We are aware that the idea of making a sticky ball of flesh from all the people on earth sounds crazy. A ball of 7.88 billion people!
As you read the article, you probably had a ball of extraordinary size in your mind. However, in the continuation of the content, you will realize that this interesting meatball is not as ambitious as you think. If your calculators are ready, let’s get started without wasting time.
How many people can we fit in 1 cubic meter of space?
First of all, how about we start by refreshing what we remember from physics and chemistry classes? We know that density or density means the amount of matter per unit volume (provided, of course, that other conditions, namely temperature and pressure, are within certain standards). So what is the density of a person and where will this information be useful for us?
The human density in one cubic meter of volume is 985 kilograms. In other words, we can say that the density of a person is 985 kg/m³. You may have noticed that it is approximately close to the density of water. While we are solving physics questions, rounding the density of water to 1 gr/cm³ is a relief for us in terms of processing intensity, but we will not do the same here.
We’ve done the density part, now let’s take a look at the mass side. Assuming the average person weighs about 62 kilograms, you can fit 16 people mixing in a giant blender into 1 m³ (But of course you shouldn’t try!).
When we want to calculate the area to be covered by 7.88 billion people in the world, we can reach the result of 496 million m³ with a small multiplication. In other words, we can fill all people on 496 million m³.
So how can we visualize this greatness?
If we think about the Eiffel Tower, which is the apple of the eye of Paris, which is 300 m long; The sticky ball, made up of all the people, is about 3 Eiffel Towers tall. In addition, this human ball is large enough to easily enter Central Park in New York.
Moreover, it is not the first time that one thinks of calculating this. In 2014, when the population was relatively small, these crazy mathematical operations were also done. Considering that the world population was 7.159 billion that year, it was concluded that the round giant structure was large enough to easily enter the Grand Canyon in the state of Arizona.
How much can the size of this giant meatball change after 1 year?
We can predict the world population in 2023 with a simple calculation. We’ve estimated how much the world’s population will increase next year by multiplying the current population by 1.0105, so far, all right. But how much will our sticky ball be affected?
As the number of people increases, the volume of our ball will naturally increase. He turns back to our high school knowledge to calculate how the radius will change. Our physics teacher said, “The radius is directly proportional to the cube root of the volume.” We remember the expression. So, the giant human ball with a radius of 500 meters this year will likely be within a radius of 501,743.9 meters next year.
As a result; Together we built a giant ball that could fit billions of people of different ages, genders or occupations, and we realized that we weren’t actually as big as we thought. And where else can you think of that sticky ball of people could fit in?
