StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

No, it's physically impossible, right?

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

Well, the scaling of volume and surface area and height, right, goes at different powers.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

Mathematical powers, not physical powers.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

Well, that kind of too, right?

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

So if I increase, if I double in height, I'll actually increase by a factor of eight, right?

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

in volume, right?

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

Two times two times two, length and width and height.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

So I would be eight times larger in volume.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

And thus, presumably all of the stuff inside me is made of the same material.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

I'm eight times heavier.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

That means my legs have to support eight times the weight, right?

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

Now, if I get bigger, it gets worse.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

If I'm 10 times taller and wider and thicker,

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

then I'm a thousand times more massive.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

My legs are increasing in surface area, in cross-sectional area, only by a factor of 100 in that case.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

So my bones have to be 10 times stronger to support my weight.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

That's absolutely right.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

So if Godzilla being 400 feet tall or so in the first movie.

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

Yeah, so much that all known bone would shatter, right?

StarTalk Radio
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu

All known muscles would tear.
