A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

I think an issue here is that taxonomic and colloquial definitions don't always agree.
Spiders are colloquially bugs, but they're not taxonomically "true bugs" (which is itself a colloquialism for Hemiptera). Tomatos are colloquially vegetables but taxonomically fruits...but afaik vegetable is a purely colloquial term anyway.
And as someone else in the thread mentioned, colloquial berries are not always taxonomic berries.
So...colloquially, "plants" sorta means, "macroscopic multicellular living non-animal thing," but taxonomically it's something else.
Similarly, “a planet” can be understood in technical or colloquial context which changes the meaning. It can have a specific meaning or a vague flexible meaning, just like with berries.
BTW raspberries are my favorite berries… sort of. Watermelons are pretty good too.
Actually planet doesn't have any hard set definition, we kind of just do it case by case because its damn near impossible to come up with a rigid definition that doesn't suddenly classify some planets as moons or some moons as planets or create weird situations in which an object can switch between the two.

And in that same article:
That's not even addressing the issue of rogue planets which were ejected from their star system. Many estimates say they outnumber the stars. Obviously when a planet is ejected it doesn't just disintegrate but by that poor definition it's no longer a ""planet"", so it's clearly a problematic definition.
