To be fair, plants had ample sunlight to use for energy to break apart carbon dioxide. Undersea European life would need some other source of input energy.

- scheme271 3y agoChemosynthesis is something that's been observed where deep sea worms use hydrogen sulfide to convert co2 and o2 into sugars. It's possible that there are other chemical pathways that can be used where the o2 isn't used at all.

(Truth be told, Carp in general are so resistant to winter, I wonder if most carps have this trait in some amount)
- interestica 3y agoWait wait, Will European Life be the preferred term?
- agrippa 3y agoShould be “Europan” since “European” modifies “Europe” not “Europa”
- beAbU 3y agoWell, in some languages "Europa" is how it's called.
- shiroiushi 3y agoIf "Europa" is modified with an 'n' to form the demonym "Europan", is the star Vega properly modified the same way with an appended 'n' to form the demonym "Vegan"?
- kazinator 3y agoYes and it has appeared that way in sci fi.
- murkt 3y agoFor more confusion, let’s call some star “Vegetary”.
- amarant 3y agoOh! Now I want to try some Vegan meat! Not to be confused with vegan meat, much less Vegan vegan meat!
- pc86 3y agoI can't articulate why but I feel like "vegan Vegan meat" is more grammatically correct than "Vegan vegan meat."
- DiggyJohnson 3y agoYour intuitions are correct. We follow modifier ordering in English. Most aren’t aware of it. You can start here: https://learnenglish.britishcouncil.org/grammar/english-grammar-reference/adjective-order https://learnenglish.britishcouncil.org/grammar/english-gram...
- shiroiushi 3y agoIt's amazing: I only learned about that when I when I was middle-aged, reading some internet article. But as a native English speaker, I subconsciously already knew this rule, somehow, like it's hard-wired somehow. They never taught this to us in school.
- bee_rider 3y agoYou might be grammatically correct but it is much more confusing and funny to speculate about the possibility of European life.
- soco 3y agoEuropean life: "am I a joke to you?"
- samplatt 3y agoI mean... Barring some pretty big catastrophes occurring, Europa is likely to outlast Europe by several orders of magnitude. If the moon is happy to wait, they'll inherit the name regardless.
- robocat 3y agoBritannica: "During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds". Getting the Carbon from CO2 gets the backbone of organic compounds. Getting the Hydrogen from H2O is also necessary and is also part of photosynthesis. We have chemosynthetic bacteria on earth that use chemical energy rather than light. There is also a hypothetical biological process called radiosynthesis: https://en.m.wikipedia.org/wiki/Radiotrophic_fungus https://en.m.wikipedia.org/wiki/Radiotrophic_fungus I am not a biologist - but I find biology fascinating!
