As to it being a source of dark matter, the idea that black holes and other compact objects are dark matter is encapsulated in the MACHO (MAssive Compact Halo Object) theory. It is extremely unlikely to be correct, because observations largely rule this out. Black holes warp spacetime around them and result in detectable phenomena as a result of gravitational lensing. It would appear that such lensing is not common enough to allow for black holes in sufficient quantity to explain dark matter.

I don’t think you meant dense though, I think you meant mass, because that’s sort of how your post seems to be phrased. The answer then is that it is a minute fraction of the mass of the galaxy. Sag A* is about 4 million solar masses, and the Milky Way has 250 billion stars, many of which are far more massive than Sol. Even ignoring other objects like stellar remnants and nebulae, the mass of the central black hole is negligable on the scale of the whole galaxy.

So we have a HuffPo article, an article from MarriPedia (a religious site) and an abstract from the Sociology and Religion department of The Association of Sociolgy and Religion. Three famously unbiased, data-driven outlets (/s) which even then, only tangentially support part of your point, and then only through the loosest of correlations.

Quantity is no substitute for quality.

I don’t think it’s so much a carried or implied assumption as his central thesis, and his justification down the thread is a page of more claims and anecdotes. Call me cynical, but I don’t think there is any “there” there.

So while Tesla as a healthy company without crushing impending debt would almost certainly be better off without him, Tesla as it is only really exits because of his presence. Long term they have to actually make a lot of money and stop hemorrhaging money, and get out of their death spiral. Short term the only way to do that is sell expensive stock, and that stock is expensive because of the cult of Musk.

I’m fairly sure that history will almost instantly forget them, because they exist to be disposable, to be replaced, and as interest and attention moves on their “mark” on history will be exceedingly shallow. Maybe that’s the difference between this constructed “reality” and... reality. Something real can be lasting, while this cotton candy version of reality only seems substantial from a certain angle, for a little while. It’s a kind of shallow “reality” for shallow people with minuscule attention spans.

It seems like the equivalent of someone preaching homeopathy and saying that doctors who don’t like it are just protecting their jobs because if homeopathy takes off, they’re ruined. Only it’s somehow even more poorly presented in this article. You know the routine, pharmaceutical companies are hiding the miracle cure for cancer to make money on treatments, but... with crypto.

How did it come to this?!

As I said, beyond that suit, i.e. the suits he’s facing over the tweets. And the DOJ investigation.

Tesla though, is in a real death spiral with their debt.

That’s going to be muuuuuch harder to correct, given that they’re going to have sell a load of discounted stock just to keep afloat in 2019.

Also...

Spider goat, spider goat, doing whatever a spider goat does. Is it a spider? No it’s a goat. Spider goat. Spider goat.

Nature can only get us so far with the current state of the art of materials science.

You have to admit though, based on comments all over any story about Tesla here at least, that it works as a bogeyman. The only other fiction that’s more powerful is that Musk does everything he does to send humanity to Mars, save the world, etc. Musk has a true talent for figuring out what his target audience wants to believe, and then selling it to them at a premium. Smart, technically minded people (key early adopters of Tesla) are desperate for a way to keep humanity going in the face of climate change, possible impact events, and so on. Musk more or less frames his rather mundane personal aggrandizement and money-making endeavors as lynchpins in just those areas. He helps to convince people who want to believe, that they can help save the world not through anything like sacrifice, but by buying stock or a luxury car!

They eat it up, and are enraged at people who scoff, and no one scoffs harder than someone who puts their money on a bet that the stock is overvalued. As a result the short is already a subject of hate, and perfect to pin all of the evils of the world on. It perpetuates a classic tribal narrative and dresses it up in just enough pseudo intellectual finery to convince a target audience which already wants to believe. As a bonus that audience thinks it’s too smart to be fooled that way, and above tribalism, making it easier to sell the story and harder for them to admit what they’ve fallen for.

Look at some of these comments, and you see the evidence of just what I’m talking about!

The law says a lot of things. I'm ok with short sellers losing their shirts regardless.

I also take the long view; Elon is instrumental to the long-term outcome for Tesla, our species, and our planet.

—

Because he made short sellers look like idiots? I think not. I just bought more.

SEC suing Elon Musk is , quite frankly one of the most abhorrent actions a US govt agency can ever do against genuine American Entrepreneurship and American innovative spirit. There is not a single human being on the planet who comes close to Elon Musk when it comes to big , bold innovation and tech entrepreneurship who is putting his heart and soul into leading the human race into the future.

—

you can’t disrupt or otherwise show up all of these players: the us/eu/russian/chinese space industries (and by extension the governments of china and russia), the oil industries of russia/saudi/usa, the major auto manufacturers, power companies, professional car and truck drivers, and the us dealership association (what am i forgetting), all of whom are politically very well connected, and some of whom have their hordes of paid shill internet commenters, and upvoting/downvoting bot nets (not that that would ever happen on hn (and if it would it’s against hn rules to suggest it)) and expect not to get trounced. elon might have fucked up by sending that tweet, but the response here, on reddit, and by the gov’t is way out of proportion, esp considering everything positive that this man has accomplished and is currently working on.

—

He didn’t screw anyone over. Wall street gamblers lost money, and our culture coddles Wall Street bros like helpless babies. Traders who lost money wouldn’t have had the stock to trade without Elon in the first place!

—

The entire world will lose if Elon is forced out. He’s the biggest fighter for climate change and space travel in modern history, greater than Al Gore in marketing and execution, greater than Buzz Aldrin, Tyson, and cosmos. I’d much rather have an honest relatable Elon Musk than a suit. I’d rather have creativity than suffocating structure.

—

The subtext is that Elon intentionally bumped the stock price to screw over short sellers like Jim Chanos. But the rationale behind 10b5 is to protect investors from fraud. Right, we are not concerned with protecting short-sellers who spend all day on twitter making up negative stories about their targets.

The battery and solar operations side of TSLA are critical to spaceX's mission to Mars. Can't have a martian colony without being able to harvest and store energy. Additionally the CV being done at Tesla could prove critical in automating prefabrication of living spaces and life support infrastructure. Can't be doing anything like that remote controlled with 8 min latency.

—

What a joke, there are plenty of scumbag and criminal leaders of corporations and this is the guy who doesn't walk. It'll be a sad day for the world if this guy goes to jail.

I know where Elon comes from, what missions and goals he has stated for years now, and what he is trying to accomplish. I promise you, Elon legitimately thought there would be an opportunity to go private again. He's said he wanted to do so in the past, and even has said they never wanted to go public, but were left with no choice. I don't think any part of Elon was trying to commit fraud or security manipulation. He made a mistake, we all do. He said something that should not have been said at that given point of time. I'm sure he was excited. He even said he typed that tweet in the car after leaving SpaceX.

Plus he clearly lives for it, and when anyone makes even reasonable points against him, he loses his mind on a Twitter. That is after all what happened with “pedo guy” re the Thai cave rescue. Musk made an ass of himself by trying to inject himself into a potential tragedy for some PR and a man who actually helped to save the day called him on it.

I’m also not sure that it would be hard to idolize a group, people manage it for sports teams. Maybe if Musk put the effort he spends into grooming his ego into promoting his team he wouldn’t need to be the center of a cult of e-sychophants.

Merge my code! It’s great!

No.

Aaaand scene.

Hell, that “no” could even have been a silent stare, or a grunt and it would have worked. Sadly much of the World finds that crosses the line fopekm taciturn and direct, into either rudeness or lack of communication. Dressing things up with layers of words, while tedious, is also the basic way many cultures keep arguments from turning into murders. North America (and the UK and some other parts) probably do take it a bit far. Not as far as Japan, but still, too far.

All of which is to say, yes it’s probably cultural, but it’s also a matter of people who are invested in something missing the obvious. Sometimes you really have to drive a point home, and my general recommendation was that it’s better to do so directly and civilly, rather than rudely.

The end is “nothing more to talk about,” and then you stop replying. As to time and energy, if you’re so depleted than an extra few sentences will materially impact you, then that is a problem. Healthy humans won’t be exhausted by expressing themselves in a half paragraph rather than a muttered “crap”.

Some people are persistent and will blame you for explaining badly when they don't understand. These discussions never end; usually not even after things got labelled as crap.

So don’t call it crap, just clearly state that you’re not interested anymore and hit ignore. The rest is their problem, not yours, and you’ll gain a reputation for being forthright and firm rather than hysterical.

Personally, I just stop responding after the technical arguments have been exchanged. There is no point in repeating what was ignored already, no point in ELI5, no point to using swear words, silence is what works best.

Amen brother.

By the way, if you told me "I understand your passion, but...", I'd be angry beyond belief. That's the way you talk to children, and even my mother is no longer allowed to talk to me like that. I consider that a stronger insult than my code being called crap. Which probably shows that shutting up in time is the best response.

The person in the example was acting like a child, and deserved to be treated (politely) like one. Either way though, my particular wording was just off-the-cuff and only an example.

The end. No need to call it crap, no need to burn a bridge.

Did you read the methods section? They did no such thing, and I’m curious as to why you claim that they did. At least have the intellectual honesty to yourself if no one else, to skim the study before posting nonsense.

Hundreds of late-stage pupae were removed from brood frames and allowed to emerge under sterile conditions in laboratory. (Experiment A) NEWs were exposed to bee gut homogenate for 5 d, then hand fed 1 mM glyphosate or sterile sugar syrup on 2 alternate days. Fifteen bees from each group were sampled 2 d after the last hand feeding. DNA was extracted from dissected guts, used as template for qPCR analyses, and submitted for Illumina sequencing at the GSAF, UT Austin. (Experiment B) NEWs were exposed to a bee gut homogenate or sterile sucrose syrup. Each group was divided into two subgroups and treated with 0.1 mM glyphosate or sterile sucrose syrup for 5 d. After that, half of the subgroups was exposed to the opportunistic pathogen S. marcescens kz19, whereas the other half was used as controls. Bees were exposed to similar amounts of glyphosate (∼1.7 µg) in experiments A and B.

NEWs were hand fed 5 µL sucrose syrup containing ∼105 cells of S. alvi wkB2 or wkB339 or sterile sucrose syrup as control.

Hand fed does not equal “immersed in for 5 minutes” by any means.

In Vitro Experiments with Bee Gut Bacterial Strains. Honey bee and bumble bee gut bacterial strains (SI Appendix, Table S1) were cultured in InsectaGro or MRS broth in the presence or absence of 10 mM glyphosate in a 96-well plate and incubated in a plate reader at 35 °C and 5% CO2 for 48 h. Optical density was measured at 600 nm every 6 h. Experiments were performed in triplicate.

Plasmid Construction and Transformation. The aroA, yhhS, and tetC genes from various bacterial strains were PCR amplified and cloned into the arabinose-inducible pBAD30 vector (45) by Gibson assembly (46) and then used to transform E. coli strain BW25113 or a derivative lacking the aroA gene by electroporation. Primer sequences are listed in SI Appendix, Table S2.

Growth Rate Analysis of Transformed E. coli. Transformed E. coli cells were cultured in duplicate in 24-well plates containing M9 minimal medium (47) with appropriate antibiotics, varying concentrations of glyphosate, and varying concentrations of arabinose. The plates were incubated in a plate reader at 37 °C for 24–96 h. Optical density was measured at 600 nm every hour.

All in all it’s a diverse and comprehensive methodology which still needs to be replicated, but not dismissed offhand by you.

Now, can we get back to the topic at hand without these diversions? You were claiming that the “circus” of the UK being outraged by the use of a chemical weapon to attempt to murder two people on their soil, and the incidental killing of a third and injury of a fourth (both civilians) was a “circus” I think. I’m still interested to your non-diversionary response to my take on why that would legitimately anger not just the government of the UK, but anger and terrify its people.
