  Seems to be easier focusing with the calcite as well as durability in the scratchy sand environment.

  Additionally, more derived/later species had aspherical lenses to compensate for the spherical aberration and dual layer organic→calcite lenses to allow for more of a refractive gradient to counteract the double imaging of calcite alone.

  Modern arthropods probably done use it on land because of an inability to accumulate it in an efficient manner. Water arthropods like crustaceans probably done because it’s metabolically expensive to do these things when chitin alone can make for useful eyes.

  Evolution is more of a “good enough” kinda situation.

  From my searching, it would seem that trilobites used calcite to reinforce their hard parts as well. Crustaceans have amorphous calcium carbonate reinforced exoskeletons through mineralization, but no calcite land arthropods do not seem to have this mineralization tho.

  I’m no expert. Just like using Google Scholar to answer questions I find interesting.

  Jesus fucking Christ. Just pay attention to your goddamn children and talk to them. Listen to them. They are no one else’s but your own. And if you didn’t want to care for them, you shouldn’t have had them. And if it was a mistake, abort or adopt them out.

  They are neither slaves nor toys. They are just little humans that want to learn and grow up to be big humans. Teach them.

• ⁨Comment⁩ on ⁨Oxygen⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Simple. It’s the combustion process of the luminiferous aether, which is like the cosmic equivalent of air, just finer and undetectable by modern instruments. See, the sun doesn’t need oxygen like regular fires because it’s tapping into this vast reservoir of aether that permeates the entire universe. As the sun rotates, it creates pressure waves that compress the aether particles, causing them to vibrate intensely. These vibrations generate heat through a process called “aetheric oscillation.”

  Now, since the sun is massive, it can harness an unlimited amount of aether, and the energy release is what we experience as sunlight. Think of it like a giant cosmic steam engine, except instead of coal and water, it’s running on pure space aether and high-velocity vibrations. And that’s why it keeps burning without needing any of that “earthbound” oxygen nonsense. It’s all about the oscillation efficiency, really.

  They are hard light projections. Their physical bodies are their gemstones. They are genderless, female presenting, sentient space rocks who reproduce via the various bodily secretions of their supreme diamond leaders.

  Where White Diamond comes from is a true mystery, but I like to think of her like the Monolith. The creation of a long gone organic species that wanted to seed the universe with life. Only white was a bit more zealous for inorganic life forms and than simple organic life.

  As for Steven, it can be assumed, since the gems can shape shift their hard light projection forms, that Rose shape shifted a functioning human female reproductive system centered around her actual gemstone.

  But it’s whatevs. I’m a big Steven Universe fan. Free therapy. Never had a cartoon make me cry more than that show.
