Would there be a difference if we voting slowly, one by one?
Nothing noticeable. Eight billion people times 100kg average mass, divided by 360 million square kilometers of ocean surface equals 2222kg/square kilometer. Or, assuming the density of a human being 1g/cm^2, a
2.22mm0.00222mm height difference. Ah, the joys of metrical calculations.EDIT: Steve pointed out that I was off with my density calculation. Thanks for the hint, coffee was obviously not yet working…
Per XKCD, nothing significant would happen. Even if all the people were standing in roughly the same area, the Earth would be moved by “less than an atom’s width.” If people were spread out randomly across the Earth, all the forces effectively cancel, and even less happens.
But that’s everyone jumping on land, not into the ocean.
Oh, jumped IN at the same time. I missed an important word there.

Could you explain this sentence like I’m dumb?
Probably “went in” before a missing space and an autocorrect turned it into “voting”.
I assume they’re using voice to text and meant to say “go in slowly”
If 8 billion humans displace 50 gallons each, thats 400 billion gallons. The volume of all oceans is about 1.5 billion cubic kilometers, which is 3.96258e20 gallons.
Eh, I got tired of trying to do that math, but thats a big frickin difference. I dont think the sea level rise would be measurable.
Try metric, it is way easier. The change will be about 2mm, whatever that in elephant heights or whatever is.
How did you arrive at that number? It’s an entire SI prefix away from the estimate I got in a sibling comment, so I assume one of us has something wrong.
Edit: oh I see your other comment with the working. I think you may have the density wrong; if a density of “1” is in kg/m³ it’s way off – the density of water and approximately-humans is usually given as 1 kg/Litre.
Yep, you are right, with ‘density of 1’ I meant 1g/cm^2. Which is indeed off.
50gal is quite generous; average adult weight estimate tops out around 80kg and that doesn’t account for children. Divided by approximate human density 1010kg/m³ gives 0.08m³ or around 21gal. Multiplying that by 8 billion humans and dividing by the ocean surface area of around 361000000 km² gives approximately… 1.8μm of sea level rise.
Hey that gives rise to a new shower thought. If you blended all humans and spread them out evenly across the earth, how many atoms thick would the layer of human be?
Actually, I’m a physicist from the world famous ETH in Zürich Switzerland, and my team and I have been working on exactly that question for the past five years! We have created an exciting theoretical model (manuscript has been submitted to PNAS, in second round of corrections). We are now focusing on a series of experiments to substantiate our theoretical findings. Alas, Switzerland is a notoriously landlocked country, due to which such experiments are hard to realize. In addition, strict nudity in public laws apply. As a result, all our grants were canceled, and we are now unemployed.
I hope that you could at least all be nude while doing all that research work in your dark basement offices there beneath the mountains…
Splash.
Have you calculated this before? You came up with an answer awfully quick.
Checks out
There’d be a lot of piss mixed in.
We would literally never know.
the planet Earth has a mass of 10²⁴ kg (source, Wikipedia), all humans together have a mass of 10¹² kg (source: do the math. 10 billion person · 100 kg/person). make of that what you will.
12 out of 24 — wow, so we are quitte close to absolute majority!
