- Yuna: Huh, where’s Carmen?

- Yuna: Bad black hole! Very, very bad black hole!

Welp RIP Carmen, you shall be missed greatly for about 2 strips, and then forgoten to the ravages of time. Well at least Wally got a tasty meal out of this.
There ARE reasons why Wally is a black ‘hole’ after all.
Where in the world is Carmen indeed?
At least she didn’t call him Audrey 2. 😜
@ Francisco:
Yeah would end bad, first ending was better.
She did not have them spinning around each other in orbit, so the lesser mass of the neutron star was attracted and absorbed by the more massive black hole. had she have set them in orbit of each other, then Carmen may have stood a chance. So now all the information about her perpetual motion machine is spread across the surface of Wally. Hmm, how lethal would the Hawking radiation be from a 5 cm black hole?
So, how many people called this outcome in the comments of the previous strip? I know I read about a neutron star getting spaghettified…. *goes off to check*

Ah, it was David Nuttall!
Yuna’s complicit; the box was a quantized state until she observed it.
So what did she exactly expect?
Hopefully neutron star bits make a cool looking accretion disk
A mixture of rare earth elements? Directly from China. 😛

@ David Nuttall:
Interesting question. The mass for a black hole with a Schwarzschild radius of 5 cm would be a little over 5 times that of Earth. This is well into the range where all radiation is in mass-less particles (>>~10^17 g). The black body spectrum would be less than 2 Kelvin, so no high-energy photons. Neutrinos don’t have much interaction, and health aspects of graviton interaction aren’t well understood. Radiation is probably the least of the worries.
to be fair, wally was just following his nature…..yuna has only herself to blame, she should´ve given carmen her own box

I’m pretty sure that there can’t be a stable orbit for two objects like that, especially not if they’re circling each other in an relatively thick atmosphere.
As for radiation, I’m more concerned about the flash from Carmen’s spaghettification and absorption.
By the way: a 5cm sized black hole would be very very heavy: more than 3.3 * 10^25 kg (according to https://www.wolframalpha.com/input/?i=%285cm+%2F+2G%29+*+c%5E2)
That’s more than 5 times the weight of Earth itself.
I would suggest just getting her a kitten next time, but I think we all know it would end up twenty feet tall and breathing fire. Admittedly, that would probably be the cutest kaiju ever.

As I said before: It’s all fun and games until one of your pets decides to eat the other one.
Also called it, several strips ago actually. I once learned this same lesson with two Russian Steppe mice, where the dominant male ate the other one. Divine punishment was swift. The next day a cat made it’s way into my room and ate the cannibal mouse.
I think Yuna might find this article very, very interesting indeed.

Wally’s Schwarzschild radius must be much less than 5 cm, if his containment fits in Yuna’s hand.
What she expect black holes eat anything too close lol also never heard of a black hole make a burping sound.
She also treats it as sentient which poses several major issues if its sentient can it move itself?

Well, black holes wouldn’t make much of a burping sound, more like burping X-ray-radiation. So….well, it has been nice knowing you, Yuna. Then again, I’m pretty sure she has a contingency for that.

No reason why not, except for drag in the atmosphere of course. As you’ve pointed out, the black hole would have a mass of ~ 5 times the earth’s. As we can easily see in the night sky, objects can orbit celestial bodies of that mass.
The reason why astronauts cannot orbit the space station, for example, is not their size but the very low mass of both objects.
Of course drag between the objects can become important, in earth’s case this leads to satellites burning up in the upper atmosphere. Between the atmosphere / corona of the neutron star and the accretion disk of the black hole, there may be considerable drag that would make a tight orbit decay quickly. Depends on how large Yuna’s box is.
@ Mxax:
On second thought, I forgot that tidal forces will rip apart large bodies in the vicinity of other large (i. e. heavy) bodies. So there is a lower limit for the orbit radius; considering the density of neutron stars it can’t be very high, though. Something tidal deformability …
Given the magnetic properties of rare earth elements, they probably would have stuck in Wally’s throat anyway.
Has anyone seen Werner?
@ Ratfox:
This comment so made my day (although I kind of though I was maybe the only one on Earth who played that game…). It was an epic chase.

@ Ratfox:
San Diego
And so as we bid a fond farewell to poor Carmen, it’s on to the next comic arc. Hopefully it will feature Cloud and Larissa.
@ David Nuttall: Ah. You subscribe to the holographic principle I see.
@ Docward:
Yeah, I get a black body temperature of 3.6 mK, so yeah, it will not be giving off that much Hawking radiation.
@ Michiel van Geel:
No, I missed yours. Sorry, I only went back to when I recalled reading it.
@ Michiel van Geel:
And looking back, I find that David Nuttall’s comment was at 031:11, same date as yours, so it was earlier. And that was the first page that we “saw” Carmen on, so I would have presumed your strips-earlier comment (had I remembered it) was regarding a different friend being eaten by Wally. Barring fivesight or sixsight on your part, at least ^_^.
But wait, there’s vore!
@ Ratfox:
San Diego, presumably.
Or maybe Carmen just disintegrated, considering neutronium pieces smaller than 0.1 solar masses is highly unstable, not that Wally wouldn’t devour the pieces and radiation.
@ clickbait:
And all those socks that disappeared in the dryer!
@ David Nuttall:
No way is Wally 5cm, He’d have to be nearly as massive as the Earth to be that large.
Now, granted, Yuna is violating multiple laws of physics here, because a blackhole small enough to not cause the entire town to collapse into it from gravity would evaporate through Hawking radiation at a rate that would vaporize the entire town, and any black hole light enough for her to pick up would have a radius comparable to an atom, how’s she manipulating it?
But, where did she get the mass to make Wally, even if she could compress it? Wally has to be a quantum black hole of maybe a couple pounds mass, artificially stabilized somehow.
Maybe she just took a marble, and reduced the speed of light around it to the point where its minuscule gravity was enough to form an event horizon anyway?
MidoriLuna wrote:
So prior to Yuna opening the (Schrodinger’s cat) box, the system was in a superposition of both Carmen being separate from Wally vs Carmen being inside Wally’s event horizon. When our little girl opened the box, the superposition of the wave function collapsed into only one situation. So the LIGO detection would have only happened when the box was opened, not when she closed the box with Wally and Carmen inside?
Carmen who? Never mind me, been away for several days, I’ll just backread. Oh a neutron star! Oh well hello Carmen… and goodbye!

Neutrons not neutrinos. Carmen was a neutron star, not a neutrino star.
