the BS. She is the one pointing out the problems of publish or perish and why it has resulted in a bunch of BS in academia and a bunch of scientists doing BS science just for the sake of writing papers. No new advancements, no new testable theories just a bunch of people making claims that can't be tested and screaming we need a larger collider.
Aurornis•18m ago
> she is anti BS

The problem with influencers like this is the way their fans get a giant blind spot for “BS” that comes from their chosen anti-BS person.

Sabine fans will always cite problems with academia pushing BS papers, but Sabine has herself been embroiled in a lot of arguably “BS” content for the sake of YouTube views and advertising dollars.

You have to acknowledge the irony of thinking that an ad-supported YouTuber pushing clickbait headlines is the lone person saving you from the scientists and their misaligned incentives.

the__alchemist•59m ago

cubefox•1h ago
This comment reads like you have a bot of an axe to grind.

> the ChatGPT acknowledgement

She acknowledged to have used it for literature research, not for writing the paper (she explicitly emphasizes she wrote it herself), which you didn't make clear. Many researchers today probably use it similarly for literature research (rather than just Google Scholar, Semantic Scholar, etc), and there is nothing wrong with that.

> I suppose not surprising coming from someone who built their career on YouTube.

Phrasing it like that seems misleading. She has a PhD and has worked in academia as a theoretical physicist for most of her career, she has published papers, and she has had a popular physics blog (with people like Peter Shor commenting) for much longer than her YouTube channel.

Aurornis•6m ago
> This comment reads like you have a bot of an axe to grind.

I actually opened the paper and started reading and I’m commenting on that. It’s frustrating that anything less than glowing positivity about YouTube influencers draws accusations of having an “axe to grind”. I don’t have any relationship to this person.

> She acknowledged to have used it for literature research,

Right, that’s the problem I was pointing out.

Using ChatGPT for physics research (even if it’s just summarizing papers, though it’s not clear what she meant) is well known to be fraught with hallucinations.

> she has published papers, and she has had a popular physics blog (with people like Peter Shor commenting) for much longer than her YouTube channel.

This is fairly misleading as it’s not hard to see her YouTube channel has found a far larger audience than her physics blog or her academic posts at institutes like the the Munich Center for Mathematical Philosophy.

In the very beginning of the paper she says she’s seeking a new affiliation.

GodelNumbering•1h ago
Unrelated to the paper, the most satisfying (would-be) explanation of gravity I ever learned was from AdS/CFT correspondence. Basically, it says that a Conformal Field Theory in D dimension is equivalent to a theory with gravity in D+1 dimensions. In other words, the physics that describe the 2D boundary of a anti-de Sitter space corresponds to theories that describe gravity inside that 3D space. This would click well with the holographic universe theory and entirely eliminate the problem of needing to explain gravity since it would be an emergent force

But alas, our universe is more like dS space (positive curvature), not AdS (negative curvature).

refulgentis•1h ago
This is a creative synthesis of a few familiar ideas (Penrose–Diosi intuition, time-dependent variational principles, and superdeterminism). But as a model it doesn’t hang together.

If you interpret this as a story, say “approximate quantum gravity lives on a matter x geometry product manifold; when the Schrödinger flow wants to leave that manifold, pick the closest product-like pointer state, and bias the lottery to match |a|^2”, it’s internally tidy. As a theory that is local, parameter-free, and predictive, it’s not there:

- the state-space restriction is inconsistent with known gravitational DOFs

- the “derivation” of Born’s rule is circular

- the collapse is enforced by global endpoint selection rather than local dynamics

- and the one quantitative lever (the “Penrose phase”) depends on gauge/UV-sensitive self-potentials

Interesting essay; not yet a model you can falsify without importing the very knobs it claims to avoid.

hammock•54m ago
Seems like a valid critique and I appreciate you offering it
