2025 JJK Upgrade CRT

Not open for further replies.
The reversal increases gravity so the lapse reduces gravity.
Domain amped CTR didn't one shot Yuki, the lapse tanked the full black hole that reduced Yuki to nothingness, so that means you're wrong. Also that doesn't change anything in this discussion.
So what? I'm lost on why this even matters. What do we just now not recognize it at all
That is for the argument that Kenjaku never activated it before he was pulled inside the black hole, when everyone failed to explain how he being pulled inside even disqualify this idea when no one knows what that CT even do.

I mean I literally cannot be wrong, ctr reverses the effect of your lapse so the effect of the lapse will be the reversed effect of the reversal. Increasing and decreasing.

It's in the name. I don't know why you're acting like it's unknown how antigravity works.

Okay?
That's because her body was singularity
She would need infinite dura to survive that

Anti-gravity literally works like normal gravity
If he activated it his shirt wouldn't have torn
 
The reversal creates a field of gravity around him, the base would do the same. Cursed techs base and reversals are fundamentally the same tech just reversing the effect. So much skepticism for no reason.

For all the good reasons, because black hole wank for jjk in 2025 is a thing I'll never accept. Like it's a huge upgrade, if there are anti feats I'll go full force in stopping it ever happening, and this is not just anti feat, the calc was broken as hell.

Yep, broken physics but Gege being Gege, it does not make sense hence I say all of this are bs and should be counted as an outlier.

Yeah... Surely right? Then why don't you just scale him to Yuki's black hole directly then? For having the output to do that which can also be applied to his reversal? Because anti feat.

Thanks for admitting a biased.

An outlier for Yuki dying to it?
That's not an outlier that's a logical conclusion

We could tbh
 
Thanks for admitting a biased.
You're biased, every point I made are valid, and no one could even resolves it without ignoring anti feats.

I don't get your point here, there is no logical conclusion here, only anti feats.
We could tbh
Anti feat, so no you can't.

I've stated all I gotta say here, I don't wanna yap more than necessary. The calc was broken anyways so who cares.
 
I think we should just do that tbh (find the value needed for kenny to resist a gravitational force strong enough to spaghettify him), instead of trying to argue about black hole specifics even tho im pretty sure none of us are that knowledgeable on the matter.

Ended up not being high enough to be relevant. Only about 100 megajoules (Small Building level).

Typical width-to-height ratio for the human head is 2:3 while Kenjaku’s is stretch to roughly 1:4.

Average Young’s Modulus of the human skull is about 5 GPa.

Average circumference of the human head of a man is about 57cm.

Using the prior estimated average weight for a Japanese male of 190cm is about 72kg.

Calculating the force of extension:

F = (Ym * A / L) * ΔL

F = (Ym * A) * (ΔL/L)

Substituting Newton’s Second Law:

M * a = (Ym * A) * (ΔL/L)

Solving for gravitational acceleration:

a = (Ym * A) * (ΔL/L) / M

Substituting the area of a circle for an approximation of the cross-sectional area (A = C^2/4pi):

a = (Ym * C^2) * (ΔL/L) / (M * 4 * pi)

Plugging in numbers:

a = (5 GPa * (0.57m)^2) * [(4/1)/(3/2)] / (72kg)

a = 6.5 x 10^7 m/s^2

Calculating related mass:

M = (a * r^2)/G

Using the prior dubious radius:

M = [(6.5 x 10^7 m/s^2) x (0.37m)^2]/(6.67 x 10^-11 m³⋅kg⁻¹⋅s⁻²)

M = 1.3 x 10^17 kg

Calculation change in potential energy:

E = U1 - U2

Using the prior dubious distance:

E = [(6.67 x 10^-11 m³⋅kg⁻¹⋅s⁻²) x (72kg) x (1.33 x 10^17 kg)]/(0.744m) - [(6.67 x 10^-11 m³⋅kg⁻¹⋅s⁻²) x (72kg) x (1.33 x 10^17 kg)]/(0.844m)

E = 1.0 x 10^8 J

I'm not knowledgeable on calculations but can you explain why the yield is so far off from the original calc? It doesn't look like it uses the same method either

The part at the end is the same gravitational potential energy method as the original calc (most of the calc is just figuring out the mass from the stretching).

The huge difference comes from the fact that the calculated mass here is 9 orders of magnitude lower than the black hole calc.

1.3 x 10^17 kg (roughly the mass of a small moon like Prometheus) vs 2.5 x 10^26 kg (half the mass of Saturn).

And why is that? The effects of whatever it is Yuki conjured at that moment still far exceeds what any object could do besides a black hole. If we don't wanna call it a blackhole, the closest thing it'd be is a quasi black hole, the yield shouldn't be that far off
 
What are you on?
Who said it isn't a black hole
Are you trolling me?
Ah yes, you saying "who can tank being in a singularity please" and Yuki is literally the singularity herself (or at least, is suffering from similar force), but Yuki is fine and can yap better than Gojo can when he became Go/jo (fraudjo confirmed), meaning the singularity hasn't even been formed yet (from what you're saying) meaning no black hole meaning RAHHHHHH

The logic is there, it's just that JJK reader can't read

The stretching effect is definitely far far off.

A black hole will literally strip you down to elementary particles. This just elongates him.

But to be fair the density is still pretty insane. Roughly 6 x 10^17 kg/m^3. That is the density of a neutron star (the densest objects besides black holes).

There just happens to be a gigantic gap between neutron stars and black holes.

Its also way far off from what a neutron star would do tho?

Also while black holes could do that they don't do so immediately, so it doesn't eliminate the possibility of it being a black hole or having the mass of one. I think its way safer to assume its mass is closer to that of a black hole than that of a neutron star.
 
Yeah that isn't how you'd calc this feat going with it not being a bh. Yuki explains she can increase her VM up to a certain density till it starts affecting her. That density reached created a black pit dragging everything around her into it violently. You'd have to figure out the mass needed to do that first. Just from the affects alone, this would make the mass similar to the moon or less but with more density. iirc, even a BH with the moon's mass compressed to a schwarzschild radius of 1mm would be enough.

I mean your own article talks about how particles are accelerated up to a significant fraction of the speed of light when near a black hole. That is pretty immediate.

is the speed in which particles are accelerated the same as the speed of spaghettification?

I mean for this purpose yes.

Spaghettification happens when one end of you is experiencing a significantly higher acceleration than the rest of you, and when you are starting off less than a meter away that is going to be the case pretty much right from the get go.

If you were starting from millions of kilometres away it would be a very different story.

Don't understand this logic
Yuki can yap better than gojo and so ****** what?
Only her moving makes her better than Gojo

Doesn't matter, Fraudjo got a clean cut and still died instantly, Yuji got a bad hit and survived, yapped, created a black hole and all that shit. The only reason she lost is because Gege loves asspulls.

Yuki can yap better than Gojo meaning with the same injury, Yuki could grab Kenjaku's leg, yap, tank a freaking black hole, yap. Gojo died under 1 atm which is a fraudulent behavior. This however is not what we're talking about here, I was just messing around (though it's a fact).

Though obviously a singularity is not needed for a black hole, what I'm saying basically is, Yuki is the core of the black hole, she suffers all of that mass directly on her body and still be able to yap while Kenjaku is basically losing to it's pulling force. This makes half-dead Yuki has more dura than Kenjaku could physically bypass, who did not one shot Kenjaku with a fraction of said power and got hurt by Kenjaku after receiving only 1 of his domain hit, the scaling goes somewhere like this:

Kenjaku's domain hit >> Yu/ki's durability > Black hole >>> Kenjaku's CTR >>> Kenjaku physically = Yuki physically > Yu/ki's durability > Black hole >>> ...

If I'm not choking then this is what's happening rn.

Also I did some quick look into the anti-gravity system that Yuji's mom has (in Japanese, which is 反重力機構), and turns out it actually isn't "reverse-gravity" that would turn out to be gravity when Reversed, but literally "Anti-gravity system" as it's name implies, it just negates gravity which again reversed means gravity, make sense.

He did mention output, that means the technique needs an output to work, so there's no reason not to believe Kenjaku didn't use it before getting pulled into the black hole, it could be argued that the technique wasn't fully activated, that's all.

Trying to debunk with translations ke!!! This isn't a Nasuverse thread😭😭
 
People are bringing up the “well if Yuki suppressed it then you’ve f’ed yourself because it would be a weaker black hole!!!” thing again. I don’t think people responded to what I said about that last time so I’ll post it again.

The interpretation that the impact Yuki’s will had only affected the range of the black hole is the only one that is consistent. It can’t have been suppressing the strength of the black hole in general because… what we calculate for the black hole is the mass necessary to have the event horizon. There’s no indirectness there, if the event horizon is present we know what the mass is and you can’t devise some black hole which for some reason has a particular event horizon but a much lower mass “than usual”.


Also damn people are really throwing shit at the wall now. Tbh I think I’ll stop replying to this thread, these tier of arguments getting so far implies to me that most people viewing this thread have some kinda agenda. I’ll stick to the DB community for arguing JJK scaling.

Nah Yuki is best girl
It makes sense narratively

Since when?

Yuki lower torso is the core of the black hole which already got eaten up by the singularity

Nah actually the scaling goes like this

Black hole singularity
♾️> Kenjaku domain hit > Kenjaku CTR> Yuki AP> Yuki dura> kenjaku dura> 80 cm away from black hole

Her lower torso is what got destroyed by the singularity
 
This shit is getting ridiculous
We're seeing people claim the darkness is artistic licence and a singularity isn't needed for a black hole

But it doesn't have any spin tho?
Isn't accretion disk present for Black holes without angular momentum?

A black hole doesn’t need pre-existing angular momentum to form an accretion disk.

Besides that's not what I'm talking about
I'm talking about the fact that the darkness that was being calculated was claimed to be an artistic licence instead of what was intended, a black hole
Or, y’know, the buildup to a black hole.
 
By the way, let me make this clear—I’m not really a big fan of this feat, and I actually disagreed with it way back in 2024 in the discussion thread (you can still see my comments if you check the thread). I’m just here to address a few misunderstandings about the fight. Really don't care if Kenjaku feat gets accepted or not.
Doesn't matter, Fraudjo got a clean cut and still died instantly, Yuji got a bad hit and survived, yapped, created a black hole and all that shit. The only reason she lost is because Gege loves asspulls.

The only thing you got right is that Gojo is a fraud, but you're ignoring the fact that even a "fraud" like Yuta managed to stay alive for some time after getting hit by the same move—and even talked to Shoko during surgery.

Dude, I can also give examples from other franchises, like Bleach, where Momo survives some pretty serious injuries while Unohana gets cooked by the same thing. This is fiction. Just because one character couldn't stay alive for some time after the same attack, while others could, doesn't mean anything here. Gojo just wasn’t him in this moment, while Yuki was. Just move on from this point.
Though obviously a singularity is not needed for a black hole, what I'm saying basically is, Yuki is the core of the black hole, she suffers all of that mass directly on her body and still be able to yap while Kenjaku is basically losing to it's pulling force.

Yuki never said she needed to completely use her body to create the black hole. The fact that she was still talking while it was forming likely means that it was her lower body that got separated from her—which we can literally see falling behind her at that moment.

It was also stated that only her body and Garuda are affected by her increased mass. That makes sense, because even while creating a black hole, her upper body wasn’t affected and was still trying to pull in Kenjaku. She even had enough time to speak.
Kenjaku's domain hit >> Yu/ki's durability > Black hole >>> Kenjaku's CTR >>> Kenjaku physically = Yuki physically > Yu/ki's durability > Black hole >>> ...

If I'm not choking then this is what's happening rn.
The black hole that completely sucked in Kenjaku—something that would have cooked him if not for Anti-Gravity, self-DE buffs, Yuki's willpower, and Tengen’s barrier > Kenjaku’s Domain sure-hit > Yuki’s durability > initial stage of the black hole (which was smaller in size).

This is what I see in the scaling chain.

You’re treating both the early and later black hole feats as if they’re the same, which doesn’t make sense. The black hole at startup was small, while the one Kenjaku actually survived was much larger and required everything—Anti-Gravity, Tengen’s help, and more—to stop it.

Also, Yuki never said she could kill him with the low end version of the black hole. If she could have controlled or canceled it right after forming it, she would’ve done so—so the fact that it kept growing implies she stayed alive for a while afterward. That may have been thanks to the support of Tengen’s barriers.

And to be clear, Kenjaku only bypassed her natural durability with the mini Uzumaki in its compressed form. He has zero feats for physically damaging her otherwise.
