What do you mean mechs are non-credible?

I had never heard of the Square Cube Law 🤔 This is what I found:

"The Square-Cube Law states that for mechs, scaling up in size increases their volume (and thus weight) by the cube of the scaling factor, while their strength and surface area increase by only the square of the scaling factor. This means a mech that is twice as tall, wide, and long would be eight times heavier but only four times stronger, making it far more prone to collapse under its own weight and limiting how large mechs can realistically be built without becoming structurally unsound."

A mostly-hollow mech with a graphene exterior would allow for a volume of significantly less density than the surface area.

Suck it, square cube.

Yeah everybody said the same about directed EM energy weapons and the inverse square law, and then: fuckin lasers.

Square cube law only dictates that better material science is needed in the build process.

There is a reason an Airbus A380 isn't built out of stainless steel.

Balsa wood mechs when?

Better option: create a race of tiny little people. Lilliputian style. Help them built lil cities.

Now you're a Kaiju.

it just means you can't scale them up. doesn't mean you can't design them with the size in mind. just remember to make their feet big enough to not instantly sink all the way into the ground once they go off road 😄

I mean, it seems to me mechs are more outlandish because anything vertical doesn't do as well in the whole, 'even halfway stealthy' class.

Shut up about the square-cube law! I want the big robot just like in my japanese animes!
