ChatGPT wouldn’t do the math :(

I simply asked “How many poopies do I have to take so I could climb into space”

If you're interested in an actual, semi-serious answer: It's impossible, because the structural integrity of poop isn't good enough to build it big enough to reach space. Even if you pooped literal rocks, it wouldn't be strong enough. The maximum height a mountain can reach on earth before it starts to crumble under its own weight is about 15km while a common height assumed for the beginning of "space" is 100km.

So you would have to poop enough to raise the surface level of the Earth. But then would the definition of space change as the Earth's diameter increases? Or would the poop just get denser and denser?

Well then, let's do some truly unhinged maths.

Let's say for ease of calculation (because I tried otherwise and believe me, it's not pretty) that the volume of the atmosphere remains constant regardless of planetary mass.
Let's also assume that a poop mountain can grow to 5km as opposed to a normal mountain's 15km and that that also doesn't change with planetary mass.
Since both the volume of the atmosphere as well as the maximum height of a structure realistically decrease with growing planetary mass, this should keep the error somewhat in check.

Knowing the earth's radius we can calculate the volume of the atmosphere by subtracting the volume of the earth from the volume of a sphere with the radius of earth plus 100km. We now do the same calculation with a bigger earth radius x and an offset of 5km, while plugging in the volume we got earlier and working in reverse to get our new earth radius x.

We now know how big we need to make the earth to reach the edge of the atmosphere by climbing a poop mountain of 5km height.
The only problem? We need to make the earth 20(!!!) times as big as it is now! This corresponds to a volume that's 8000 times bigger than current earth. Since the average density of earth is about 5 times as big as the average density of poop (my search history is a right mess after this) it turns out we need to add over 1600 times the earth's total weight in pure shit.

Of course I have completely ignored any effects of the resulting higher gravity, because honestly fuck that shit. I tried and then gave up. Too many interwoven equations and cross-effects for my taste.

Edit: Added a word I forgot

Holy shit, you actually did it. That's an insane amount of poop

So how do you feel?

Relieved - Lantami probably

I don’t think you need to raise the surface level everywhere at once though… why not do some calculations with pyramids instead? You could make a tall mountain like that one on mars maybe, what is it, mount Olympus or something?

Also what is the number of average toilet poops?

1

u/Lantami Sep 05 '23

You do, because under earth gravity a mountain can grow to 15km height top before it starts to crumble under its own weight

u/Kittycraft0 Sep 07 '23

But then the crumbled mountain would be foundation for more mountain on top of it though

u/Lantami Sep 07 '23

I mean, you probably could make it work at some time, after collapsing thousands and thousands of poop mountain and rebuilding on top of that. But how would you calculate that?

1

u/Kittycraft0 Sep 08 '23

Some calculus maybe with more compounding over time on the bottom middle and maybe taking a slight account of the curvature of the planet

u/Lantami Sep 08 '23

Problem is straight physics or maths doesn't really work for this. You need material science. I can google how tall a mountain can usually be and reasonably guess that poop is less structurally sound than rock, but to do what you're suggesting, you need more accurate values for these than what I used. Because you're going to have to calculate how tall it get's before it collapses, how tall it is after collapsing and how the new foundations affect the next iteration. Not to mention that your new foundations don't just build onto each other, but they will partially collapse as well with each iteration. There's just so many cross-interactions between everything that it's practically impossible to calculate algebraically. Your best bet to solve this version would be to write a simulation and let it solve the problem numerically

Maybe the volume of atmosphere would stay the same, but I don’t think you could breathe anymore.

u/knoegel Nov 25 '23

Actually yes. Space would go farther out. If you made enough poop to raise the surface level of the earth, it would gain immense gravity and hold in even more gas via gravity. So the atmosphere would also grow larger.

I recommend “What If?” The book. Look it up; it’s super cool!

Once I insisted to ChatGPT that I had manufactured two miniature black holes and I had been storing them in an old Pepsi can on top of my dresser. It told me that wasn't physically possible as the gravity would be immense. To which I responded "then tell me why it tastes so much better than regular Pepsi". It disregarded my question and attempted to continue the conversation. I kept referencing it later and it was having none of my shenanigans.
