# Science questions

So after realizing that the other sections of gearbox forums are not really ment for me to post in and half of my posts get flagged, I just decided to complealty give up on it and ask my homework questions so I don’t have to do the work

How much does the sky weight?
How Much Does the Earth Weigh?
And how much do all people on earth weigh combined?

You’re assuming too much.

Worth a shot, no?

The earth is flat, so it doesn’t weigh as much as you might think

So do I only calculate the mantel or what about the space underneath, and how much does the ice wall weigh

Okay, The Earth’s mass is about 5.972 × 10^24 kg.

And the sky weighs about 14.7 pounds.

This isn’t Quora or Yahoo Answers you know!

Then what could it be?

Are we thinking somthing like this

14.7 pounds ? Where did you get this info from ? Because that’s REALLY light for something as MASSIVE as the mass of the sky …
The mass of everything that composes the sky (which is just a LOT of gas molecules, ~80% of them being nitrogen) is at around 5.2 x 10^15 metric tonnes.

We’re 7.53 billion people on this lost rock in space, and the weight of an average human adult is 137 pounds, or 62 kg.

Therefore :
Amount of people * average weight = total mass
(7.53 x 10^9) x 62 = 466860000000 kg, or 1029250117236 pounds.

Of course this number is highly inaccurate but at least I didn’t just search the result.

What’s 101 kPa in pounds per square inch? I’ve misplaced my calculator, but that might explain things.

I suspect - or hope - it was misdirection

This means the sky weighs 14.7 lbs per square inch of earth surface which is roughly 11 billion billion pounds.

14.7 lbs per square inch of earth surface, not total weight of the sky !

(sorry for the french text lol)
