No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Firstly, cats have a higher proportion of rods to cones when compared to human eyes, as well as a structure behind the retina called a tapetum lucidum, which reflects light back to their photoreceptors.
This means they are better able to see differences between dark and light than we are, and in general are estimated to be able to see in brightness conditions about 6 times dimmer than what humans can see in.
But the flipside to this is that, in general, they see less contrast between colors than we do.
EDIT: And they can more easily be blinded by bright lights.
(The tapetum lucidum is also what causes cats eyes to appear to shine or glow in low light conditions)
...
Secondly, cats are are dichromatic, they have very low sensitivity to what we call red, so their perception or color is probably something akin to protonanopia in humans, though not as extreme.
Cats basically percieve the world in what we would call muted tones of blues, yellows, greens and grays.
EDIT: Just found this spectrum comparison, its probably better:
...
Thirdly, cats visual range extends beyond the human visual range into UV. They can see all the way down to 320nm, human vision typically stops at about 400nm.
This is why cats are often transfixed, looking at things that... don't seem to be there. What they're looking at does exist, it's just that we can't see it.
This also means that they can see distinct color patterns in what we would basically just perceive as blue.
...
Finally, they also have a 200 degree field of view, compared to a human's 180, meaning they have superior peripheral vision.
Their vision is much more sensitive to motion than humans, but they are also what we would basically call nearsighted, somewhere between 20/100 and 20/200, unable to clearly see things far away.
Nice!!! Do dogs next!
Only if you give me a treat.
Dude...

Fuck this. The ghosts are not there
Hahah!
Its usually things like dustmotes illuminated in a light band we can't see, or reflections off of metal or refractions through glass that we just see as maybe a bright spot, but they may see as ... basically psychadelic colors.
If you ever have a crystal or window where light shines through at the right angle , such that it makes a spectrum along the wall or floor...
... basically they see some kind of 'super' blue that extends beyond where our vision cuts off. The prism's rainbow pattern keeps going, we just can't see it.
Also, blacklights are probably very weird for them.
EDIT: Oh god.
They can probably always see a wide array of ... things humans can only see with blacklights.
Greeblings. Not ghosts, greeblings.
There are a couple of posts on Red-dit and Thre-eads, but I won't link to those; here's another description, although it's wrong. It attributes Greebles to Red-dit, but the term predates not only that site, but the web entirely. I first heard about greeblings in 1983.
That was fascinating as fuck
Thank you for taking the time to write this. That was an awesome read!
