Although the "Godzilla: King of the Monsters" movies are science fiction, have you ever wondered why Godzilla doesn't exist in reality, or why there isn't any creature on earth that fanciful?
While the height of the latest Godzilla in the series of these films is 119 meters, the largest known animal on Earth is the blue whale, a marine mammal that grows up to 30.5 meters in length, and can weigh 200 tons, which is only a quarter of the size of Godzilla .
As for the largest land animal - according to the article published in the "Science Alert" website - it is from the tree of the dinosaur family and belongs to the "Sauropod" branch, which are huge quadrupeds with a long neck balanced with a long tail that can exceed 40 meters and weigh 70 tons, If not more.
The heart can't stand
It is biologically impossible for any organism to grow close to the size of Godzilla in real life, according to a Business Insider article, citing Mike Habib, a paleontologist at the Natural History Museum in Los Angeles County, and an expert on giant reptiles. Who also helps design fictional creatures for TV and movies.
This is due to several reasons:
Godzilla's brain will die in real life long before he gets anywhere;
Because his heart simply isn't big and strong enough to pump blood to his head.
The heart should occupy almost the entirety of the chest cavity, and this would not leave much room for the rest of the other organs.
Very large animals on Earth - such as titanosaurs - got around this by walking on four legs and with their heads raised in front of them, not up.
With this head position, they don't have a great need to pump blood against gravity.
In the case of Godzilla, she walks on two legs, and her head is up, and this requires huge amounts of energy to push the blood from the heart to the head, but even if Godzilla crawls through cities everywhere, and he is not erect, he will face another problem, which is movement .
For Godzilla, it will take more than a full second for nerve signals to travel along his body (Shutterstock)
nerve signals
You can only raise your leg or arm because your brain is firing signals to the nerves in the muscles in your leg and arm.
These signals travel at a speed of about 100 meters per second;
Thus, the message from the brain to the man is almost instantaneous.
For Godzilla, it would take more than a full second for the nerve signals to travel along his body;
Thus, his nerve conduction velocity will be so slow that he cannot move.
Hence, it would take a very long time to do anything.
It is true that Godzilla appears to be very slow in the movies, but in reality, it will be much slower than that.
In this case, finding prey to eat will be very difficult, so that he will prefer to avoid exerting effort and speed to catch it;
Thus, Godzilla would not have enough energy to power such a huge core.

Get heat from the sun
But even if Godzilla could overcome the movement problem, he wouldn't have time to fight enemies or demolish buildings;
Because he will be busy lying in the sun and getting sunbathing to warm himself.
All animals need a way to regulate their body temperature, and reptiles and other cold-blooded animals stay warm by sunning;
So if Godzilla is a reptile, he has to spend all his time lying in the sun.
The heat of the sun needs to be transmitted through meters of tissue to penetrate his skin and reach his internal organs, in order to remain warm;
Thus, he must spend hundreds of hours in a row sunbathing in order to feel warm.
But what if Godzilla was more like a mammal?
In this case, he would not need to rely on the sun because warm-blooded creatures produce their own body heat.
Unfortunately, this can cause another problem;
Because Godzilla is so large, and its core temperature will reach 300 degrees, it will probably cook itself by itself in this case.
And even if Godzilla in real life could somehow overcome all these problems, his skeleton would collapse under his weight.
At 90,000 tons, Mike says, this skeleton isn't strong enough to support all that weight.

How do the largest animals on Earth feed?
Sauropods found an effective energy-saving scheme. They made good use of their plant-based diet, allowing their spinning head to roam around in search of food while keeping the bulk in place.
Whales have also perfected this strategy over the past tens of millions of years, essentially becoming long swallow tubes for plankton death.
Thanks to the sea water, the whale bones survived the shock of carrying all that mass.
Ultimately, to grow truly massive, we'll need a world where gravity is low, the oceans are deep, or the atmosphere is thick.
We'll need a calorie-dense supply that's on hand and effortless, and we might even need an entirely new way of imagining how to move vital materials around that mass.
