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)
- 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.
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.
- just the first part of the phrase
  Seems to me like it was the last part of the phrase.
- 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?
- 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

What about celebrities?
- Celebrities contain more than two hydrogens, true.
O sole mio!

There are more memes estimating the size of the universe than there are stars in the galaxy.

You’ll have to prove this one.

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

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.

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!

Petition to classify Pluto as a star

We can just add it to Jupiter.
Even with the +200 other dwarf planets we wouldn't get there.
- Sedna had it's chance.
- Where is there? 2?

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

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

Check and mate.

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

Ken M made a similar joke a while back right?

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?

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

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

This is especially true for blind people.

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.

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!

Obligatory "what about Jupiter"

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

Woah!

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?

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.

clearly never been down the hollywood walk of fame
