Standard calc for Surface Wiping (Calc group discussion)

[RKGenki]

Right now, the calc for Boros' CSRC is used as the standard for surface wiping feats from statements.

Recently, another calc for the same kind feat was made during revisions for Bayonetta, giving different results.

Now it needs to be discussed which one is best/most correct to use for standard surface wiping feats


Disclaimer: I'm not knowledgeable on calcs myself, so I'll leave the discussion to the calc group

Should i highlight this?

 

[RKGenki]

I think it's highlight worthy, yes

 

[AstralKing7]

interesting interesting

Pretty sure the 366 petaton one (on first look) is correct.

The 60s one, aside from assuming a timeframe which I do not encourage, makes the mistake of assuming that the athmosphere is moved. Per defition a shock wave doesn't actually move the medium (transport mass) it is travelling through a lot, meaning that wiping the surface via a shockwave doesn't involve KE of moving the athmosphere to the other end of earth.

So that only holds under the assumption that the feat involves moving a huge amount of teh athmosphere which isn't soething one can default to without showing it specifically.

@DT

FYI, the 60s one isn't the one that's being considered.

 

[WeeklyBattles]

@DT We're trying to figure out which one we should use, the Bayonetta calc or the Boros calc as a standard

 

[Kepekley23]

DontTalk is correct, in any case.

 

[Kepekley23]

The OBD calc makes the mistake of using the nuke calculator to get the feat's yield.

 

[Mand21]

Why do we use the Near Total Fatalities area rather than the Widespread Destruction area, btw?

 

[WeeklyBattles]

So the yield for a standard surface wipe should be the bayonetta calc?

 

[Spinosaurus75DinosaurFan]

I'm pretty sure we can calc surface wiping with KE.

 

[Kepekley23]

@Mand

Widespread destruction doesn't cover enough overpressure to destroy most structures within the blast radius.

@Spino

This is for a standard, timframeless surface bust.

 

[Spinosaurus75DinosaurFan]

Okay.

 

[Golden_Void]

Kep's is fine.

 

[Spinosaurus75DinosaurFan]

Agreed.

 

[DarkDragonMedeus]

Kep's suggested calc looks good to me as well.

Has Kepekley's calculation been posted in a blog format?

Does this nerf MCU!Thanos, or does Thanos actually have evidence of moving the atmosphere?

 

[Kepekley23]

The clouds are seen parting on an intercontinental scale.

 

[Kepekley23]

And, even then, the feat happened near ground level so the energy of the clouds being parted with Inverse Square Law taken into account would likely still yield a 5-A result.

Average Elevation of Earth: 840m

Earth's Area: 5.10100e17 m2

So we get 4.28484e20 m3.

So the results are:

Fragmentation: 3.427872e27 joules (819.2810707457071 petatons)

Violent Fragmentation: 2.9565396e28 joules (7066.299235181724 petatons)

Pulverization: 9.18455454e28 joules (21951.61218929279 petatons)

Vaporization: 1.10120388e31 joules (2631940.4397705845 petatons)

Atomization: 1.32196741e31 joules (3159577.9397705905 petatons)

Subatomic Destruction: 2.31509905e40 joules (5533219526768705 petatons)

We always need to post useful calculations in a blog format, so we have something to link to.
