Discover the Surprising Size of a Meatball Crafted from Humanity—You Won’t Believe How Small It Is!

What if we could squish every person on Earth into one solid sphere? It sounds like something from a sci-fi movie, but a mathematician recently explored this idea on Reddit. His calculations show that the total size of such a sphere is surprisingly small, changing how we think about the sheer number of people.

To start, the average human weighs about 62 kilograms. With a density of roughly 985 kilograms per cubic meter, about 16 people could fit into one cubic meter if packed tightly. Given the current global population of around 8.2 billion, that’s about 516 million cubic meters of mass.

When he crunched the numbers, he found that all of humanity could fit into a sphere with a diameter just shy of one kilometer. To put that into perspective, that’s about three Eiffel Towers stacked on top of each other. Interestingly, this mass could easily fit in Central Park in Manhattan, which covers around 3.41 square kilometers.

### Evolving with Population Growth

What’s even more interesting is how this sphere would grow with the population. Currently, the world’s population increases at about 1.05% each year. Using this rate, the sphere’s radius would expand by around 1.74 meters a year. This slight growth reveals how densely packed humanity can really be while still showing that even as we grow, the sphere size increases modestly.

### Historical Perspectives on Humanity’s Size

The idea of crunching humanity into a physical form isn’t new. Back in 2014, Michael Stevens, known for his educational YouTube channel Vsauce, shared an image showing how all 7.2 billion people then could fit into the Grand Canyon. The graphic highlighted that even a massive geological feature like the Grand Canyon would still have plenty of space left over with all of humanity packed inside. This kind of visualization helps us grasp numerical data in a much more relatable way.

### Current Trends and Insights

Social media reactions show a mix of amazement and curiosity when people encounter this concept. Users often share the visuals, and many comment on how it reframes their understanding of the world’s population. One recent trend on platforms like Twitter involves comparing the sphere with various landmarks, sparking discussions about density, space, and urban planning.

The insight from experts in various fields also adds depth to this discussion. For example, demographers note that as population density increases, urban areas may face new challenges in infrastructure and resource management. Comparisons that bridge the gap between abstract numbers and physical reality can provide a new lens through which to view our growing world.

By visually compressing humanity, we can better appreciate the magnitude of our existence. Summing it up through relatable measurements and comparisons strengthens our understanding of how we fit into our world—both literally and figuratively.
