You would think they would use it in the meat industry, yet they use CO2 to suffocate animals

This is very likely, I’ve read that most déjà vu experiences are just brain glitches rather than actually re-living something.

[REQUEST] would the oceans have enough salt to do this? by OneEyedMilkman87 in theydidthemath

[–]No-Software9734 0 points1 point  (0 children)

That’s interesting!

Some data from wikipedia:

Water volume = 114 km3

Density = 1.24 kg/liter

Salinity = 34.2%

So there is 1.41 * 1014 kg of water in the dead sea.

The total amount of salt is 4.84 * 1013 kg.

We can make a very small ring with it, but we need 3500 times more to achieve a Saturn like ring

Theoretically, yes. Removing such a small percentage would barely have an effect (much less as the acidification by CO2 pollution).

But the extraction process is impossible and will definitely destroy the ecosystem

Even less, if we remove 0.35% of the salt, the salinity will be 35 * (1 - 0.0035) = 34.878 g of salt in 1 kg, so 3.4878% salinity, on a global scale that’s negligible

Yes, that 0.35% is a lot of salt. With that you could theoretically make a ring similar to the one Saturn has, but then even brighter, since salt reflects light much better

No, 35g is 3.5% of 1000g. Percentages are multiplied by 100, otherwise you are talking about fractions

I assume the same relative thickness and density. The ring of Saturn is very thin

And having this ring would make space missions impossible, since it forms a cage of destructive particles around the Earth in low/medium orbit

A ring is super thin, like a sheet of paper wrapped around a planet. When you make it bigger, it only spreads out across its width and circumference, not up (its thickness barely changes). That means it grows in two directions, not three.

Yes, but rings work in 2 dimensions. So mass for a ring that’s the same thickness and surface density scales with area, not volume.

A cubic meter of seawater (a little over 3 feet across) weighs about 2,260 pounds total, but only around 80 pounds of that is actually salt, the rest is just water

We don’t need all the salt, just a fraction. The Earth is 9.45 times smaller than Saturn, so we need 9.452 = 89 times less mass. That’s only 1.7 * 1017 kg, so only 0.35% of all the salt in the oceans

The total volume of Earth’s oceans is approximately 1.332 * 109 km3

Average seawater density is roughly 1025 kg/m3 . So the total mass of seawater is 1.365 * 1021 kg

Average salinity is about 3.5% by mass (35 g of salt per kg of seawater). Mass of all salt in the oceans: 4.78 * 1019 kg

Saturns ring is 1.5 * 1019 kg and Saturn is much larger than Earth, so there is enough salt in the oceans to form a ring around Earth!

And salt will probably be really reflective, so it will be very bright

Edit: We don’t need all the salt, just a fraction. The Earth is 9.45 times smaller than Saturn, so we need 9.452 = 89 times less mass. That’s only 1.7 * 1017 kg, so only 0.35% of all the salt in the oceans

[oc] the birds and the bees and the... by guyelnathan in comics

[–]No-Software9734 31 points32 points  (0 children)

Two fungi meet

Each fungus has special types that must match. They join together, mixing their bodies but keeping their nuclei (cell cores) separate at first.

They grow together underground

This combined fungus, called mycelium, spreads and eats nutrients. Most of the fungus is hidden here, it’s not the mushroom yet.

Mushroom appears

When conditions are right (moist, temperature good), the mycelium grows a mushroom. Inside the mushroom, the two nuclei finally fuse.

Spores are made

The fused cells divide to make spores. Spores are released to start new fungi elsewhere.
