If a Tyrannosaurus rex were released into modern times, how many people would it eat every day?

How many people do you have to eat a Tyrannosaurus rex in New York every day?

Don't scold me! The question of this day kill is not something I came up with, if I see the end, I will tell you. This question is very, very big and challenges people's fragile nerves, but the answer is absolutely unexpected.

Tyrannosaurus rex is the ceiling of the dinosaur world, and the last glory, this guy appeared only 2 million years ago, was destroyed by an asteroid "boom", and dragged down all other dinosaur species - except bird dinosaurs, probably heaven's punishment for their gluttonous appetite.

Without further ado, if someone really went to the Cretaceous period to catch a Tyrannosaurus rex and dragged it to New York to release it, how much would it have to eat in a day? Don't scold me! It's not that I'm unfriendly to the American people, see the end you understand.

Many people may scratch their heads, but it's very simple, we just need to know how many calories of energy the Tyrannosaurus rex consumes per day. However, Tyrannosaurus rex has been extinct for 65 million years, and the people who go to catch it probably can't manage so much, how can we know how many calories it eats a day?

A simple way is to compare it with modern animals, Tyrannosaurus rex weighs about the same as modern elephants, so it should not consume many different calories, a best guess is about 40,000 calories.

It's not very simple, just need to calculate the number of calories in people, but this question may be unpopular in Chinese environment, because it seems to challenge the fragile nerves of many people, so I did not find a more reliable answer.

But in an English-speaking environment, I found a study by James Cole, an archaeologist at the University of Brighton in the United Kingdom, but he may also be worried about hurting public nerves, and studied the heat energy value of the human body by preying on each other by ancient humans.

Without further ado, Cole's research shows that the human trunk and head have 5419 calories, the thighs have 13355 calories, the heart has 651 calories, the brain, spinal cord and nerve trunk contain a total of 2706 calories, in total, the whole human body contains about 125822 calories, while the mammoth at that time was 3.6 million calories, which can feed 25 modern people for 60 days.

So the answer is also about to come out, release a Tyrannosaurus rex to New York, and one person can feed it for 3 days.

Isn't it a big surprise? Where? Tyrannosaurus rex 3 days to eat a person? This is so unscientific, so how can it be said that it is gluttonous? It's pretty showy, okay? Gentle, chewing slowly, eating very elegantly, Spielberg came out to walk two steps? Why wronged the Tyrannosaurus rex!

This brain hole is actually from Randall Monroe's new book "What If 2", and the 7th question is: If a Tyrannosaurus rex were released in New York, how many people would it need to eat every day to meet its energy intake?

So the American people can't blame me, it was Monroe who released the Tyrannosaurus rex to New York, but he based it on another number, an 80-kilogram person has 110,000 calories. He found that 115,000 people were born in New York in 2018, which could feed about 350 Tyrannosaurus rex.

Is this out of your brain, Tyrannosaurus rex has such a small appetite and such a large human population, how can it feed a mere 350 Tyrannosaurus rex? This is that you don't understand the concept of sustainable farming, you can't eat up the old mother and child, the more you eat, the less. So Monroe's Tyrannosaurus rex probably knew how sustainable it was, just eating as many people as were born each year.

Another even more surprising knowledge point is that the average McDonald's restaurant in the world can feed 12 Tyrannosaurus rex just by selling hamburgers every day!

There are many more weird brain holes, so you may wish to buy a copy of "What If 2" to read for yourself, which is used to tell bedtime stories to children, and it is a great choice to develop brains from an early age!
