There are 9 planets…
There are at least 9
Pluto is a dwarf planet. Planet. You wouldn’t say that a dwarf person isn’t a person.
Speak for yourself
You wouldn’t call a person a dwarf, period. So don’t do that. If you ever meet a little person, they’ll probably refer to themselves as a little person. You should just follow their lead
A dwarf planet is not a category of planets. It is a category of sub-planetary objects. This is how the term “dwarf planet” was adopted by the IAU in 2006. It did used to mean “type of planet”, but there are just too many of them, and they’re really too different from planets, so it literally does not mean that anymore. At least to astronomers.
Whatever a red car is still a car.
It’s dumb to say it isn’t a planet just because it hasn’t yet cleared its orbit. The decision to make it “not a planet” was also made by astronomers, not by planetary scientists. Like people with “Star” in their name know more about planets than people with “planet” in theirs.
Anyways it’s extra silly because if you have “real planets” and “dwarf planets” then what is the higher group containing those two? “Things that orbit the sun”? No, they should both be planets.
I’m not going to argue with astronomers about how they define planets. I do my job, they do theirs!
What about Uranus
Edit: or is that a moon 🤣 I crack myself up!
I’m sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.
Oh…what’s it called now?
Urectum.
Lmao I love Futurama
I’m torn on this one, cause recently they’ve been finding evidence of a ‘new’ 9th planet, way beyond Pluto’s orbit. So I’m on the fence of “there are 8 planets” and “there are 9 planets.” 🤔
I’m of the believe that we made up the word planet and it can mean whatever we say it means.
That’s pretty much how it is. In ancient times, planets would have been objects that were distinguishable from stars in ways they had the ability to differentiate from. For example, with a telescope, any object that doesn’t shine like a star, that moves across the sky at a different rate than the stars, or maybe has visible rings.
Then once science found things that past science couldn’t account for, they redefined what a planet was, according to its size/gravitational pull or other factors, and which Pluto didn’t fit. Apparently due to Pluto’s small size, it’s not even a dwarf-planet, and by that measure is basically just a really big asteroid (we even know of asteroids that are bigger than Pluto).
I’m of the opinion we made up all the words, but those mouth sounds must have a strict meaning whenever possible. Words are important, they’re how you communicate concepts. Everyone should be precise with their words to the best of their understanding, if you have to redefine the word planet in every conversation the concept is diluted and you waste a lot of time
In this case, if Pluto is a planet, we have at least 13. We might discover another 10 or 20 if there’s no planet 9 hiding behind the kyper belt and it’s all dwarf planets… Ain’t no one got time to remember 30+ planets
30+ planets should be pretty easy. They name them after mythology. The 50 states aren’t difficult to remember, and those don’t have any sort of naming convention.
The issue is, as I understand it, we either have 8 planets (or 9, if there is an exoplanet), or a whole bunch of planets, depending on how narrowly we define them.
Yeah this is the correct take. Either Pluto (and by extension, any object of similar size) is a planet, which would mean there’s thousands of Pluto-sized planets in the solar system; or pluto is ‘too small’ to be a planet. Which is the answer they (Sci community) settled on, because if every comet/asteroid is within the threshold definition of ‘planet’ then there would be no point in distinguishing planets at all.
Kinda like how we have dwarf-stars and supermassive stars 1000x bigger than our sun. If they were all the same size there would be no point defining them beyond ‘star’.
Pluto being too small isn’t actually the grounds on which it got demoted. The size requirement is just being massive enough to reach hydrostatic equilibrium - that is, be heavy enough that it’s round. Pluto does meet this one
The one it fails is clearing its orbit. This basically means being much heavier than everything else in the same orbit. Be gravitationally in charge of your orbit. The other eight are all hundreds if not thousands of times heavier than everything else in their orbit (not including moons, since they’re gravitationally bound to the planet anyway), whereas Pluto is less than a tenth of the total mass in its own orbit. Ceres is actually more gravitationally dominant over its orbit than that, although still nowhere near the eight planets.
This one sounds a bit weird at first, but I kinda like how it has such a massive delineation between the things we instinctively think of as planets and everything else.
It’s also the fact that Pluto doesn’t have its own orbital slot. It is clearly something that escaped Uranus at some point, that’s why their orbits intersect. A planet doesn’t just have to have a certain size, it also has to have its own distinct orbital path.
Recently? I’ve been hearing about a possible large trans-Pluto object since before Pluto lost its status as a planet.
I must not be on the more scientific news places then, I didn’t start hearing about it until around last year–maybe the year before–, well after pluto got thrown out like last night’s trash.
There’s been “planet X” theories since the 50s
Happy cake day!
RIP Pluto
Varies too much person to person to be valuable
Back in my day the only planets we knew of were the ones in our solar system.
And there were nine of them!
That’s still very much the case. All planets are, by definition, in our solar system. Any planet-like bodies not in our solar system are called exo-planets.
Did you hear about Pluto? That’s messed up, right?
the human named Jerry has something to announce…!

Not really, no… it’s a comet or at best a rogue kuiper belt object. It’s smaller than earth’s moon, its orbit is wildly elliptical, and it hasnt cleared out its orbital path. Many reasons not to consider it a planet, and so it was dropped.
If Pluto was to be called a planet, then Ceres would also need to be called one, and everyone seems happy with calling that an asteroid.
You make it sound like exoplanets are not planets, but they are, unless you have a recent source that contradicts my education.
Sure, how about this https://www.dictionary.com/e/exoplanets-and-planets-the-truth-is-out-there/
Might work for some countries, but the problem is that schools in the USA completely lack centralization: each school district is its own separate governing body. Jason was taught that Pilgrims to America were persecuted Christians seeking adventure and made treaties with Natives, while Derek was taught about socioeconomic nuances of 17th-19th Europe leading to incentivized settlements particularly attractive to hardcore religious extremists who then waged relentless war on the Native Americans.
There are no Universal Lies that everybody was taught, except for Dark Matter.
What’s wrong with dark matter (and energy)?
That was just a bit of snarky commentary, no need to read into it.
Dark matter fits what we observe the best out of all of our models, but we’ve never observed it despite the many massive detection chambers we’ve built or probes we’ve sent out.
There’s a big debate now about whether dark matter really exists or there’s a better explanation for how most of the mass of the universe seems to be unable to be perceived. Related to gravitational waves lately I believe.
Take this for what it is I’m not a scientist I just occasionally read science articles.
I think you’re getting confused with dark energy. There is very little debate about dark matter–it’s an observation that many many many people have made.
Dark energy is the name for whatever is causing the
explanationexpansion rate of the universe to increase. There’s quite a bit of debate about whether the expansion rate even IS increasing. And the amount of increase is different according to how you try to observe it. So yeah, there’s a lot of debate about whether dark energy is actually a thing, but there is very little debate on whether there’s more matter than we’re able to observe, something that we call dark matter but which we don’t really understand. Similar names, but totally different concepts!I thought the only observation we have of dark matter is via cosmological models.
It’s an interesting idea, but it assumes that physical forces are getting WEAKER over time, and that’s a pretty big assumption. It’s not very parsimonious.
I’m not a subscriber to this particular theory, but I do think model error is a more plausible explanation than magical, undetectable mass.
The mass is definitely detectable–it’s just not visible. And it’s detectable in several different ways that all match, that’s the key here. This is definitely an observation.
It’s long been stated by astronomers it’s an ad hoc theory until they figure out what’s going on.
Dark energy yes. But lots of cosmologists seem convinced dark matter is proven fact. Why are they so certain?
ITT: People misinterpreting the idea as “facts that your school taught wrong”, when it’s really saying, “things that have changed since you went to school” (either through a change in definition or by new research).
E.g. If you went to school before the early 2000’s, you were taught that Pluto is a planet, while that is no longer true since it was recategorized in 2006.
This is the wrong aporoach.
You should build a mockup site, use it to raise 2M$ for the startup behind it you just created arguing you’re about to collect personal data about the age, education level and place, curiosity, etc. with overinflated numbers on their real values.
Then you hire a bench of students, or better: launch a competition for the best “fact you were told that turned out wrong” with a 1k$ prize that you eventually give to some biz angel’s investrent adviser’s child.
Once data are acquired, claim the company is now worth 10M$ and raise that much in a new round.
Finally, sell the company for 20M$ either to a tech company that will enshitify, paywall and crater it.
You still don’t have your website, but now you’re rich and you no longer care about these things.
Everyones first friend, Tom had the right idea. Check-in and cash-out, how much do you really need to live a happy fulfilling life? He’s chilling on a tropical beach taking pictures of sunsets right now with no intention of going back to his old career.
Just read the wikipedia list of common misconceptions
list of common misconceptions
The Middle Ages were not “a time of ignorance, barbarism and superstition”; the Church did not place religious authority over personal experience and rational activity;
Like hell it didn’t.
and the term “Dark Ages” is rejected by modern historians
Because it’s a prejudicial term, not because the past isn’t fucking shitty.

We generally say ‘Antiquity’ and ‘Late Antiquity’ anymore.
Ooh present-tense anymore! Really don’t see that very often, but it’s got a nice ring to it
Edit: it’s a positive anymore not present-tense. Thank you @[email protected]!
Can you explain please ? I don’t understand their sentence as it is. What’s surprising to me isn’t the present tense, it’s the fact that it isn’t negative.
It sounds odd to me too, but I found a wiki article on it: https://en.m.wikipedia.org/wiki/Positive_anymore

I sent the Twitter image to chatgpt to convert the image to text and then I put that text into websim which generated a website that does exactly that and it even handles if you graduated recently and it will link you to a timeline of debunked “facts” here’s the link, enjoy! https://websim.ai/c/GeEMLk9DuUC23jV9S
I got: “We only use 10% of our brains. Modern neuroimaging has shown that we use most of our brain.” In the 90’s I thought this was not in fact, but urban legend, the whole time.
Also: “Christopher Columbus discovered America. Indigenous peoples had been living in the Americas for thousands of years before Columbus arrived.” I didn’t realize that it was implied no one was here when he came.
I feel like this site is going to be a great source for many of these
Vikings discovered the North American continent long before Columbus. Fucker got credit for copying someone’s homework.
And yet, in the end, it was Amerigo Vespucci who the entire western lands were named after.
I think that brain one was from a game of telephone with the real fact that a large portion of our brain is dedicated to image processing and object identification. Another portion would be dedicated to sound recognition with a decent amount of circuitry going into the recognition and parsing of speech. Memory will also take up some of the capacity as well as mapping desired actions to sequences of signals for muscle activation. After all the things our brains need to do just to accomplish all these things we take for granted are accounted for, it doesn’t leave much capacity left over for thought.
Though, at least in my experience, the most powerful analysis the brain can do is in the subconscious. So many times I’ve faced a difficult problem where I’ve been unable to make any progress, take a break, then later return to a much easier problem. Or even with skill development, try doing something too hard for a bit, then sleep on it and try again the next day and it might suddenly be easier. This works best for dexterity skills, I’ve noticed it a lot in Beat Saber.
So it’s like you can take whatever was left over from the first paragraph, then take a small amount of that and that’s your conscious thought capacity and the rest is given to subconscious processing.
hmm I do this all the time for anything to do with solving problems, I work on the problem relentlessly until my head is clouded and clearly fried and then I come back later and try again
yeah idk how good the website it made really is but it sure is interesting that it could just do that on the fly
yeah the issue with “discovered” is cultural interpretation, not factual. If you assume that indigenous people don’t count, or if non-aristocrats going there doesn’t count as discovery, or if it was discovered by Asian peoples but not yet by Western peoples…
I dunno if a fact-checking website can get into it as it is figuratively and literally critical race theory (ooOOOOooOOOoh!) to have that discussion.
I think having something that gets vetted by experts would be better, but this might be a good starting point.
Lemmy Kiss of Death? Or API rate limited or… both 😅
I didnt graduate highschool though. Quit at 16 to go to work full time got my ged at 29
An even better idea: make your OWN list! Don’t expect someone else to tell you the truth if you’re not working to search for it yourself!
Curious how you would go about this process of creating a list of your own knowledge that is outdated.
By being a life-long learner! Seriously, learning is an active thing, it’s not something we have to be sitting in a room to receive. So as we read and learn more, we realize that some of the things we learned are different from what we thought. It’s something we should all be doing as we learn and reflect.
Right… And the suggestion in OP is for someone to create an efficient tool supporting life-long learning. One doesn’t imply lack of active learning in the other. So get of your condescending high horse.
By consuming very large amounts of informative media
My teachers told us, with all honesty, than the reason “the blacks” (yes, they said it just like that in a tone you expect) are better athletes is because they have an extra muscle in their legs.
This was while there were African American students in the class. In second grade.
I could throw a site together if the community is willing to help curate the data.
From what I read here are some keys to follow:
Year Taught: Year of irrelevance: Country: Fact:
I could throw a form together for submissions to feed this site. Thoughts?
You’d probably need to verify all submissions
Unless you throw an LLM into the mix
Or maybe there’s already some resources giving you all debunked facts with their dates
LLMs are not magic, otherwise one just have to request that any submission will have references to reputable sources.
I would probably start out by proofing or approving them before they post to the site. It say I get a notification read it do a little reading over it and get to a point where I can use a large language model to siphon the submissions.
You believe an LLM can be used to distinguish facts from fiction? I wonder up to which year that misconception was taught in school.
The whole point of LLMs is, to convince their users that the “facts” they generate are actual facts.
LLM is plausible deniability!
They can browse the web, and I never meant it would be 100 accurate just easier. Don’t think this is going to be a mission critical website
That just it, these “facts” won’t be on the web for stuff approximately 2005 and before. No where on the web is the racist and homophobic shit I was taught in the 80’s and 90’s listed on some wiki.
LLM’s are mostly useless anyways at distinguishing real information, they are just shit summary tools and poor search engines.
For America, you’ll also need to have a drop-down for states. I graduated from high school in California in 2009, and I’m currently working on a medical degree, so I’d be delighted to contribute to this. I’d especially like to help with a sex ed section for Americans.
I’m not sure I’d want to get that granular because of the same fact was taught across the country there’s no need for the redundancy. Also trying to make this a global website helps removing that level of granularity from the states as well.
The differences in curricula across states mean that some states would have gotten the correct information while others may not have. I know the science and history classes in my state were pretty different from some other states.
Thats not just the case in the US though
That’s part of my point. My American education was pretty limited on the internal politics and civics of other countries, but my husband who went to high school in a different state did get a decent amount of information about how modern/current European countries are structured. So I guess it’s safe to assume that other countries will also have differences across regions.
Design it so that it can get that granular later(when someone else wants to do that work)
As long as it’s got the capability it can grow into that later. Assuming unexpected and explosive popularity/growth it would be great if wikifoundation acquired it someday as a dataset if nothing else, but having a structure that can be expanded globally at a granular scale baked into it from the beginning would be awesome
Sorry I’m not great with computers or i would offer more of a technical opinion not just design commentary
I graduated from high school in California in 2009
Hey, me too
I’ve actually seen a website that is exactly this.
Can’t remember the URL, but can confirm it exists (existed?) and it was an interesting website to read.
Same, I want to say it was a NYT page? Or something like that. Not a dedicated site.
Could be, it’s been a while. Or maybe there’s been multiple sites.
Likely, yep!
people who dropped out: “I know all”
Okay but should I put in the year I graduated or the year of our textbooks/curriculum? Because my U.S. history textbook had an assignment for the “present day” to write about the “ongoing” war in iraq under “current” president George W. Bush. Spoiler, I did not go to HS when bush was president.
I was in high school during that time
It’s really weird to see actually witness history becoming “history”
I think that already exists? I remember seeing it on Lemmy some months ago. I’ll try to find it.
I remember seeing one on reddit a few years ago exactly like this.
I was gonna say, I’m pretty sure I’ve seen this exact website before
