Chainsaw Man discussion thread

I can physically demonstrate that large strands of hair have a higher terminal velocity than 5 centimeters per second in front of my own face. Even if those papers you reference really did exist, their credibility can be disproven right at home. 5 - 2 centimeters per second is an absurdly slow terminal velocity. The top speed of a sloth is 8 centimeters per second, for reference.

  • Assuming Yoru's mouth is open at the typical max mouth opening (5.2 cm) for adults for the largest timespan possible-
  • Yoru's hair fell (5.2/67 * 87 - 5.2/67 * 63) = 1.862686567 cm
  • Solving backwards for time w/ Earth gravity acceleration, 0.01862686567m = 1/2 * 9.80665 m/s^2 * t^2
  • sqrt(0.01862686567 * 2 / 9.80665) = t, t = 0.06163459568 seconds
  • 29,171,580 meters / 0.06163459568 seconds = 473,298,797.2 meters per second, or 1.578754851c, FTL.
  • This makes Kinetic Energy impossible.

Not terminal velocity. I'm using initial velocity, and air drag is instant because it's hair so you can't use the normal formula, view my recalc

because the speed for hair falling was taken from chatGPT, it has a source of a real article
Not necessarily, Chat GPT makes up sources all the time. (Court Case where a lawyer used Chat GPT, and ended up referencing previous cases that Did Not Exist)
Cross-sectional area (A): Average diameter of 50μm=5×10^−5m.

A = pi(diameter/2)^2 = pi(5x10^-5/x)^2 = 1.96×10^−9 (m^2)

Mass of a single strand of hair (m): 0.62 to 0.78 milligrams or 6.2x10^-7 to 7.8x10^-7 kg
That's how fast a single individual hair will fall, which will be much slower than a clump of hair thanks to the higher surface area to volume ratio. A clump of hair is the thing being measured though, which falls much faster. Always fun to see someone using the drag formula though.

Also late reaction but-
You cannot be serious when you tell me that a dude who isn't even a Vice Captain of Public Safety, who ISN'T IN THE SPECIAL DIVISION, is tougher than a Hybrid.
So true dude.
Not gonna lie, this was the best possible response to that argument. I was actually dumbfounded for a few seconds trying to come up with a counterpoint.

I could try to do a recalc (or just buy a cosplay hair home and experiment on it). I'm 100% sure that air drag would reduce initial velocity significantly though, it shouldn't go past light speed. But anyways, the hair still suggest an extremely tight timeframe, so either just assume a tighter timeframe (0.1 second or something) or go through hell like how I'm doing.

Man, should've went with super lazy assumption.

The bullet moved over 29,000 kilometers in the time it took something to fall about 1.86 centimeters, if that's used as a basis. It's very possible that it went FTL Even that generous tenth of a second you posit would result in the bullet going 97.3% c, just barely under the bar.
 
That IS from 2023
Still wouldn't hire an AI Lawyer.


Anywho, the current problem I'm seeing with using standstill-Yoru as a reference is that she’s actually at slightly different angles in the two different panels, on top of one being from up close while the other's from afar (meaning more/less dramatic parallax which is why her hand is so much bigger in the close up shot because it's closer to the POV than her head is while it's less exaggerated in size in the shot taken from farther away) which I noticed when trying to line up their faces in paint.net, meaning her hair could've moved more or less relative to her face but not in a way that's apparent thanks to the slight change in perspective

is the calc really about the hair???

Bro now I can't get it out of my head anymore

0.1 second confirmed, or maybe just reduce the timeframe cause 2 seconds is too much for this case, the hair calc is so real.

Also ultra refined calc coming, I'm sure 100% that it will be within the range.
