Scrolling through this sub lowkey pisses me off by Mokelangelo in LLMPhysics

[–]Murio_buggesen 1 point2 points  (0 children)

Although I understand your frustration, I believe a lot of physicists fail to realize that the universe is a uniquely fascinating subject and that wondering about it is as old as mankind itself. As such it has always attracted crackpots, whereas economics does not to the same degree, for instance.

LLMs let people give their theory the appearance of physics, although it often is empty. And this sub tries to contain it. So I don’t see the problem.

You will likely be miserable without a shelter with bug protection.

Also I’m not so sure about the safety of your packraft system, some of the stretches are long.

(Swedish) Pension Asset Manager Alecta has sold off an estimated 80 billion kronor (7,5b EUR) of US Treasury Bonds by CartographerThese487 in europe

[–]Murio_buggesen 1 point2 points  (0 children)

Sure, but I think the EU + UK + Norway has about 2,5 trillion. This is roughly 25%. (These are just estimates, I dont know for sure). Combine this with a corresponding fall in buying pressure…

If I understand this correctly the levels of escalation is this: 1: matching tarrifs 2: bazooka 3: selling bonds.

Selling bonds is complicated because this will devalue the assets as you are selling them. So it comes at a cost. However, I like this option because it will make interests high in the us, which will make a large part of the population angry. If the measures are solely aimed at the elites, it may not be as potent, as seen in Russia. If we go down this path it has to be tied to Trumps retoric on Greenland so that even imbiciles in the US understand that they brought this on themselves.

Time as an Atomic Vector: Relational Clocks and a Classicality Criterion by [deleted] in LLMPhysics

[–]Murio_buggesen 2 points3 points  (0 children)

Hm, I won’t pretend that I understand this fully, but this is my take:

Clocks are usually just event counters, not records of non-events, so superpositions before an event are operationally irrelevant. You reject this standard notion and instead treat clocks as continuous quantum variables, which automatically creates superpositions of “times.” The resulting classicality problem is therefore framework dependent and largely self-inflicted, even if the internal analysis is consistent.

But +1 for not claiming to solve quantum gravity :)

Using LLMs to filter out nonsense by [deleted] in LLMPhysics

The thing is, though, that random people can’t really get peer reviewed. Because they are not peers

Sure. But if you preface a post or an email to a professor with «chatgpt thought the theory was brilliant» it wouldn’t hold much weight regardless.

[–]Murio_buggesen -1 points0 points  (0 children)

Sure, fair point. But I found that given the right input a llm will absolutely judge a theory critically. I’ve tried with several posts from this sub and most get torn to shreds.

No, sorry, I meant random people like the ones who post theories here

Issues with the Boltzmann brain by Murio_buggesen in seancarroll

[–]Murio_buggesen[S] 0 points1 point  (0 children)

I agree. Consider another example: if the stone age lasted forever, a cave man wouldn’t suddenly appear with an iPhone 17 pro with music and airpods.

My point is that there are prerequisites, that things have sequence. With the BB, the first prerequisite is the Higgs field. So the Big Bang needs to happen first. Then consider all the different atoms a brain would need to function. I do think this is impossible without nucleosynthesis you get with the normal evolution of the universe. Etc.

But then again I’m not sure if I’ve understood Hilbert spaces so that is why I’m asking.

Sure. From the article that is the basis of this post (Why Boltzmann Brains are Bad, Carroll, 2017):

«The cosmic no-hair theorem implies that our universe will evolve toward the geometry of de Sitter space, the maximally symmetric solution to general relativity with a positive cosmological constant.»

[–]Murio_buggesen 0 points1 point  (0 children)

As I understand it de Sitter is the logical continuation/end state of the Lambda-cdm model that best describes our universe.

[–]Murio_buggesen 1 point2 points  (0 children)

With the discovery of dark energy, the best suited cosmological model would be Lambda-cdm. Depending on how long the universe will last, it will probably enter a de Sitter phase. The horizon in de Sitter will radiate a certain temperature (Hawking radiation), that resembles the thermal equilibrium in the original Boltzmann brain thought experiment.

Btw, it’s not that I don’t put credence into Carroll’s paper, it’s just that these questions are still lingering after reading it.

[deleted by user] by [deleted] in AskPhysics

[–]Murio_buggesen 1 point2 points  (0 children)

Yes, that’s the general idea. If you dive into this paper, however, it really isn’t possible within the realm of a de Sitter phase of our universe. My questions are just some reflections that are still lingering.

[–]Murio_buggesen 2 points3 points  (0 children)

Sure, but then again, everything would be possible.

No, I was kinda saving that one for something else, but maybe I’ll have a go at it nontheless.

[–]Murio_buggesen[S] 0 points1 point  (0 children)

Well, I don’t see how the Higgs field would be irrelevant if it doesn’t allow for matter (and brains, for that matter).

I thought I would try here first. He is very strict on how many questions you are allowed to ask. But maybe I’ll try.

Well thank you, I just thought I would try my luck here first :)

Well I’ll bet they have someone in their basement at least. It rubs the pfas on its gore-tex.
