EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
Dark matter. Sounds like a catch all designed to make a math model work properly.
You’re not wrong. According to the current scientific understanding of the universe, that’s exactly what it is. They just gave it a badass name.

The experimental observation did not reveal Dark Matter. Nobody has seen or proven Dark Matter, actually. That’s why it is called Dark Matter. The observation just showed that the math model was flawed, and they invented “Dark Matter” to make up for it.
My personal take is that they will one day add the right correction factor that should have been in the fomulas all the time.
Just like with E=mc² not being completely correct. It’s actually E²=m²c⁴ + p²c². The p²c² is not adding much, but it is still there.

Do you think solutions to dark matter are tied up in a unified GR + quantum mechanics theory?

Yeh, that’s how the scientific method works.
Observations don’t support a model, or a model doesn’t support observations.
Think of a reason why.
Test that hypothesis.
Repeat until you think it’s correct. Hopefully other people agree with you.People are also working on modifying General Relativity and Newtonian Dynamics to try and fix the model, while other people are working on observing dark matter directly (instead of it’s effects) to further prove the existing models.

I know, I was so hype a few years ago when a new gravity well model supposedly eliminated the need for Dark Matter, but recently it’s been in the news as a scandal that also doesn’t fix everything.
Modified Newtonian Dynamics (MOND). It’s been the dissenting voice in the modern Great Debate about dark matter.
On one side are the dark matter scientists who think there’s a vast category of phenomenon out there FAR beyond our current science. That the universe is far larger and more complex than we currently know, and so we must dedicate ourselves to exploring the unexplored. The other side, the
On the other you have the MOND scientists, who hope they can prevent that horizon from flying away from them by tweaking the math on some physical laws. It basically adds a term to our old physics equations to explain why low acceleration systems experience significantly different forces than the high-acceleration systems with which we are more familiar – though their explanations for WHY the math ought be tweaked I always found totally unsatisfactory – to make the current, easy-to-grock laws fit the observations.
With the big problem being that it doesn’t work. It explains some galactic motion, but not all. It sometimes fits wide binary star systems kind of OK, but more often doesn’t. It completely fails to explain the lensing and motion of huge galactic clusters. At this point, MOND has basically been falsified. Repeatedly, predictions it made have failed.
Dark matter theories – that is, the theories that say there are who new categories of stuff out there we don’t understand at all – still are the best explanation. That means we’re closer to the starting line of understanding the cosmos instead of the finish line many wanted us to be nearing. But I think there’s a razor in there somewhere, about trusting the scientist who understands the limits of our knowledge over the one who seems confident we nearly know everything.
That mothers shouldn’t co-sleep with infants. Every other primate I know of co-sleeps with their offspring. Until very recently every human mother co-slept with her infants, and in like half of the globe people still do. Many mothers find it incredibly psychologically stressful to sleep without their infant because our ancestors co-slept every generation for hundreds of thousands of years.
I would bet money that forcing infants to sleep alone has negative developmental effects.
The reason for this is that we tend to sleep deeper now than our ancestors. Because of this, we are more prone to roll onto a baby, and not wake up.
It can still be done, you just have to avoid things like alcohol, that stop you waking. You also need to make sure your sleeping position is safe. Explaining this to exhausted parents is unreliable, however. Hence the advice Americans seem to be given.
Fyi, if people want a halfway point, you can get cosleeping cribs. They attach to the side of the bed. Your baby can be close to you, while also eliminating the risk of suffocating them.
Maybe if you can avoid stuff like alcohol (easy for most) but also you can avoid sleep deprivation - way harder with little to no maternal leave and forget about paternal leave here in the US.
If you (Royal you, not parent commenter) can live with yourself if a tragedy occurs on your watch while you are flaunting medical advice, then go ahead and risk it, but otherwise yes! Buy the bedside attached crib!
The other thing is SIDS, if the baby can’t lift their head from a suffocation position they suffocate.
We have ours sleep in a cosleep crib beside the bed so you get the closeness and can make contact in the night.
I think something on the UK’s NHS implied the risk is primarily for mothers with various kinds of problems (including drug or alcohol abuse). Made me wonder if it’s largely recommended for everyone to cover the many people who are at risk but don’t want to think they are.
A lot of the advice is almost insultingly obvious. You get treated like you have a single digit IQ. After a couple of months, I fully understand why we were treated like that! It’s a fight to keep your iq in double digits!
The baby shaking one is the big one. It’s obvious, you don’t shake your baby. It’s also obvious that they can be safe, even while screaming. After 2 hours of constant crying, combined with sleep deprivation, I fully understand why they reiterated not to shake your baby, the urge was alarmingly strong! It also made sense why they pointed out you could leave them to scream, if you really needed to. So long as they are clean safe and fed, 10 minutes down the garden is completely acceptable.
With the original advice, telling when it will apply to you is harder than you think. The default advice has to be to play it safe. Some can be deviated from, some can’t. Deviations must be consciously made however.
Lots of stuff from both social sciences and economics.
Social science suffers greatly from the Replication crisis
Economics relies largely on so-called natural experiments that have poor variable controls.
Both often come with policy agendas pushing for results.
I take their conclusions with a grain of salt.
Economics is purely based on assumption, at it’s core. There’s no proof the assumption is true, and recent trends seem to point towards it being false.
Economics assumes people are rational spenders.
But the “economy” is often just represented by the stock market, which is both not rational, and not a good measure of the economy. It’s a great indicator of how much wealth is being extracted from the working class, but it’s shit at representing how most of the money is being spent.
The idea that animals do not have feelings. I don’t believe complex thought is necessary for emotion. You can take away all our human reasoning, and we would still get mad, or sad, or happy at things.
It’s definitely NOT science that animals don’t have feelings. Maybe 50 years ago.
Now, there’s a concerted effort to discern thoughts and emotions in animals.
I don’t think there is a scientific concensus on this. We are constantly finding previously unknown similarities between the minds of other animals and humans. I’ve put together a small lemmy community on animal communication and digital bioacoustics, it is somewhat related to this stuff.
If anything I think emotional response is the least advanced part of a human mind. However, if we’re talking about brains of sharks, small lizards, or ants then I think emotion would be a word with a lot more nuance than whatever it is they do.
that comes from religion not science
I’ve always thought the classic Hunter - Gatherer gender division of labor was bullshit. I think that theory has gone out of fashion but I always thought it seemed like a huge assumption. It seems so much more plausible to me that everybody hunted some days (like during migration patterns) and gathered others. Did they even have the luxury of purely specialized roles before agriculture and cities?
Another reason I think that is because prehistoric hunting was probably way different than we imagine. Like, we imagine tribes of people slaying mammoths with only spears. It was probably more traps and tricks. Eventually, using domesticated dog or a trained falcon or something.
You can read the dawn of everything book which is a very interesting take at a lot of those assumptions which are indeed false. This book goes deep into the ideological bias scientists have when interpreting evidence.
the ideological bias scientists have when interpreting evidence
Surprised you didn’t get downvoted here. It’s like if you tell people science is done by humans and humans arre flawed people flip out and call you a science-denier.
One of the first things you’re taught to understand when interpreting data is that you have a bias. It is impossible not to have a bias.
Take for example: 1+1=2. Is it an extremely simple equation, or a decades long mathematical pursuit to establish certainty?
Our bias tells us we can confidently assert such simple statements, but the truth is, unless we spend an agonising length of time understanding the most insignificant and asinine facts, we NEED biases to understand the world.
The point of understanding we have biases is to think more critically about which ones are most obviously wrong.
The hunter-gatherer gender division is actually proven wrong now.
Also, hunting mammoths was a very rare activity. I would expect it to be some kind of desperate activity in fact. People weren’t more crazy than we are, they would rather live than to be trampled by a mammoth.
I always assumed that hunter gatherer division was mostly down to the individual, some traits make some better at hunting than others.
I struggle to locate static objects, I for the fucking life of me just can’t see it. I’ll be looking for something and either look right over it or walk past it multiple times
But if I go outside and look in the trees I can spot all the squirrels within seconds. Not like that’s a talent or anything special, but my point is that I’d starve if I had to look for food in the brush, and likely I imagine these types of traits are what defined who did what job, meaning who was good at what, and likely considering lots of hunting was endurance based and not skill based at all, then most adults probably participated to some degree.
I’ve also gone shroom hunting and had to come back empty handed because I can’t see the god damned things.
Is this why I could never find stuff and then when my mother looked she would just go right to it?
“Fucking magnets, how do they work?”
The moon not being made of cheese. The moon is in fact made of cheese. I do not care how much a bunch of nerds insist that it is not made of cheese. I am objectively correct about this and anyone who disagrees is wrong.
I call on the FDA, USDA, or whatever agency to use their power to add lunar regolith and all otger moon constituents to the accepted definition of cheese. I also suggest all other countries to just take our word for it since only us and the nazis have set foot on the moon and who are you going to trust? Us or the nazis?

In my head, “dark matter” and “dark energy” are the names we’ve given to the limits of our understanding. At some point in the future the news is going to break that an Einstein or a Feynman or a Hawking will publish a paper titled “So we figured out what’s causing the thing we’ve been calling dark matter this whole time.”
Anything I think is ideologically motivated. Having a study to cite doesn’t make you right if the study is bullshit.
Full moons do not have an impact on people with mental illness, make weird things happen, increase work load, or increase the chance of going into labor. I have worked in three separate hospitals in three separate states and the consensus is: full moons bring out the crazies and the babies.
I believe there have been multiple studies that found that full moons affect most people sleeping and make sleep a bit harder
I sleep in a completely blacked out room yet I know when it’s near the full moon because my sleep gets very broken and restless.
It’s not true. Your observations may be affected by confirmation, bias, or other things.
https://www.dukehealth.org/blog/myth-or-fact-more-women-go-labor-during-full-moon
However, barometric pressure can apparently induce labor
Statistics shows that the belief is wrong. It’s funny I think that despite the hard numbers the people working there still strongly believe it.
The idea that SSRI antidepressants work by increasing serotonin levels. If that were the case, why don’t they start working immediately? Instead, most people don’t see positive effects for several weeks.
Plus the idea that SSRIs work, period. They only work slightly better than placebo, and they count them as “working” as long as they help with a single symptom. So if they don’t help your depression at all, but they do help with your insomnia, they put that in the “it worked!” pile. That’s why suicide risk sometimes increases on SSRIs. They do nothing for your crippling depression except increase your motivation, so before you were depressed and couldn’t accomplish anything, and now you’re depressed, but also have the wherewithal to follow through on your suicide plan.
actually studies have shown SSRIs make you more depressed than placebo
I have been having some mental health issues, and I was reading about this the other day. I was going through wikipedia with the various types of antidepressants, and it seems that SSRIs are just barely better than placebo, or even in studies not even better than placebo.
I know there are multiple classes of antidepressants out there. Are there any that do a better job, even if they are not as common?
I’m probably going to get eviscerated for this, but that sexuality is purely genetic. I think that for the vast majority of people, sexuality is way more fluid than not, and much more influenced by environment than people would like to think.
I also don’t think that has any bearing on people’s right to choose.
You can believe what you want to believe, you didn’t say it in a hateful way at all.
I’m curious about what your opinion would be of trans people going through HRT though. When starting hormone therapy you are warned of potential changes to your sexuality. I am transfem, and prior to transitioning I was bi. Since starting HRT, I tend to have an aversion to men sexually and am more lesbian aligned now.
I guess that is fluidity and environmental factors, but biological factors even still.
Other people meanwhile experience the opposite effect (which is what I expected) or none at all.
cut funding to your black hole detection chamber
I knew you’d come for my fucking black hole detection chamber you swine
First they came for the black hole detection chambers and I said nothing because I was researching Computer sciences.
Then they came for my HPC clusters
Can we not push more anti science rhetoric please
This is like the second or third post I have seen in the past week talking about “belief” in science. Science isn’t about belief, it’s about understanding. Maybe this post should be, “What facts are you questioning because you don’t understand the underlying data?”
Seriously. Science just is. I don’t care if you believe it or not. It still is what it is.
What it is, is an extremely powerful tool for reducing uncertainty about the world. Not eliminate, reduce. What it is not is a tool for “proving” “facts”. Claiming a “proven fact” is belief, not empirical science. An extremely consistent and useful theory, of course! But not a proven fact.
Science just is the way gender just is. It’s a metaphysic.
Could you link to the studies saying this?
Do you not know what a metaphysic is? A metaphysic is something that affects the world without actually existing. Information is metaphysics. Law is metaphysics. Gender is definitely metaphysics. Science is too.
Y’all downvoting me because you’re taking offense to a word you can’t bother looking up the definition of. Peak stupidity and tribalism right here. You make up your identity(which is also a metaphysic) based on imagery and social appeal and sling shit just like chimps.
Could it be that people are downvoting you because you’re using words wrong while acting like you are educated on the matter? 😉
You don’t have to take my word for it. Try Google define: metaphysics.
Chill science should be questioned otherwise it’s not science
nooo you gotta have faith in the science!! trust the science!!
Sorry I’m an heretic I guess so I must die burning (please no)
Science should be questioned by people who understand the science, not by random people who don’t understand the research. Which a lot of people who know nothing about the science or the maths/data or whatever try to question it
Right, all the people talking shit about dark matter in this thread surely all have 4 PhDs up their ass
No investigation, no right to speak
People are free to express what they think about science. There’s no law saying otherwise. Why are you guys so upset?
“There’s no law against it” is a laughably stupid reason to do something. They’re free to do it but everyone else is free to acknowledge that their uneducated/misinformed skepticism is harmful to society and that their opinions are meaningless to those who aren’t dumb. Leave the contemporary science denial to those who actually somewhat know what they’re talking about.
This is a question on AskLemmy. It won’t change anything in the world. Why do you care? You guys should touch grass
What are you on about?
Let’s touch grass together to measure how much photosynthesis grass can do? Please, it will be fun. But I’m open to another scientific experiment if you have anything in mind
The person you’re replying to believes climate change to be a lie, so I think you’re probably wasting your time.
This is a really stupid take, how do you think new scientists are made if not reaching for enlightenment to answer their own questions?
Science is about being wrong and learning.
Yes, and people that challenge the science who then become scientists actually research/experiment thenselves. They don’t go and claim science is false until they have actual reason/evidence to believe so. One can question science all they want when they do their own science on the matter and it isn’t handily disproved beyond reasonable doubt by existing evidence.
Most science deniers do not do that. Making anti-science claims without obtaining solid, consistent evidence is not science.
Op: what are some inherently enraging opinions that fly in the face of everything we know about logic?
Also op: omg guys stop downvoting these inherently enraging opinions. I implicitly made that rule …triple stamped it no erasies!!
I’m going to give you a couple examples:
-
A study showed Dementia brainscans heavily correlating with a form of Plaque. For decades people believed it, but then it was debunked. Someone expressing disbelief in it before the debunking would not have been “flying in the face of everything we know about logic.” They would have been right.
-
A researcher made a study where Aspartame used to sweeten Gatorade correlated with fast developing terminal cancer in mice. The researcher who developed Aspartame shot back by saying they fed the mice daily with the equivalent to 400+ Gatorades. Of course, a French study later showed at large scales people who consumed aspartame were slightly more likely to develop cancer in the following decades, but the outcome was still preferred to the consumption of sugar. This is an example that is much more clearcut in the favor of science, but I think there is still room for skeptics to express doubts.
I think talking about these things in a welcoming environment can both alleviate certain less scientific beliefs while also giving a great idea of how the general public views certain topics. Also it’s fun. There is a guy in here who thinks maybe a dude can fight a bear, not that they should.
Okay, but if anyone forms full beliefs from single studies, they’ve grossly misunderstood the details of how science works.
This particular hierarchy is specific to medical science, it doesn’t fit the other scientific disciplines perfectly.
Also, if I had a nickle for every conflicting pair of meta-analyses… happens so often.
Fair, but my point is that it illustrates how much stock one should put in single studies.
