So, as this thread pointed out, the High 4-C feat done by Kirito is done in the same instance where stars are described as the hopes and dreams of people instead of actual, proper stars, so it's a bit wack to use that for the star king's certain level of power. But, also, the shaking of the universe he did was pretty severe, so, why don't we do something with that?
So, it's described as "sending ripples" across the innumerable stars stars that Steeka is beholding, which is a bit higher than what I believe we assume to be a magnitude 3 or 4 for shaking the universe by default. You could probably argue that this effect only stretches across more local constellations that they're witnessing, and... yeah, that's fair. But, for the low end where we assume that the world of Alictization isn't an entire universe (Considering that such a fact is unknown), it should apply, and then we can debate about the higher end, once the math is overwith.
So, what Magnitude would something like this be? Well, the Mercalli scale describes an event like this as a XII, which seems a bit high to just go with as a default assumption, so, let's be a bit more conservative and say anywhere from X to II, which on the richter scale that we use for these calculations would be 8-9.
So, for the low end, we get this description
| “ | I exhaled and surveyed the unthinkable scene before my eyes again. Stars of breathtaking density stretched in a band from top right to the bottom left of my vision. I suppose you could call it the Milky Way, but no matter how I lined up the potently glowing stars, I could not recognize a single familiar constellation from the real world. This was Underworld, all right. | „ |
So, the underworld is described as like the milky way, so there is at least one galaxy in it's makeup. Probably more but it's a big vague, so let's just use the milky way's radius of 52850 light-years, 5e+20 meters
Now, to apply inverse square law and see how far the energy needed to make these quakes is spread, we need the surface area.
4 times pi times 5e+20^2 gets 3.14159265358e+42 Square Meters.
That times the energy needed to make a magnitude 8 and 9 earthquakes (6.309573e+16 and 1.995262e+18 joules would be...
Low End: 1.98221081840e+59 Joules, 1.9822108184088 Petafoe, Multi Solar System level
High End: 6.26831300755e+60 Joules, 62.683130075574 Petafoe, Multi Solar System level
We're also told this is 20% of his full power, so the real, full 100% would be...
Low End: 9.9110541e+59 Joules, 9.911054092 Petafoe, Multi Solar System level
High End: 3.1341565e+61 Joules, 313.415650377 Petafoe, Multi Solar System level
Now, since we don't get the confirmation that these high power effects are reaching the very ends of the universe, much as we don't get the confirmation of Project Alictization being universe sized at all, it's not entirely certain if we should assume as much. But, since we already have Kep's calc for the Magnitude 4 low end, I will just go ahead and do it.
2.4320086e+54 Square meters, times 6.309573e+16 and 1.995262e+18 are...
Low End: 1.5344936e+71 Joules, 1.53449357983 Ronnafoe, Multi Galaxy level
High End: 4.8524943e+72 Joules, 48.5249434325 Ronnafoe, Multi Galaxy level
100% would be...
Low End: 7.672468e+71 Joules, 7.672468 Ronnafoe, Multi Galaxy level
High End: 2.4262471e+73 Joules, 242.624715 Ronnafoe, Multi Galaxy level
Note[]
I made a blog on shaking the universe all the way back in an attempt to revise Kep's numbers and it was... ill conceived, to say the least. I used the value for shaking the entire planet, IE, create a Magnitude motherforking 11.2328648415393 earthquake across the entire universe, as opposed to a Magnitude 4. This uses the right values, and thereby doesn't inflate it to a massive degree. Or at least, shouldn't, but I'm still not certain I didn't botch one or two things here.
Edit[]
Apparently even the universe actually shaking wasn't all that supported, since it was at the sight POV and not an omniscient narrator.
The only thing really confirmed is that the stars were indeed shaking, so we're going to have to use the distance between Alpha Centari and the Sun, 4.014188e+16 meters
Probably a lowball to use that as a radius given everything, but, let's just go with it.
4 times pi times 4.014188e+16 is 5.0443774e+17 square meters
That times 6.309573e+16 and 1.995262e+18 joules would be...
Low End: 3.1827868e+34 Joules, 7.607042907 Yottatons, Large Planet level
High End: 1.0064855e+36 Joules, 240.555797432 Yottatons, Large Planet level
Yeah.
