Our planet actually gets roughly 50,000 tonnes lighter every year. (We gain 40,000t from meteors but also lose about 90,000t of hydrogen.) https://www.cbc.ca/radio/quirks/sept-1-2018-gene-editing-in-dogs-wildfire-prediction-zika-fizzles-and-more-1.4804892/is-earth-getting-heavier-or-lighter-1.4804900
Math does not check out.
40 - 90 = -50. Not 50,000.
Edit: from the source, the correct statement is “We gain 40 000 t from meteors but also lose about 90 000 t of hydrogen.“
What is heavier, one ton of meteors or one ton of hydrogen?
African or European?
Depends on gravity ;-)
Only if you use imperial units. The article uses tonnes, which is a unit of mass, not weight.
Yes but I would interpret “heavy” to be a function of weight, not mass.
Steel is heavier than feathers
Well meteors are heavier than hydrogen
Whoops my bad, my brain was in a different place while I typed.
Don’t forget to account for all the helium leaking out of balloons. That’s part of the reason the earth gets lighter too.
And every time they manufacture a Bic, the world gets a little lighter.
There’s two men in a boat, and they have three cigarettes but no matches. How do they manage to smoke?
Two men in a boat is already pretty hot for some people.
Yeah, and when you burn that fuel it gets hotter, and that makes it a little lighter too.
There are more Olsen twins on Earth than there are stars in the solar system
Isn’t God just amazing?
Conservation of mass is niche
To follow that logic, this must also be niche: when you eat a hamburger, you gain weight exactly proportional to the hamburger.
Supernova explosions are so damn bright that they can outshine the rest of their host galaxy, but in reality, most of their energy is not even released as light. It’s carried away by an ungodly amount of neutrinos
Earth actually gets lighter ever so slightly from solar winds blowing shit off the planet, and gains less back from meteor strikes than it loses.
The filling of large hydro-electric dams slows the rotation of the Earth by a measurable amount.
First pass googling this returns very low information quality. I suspect “calculable” is more more like it than “measurable” but would love to see a source where measurements had been made that showed this effect greater than standard error.
This begs the question: how “heavy” IS the earth?
We know it’s massive, but weight is not mass, and weight is a function of mass accelerating through space-time because of gravity… Which… Is… relative?
So could I say that the entire earth weighs… the same as… me? Since I am the body by which the earth’s space-time relatively warps around? Or… Because I’m accelerating away from the ground at my feet, but then also thus the earth from me because of newton’s third law?
Checkmate, atheists.
Tldr: The earth weighs the same as you do, because of special relativity and newton’s third law.
Yo momma so fat, she weighs the same as the earth!
Wait… Weight is a until of gravitational force right? And that force weakens as objects move away from each other. So wouldn’t the planets weight become less if you made tall buildings?
Feels like the answer must be technically yes, but practically no. Would make a great xkcd “what if.”
skatole occurs naturally in the feces of mammals and birds and is the primary contributor to fecal odor.
In some ice creams, it’s added as a flavour enhancer.Then I also process parts of meteorites and exoplanet-like materials are used that enrich the planet with mass.
When water turns to ice it increases about 9% in volume but ice weighs about 9% less than the water.
Wouldn’t the mass remain the same, it’s the density that drops and that is why it floats
Imagine believing that relatively subtle changes in temperature change the mass of a quantity of mass.

However, ice is less dense than liquid water, a property that is unique to water. Having a lower density means that ice floats when placed in liquid water. When water freezes, it occupies more space than in its liquid form because its molecules expand. Therefore, if we have 1 liter of ice and 1 liter of water, the water will weigh more because it is denser.

Isn’t that just an explanation of density? When you freeze some water it will still have the same mass, just a slightly higher volume. As the density is lower.
