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

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

I wonder if there exists people who aggressively believe mushrooms are plants, similar to people who defend Pluto as a planet. (slrpnk.net)

It was only in 1969 (nice) that fungi officially became its own separate kingdom.

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.

The International Astronomical Union (IAU) defined in August 2006 that, in the Solar System, a planet is a celestial body that:

  1. is in orbit around the Sun,
  2. has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and
  3. has "cleared the neighbourhood" around its orbit.

And in that same article:

It has been argued that the definition is problematic because it depends on the location of the body: if a Mars-sized body were discovered in the inner Oort cloud, it would not have enough mass to clear out a neighbourhood that size and meet criterion 3. The requirement for hydrostatic equilibrium (criterion 2) is also universally treated loosely as simply a requirement for roundedness; Mercury is not actually in hydrostatic equilibrium, but is explicitly included by the IAU definition as a planet

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.
