- 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.
There are fewer hydrogen atoms in a single molecule of water than there are fingers on my hand.
Check and mate.
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.
Ken M made a similar joke a while back right?
Obligatory “what about Jupiter”
Okay, I’ll bite. “what about it?”
It’s a Y-class brown dwarf star. Saturn likely is as well.
Today, the International Astronomical Union places the dividing line between brown dwarfs and planets at 13 Jupiter masses. This is the minimum mass required to ignite deuterium fusion.
And if you want more, check out what I said last time this meme was posted.
As someone who worked as an astrophysicist for 9 years, I assure you that the question of “what is a planet?” is a nuanced discussion with a lot of diverse opinions and no clear answer that gets endlessly debated by students as they learn that these definitions aren’t as cut and dry as irresponsible science communicators made it seem during the disastrous and highly politically motivated demotion of Pluto to dwarf planet.
IAU is well known for coming up with shitty arbitrary classifications about nomenclature that many astronomers don’t agree with. They are wrong here because they don’t take into account post-Cassini/Juno understanding of gas giant morphology. The IAU definition is outdated and highly misleading.
Copied from another reply I gave in this thread:
I’ve seen 13 MJ argued as a boundary, but it’s selected somewhat arbitrarily and based around idealized models of Deuterium fusion, which has never been observed, and which is a process these brown dwarves would only undergo for a brief flash in their early life. Deuterium isn’t abundant enough for its fusion to significantly alter the stellar morphology that has already become established for objects larger than Saturn. Saturn is our solarsystem’s example of an object that does not fit cleanly into one side or the other of a mass-based binary classification scheme for determining a hard boundary between “planet” and “star”. To understand what is a planet vs what is a star, study Saturn.
Ok, that’s interesting! I didn’t realize there was controversy around this definition.
The planet definition that excluded pluto was decided upon at the end of an IAU conference after most planetary scientists had left. As a result, only dynamicists are happy with it. Planetary geologists in particular HATE it and have always vocally pushed back.
I’d say Jupiter would need to be about 3 times massive to count as one. And more realistically around 10ish.
Iits not a lot, but it’s crazy that it happened twice.
My autopilot brain kept skipping over molecule and missing the joke lol.
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.
I skipped reading the word stars, and I thought it was deliberately wrong to rile people up.
This is especially true for blind people.
Woah!
That is a masterfully crafted mansplaining trap.
Chappeau.
Hat
That’s actually just the first part of the phrase. The whole thing is “je ne suis pas français, chappeau”
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 :Dje 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?
I didn’t get that behavior, but no significant result to explain the expression either.
But on the topic of weird behaviors, try to get copilot or meta AI to make a sign or an image for you with a phrase in a different language than your own.
They always translate it, I can’t get them to keep the exact text at all.
just the first part of the phrase
Seems to me like it was the last part of the phrase.
Actually it’s the middle
Ah okay, what’s the full phrase?
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.
Infinity beats both.
Yes, but both of those measures are in the finite space.
Ok I had to think about this for a second.
I have as many assholes as stars in our solar system, even though it seems like more to Lemmy.
