A Mathematician Calculated The Size of a Giant Meatball Made of Every Human (sciencealert.com)

(Wednesday June 11, 2025 @03:00AM (BeauHD) from the food-for-thought dept.)


A mathematician on Reddit calculated that if all 8.2 billion humans were blended into a uniform goo, the resulting meatball would [1]form a sphere just under 1 kilometer wide -- small enough to fit inside Central Park. ScienceAlert reports:

> "If you blended all 7.88 billion people on Earth into a fine goo (density of a human = 985 kg/m3, average human body mass = 62 kg), you would end up with a sphere of human goo just under 1 km wide," Reddit contributor kiki2703 wrote in [2]a post ... Reasoning the density of a minced human to be 985 kilograms per cubic meter (62 pounds per cubic foot) is a fair estimate, given past efforts have judged our jiggling sack of grade-A giblets to average out in the ballpark of [3]1 gram per cubic centimeter , or roughly the same as water. And in mid-2021, the global population was just around 7.9 billion, give or take.

John Brunner's 1968 novel [1]Stand on Zanzibar [wikipedia.org]

The title is an allusion to a thought experiment in which it was calculated that all the human beings in the world could fit shoulder to shoulder on the Isle of Wight; given population growth, Brunner expanded this to the island of Zanzibar.

Does Central Park (assuming NYC) have a "volume"? I looked it up and it's not 1km wide, but it's longer than 1km long, so how does this 2D rectangle to 3D sphere comparison work?

The article has a picture. The edges of the meatball stick over the edge of the park, but only once you get to an altitude higher than the surrounding buildings.

7.88 or 8.2 billion?

And more importantly, how long at what heat (gas or electric oven) for the meatball to be well done?

Can someone do a visualization of humans getting dumped into a grinder over Central Park and forming into a meatball?

Yeah, right, everyone knows that what mathematicians do is do trivial arithmetic on their pocket calculator. And Reddit is well-known for being the primary place where mathematicians publish their research results. :-(

Did this mathematician consider the impact of the breadcrumbs on the weight and volume of a meatball? Or is he doing calculations for a "bad" meatball? Hmm, meatballs made of humans. Definitely a "bad" meatball.

Similar calculation (Score:2)

I did a similar calculation for oil. If you collected all the unrefined oil consumed by the United States in one day into a cube what would it look like? I no longer remember the exact figures, but a visual in my mind is clear. Imagine a 100 yard football field in the US. The cube is hovering above the field: a huge black mass of oil. The cube would be roughly 40% larger than the end zone lines.
