I find articles talking about dark matter/energy to be manipulative, here is why.

If you read the article itself you'll find that those names were invented as merely labels for the inconsistencies in how Universe behaved. So yes dark energy "exists" because inconsistency exists, and dark energy is merely a label name for that inconsistency, but nothing more. It's not given nor claimed by scientists that it is proven to actually exist as energy.

The manipulative part is that the words used in those labels bear their own meaning. "Matter" means something objectively detectable made of physical particles which you're able to interact with. But we don't actually know if that's the case.

What is more concerning is statements like this:

>Perhaps dark matter will never be detected, apart from its gravitational effects. Even so, that would not be an argument against its existence

Saying that if we cannot detect something does not mean that something does not exist its basically Russell's teapot claim. It is very concerning to see that in an article that claims to be scientific.

That's not manipulative. It's reality.

No it doesn't. And you don't get to decide that it does. But it does tell you something about the way "dark matter" is expected to behave based on observation. So does the "energy" in dark energy. These words are meaningful within the context, although like with all things in physics, words will always fail to convey a concept based on math, because they're meant as labels for things you are already informed about, not as a way to convey understanding.

Of course it is manipulative. Just like Tesla's "Full Self Driving" which is not fully self driving is manipulative. Words have meanings and contexts of their own, which was defined way before me, or the guy who coined Dark Matter, which is neither dark nor matter. Inventing context where black means white and claiming it's not confusing (and ultimately manipulative) is ridiculous.

Yeah, sorry, that's just not how it works. It's not misleading to call something that doesn't interact with electromagnetism, and thus light, "dark", and it's not misleading to call something that is acting like matter "matter". Whatever hangups you have about these words are really on you. It's not even close to misleading, and even when the short terms given to complex ideas are "misleading", it still doesn't make them manipulative. Things catch on, and once that happens, it isn't getting undone. That's not a conspiracy to manipulate you.

Anything with Dark Matter or Dark Energy is going to be clickbait. And so we see these piles of drivel almost daily here. :(

That's just dismissively reductive. Those "mere" inconsistencies were like half a dozen separate observations that differed from expected values by a pretty exact amount, noted by many people, across many decades. This wasn't some flippant, casual invention but the product of rigorous observation and calculation, challenged at every step by multiple other parties with alternate theories that, themselves, do not explain all of the aforementioned observations.

By your complaints, I offer you just don't understand the data.

I don't know why you put so much stress on it, I was not in any way arguing or diminishing inconsistencies, I realize how they are very important.

I was arguing dark matter and dark energy are confusing and ultimately manipulative terms. Claiming inconsistency exists is one thing, claiming dark matter* exists is another. It would be like naming it "dark overlords" and claiming dark overlords now exist, without repeating all the time that there are no actual overlords, it's just a label.

You wrote a big ol' screed baselessly attacking the article and the subject matter. Maybe don't do that?

Yes but everyone knows it's just a label, if they're too ignorant to realise then that's their bad, and tbh, it has literally zero bearing on everyone's day to day existence....for now anyway.

"apart from its gravitational effects" is a pretty huge thing to just ignore like that, bud.

sir bud dude, dark matter is a numerical correction to GR to match observed gravitation in galaxies, so he says "apart from" because it would be absurd to suggest that gravitational observations are direct evidence of dark matter

Literally all scientific models are made up to match observations. That's how the scientific method works.

yes, and so far no explanatory models for dark matter have been successful. Including dark matter as a parameter to match observed data is not the same thing.

dern_the_hermit t1_jc8lsj0 wrote

We don't have a model for dark matter. It is called "dark" because it is unknown. We are currently in the early stages of creating a model to explain observations, one good enough to make predictions. Several models, actually, of which dark matter - that is, "matter that only interacts gravitationally" - is the only candidate that can explain the widest range of observations.

the_JerrBear t1_jc8wdpc wrote

it's called dark matter because it only interacts gravitationally, not because we can't explain why it should be there. dark matter is not a bad model, it does explain observations well. we are not exactly in the early stages as far as that is concerned. nor are we in the early stages of attempting to explain what exactly that matter is, a lot of things have been ruled out that seemed promising at first. i would agree that the dark matter hypothesis is the most attractive solution available to us now, but the continuous failure of dark matter particle experiments, along with no unified theory to work from, makes it difficult to say that it is probably the right one. General relativity does not predict dark matter - we infer it from our observations. No experiment has been able to confirm hypotheses about the origins of dark matter, and there have been quite a few of them so far. It's good that we've come up with lots of ideas, and it can't hurt to keep trying, but we also know that general relativity and the standard model are not complete theories, so it seems unreasonable to me to argue that, because general relativity is nearly perfect, we shouldn't doubt dark matter.

No, the notion that it only interacts gravitationally came much later. Previously it was assumed that it might simply be... dark matter, regular old gas, dust, rocks, stellar remnants, black holes, etc. that were not luminous. Take a look at MACHOs and WIMPs for theories about "dark matter" being regular standard model stuff that simply wasn't glowing.

It wasn't until decades later that "it only interacts gravitationally" became the dominating notion, entirely based on the preponderance of observations indicating something like that.

the_JerrBear t1_jc8ysof wrote

Okay, I concede you that. It started out as "matter we can't see," and today a popular interpretation of that is that it doesn't interact with light at all. My mistake.

But, that also wasn't really my point.

Your point was some crude dismissal of dark matter based on what seems to be a gross misunderstanding you have. Sorry for correcting your misunderstanding. It must hurt your feelings, being corrected.

at no point have i dismissed dark matter, i have only presented arguments against the evangelization of dark matter, which this article supports. you argued beside the point, and have now volunteered yourself to exit the conversation.

the_JerrBear t1_jcfency wrote

if you interpreted that as an outright dismissal that dark matter is correct, then again, you have entirely missed the point... Saying that "not having evidence doesn't mean it doesn't exist" is not a strong argument for dark matter, or a strong argument against alternatives. It's pleading, and doesn't really imply anything meaningful. I hear it when people ask for proof that god exists.

I don't understand why you insist that I have claimed dark matter is incorrect, maybe I am failing to communicate my point properly, but that definitely is not it at all. I would appreciate it if you took some of your valuable time to respond to literally anything else that I have actually said, thanks

That doesn't mean any scientific model is correct. I can make a model with gravitons to explain gravity, it doesn't mean they exist. Same with dark matter.

That's false. I can imagine that electrons are little conscious demons with mass of electron and charge of electron. It will explain things right, but it will contain unnecessary and unproven assumptions.

The names were invented for REAL observations. They observed things happening that could not be explained without extra mass or energy. The names are made up but the phenomena is real.

All names are made up by the way.

Of course there are ways to explain observations without extra exotic mass or energy, there are several of them including as simple ones as "we've just miscalculated the actual mass of the gas in the universe" to differences in constants through time and/or space. Possibility of different explanations is the whole point of this thread.

Sure, extra mass from exotic particles was the easiest knee-jerk explanation to additional gravitational pull, but it does not make it the right explanation, and decades later we still have no idea if that exotic matter/energy is even there, yet the name continues to confusingly assume it is, and articles that say "dark matter is real" are inherently confusing because they can mean "exotic unknown matter is real" or "observations discrepancies we labeled 'dark matter' are real". And authors know it but still do it for clicks.
