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

[-] irotsoma@piefed.blahaj.zone 1 points 1 month ago* (last edited 1 month ago)

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).

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.

wow that sounds 100% real

[-] BussyGyatt@feddit.org 3 points 1 month ago* (last edited 1 month ago)

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

[-] Successful_Try543@feddit.org 1 points 1 month ago

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

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

[-] ada@lemmy.blahaj.zone 3 points 1 month ago

That sounds real, but I think you made it up

[-] BussyGyatt@feddit.org 2 points 1 month ago

believe it or not, no! what are the chances?

[-] Admetus@sopuli.xyz 2 points 1 month ago

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

All the dinosaurs went extinct.

[-] BussyGyatt@feddit.org 4 points 1 month ago* (last edited 1 month ago)

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.

[-] Insekticus@aussie.zone 4 points 1 month ago

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.

[-] Deconceptualist@leminal.space 4 points 1 month ago

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.

Fish only get as big as their container.

[-] Deconceptualist@leminal.space 1 points 1 month ago* (last edited 1 month ago)

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

[-] BussyGyatt@feddit.org 0 points 1 month ago

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

[-] RoidingOldMan@lemmy.world 3 points 1 month ago

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

[-] adespoton@lemmy.ca 2 points 1 month ago

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 :)

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.

[-] BussyGyatt@feddit.org 2 points 1 month ago

it sounds pretty likely, but its unscientific

[-] Deconceptualist@leminal.space 1 points 1 month ago

Hey you asked for truthiness

[-] BussyGyatt@feddit.org 2 points 1 month ago

thats on me, i set the bar too low

[-] Deconceptualist@leminal.space 1 points 1 month ago

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

[-] Fondots@lemmy.world 1 points 1 month ago

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.

[-] Deconceptualist@leminal.space 1 points 1 month ago* (last edited 1 month ago)

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 are 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.

The female lesser prairie chicken, the only remaining wild chicken, will peck holes in their own fertilized eggs in times of scarcity making it one of the only other species on Earth that perform intentional abortions.

[-] BussyGyatt@feddit.org 0 points 1 month ago

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.

[-] generallynonsensical@lemmy.world 6 points 1 month ago

Oh, so you're here to cause shit?

[-] foggy@lemmy.world 0 points 1 month ago

When I was a teen, my sister came home one night hammered. She was worried that she had work the next morning and was going to be hungover.

I told her I saw something on the discovery channel (early 00s) that businessmen do to reset their internal clocks when they travel! They put small flashlights in their socks, pointing them at the back of their knees. Yeah! Apparently if you expose the back of your knees to light while you sleep it totally resets your internal clock!.

Not only did she wedge two flashlights into the couch cushions and sleep on the couch, it placebo worked so well she went to work and told everyone about her new life hack.
