Water

Me: That doesn't seem right. OH. Oh, I am stupid.
- *OH₂
  
  I am impressed by how clever that was. Well done.
- Not stupid. Our brain can just get tripped up sometimes and read what it expects to read instead of what's really there. The sad part is that there are educated people in the US even today that would be surprised or even argue against you if you stated the other version (more atoms in a glass than in our galaxy). Our science education is woefully lacking now.
  What blew me away that I learned not too long ago is the notion that if the galaxy was the size of the US, our solar system would be the size of a fingerprint. Try to even visualize that. (reference is the Epic Spaceman YT channel)
  
  We had a young, hippy science teacher through 70s grade school. Looking back, that woman made more impact on my life than any other teacher.
  Every year, every fucking year, she'd start with the difference in fact and opinion. "Yeah, I get it already. Can we move on?" Apparently not many others got that bit of education.
  She taught the scientific method and how it works, she taught how to experiment, how to measure. I still set a beaker down and wait for it to settle before moving on. And I'm not in science!
  
  NGL our solar system being the size of a finger print is (somehow) bigger than I expected.
  Another fun size thing I heard recently was that if an atom were the size of a football stadium then the nucleus would be the size of a pea.
  
  A fingerprint? That's actually bigger than I figured.
- I very slowly zoomed in on the actual words in the post.
  Started off processing "molecule" as "mole", "solar system" as "galaxy", and thinking "ha, don't know if that's true but it sounds both plausible and neat".
  
  There are definitely more hydrogen atoms in a mole of water than stars in the Milky Way.
  The Milky Way has somewhere between 100 and 400 billion stars according to Wikipedia (1*10^11 to 4*10^11). A mole of water has 6.022*10^23 molecules in it, each of which has two hydrogen atoms in it for a total of 1.2044*10^24 hydrogen atoms.
  10^24 / 10^11 = 10^13 which is ten trillion. So, a mole of water has roughly ten trillion times as many hydrogen atoms as the Milky Way has stars.
  
  Wasn't thinking moles, not that technical, but it sounded plausible vs. the number of stars in the Milky Way.
  Wait...
- The glass of water is a bit misleading. Your brain starts thinking about all the water molecules inside. That's all.

That is a masterfully crafted mansplaining trap.
Chappeau.
- That's actually just the first part of the phrase. The whole thing is "je ne suis pas français, chappeau"
  edit: Ok this was supposed to be a joke about mansplaining something you know nothing about, but we fell into Poe's law.
  
  je ne suis pas français, chappeau
  I tried googling this to see if I was missing some reference or something and it led to strange google behavior I've never seen before... When I search "je ne suis pas français, chappeau" without the quotation marks, Google automatically changes the French to English in the search bar when I hit the search button.
  Anyone else experienced this? For what possible fucking purpose would that exist?
  
  just the first part of the phrase
  Seems to me like it was the last part of the phrase.
  
  Huh, this is an interesting intercultural communiaction trap.
  In my area, this is just used as a shorthand/slang/idiom for "nice, i respect that" or in place of a nod or "thank you"
  Edit: i should add, that as far as i know, a chappeau is a type of cap or hat? Right? have to google that.
  edit2: yes, a hat. The origin of the use I know for it is probably a salute where you touch your finger or hand to the hat, or lifting the hat.
  Here saying "hat" seems to be enough :D
- Hat

It's 2 > 1, so correct two hydrogens versus one star: Sol
- O sole mio!
- What about celebrities?
  
  Celebrities contain more than two hydrogens, true.

There are more memes estimating the size of the universe than there are stars in the galaxy.
- Solar system.
- You’ll have to prove this one.

With greater hydrogen comes greater responsibility.
- Like twice as much

Most people have more balls than there are stars in our solar system.
- Wait, are you counting ovaries?
  
  The average human has somewhere between 1.1 and 1.4 testicles.
  Late edit: I was not sober when I wrote this and I definitely did the math wrong.
- Not Hitler though.
- I have a dog, so I'm bringing up the average. We've got (dog-sare) tennis balls galore!

Number of hydrogen atoms in a single molecule of water (H2O): 2
Number of stars in our (ENTIRE) solar system: 1
That's the joke.
- Thanks, I never would have been able to understand 2>1 if you hadn't written up that amazing power point slide.

Petition to classify Pluto as a star
- We can just add it to Jupiter.
- petition granted
- Even with the +200 other dwarf planets we wouldn't get there.
  
  Where is there? 2?

I skipped reading the word stars, and I thought it was deliberately wrong to rile people up.

My autopilot brain kept skipping over molecule and missing the joke lol.

There are fewer hydrogen atoms in a single molecule of water than there are fingers on my hand.
Check and mate.

There actually are more molocules of H2O in 10 drops of water than there are stars in the observable universe.
- Optimists: the glass is half full
  Pessimists: this half empty glass of water has more molecules than there are stars in the observable universe; life is meaningless
- I don't think we can see much, now can we?
  
  "Observable universe" isn't how much we can see, rather how much it is theoretically possible to observe by any physical means.
  I also don't think that water drop fact is correct. The estimated number of stars in the observable universe is 10^24, which is about an order of magnitude more than 1 mol, and 1 mol of water is about 18g, which is quite a bit more than 10 drops.

Also interesting: If you were to take your nerves out and lay them end on end you would die.
- How do you define "closer" here? I'm about 1.8m removed from the size of an atom but well over 299 thousand kilometers from a light second.
  
  orders of magnitude soz
  physics causes brainrot and everything becomes OOM
  
  You're comparing them linearly, a comparison for which the statement is false.
  The statement is true multiplicatively/logarithmically/unitarily.
  Atomic radius is ~ 1e-10m
  Light second is ~3e8m
  Your height can be measured as 1.8e10 atomic radii.
  A light second can be measured using only 1.7e8 humans who are 1.8m tall.
  Does that help?

Ken M made a similar joke a while back right?

"You are technically correct, the best kind of correct."

This is especially true for blind people.

Woah!

I have as many assholes as stars in our solar system, even though it seems like more to Lemmy.

I couldn’t find the clip, but first thing that came to mind was the StarTalk Live with Buzz Aldrin and John Hodgman.
Hodgman: “maybe they’ll find H 2 2 2 2 O!”
Edit: crap, I have to call myself out. I failed to read completely, thought the screenshotted poster accidentally changed one part of the comparison, instead of deliberately changing both parts. If the original was molecules in a cubic inch of water vs stars in the observable universe, I read this post as atoms in a molecule vs stars in the observable universe.
Apologies, I discovered I was a fool and was excited to share my discovery.
- No need to feel foolish. You have introduced me to yet another John Hodgman project. And that's all that matters in this world.

Ok I had to think about this for a second.

There might even be more hydrogen atoms in one molecule of water, than there are universes we live in!

Reminds me of the time someone on Xitter said that there are more trees on Earth than there are stars in our Galaxy. They got ratio’d pretty damn hard for it. -_-
- Going by the top Duck duck go results for "how many stars in our galaxy" and "how many trees in the world":
  "According to Jos de Bruijne, a scientist at the European Space Agency (ESA), the current estimate is between 100 to 400 billion stars."
  and
  "There are an estimated 3.04 trillion trees in the world."
  
  Yeah, if you think of it, stars are relatively rare in a galaxy when compared to living beings which are born to procreate. But once you go out to universe, it becomes true.
  
  That’s why it’s so crazy that that person was shat on so hard.
  Not finding the actual Tweet yet (hard to navigate without an account), but here’s a video covering it:

  Also sorry for the billion edits. My brain is giving up on me tonight.

Obligatory "what about Jupiter"
- Okay, I'll bite. "what about it?"
  
  It's a Y-class brown dwarf star. Saturn likely is as well.

So do we not count the mini suns being created at places like Livermore Labs? 🤔
- We can't make plasma dense enough to have significant convention over radiance, and the longest active run is only a minute or so. We're a good way away from plasma stable enough to be called a star, although it's getting closer. Hydrogen bombs are probably the closest we have so far.

Infeel like this gets reposted here at least once a month, but this one has a different t pic, and way more likes

clearly never been down the hollywood walk of fame

Uhhhh... No. Pretty sure it's about equal.
- ±1
  
  Weird water molecule if it had only 1 hydrogen atom. Pretty sure we call that ~~peroxide~~ hydroxide (tired haven't slept in days).
  Though adding 1 hydrogen for H3O1 would probably win you some nobel prizes
- What's the second star in our solar system?
  
  Ringo
  
  No one asked but you, so thank you.
  Also,
  Ringo.
- What's the other star in our solar system?
