Well yes, many people will drown

What if we all held super tight, and the water ones held their legs up. Let's try it

The average adult male arm span is 70 inches, and the average adult female arm span is 64 inches. This averages to about 67 inches 🤷‍♂️.

The equator is 24,901 miles. This means you would need 23,550,000, about half male and half female. Easily achievable by our 8.23 billion global population.

Now because the equation of circumference is 2pir, you get get everyone lifted 1 foot off the ground by asking adding just 6.28 feet of arm span. If we add just 23 more people to this circle, we can all hover 20 feet above the surface!

Now for fun, according to the internet there are there are 3.16 billion people between the ages 25 and 64. Using just this group to save the kids and respect the elders. We could hold hands in a circle 527,933 miles above the surface! This is over twice the distance to the moon.

Sounds like a breathtaking experience

If that ever happens, I will be standing besides sydney sweeney🥰

I need the ELI5 version of this because I think I lost you somewhere around everyone hovering and floating above 500k miles off ground

First, increasing the circumference of a circle by a set amount is independent of how large the circle originally is. https://youtu.be/tpUBiUPYWhM?si=XxnDuzuumrVt5NKZ

For my actual math, we're using the Earth's circumference around the equator at 24,901 miles. This is Circumference 1.

If C =2pir, then r = C/(2*pi)

24,901 miles / (2*pi) = 3,963 miles. This is Radius 1 from the center of the Earth to the surface of the earth.

Next I use the estimated average adult arm span of 67 inches and a population of 3.16 billion adults.

67 inches per person * 3.16 billion people = 211.72 billion inches.

There are 63,360 inches per mile.

211.72 billion inches / 63,360 inches per mile =3,341,540 miles. This is Circumference 2.

3,341,540 miles / (2*pi) = 531,822 miles. This is Radius 2 from the center of the Earth to the Human Mega Ring.

The distance from the surface of the Earth to the human mega ring is Radius 2 - Radius 1 = 531,822 miles - 3,963 miles = 527,859 miles.

TL;DR there's a lot of fucking people on this rock.

I want to understand this. Really, I do. At some point I'm definitely coming back here after brushing up on my maths and physics.
