2088: "Schwarzschild's Cat"

Postby fluffysheap » Fri Dec 21, 2018 5:17 pm UTC

Title Text: "Cats can be smaller than the critical limit, but they're unobservable. If one shrinks enough that it crosses the limit, it just appears to get cuter and cuter as it slowly fades from view."

The smallest possible cat is known as a Planck Kitten, and these are a candidate for dark cuteness.

So if the Schwarzchild's cat just fades from view, how do you tell it from a Cheshire's cat?

The Cheshire Cat shows very little red shift.

There are some intriguing synergies here with https://xkcd.com/231/ . Like, what happens to intelligence if the cat is decreasing in size while being accelerated towards the observer? Or something; proof is left as an exercise.

Not only that, but the entire theory fundamentally rests on the assumption that the only thing that makes cats cute is their appearance. I disagree with that assumption. The cutest kitten I've ever seen was not even close to the smallest kitten I've seen, nor was there anything remarkable about the way he looked. He was a pretty ordinary 4-month-old kitten aside from his incredibly sweet disposition.

I disproved this with a cat and a band saw. On the right side, my graph shows a sharp discontinuity.

This makes me wonder where the attack "panthers" in Team America fall on the plot. Are they big or small/cute or not?

I'm going to assume based on the name that is only applies directly to non-rotating fuzzballs with no net electric charge.

What of critically-sized cats with a moment of rotation (Kerr Kats?), a net electric charge (Reissner–Nordström Cats?), or both (Kerr-Newman Kats?)

Has anyone detected the rippling waves of winsomeness when two small, cute cats get into close proximity and eventually hug?

There no longer is a Chershire cat. They changed the county boundaries, so now it is the Unitary Authority of Warrington cat. Or UAoW Cat for short.

This would also explain the lost time spent with kittens. What seems like a few minutes is really a few hours: time dialation. :D

What about the other end of the chart? As a cat's size approaches infinity does its cuteness approach zero or does it approach some other non-zero value. I for one believe a cat can never have a cuteness value of zero.

Are we only considering housecats (Felis catus) or any member of the Felidae family, even extinct? Because Smilodon has about zero cuteness.

Don't cats above a certain size undergo exothermic fission, producing a lot of smaller cats, various other species and a kind of gooey blob?

Hmmmmm... No.
The cutest cat (well, apart from jaguars, anyway) I ever met was a little bigger than a fox.

Of course the cutest cat of all time was the sabretooth tiger. Especially if you were another sabretooth tiger I imagine.

Depends on whether we're talking fully grown tigers or some hypothetical genetically engineered cat designed to resemble a scaled-up version of housecats. Presuming the power associated with such size didn't corrupt them absolutely, perhaps the cuteness would hit a non-zero vertex at a given size threshold and begin to increase beyond it.

Let us carefully modulate the Cringer/Battle-Cat embodiments, to establish more towards the upper limits.

I seemed to be the most interesting person he'd seen that day.

The cage is regrettable but at least zoos keep endangered species alive better than people in general do.

Clouded Leopard, though ocelots are about the same size.
I've gotten to know one of those fairly well too, but he's shy and grouchy.

Do they fade from view, or do they just get better at hiding until they're impossible to spot?

Cheshire's cat is always smiling, even when it's not a cat.

I think "size" can't be naively taken to mean either volume or mass (for example a healthy cat is definitely cuter than a scrawny one, and a tubby one arguably cuter than a healthy one). I think this graph holds true only for house-cats of platonic proportions.

There is an unexplored emergent property as you move to the right on the graph... At some point cats become "majestic" with an increasing magnitude.

I have never observed a "Majestic" thing that I thought was cute... nor a cute thing I thought was majestic. So I find myself wondering if they are inverse relationship entities.

"Majestic" seems to have roots directly related to greatness; so, yes, it seems totally fair to say that's proportional to physical size, and inversely proportional to cuteness.

Wouldn't "inverse to physical size" mean that smaller things are more majestic? Inverse to smallness (size-1), maybe?

I don't know, I personally know a rather large tabby who tends to look quite regal in his bearing, but can also be downright fuzzdorable.

Snow leopards can be pretty cute sometimes, and I doubt anyone who's seen one would say they aren't also majestic.
