The barycenter is sometimes outside the diameter of the sun. Not always, and I believe not even usually.

Yes, today I'm being that guy. Still a cool factoid.

I'm kinda stunned that it's EVER outside the sun.

[-] Evil_Shrubbery 7 points 10 months ago

Yeah, that's the first thing I checked reading the og post before I was about to write 'there is no was it's outside the sun!' ... its such a tiny supergassy mass.

Outside the sun? Typical Visiblist. The Alfvén surface would like to have a word. https://en.m.wikipedia.org/wiki/Alfv%C3%A9n_surface

Well, while we are being 'that guy', factoid is one of those words which has changed its meaning by being used wrongly for so long that the original meaning has all but vanished.

A factoid is technically supposed to be something resembling fact, but not actual fact. (The Greek suffix '-oid' normally being used for that purpose, like in paranoid, "like knowledge" or asteroid, "like a star").

The best thing about factoid, is that factoid is now a factoid. Because it resembles what it is not lol...

Anyway, nowadays, you are allowed to use it the way you did, at least in the descriptivist world view. The prescriptivists may disagree, however. And those people are often 'that guy' ;)

[-] davidgro@lemmy.world 4 points 10 months ago

I'd say that the original statement not including "sometimes" does in fact make it the 'not a fact' type of factoid!

[-] setInner234@lemmy.ml 3 points 10 months ago

Good point!

[-] GraniteM@lemmy.world 4 points 10 months ago

Well, now I want to know if there's a regular schedule to the Jupiter-Sun barycenter being in or outside of the Sun, and how we can schedule holidays around it.

  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

If you are here asking: "Is this a science meme?"

Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.

Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.

We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.

See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.
