If you haven’t already done it, Pat (the Bunny) put all his stuff on archive and he’s far from the only one.

Looking at it from a quantum field perspective, pretty much. If the only interactions are through gravity then the underlying field’s evolution can’t be influenced by anything else, I have no real idea what the implications of that would be because we don’t have a QFT for gravity.

Got any recommendations for a music player?

I’ve paid for symfonium and love it tbh, it works really well, has great customizability and the offlining of favourited albums is so so nice. It has an internal download cache, but it can also export files to your downloads folder the way jellyfin does at the moment. My only gripe is that it’s not FOSS.

It’s always funny to watch people try to fix capitalism by doing more capitalism…

It’s embarrassing how often I confuse Austria for Australia when reading these articles…

For what it’s worth, I don’t really trust these ratings or put much value in them I just didn’t see where they said it was leftist. The UN in general seems more centre left than anything else, but I’m sure one could make a reasonable argument for any centre-ish leanings, I’m not actually taking a position here because I don’t care about the UN, beyond the fact that it sure isn’t leftist.

Am I looking at the wrong thing? Because it says it’s rated as centre left for me

Fuck q, kwire

That’s fair, I just like windows and that’s really all there is to it. I’ve had a few Linux installs in the past, but never really found an advantage to anything except compiling this one specific python library, but these days I can do that very easily running WSL, VS code SSH’d to my server or more recently a jupyter server that I can connect to from any device with a web browser.

Now macOS on the other hand, I absolutely despise. It was one of the first OS’s I learnt to use back in primary school, and now that I have to use it for work I have absolutely no nice things to say. Unintuitive, missing basic features and slow to navigate, and I can assure you that none of this is due to unfamiliarity…

Other than messing around with the beta for half an hour, I thankfully never had to use it.

Unpopular opinion that I have no justification for: I don’t mind windows 11 all that much

Thanks for this, that’s a fantastic way to phrase it.

No idea if I can reply to a deleted comment but I read the root comment totally wrong and just restated everything they said. My bad.

If that was the case, we would already have a quantum theory of gravity. The fact that “gravitons” (here I mean the particles of a second quantisation of GR) can interact with themselves makes the theory almost completely useless.

It’s technically possible to write down such a theory, but the only way to get results out of it is to first perform an infinite number of experiments.

Almost none of this applies in the case of something like loop quantum gravity, which I understand very little of but I don’t believe it’s possible to discuss it using the language of QFT like I have above.

I briefly worked in this area of physics, it’s complicated and depends on your definition of a particle and which quantum gravity model you’re talking about.

To simplify things you can just ask the same thing about non-quantum gravity. Why does gravity escape the black hole? The painfully mundane answer is that the black hole is gravity, it’s not escaping itself. Gravitational waves can’t be emitted from inside the black hole but that’s because those are a form of radiation and not the structure of spacetime.

This is specifically important because even quantum gravity (the kind with gravitons) still has this distinction. Particles belong to a field and are excitations of it, the gravitational field itself is not made of those particles. The force associated with that field is mediated by gravitons, but what that really means is complicated and honestly possibly just the result of a cool mathematical trick. It also comes with a bunch of crazy behaviour where you have particles that can break the laws of physics by just kinda doing it so quickly that nature blinks and misses it.

The point is, the quantum gravitational field is enough for the black hole to do its job when objects come by, gravitons don’t actually need to escape, though they are involved in complicated ways.

Now I’m wondering, surely someone has already made a language that’s designed to read like scripture?
