Editing Talk:2088: Schwarzschild's Cat

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->

This xkcd is self-referencing as the size of cute animals is referenced to in many comics like 1871, 1682, 1903--[[User:Gunterkoenigsmann|Gunterkoenigsmann]] ([[User talk:Gunterkoenigsmann|talk]]) 21:40, 22 December 2018 (UTC) 

I think the biggest question is, what is that arrow on the left is pointing at? [[Special:Contributions/162.158.146.82|162.158.146.82]] 22:46, 21 December 2018 (UTC)

This is likely a cross between the Schwarzschild Radius and Schrodinger's cat. Below the Schwarzschild Radius, you can't tell how cute the cat is because you can't see it, just like you can't tell if the cat is alive or dead in the box.

The title text has nothing to do with Hawking radiation - it's referencing a phenomenon that happens near a black hole's event horizon. As you observe an object falling toward the black hole, when it reaches the event horizon it appears to you to be frozen in place, and gradually fades to black.

: I agree - I was going to make the same comment. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 16:34, 21 December 2018 (UTC)

However, Hawking radiation describes the decay of black holes and so the black hole would get smaller and smaller, but I believe that you are also correct.

For the title text, I thought of the Cheshire Cat. [[User:Elvenivle|Elvenivle]] ([[User talk:Elvenivle|talk]]) 23:31, 21 December 2018 (UTC)
:Presumably The Cheshire Cat is able to change its size at will in order to vanish. As this doesn't change its mass eventually it passes the Schwarzchild Limit, beyond which information cannot escape. This is why the Cheshire Cat, like Mona Lisa, has an enigmatic smile - it's not possible to know why it smiles, as that would constitute information transfer.

No offence Elvenivle, but I don't think this has anything to do with the Cheshire Cat. I vote we change it. [[Special:Contributions/108.162.245.244|108.162.245.244]] 23:35, 21 December 2018 (UTC)

'''Going off on a tangent'''

Sorry, I know this has got nothing to do with explaining the above comic, but when I read the title text a thought struck me: if the cat is getting cuter and cuter as it shrinks, a cat lover will get happier and happier as it increases in cuteness. However there will be a point that the cat lover will become sadder as they realise that the cat is going to disappear from their view forever. I would be interested in seeing the curve of cat lover's happiness against cat size, and seeing if we can determine the optimum size for "Cat Cuteness". 

And now, having defined the unit CC, I am never going to be able to watch a medical drama in the same way again... [[Special:Contributions/141.101.98.46|141.101.98.46]] 10:23, 22 December 2018 (UTC)

So according to the graph, a tiger would have very little cuteness, which might be true if said tiger was in the process of attacking you for his lunch.  Otherwise, there are lots of tiger videos on Youtube that could be easily described as ''cute''.  [[User:Nutster|Nutster]] ([[User talk:Nutster|talk]]) 16:57, 22 December 2018 (UTC)

I googled something like "how do black holes form if time stops at the event horizon" and found the variety of expert-sounding answers to be quite engaging, [https://www.quora.com/If-time-stops-at-the-event-horizon-of-a-black-hole-does-it-mean-that-matter-from-the-accretion-disk-never-really-cross-the-event-horizon-If-so-how-do-black-holes-grow-in-size for example].  The simplest explanation to me seems to be that the matter mostly just stays on the surface forever, from our perspective, but the top-rated answer from that link is that space-time curves so much that the matter is no longer traveling through space and instead is falling through time itself!  A statement like that sounds really cool and likely true, but could use a reason backing it up. [[Special:Contributions/172.69.62.232|172.69.62.232]] 21:58, 22 December 2018 (UTC)

I don't think that has anything to do with Schrödinger. Simply, the cat gets smaller until it's smaller than its Schwarzschild radius and it becomes a black hole, and so its size is determined by its Schwarzschild radius.

-This isn't technically for the comic itself, but the Incomplete banner on this page was so funny that I just HAD to preserve it "This explanation may be incomplete or incorrect: Created by a SMALL CAT WITH NO CONCEPT OF FIELD EQUATIONS. Could use more information on the relevant theoretical physics. Do NOT delete this tag too soon. If you can address this issue, please edit the page! Thanks.

-'''Slightly Disappointing''' that no one posted a picture of a tiny kitty (one that could be on the leading edge of that critical limit).

-'''Schwartzchild's Cat''' is local maximum of smallness x cuteness.
-I think the Schwartzchild's Cat is the smallest (and therefore, cutest) a cat can be before making it smaller saddens the human because it's now too small.
-An alternate theory is that the critical limit marks the point where the small cat has become so cute that it cannot be seen, because a larger, grumpier cat has mailed it to Abu Dhabi. -- [[User:C.Robin|C.Robin]] ([[User talk:C.Robin|talk]]) 01:05, 27 September 2020 (UTC)
