Boros’s Kick to the Moon Calculated

Boros is probably one of the most absurdly over estimated characters in One Punch Man, and of his many feats that are praised like some sort of god, his moon kick is definitely near the top of that list. So we are going to calculate it so that people can stop worshiping its theoretical potential and see it for the feat it is.

From the time that Saitama leaves Boros's knee to the moment he hits the moon, only 2.92 seconds pass. Using the average distance between the moon and earth,384,400 km, this puts this attack at 294 million Mph or about ⅓ the speed of light. Taking Saitama's weight and solving for relativistic kinetic energy we get a result of 169 megatons of TNT. However, it takes about .15 seconds for this attack to get up to speed yielding an acceleration of over 877 million m/s^2 and a force of 61 billion newtons. Displace this to the moon and we get a power of 5.655 gigatons of a TNT. Leagues more powerful than just using the Kinetic Energy, but still abysmally low tier for the universe Of One Punch Man. In fact, I would bet money that Garou’s centipede feat is several times more powerful.

Hope you continue calculating more feats from OPM

Could we get reasonably higher estimate if we assumed that Saitama was sent there faster than how the anime portrayed it? At least based on latter feats even lower tier monsters have relativistic to FTL scaling from dodging attacks like Genos’s lasers.

A couple problems with this. First of all, you forgot air resistance. Normally, air resistance is not that important, but when firing a non aerodynamic object a sea level at 33% the speed of light, drag is HUGE. I'd be surprised if it didn't set the atmosphere alight. 
Another thing is that boros did not actually take ~1.5s to transfer the energy. The knee you calculated is obviously a slow-mo/freeze frame. It makes absolutely no sense to assume that the two characters being stationary in the air for 1.5 is real time. There are tons of punches and kicks in Boros' fight which are slow-mo. In reality, given how fast boros is travelling before hitting saitama, the transmission of momentum is probably close to instant.

I ran the calculations and 1 kick from Boros could destroy Neptune low balling

[scrumt]

I’ve only seen him downplayed. There is a guidebook statement of his collapsing star roaring canon being star level.

[DaimaTa]

Can you calc red roc it turned a huge rock to dust to glass from miles away I just wanted to know the sheer heat and power from it

[Xslayerdoom]

I think that kick is way faster than 2 sec because they needed to slow the animation a bit so that we could see the kick of boros

[yamato]

Let's not talk about Saitama being able to run backwards extremely fast

[loercayt]

You forgot the part where he shattered the moon

[mikhailmaximorf]

It's not 877 million m/s²! That's 87.7 million m/s²!

[Goji-Moji]

So you uh, don’t understand force and acceleration, huh?

[Jinwoo]

Bro can you calculate garou grb caz its solar system level by calculation caz massive star is supernova which size big as 10 suns and narrative said its stellar explosion which means supernova or hypernova but logic only connect to supernova which is massive star

[christopherbaker]

You are incorrect with the speed of the attack by a factor of at least five. Using the most conservative logical figure for the acceleration time would put the speed of Boros' attack at 758, 319, 503 mph.
As acceleration time approaches zero the power approaches infinity. So you being extremely extremely off in the acceleration time will completely neuter and tank the power level.

[dragfang]

Hey check out and calculate these mangas feats mushibugyou, ayashimon, undead unluck and radiant

[Jimbo_nill]

I like how 2 of the panels he shows doesn’t even require 5.6 Gaston’s to do that

[javiereduardocarrillocastr]

Force and potential energy no longer apply when Saitama leaves Boros leg.

[christopherbaker]

F = m*a
F = kg * a
F= 80 * v/s
F= 80 * ((distance to moon/travel time)/acceleration time)
F=80*((384.4m meters/2seconds)/(time span of kick)
F=80*((384.4m meters/2seconds)/(time it would take saitama to travel from point zero to end of boros' kick (~2meters). Average velocity of saitama between points would be half of final velocity (96.1m meters per second). 2 meters/ 96.1m meters/second = travel time between points.
F= 80((384, 400, 000/2)/(2/96, 100, 000)

[christopherbaker]

You got the acceleration wrong my guy. It can't be that low across the span of a kick, i mean, look at the animation lol, its clear it wasnt smooth. You definitely low-balled that acceleration, and that's why you are getting such a low number. As t approaches 0 force approaches infinity in the calculation.

[actuallynotphyto]

Bro slow down you talk too fast and you aren’t saying actual words. For the love of God please annunciate your words

[christopherbaker]

An actual conservative acceleration time would actually be seconds... not 0.15 seconds. Why?
Because of the way the physics works, my guy. When acceleration begins and when acceleration ends the average speed the average speed must be half of the final velocity.
That's just the way the physics works my guy. The span of the kick is 2 m at most. You can't just kind of look at the animation. Be like oh, looks like it's 0.15 seconds. You really think that kick happened in real time? It was obviously slowed down so people like us could see it my guy. That's what you would say if it was dragon Ball Z right? Or dragon Ball super? Come on.
