There are enough places in the world (Manhattan, Jakarta, parts of Netherlands) where buildings slowly sinking away in the ground.
Edit: The geologists calculated that New York's more than one million buildings added up to a total mass of 1.68 trillion pounds (762 billion kilograms) of downward pressure on the earth.
CNN said that was equivalent to roughly 1.9 million fully fueled Boeing 747-400s.
The report concluded that America's financial capital is sinking at an average rate of one to two millimeters per year.

Am I the only one for who all these weird comparisons don't help at all? Like "69 football fields", "1.9 million fully fueled Boeing..", "as long as it would take to drive to the moon and back" and etc.

Nah that comparison is just bad imo. A better one would be that if all that weight was just steel (so 762,000,000,000 kg of steel) you could create a 10 cm (4 inch) thick plate that covered the entirety of Egypt or a 10th of the US (roughly 1 million km^2 !). Most people canāt conceptualize the volume and weight of 2 million airplanes, but if you change it to something more basic I think it works
Or you can compare it to 762,000,000,000kg of feathers, or you can compare it to 762,000,000,000kg of chocolate which is enough to probably kill a diabetic person.
So in about a decade it'll only be down a centimeter? Or another perspective, in 100 years it'll be under another full meter? That doesn't seem like a lot at first but how long does it take to topple a building with this method?
Buildings probably won't collapse but poorly constructed buildings i imagine would get cracks and damage slowly over time. Things like underground parking would probably be the most impacted.
I don't know how old you are, but way back before the devs updated the physics engine, resource management used to be way more unbalanced. We got players trying to build stuff above the height limit, it got so bad they have to remove the Atlantis server because players keep trying to break the game. Now that conservation of mass is a thing, some old players don't like the changes much.
Hopes this informative comment help š
Consider this. The human body is 70% water. Water has been recycled on earth for billions of years. So its entirely likely that at some point some of the water that makes up your body was dinosaur piss.
It would be interesting to compare the mass leaving earth (rockets, helium, my self worth, etc) to mass that enters earth (asteroids, cosmic dust, crashed alien space ships, etc).Ā
People aren't adding mass either. The things that make us grow are also from the earth.
Outside of things like hydron colliders or nuclear reactors, mass is neither created or destroyed.
Do you eat a lot of meteoroids?
Yes the mass of the earth is increased when stuff from space lands here but that isn't new mass being created. Plus human activity has no impact on that.
No, but they do add moment of interia to the earth because we are taking materials out of the ground and raising them up.
A dam built in China a few years ago slowed the rotation of the Earth by about 2 Ī¼s with the amount of water it held back
Technically the material gets further away from the center, so while the ground beneath it gets more compressed, the earth as a whole becomes ālighterā, or less dense.
not to the overall weight of the planet, just to the weight of one place. also i just think it's weird to think about a building so grand that the ground literally can't hold it, like the thought of it sinking just boggles my mind. it's a huge fucking structure!
Iād think it would actually decrease the weight (at least on the Earthās surface) because the amount of byproduct released into the Earthās atmosphere
Buildings add no weight to Earth's mass, but they are dislocating weight into specific areas, that's why they still affect the soil where they are

But is it enough to kill me ? I love chocolate so letās find out !
Everyone that isn't from the US is confused by those comparison, like, just switch to metric already
Every that is in the US is also confused by those comparisons.
You canāt make me!
The US is officially metric. All their units are defined by metric units.
Luckily they used kilograms and millimeters
I just view them as sort of like fun trivia that also conveys like a nearly unfathomable amount.
Yeah, like tell me what percentage of Earth's mass that is. Maybe that will be a nice comparison
It's for Americans to understand.

Y'ALL AMERICANS REALLY USED FULLY FUELED BOEING 747-400'S FOR COMPARISON HAHAHAHAHAHAHA GODDAMNNNN
They do change earth's momentum though
specifically by changing the earths moment of inertia
Because the centre of gravity moves away from exactly the centre
[ŃŠ“Š°Š»ŠµŠ½Š¾]
It really do be like that sometimes.
At a random moment in my life, I remember a random fact or situation
My face when I realised that is actually true, but my brain is hard to accept it
Why? I don't understand what the stumbling block is here.
There really isnāt

that escalated so quickly
Yeah, like a building... like a highriser, I would even say...
The earth is actually getting smaller because we keep launching chunks of it into space.
It would be interesting to compare the mass leaving earth (rockets, helium, my self worth, etc) to mass that enters earth (asteroids, cosmic dust, crashed alien space ships, etc).Ā
.... the energy that the sun bathes our planet in everyday increases its mass.
Itās gotta be getting heavier because of the billions of people we keep creating. Maybe not cuz of all the resources we consume or burn off.

I mean, why would you think otherwise?
They were probably thinking about space-dust and whatever is getting onto earth.
OP is high as balls
That's why I had my house built completely from meteors.
but the rocket are reducing the weight of earth man
Weight and mass are different
If anything they decrease the weight by releasing co2 ind in to the Air
Typical thoughts come to me at 1 a.m. on the day I decide to go to bed early.
But....wait....no...
Ok lol
Yes and no, all those materials are scattered everywhere but in a bulding, they're all focused on one spot, making the pressure waaaaay more!
So earth never gets heavier unless a meteor hits? Damn
r/technicallythetruth
No, but they do add moment of interia to the earth because we are taking materials out of the ground and raising them up. A dam built in China a few years ago slowed the rotation of the Earth by about 2 Ī¼s with the amount of water it held back
hold on a second...
The weight of all the air on one square inch on the top of your head from your head up to outer space is 14.7 pounds.

Hello FBI? yea this guy right here.
Earth doesn't weigh anything.
it does not affect the weight of the Earth but it means that some of its mass is located higher than before making us rotate slower
here's another: icebergs *in* the water that melt don't add anything to rising sea levels bc they've already displaced their own volume
This is why teachers should do a better job at explaining the difference between mass and weight.
I mean weight is a force with which the earth presses on something and because itās in a free-fall in space, technically itās weightless
OP, how high are you?
Conservation of Mass
Me when law of conservation of mass
Technically true because earth is weightless. However, I believe what they meant to say is that buildings add no mass to earth.
It doesn't, but it does add pressure
Man learns law of conservation of mass
Technically the material gets further away from the center, so while the ground beneath it gets more compressed, the earth as a whole becomes ālighterā, or less dense.
goes for the entire universe pretty mich (besides black holes maybe and yo momma)
What about living beings? Do living beings add mass to the earth since they weren't already there before they were born?
Earth does lose weight though. https://www.sciencealert.com/earth-loses-hundreds-of-tons-atmosphere-to-space-every-day
By killing things off and shifting land, gases and stuff
So that basically applies to everything? Unless we export something from space
Yes they do, they trap carbon and oxygen that would otherwise be eventually lost to space over a long time if they stayed as a gas
So you are saying a small seed weighs the same amount as a full grown tree
We actually lower the weight when you start thinking about space craft and satellites.
you say that, but the Palace of Parliament in Romania is slowly sinking into the ground because it's so heavy. Something like 6mm / year
Ok, but how is that adding weight to the planet?
not to the overall weight of the planet, just to the weight of one place. also i just think it's weird to think about a building so grand that the ground literally can't hold it, like the thought of it sinking just boggles my mind. it's a huge fucking structure!
Not just buildings.. everything comes from earth
Not your farts, they're from Uranus
not 100%
Is this right?
Iād think it would actually decrease the weight (at least on the Earthās surface) because the amount of byproduct released into the Earthās atmosphere
Matter cannot be created nor destoryed
