That roar belongs to one of the most iconic movie monsters of all time:
Since his debut in 1954,
the King of Monsters hasrampaged
比如东京 纽约以及大阪 这还只是一部分
across Tokyo, New York city and Osaka to name a few.
And over the years, he’s gotten bigger,
The latest Godzilla is a record
119 meters tall,
about six times taller thanthe tallest animal in history.
And to be fair, it’s a fantasy film,
not a nature documentary.
But just how fantastical is a three-six-story tall,
lizard-dinosaur creature who breathes beams of atomic energy?
Well, energy beams aside,
Godzilla is actually even more unrealistic in my think.
The real reason Godzilla could never get that big
Now, earth is no strangerto enormous animals.
Just look at the largest dinosaur: the titanosaurs,
or today’s blue whales,
which reach up to 30 meters long
and can weigh 200 tons.
与它们相比 哥斯拉似乎也不是不可能的 对吧？
Compared to them, Godzilla doesn’t seemthat impossible, right?
Mikes Habib: These critters aremassive on a scale that’s just totally impossible.
I mean, assuming, at least, they’remade of anything, even remotely like what we’re made out of,
and follow any of the rules of biology.
they are, they are completely impossible.
That’s paleontologist Mike Habib,
He’s an expert in giant reptiles.
and also helps designfantastical creatures for TV and film.
And according to him,
a creature like Godzilla could never exist in real life
for multiple reasons.
First, he would be brain-deadlong before he ever reached a city,
because his heart simply isn’t large and powerful enough
to pump blood to his head.
Mike Habib: His heart would haveto be thousands of tons
and fill most of his chest.
You’d have to have vessels that you could drive a car through,
And, and he, you know he would, you know he needs the energy consumption of a small power plant,
probably every minute in order to run it.
Of course, he’s nuclear-powered,
so maybe he has the energy to spare.
large animals like titanosaurs got around this
四脚着地走路 同时头是往前伸 而不是竖着抬起来
by walking on all fours with their heads held out in front them, not held up high.
That way, they don’t have to pump blood against gravity as far.
But even if Godzilla did crawlacross cities on all fours,
he’d have another problem: movement.
You see, whenever youlift your leg or arm,
it’s because your brain firessignals to the nerves in your leg and arm muscles.
The fastest of these signals travel around 100 meters per second,
so the message from brain toleg is virtually instantaneous.
Not for Godzilla though.
It would take more than a full second for nerve signals to travel the length of his body
Now, a second still sounds pretty quick,
but in reality…
Mike Habib: His nerve-conduction speed becomes so slow
that he can’t move,
takes forever to do anything.
Now, Godzilla does look pretty sluggish in the films,
but it turns out, in reality, it would look more like this.
But even if Godzilla could move super fast,
he wouldn’t have time to fight enemies or demolish buildings,
because he’d be too busy sunbathing.
All animals need a way to regulate body temperature.
Reptiles and othercold-blooded animals stay warm by basking in the sun.
But in Godzilla’s case,
heat from the sun would have to travel through meters upon meters of tissue
to penetrate his hide and reach his internal organs.
So to stay warm,
he’d have to spend hundreds of hours’ straight sunbathing.
But what if Godzilla were more like a mammal?
He wouldn’t need to rely on the sun,
since we warm-blooded creaturesproduce our own body heat.
But unfortunately, that would cause yet another problem.
Mike Habib: But then he’s so big, he probably cooks himself.
His core temperature hits 300 degrees.
And even if he somehow gotaround all these problems,
his skeleton would stillcollapse under its own weight.
Now, Mike says he’s awhopping 90,000 metric tons,
and that skeleton’s just not strong enough to support 90,000 metric tons of, well, anything.
Mike Habib: Yeah, he would just crumple.
He’d be a very large pile of meat.
Not a very intimidating picture.
In the end, Mike says Godzilla could only be about half as tall as he was in the original film
before his poor heart would give out.
But just because Godzilla’sbody is unrealistic
doesn’t mean it’s bad.
In fact, he’s perfect for the role.
He’s tall enough to stalkpast city skyscrapers,
which give us iconic scenes like this.
Mike Habib: Just straight-up magic in themodern world setting,
and just go and enjoy itas such.
