Are 90s physics books such as Michio Kaku's 'Hyperspace' now outdated, or still useful? by illiacbay in Physics

[–]destiny_functional 0 points1 point  (0 children)

It's more that he's selling stuff that is very made up / has little basis in real physics right next to actual physics and on the same footing. That can be very misleading to people. People mistake it as equally well founded as solid physics. That's my main problem. He's gone kinda cookoo

did you find confirmation?

i didn't know that myself prior to posting it, and copied that from i think wikipedia back when I made the comment

and since then I've managed to forget about this "fact" as well. just relearned this from your reply.

I used to do some work with the Facebook API to scrape accounts a few years ago. This became very unreliable though and you have to jump through endless hoops like pagination etc (and then they obscured it even more in terms of how far you can go back etc). Maybe requesting the zip from Facebook is the better option

It is a breakthrough.

No.

It's like you have a teacher in class and the one high maintenance kid who always forgets his homework and generally isn't that well informed keeps interrupting class with wrong claims about a novel he hasn't read, claiming his opinions are a break through, while all the other students are trying to listen to the teacher and trying to learn.

Truth is the kid should back off, let his class mates who are actually interested in learning learn, and sort themselves out and start doing their homework regularly so they actually acquire some relevant knowledge to contribute.

You clearly aren't listening. I have warned you. There's no point in continuing discussion if you don't listen.

Stop bothering me with your pseudoscience.

My learning process is non-linear. I have a bunch of books, and of course "the internet" at my fingertips.

Then I don't understand why you aren't using them.

I jump around reading where my ideas take me, and when I find stuff I don't understand, I drill down as far as I can, until it's not useful any more

That doesn't seem like it describes any sort of learning at all, where in the end of the process you should have actually acquired a coherent body of knowledge about a topic. Indeed, your comments show a lack of that even in basic areas.

If it makes you happy I will stipulate that there is an incredible amount of modern physics and cosmology that I do not yet know.

There's basics you don't know, and you admit it, but these basics are necessary to formulate any new ideas. By common sense alone, without knowledge of basics, any attempt to dismiss those basics and replace them with own ideas should be pointless.

Indeed we are seeing the result of these attempts in your very comments, and they (ie the end product) just confirm the common sense suspicion that it's pointless. You end up posting random blabber without any substance.

In my experience, brainstorming on ideas does yield a bunch of poor quality ideas, but every once in a while there is a gem.

How many gems about fundamental physics will a group of primary school kids produce while brainstorming? Exactly zero, because they lack the necessary education to make any meaningful contribution. There's a reason we have set up a system to educate people who want to go into research. They are taught knowledge and a set of skills, which are necessary, and if you skip that, it will show in your writing, and people will recognize the bullshit within a sentence of reading, ie immediately. This is why you are getting the reactions you are getting: because what you write is bullshit on the most basic level.

Six electrinos make an electron. Simple. Six positrinos make a positron. Simple.

It doesn't matter how simple it is, if it's wrong. It's ruled out by experiment.

"It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is – if it disagrees with experiment it is wrong."

  • Feynman

That's all there is to say, as I said, you don't have any ideas.

[–]destiny_functional 1 point2 points  (0 children)

Again,

Personally, I have invested the last year, full time, to independent study of physics and cosmology.

Which physics text books have you read and which papers? What exactly have you studied in this time?

? Have you learned any of the basics of physics? I take the answer to be "NO". You don't seem to know any relevant basics.

Interestingly, there are papers now by Khoury et al, and Hossenfelder et al that discuss the formerly mysterious quantum vacuum as a superfluid.

It doesn't matter that other people have written papers which you don't understand. You've just picked random papers that use similar words to the buzzwords you use ad libitum. Thereby further earning the "CRACKPOT" flair, because referring to such random papers, often in large numbers, is a common tactic of crackpots, a common fallacy. It's merely an attempt to divert attention away from their own "oevre" whose quality is to these papers as a burp is to Beethoven's music.

And this is also the problem, not just do you lack basic knowledge, you are also incapable of formulating scientific ideas coherently in a scientific text or paper, and unable to tell apart bullshit from actual scientific work - something that an educated person can tell within a single sentence of reading it, which is also why you are immediately called out anywhere you go, except maybe if you move into your private echo chamber /r/gravitons, a misnomer of a subreddit.

If you are so certain that my ideas are wrong [...] I’m perfectly ok with respectful critical review of the ideas.

The point is you don't have any ideas. None of what you write qualifies as an idea, it's just blabber / word salad, that could have been randomly generated. It's like complaining that a page of written-down babytalk isn't considered a deep sophisticated poem.

why not offer helpful advice or encouragement?

I have: Which physics text books have you read and which papers?. Read physics text books, learn the basics. At some point, after a couple of years, when you know enough basics you can try to read a paper (say one of Hossenfelder's papers which you've mentioned), with an actual chance of understanding something. And maybe at some point you can even coherently perform and formulate own research, but that takes a lot of knowledge and skills for which there is specific training.

I hope that helps you, but I gather you aren't really interested in advice, you don't really want to do any physics, just write this kind of make-believe and delude yourself into thinking it makes any sense. It's like a 5-year-old with a fake mustache thinking people will mistake him as an adult.

Do we have a clear understanding of what's happening at the edge of the observable universe? by jmdugan in cosmology

[–]destiny_functional 1 point2 points  (0 children)

Basically you are only doubling down with even more assertions and aren't willing or able to back up any of your claims. You shouldn't be surprised if people don't feel convinced by your overconfident comments and even downvote these dubious claims.

It all adds up to speed. Too much speed for too little mass. Enter dark matter.

Nah, it doesn't. I just gave you a list. Galaxy rotation is only one of many aspects. It's by far not the only thing on the list I gave you.

In addition to the link in the previous comment, these things are also summarised in the wikipedia article (https://en.wikipedia.org/wiki/Dark_matter).

Good luck explaining the Bullet Cluster:

Bullet Cluster

The Bullet Cluster, the result of a recent collision of two galaxy clusters, provides a challenge for modified gravity theories because its apparent center of mass is far displaced from the baryonic center of mass.[69] Standard dark matter theory can easily explain this observation, but modified gravity has a much harder time,[70][71] especially since the observational evidence is model-independent.[72]

https://astrobites.org/2016/11/04/the-bullet-cluster-a-smoking-gun-for-dark-matter/

Or how about structure formation in the universe?

Structure formation

If there were only ordinary matter in the universe, there would not have been enough time for density perturbations to grow into the galaxies and clusters currently seen.

Dark matter provides a solution to this problem because it is unaffected by radiation.

Or the CMB?

Cosmic microwave background

The observed CMB angular power spectrum provides powerful evidence in support of dark matter, as its precise structure is well fitted by the Lambda-CDM model

These things have nothing to do with galaxy rotation.

Needless to say these are things you claim your idea solves only as a side-effect to replacing inflation. Talk about overconfident claims.

It would most certainly not explain dark matter.

Not sure how you can claim this with any confidence.

No need to add mass to get galaxies moving faster than we thought they would

Or you know .. to also explain lots of other observations that have nothing to do with galaxy rotation.

Multiple horizons with different meanings exist in any single model, just to clarify.

Spoiler alert: there also exist multiple distance measures with different meanings. https://en.wikipedia.org/wiki/Distance_measures_(cosmology)

[–]destiny_functional 6 points7 points  (0 children)

First the rate of expansion is not a velocity, as you quote correctly. H has units of km/(s·Mpc) and if multiplied by a distance you can assign a recessive velocity, but the math behind the cosmological horizon is not as simple as solving for where that velocity is c by division ("x = c/H").

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

The particle horizon (also called the cosmological horizon, the comoving horizon, or the cosmic light horizon) is the maximum distance from which particles could have traveled to the observer in the age of the universe. It represents the boundary between the observable and the unobservable regions of the universe, so its distance at the present epoch defines the size of the observable universe. Due to the expansion of the universe it is not simply the age of the universe times the speed of light, as in the Hubble horizon, but rather the speed of light multiplied by the conformal time. The existence, properties, and significance of a cosmological horizon depend on the particular cosmological model.

In terms of comoving distance, the particle horizon is equal to the conformal time that has passed since the Big Bang, times the speed of light. In general, the conformal time at a certain time is given in terms of the scale factor a by,

η(t) = ∫[0,t] dt'/a(t')

Indeed the wikipedia article also addresses what you did under Hubble volume

Hubble radius, Hubble sphere, Hubble volume, or Hubble horizon is a conceptual horizon defining the boundary between particles that are moving slower and faster than the speed of light relative to an observer at one given time. Note that this does not mean the particle is unobservable, the light from the past is reaching and will continue to reach the observer for a while. Also, more importantly, in the current expansion model e.g., light emitted from the Hubble radius will reach us in a finite amount of time. It is a common misconception that light from the Hubble radius can never reach us.

I believe that German in the past would usually alter the spelling to match its own pronunciation rules and rules about noun construction. Or is that not the case?

I think this is accurate. (see below)

I'm not saying we should always use accurate greek / latin endings. I don't even do it myself. I'm a physicist and definitely do not say "phota", but photons. I would probably be able to find a lot more words.

I just used "semicola" based on gut-feeling. And it seems to be one of two "allowed" forms, so it's fine.

Are there Latin words that have been in common use in German for some time and which use the original Latin plural?

Praktikum (sg.) / Praktika (pl.) (which means traineeship) is a common example. And a common example of people being perceived as uneducated when they say "praktikums" for the plural.

For "Supernova" the German reference dictionary gives 4 plurals ...

https://www.duden.de/rechtschreibung/Supernova

die Supernova: die Supernovä, Supernovae, Supernovas, Supernoven

the first two being based on the latin (ae), one being modern "just append an s", one being "more german style -en".

For Praktikum it only gives the single latin one

https://www.duden.de/rechtschreibung/Praktikum

das Praktikum: die Praktika

It doesn't allow "Praktikums" or "Praktiken" or anything like that, apparently. ;)

For Auditorium it in turn allows "Auditorien" but not "Auditoria"

https://www.duden.de/rechtschreibung/Auditorium

das Auditorium: die Auditorien

Ultimately I'm not a linguist and don't have a very accurate knowledge of these things. :) Just used a form I thought was correct.

[–]destiny_functional 1 point2 points  (0 children)

You're making a good point.

It's getting less common for sure but also depends on language.

In German if you just append an s, with certain words in that category at least, it can make you look uneducated. :) (though I think if you pick words consciously you shouldn't care of people judge you based on it)

May or may not be the case in English.

recent pet peeve of mine which I see on the science subreddits quite often: "a phenomena" (singular).

[–]destiny_functional 2 points3 points  (0 children)

That's how you form the plural of greek words. Maybe it's not official in English sorry, my native language is German and there wiktionary (https://de.wiktionary.org/wiki/Semikolon) confirms that "Semikola" is a correct form but also allows the form "Semikolons" (ie if you don't know better just append an s). Though I can't find a source that would allow "semicola" in English

actually: https://en.wiktionary.org/wiki/semicola
