Density question

[Golden_Void]

Does durability correlate with density? For example, cinematic Bruce Banner is probably average human with regards to density, but Hulk can have bullets bounce off of him and be unaffected by explosive ammunition. If so, is it a quantifiable increase?

Nah it doesn't. For example, titanium is more durable than iron but the former is heavier

In terms of fiction though, like Luke cage has super hard skin which not even a normal metal drill (except for the Judas bullet) and a needle couldn't pierce his eye iirc.

Fiction does some times treat density like being proportional to durability.

Like Stitch or Asgardians being denser than humans thus stronger and more durable.

Though since this isn't the case with real materials i wouldn't treat it as a general rule.

Seems like it could be unquantifiable then. If I was trying to find the density of the hulk since it's obviously greater than a human's, I wouldn't be able to do so then it seems.

I don't know about density. But Savage Hulk's official weight according to Marvel is 1040-1400 pounds. And we've accepted using this weight for calcs. If that helps somewhat.

One place I checked suggested using the density of lead as a minimum.

Then I saw a Nerdist video that suggested Cage doesn't have a higher skin density, because that would just add to his skin weight, not skin strength.

He used an 8g, 9mm diameter bullet at a velocity of 360m/s, and said if his skin is bulletproof, then the bullet should stop before it travels through 2mm of skin, so he assumed the bullet doesn't pass the thickness of a hair, 0.05mm in 1ms.

So the formula for Cage's skin strength was proposed as:

Ls (luke strength) = (8g*360m/s)(1/0.001s)/(9mm*pi*0.05mm)

Which gives 2.037GPa (gigapascals) or 2.037e+9 N/m^2

At least. Kevlar measures in at 3.62 GPa.


I still like the first idea. :/

I would take such videos with a grain of salt.

I've seen so much bullshit from youtube videos trying use "science" to explain how powerful characters are.
