I enjoyed the water-sphere thread so much, I decided to run the math to see how big of a meatball we could make with all of us, and the result is
The numbers I used:
density of ground human = 950kg/m^3 (assumed same as ground beef)
average mass of adult human = 54kg (picked the low-end since we're not all adults. The average mass of "all humans" would undoubtedly be somewhat
lower, so I'm fudging on the high side)
number of people = 7,016,000,000
We would make a 913m diameter meatball. Somewhat less than a kilometer.
I double-checked my math with Solidworks by constructing a sphere and measuring it's volume, so I know it's right.
Here's a picture of us all, call it a human family portrait, visiting Washington DC.
Surprisingly small we all are, aren't we?
