You could also (in theory) put every human on Earth in Texas with a population density of only 26,000 people per square mile, about the same density as New York City.

I read you could pile all the 5 billion human bodies on earth in a pyramid and it would only be 1 km square base.

That's nothing, I swear the entire planet squeezes into a mile long stretch on 93 in Boston every weekday around 5:30 pm.

I'm pretty sure that one crosses a comfort vs density threshold.

If you removed the empty space in our atoms, you could fit all humanity into a unit roughly the size of an m&m.

If it's an equilateral square pyramid, the volume would be about a quarter of a cubic kilometer. If we assume humans have an average mass of 65 kg and the same density as water, that gives us room for just under 4 billion humans.

Err, there are over 7B people on the planet right now.

And that's only the living people, we got lots of dead human bodies lying around, too!

The 5B mark was ~1987 according to wikipedia's population numbers in 1985 and 1990.

Embiggen the pyramid a little.
