whoa what a coincidence, someone asked the exact opposite question as me

Fish only get as big as their container.

so do they just grow as much as they eat instead?

here's one: pluto is not a planet. i remember they told us about this in school but it turns out that wasnt true, it was just made up.

So... Bonsai fish? Can I make a regular fish into a starfish shape? I mean I wouldn't, cuz that would be cruel; I'm just asking in principle. Because that's where this would seem to lead lol

I didn't bang your mom.

it sounds pretty likely, but its unscientific

All the dinosaurs went extinct.

Quantum entanglement can transfer information in a way that isn't bound by the speed of light.

didnt i read that birds are a direct lineage offspring of dinosaurs? i think that one is actually not made up. hm, wait. does it count as extinct if you produce offspring that survive but they arent your species anymore? or is that just dead.

All humans have 46 chromosomes and as the most complex organisms that's the highest number among all species.

sounds legit.

Relax my dude, he's just playing off the observation that pluto discussions get weirdly heated on the net. I don't think he was coming at you from any angle whatsoever.

[Apologies for the presumed male pronouns throughout]

I wasn't? lol I just wanna clear up misunderstandings and keep the peace so Lemmy doesn't become reddit 😬

Just saw that you explained much better. Cheers 🍻

oh my bad, i missed it completely. im pretty tired and a lil drunk. its funny now i see it.

that makes way more sense than what i was thinking, thanks for catching me up

Perovskite photovoltaic cells are named after Andrej Perovski, who invented them in 1965 in St. Petersburg. The technology was shelved for decades due to poor longevity and high costs at the time, and Perovski never lived to see it picked up again and developed like it is now.

Hey you asked for truthiness

wow that sounds 100% real

thats on me, i set the bar too low

Yeah actual answer is that only the non-avian dinosaurs died out (along with many other creatures, including some that folks mistake for dinos like pterodactyls and plesiosaurs).

But birds are obviously still around today and they are true dinosaurs according to most biologists/zoologists/geneticists/etc.

'Species' is an astonishingly hard thing to define though so I'm not gonna touch that one.

Na, dinosaurs still exist today as birds. Hence why palaeontologists refer to the prehistoric dinosaurs as "non-extant dinosaurs" so as to exclude the Aves clade.

you can tell species apart really easily! if they mate and produce offspring theyre in a species. its that simple!

They stop growing because they die. As they grow the water quality gets increasingly poor, which slows their growth and eventually kills them.

There is a small chance that this is actually a true fact, but I've never been able to find any source that backs it up. I haven't looked hard, but I have looked, and my google-fu is usually pretty good

I remember hearing once that "blue raspberry" flavor exists because when food scientists were trying to come up with a formula for artificial raspberry flavoring they just couldn't get it quite right, they got pretty close, but not quite close enough for people to buy that it tastes like raspberries. But some marketing guru decided it was good enough and they'd just color it blue and people would accept it "of course it doesn't taste like regular raspberries, this is blue raspberry, it's different, it's supposed to taste like that"

And yes, blue raspberries kind of actually exist. They probably used that as justification banking on the fact that most people don't actually know what they taste like.

There's also some stuff about a certain red dye being banned at one point, and marketing also wanting to differentiate raspberry because people already associated red with flavors like cherry, strawberry, watermelon, etc. and those are probably true as well, but I don't think those reasons are incompatible with this explanation.

I think the marketing history of using blue to distinguish raspberry from other red fruit flavors (cherry, strawberry, etc) is true. Sources also say candy and drink companies wanted to get away from unsafe Red 2 dye like you mention.

Fruit flavors can be complex combinations of esters and other compounds. But the core taste/scent of raspberry seems pretty straightforward though, mostly just a ketone and ethyl formate.

Oh crap sorry, I read your title too fast. I thought it was a repeated post!

*offspring that itself is fertile. Otherwise e.g. horses and donkeys would count as one species.

Here’s a few for you:

Electricity is electrons flowing through a conductor.

In an atom, electrons orbit around a collection of protons and optionally neutrons.

In an atom, electrons exist as energy “shells” at varying layers around the proton/neutron core.

Bonus points to the people who can explain why these are all false and what the reality (as we currently understand it) is. Transformers are a clue for the first one :)

Yeah, everything is bound by the speed of light in its own relative frame of reference. It just appears to move faster to an outside observer. Also, entanglement isn't slowed by a physical medium like wires or optical cables, which in practical terms means it can be faster relatively than current optical or electrical signals.

Relativity, time dilation, multidimensional physics, etc., are so cool, though the details are often simplified to make it easier to understand in our local frame of reference (like most Newtonian physics we learn in school).

Math in it's entirety is completely made up yet everything comes up as facts.

For the rest made up things are not facts at all. Or so I think. Might be wrong.

edit: typo

For the electricity one, I'm guessing you're thinking of AC, where electrons move back and forth instead of continuously. But DC current does actually involve electrons moving continuously in one direction. Even a DC transformer is theoretically a thing, though I've never known one to be used as a transformer (usually a similar thing is used for electrical isolation, but it's a similar idea under the hood).

Or you're making the distinction that electrons don't move through a conductor, they move along (the outside) of a conductor (mostly).

I think due to genetic mutation that some humans have 45 and some have 47, but by and far the largest majority of humans have 46 chromosomes.

Having to walk 10000 steps a day. It was a made up commercial marketing campaign from japan, iirc

in a way that isn't bound by the speed of light

But also in a way that is utterly useless for faster-than-light communication.

Isn't quantum mechanics fun? :)

I saw a bird today, so no, they didn't.

What about grolar bears and pizzly bears? They're fertile. Does that make polar bears and grizzly bears the same species?

It was true at the time, but it isn't true anymore.

Since then, we nailed down the definition of "planet", and Pluto (along with Ceres, Eris, Haumea, Makemake, and others) don't meet the requirements.

According to this definition, yes.

The question ist on 'facts' that aren't true and superluminal information transport due to quantum entanglement is one of these.

Exactly, hence it's an untrue (or made up) 'fact'.

It's the second half that makes it really false (although the first "all" is sufficient): there's a single-cell animal with 16000 chromosomes.

Dogs always poop facing north.

That sounds real, but I think you made it up
