Male ducks have a corkscrew penis almost as long as their body. Female ducks have vaginas that corkscrew in the opposite direction, with false endings. Ducks do not have consent, so nature found a way.

There a more hydrogen atoms in a single molecule of water, than there are stars in the entire solar system.
The universe is jerking it
Time derivatives!
- Rate of change in position is called velocity
- Rate of change in velocity is called acceleration
- Rate of change in acceleration is called jerk
- Rate of change in jerk is called snap
- Rate of change in snap is called crackle
- Rate of change in crackle is called pop
Snap crackle pop and Bob’s your uncle, easy peasy
This explains the sounds when I move to get up, these days.
Is it snap? You might have to slow down your rate of jerk
And if I recall correctly
- Rate of change in pop is called lock
- Rate of change in lock is called drop
When the fuck could those possibly be useful? 😆🙃
IIRC the James Webb had/has max snap, crackle and pop tolerances. Not sure about these two.
Not sure about anything past crackle, but minimum snap trajectory is widely used in efficient path planning for quadcopters.
In aerodynamics I guess
I can’t even comprehend what something beyond jerk means in reality or how to even produce it by physical means
Well these are higher order derivatives, so they do have physical meaning but the latter ones are increasingly abstract and subtle from our normal earthly perspective.
If you think of a stable and perfectly circular orbit, that’s a steady and constant acceleration. Then if you thrust to make it elliptical, you’re changing the acceleration which can be measured as jerk. But then if that thrust itself is variable, you can measure its changes as snap. And then of course the rate of how much you change that is crackle, and so on.
They aren’t useful. It is just scientists memeing. Any research that involves anything past jerk would be esoteric.
Wait, what. 🤩
Don’t forget jitter, now!
Which one is jitter?
None of those, but I think a series of irregular jerks could be considered jitter.
So trump, elon and hegseth form a jitter?
I only know jitter as irregularity in data flow (e.g. network packets).
Jerk is sometimes called jolt though. Both terms seem fitting to me. Supposedly in roller coaster design, having too much jerk/jolt can be quite unpleasant for riders. Which kind of makes sense, if the acceleration varies too wildly I could see that making me sick.
Snakes have two dicks.
I mean… Everyone who’s scrolled on e621 for 2 mins knows this
They’re Klingons?
“Hemipenis”
See also: Brodozer and Pavement Princess.
Like a… bifurcated one similar to their tongue or they have two in different parts of their body? And do females also have two holes? Are snake threesomes a thing?
So many questions!
If you took all the DNA from every cell of one person and laid it in a straight line they would die
Relevant xkcd: How long would you survive with no DNA?
Red grapefruits were originally created by planting yellow grapefruit near a radioactive source with the express purpose of creating mutations in the plant.
From what I read, red grapefruit like Ruby Red existed naturally, but the atomic mutations only made them more red / not fade over time.
Commies! They’re in your fruits!
Commies and fruits have been bedfellows for a long time.
So that’s where Oxygen Not Included got the idea from.
Toads swallow food with their eyes. When they snag some food into their mouth they close their eyelids, and their eyes go inside and help push food down the throat before coming back up to the front of the head.
Sounds like a usefull skill for the next all you can eat buffet.
There are more hydrogen atoms in a single molecule of water than there are stars in the solar system.
:P
For now…
you mean the galaxy, a solar system usually has 1 star.
Woosh!
And a water molecule has 2 hydrogen atoms…
Yeah and how many hydrogen atoms are there in a SINGLE water molecule?
If memory serves, binary star systems are more common but the statement was specifically on the system around Sol
Some have more than one, and no solar system has zero stars, so the average is greater than one.
What about when the stars degrade into a dwarf?
Clouds.
- polar stratospheric clouds play an important role in creating the ozone hole
- the highest clouds on earth are about 80 km high
- in the mid-latitudes most rain is cold rain, that means it leaves the clouds as ice and melts on the way down
- pure water droplets without an aerosol inside (cloud condensation nucleus) freeze at about -40°C, sea salt aerosols make cloud droplets freeze at about -38°C, …
And there’s much more to be found.
All the planets in the solar system can fit between the earth and the moon
And murcury is the closest planet to all of them!
Australia is wider than the moon. If earth had the size of a football (soccer), the moon would be about 7m away. If the sun had a diameter of 1m, Neptune would be 5.6km away. In that scale model, the next star would be placed in the outer planets. Space is insanely big.
I’m confused what you mean by wider. As far as I can tell Australia is about 4000km wide and the moon’s circumference is about 11000km
EDIT: it’s late and I am dumb, I take it you mean the moon’s diameter! 3474km
7 meters?
I looked up the circumference of a football and it said about 70cm. As the moon is about 10 times the circumference of the earth away, that’d put the moon at 7m away.
Diameter or circumference?
A 70cm diameter soccer ball (>2 ft across) would be kinda fun. Except headers the CTE would be even worse!
All Very true facts. I admit I was and am still taken aback by the measurement and extrapolation of linear distances using… circumference.
Yeah it’s a weird way to make the distances sound shorter than pi*(a measurement we all can visualize).
Gonna need a fact check on this one.
Are we counting the gas of Jupiter or just the solid core? Same for the others
Actually, Jupiter doesn’t have a solid core the way you think! The gases just get so dense at the core that it starts to behave like a solid. You couldn’t, like, blow away all the clouds and have some rock to wander around on.
Whole planets. You do have to cant Saturn because the rings don’t fit
they’re ephemeral anyway
That’s insane when you really think about it.
I doubt we’ll ever leave our systemIf you count Voyager, we already have.
Otherwise … Yea, I’ll be surprised if society in general even makes it to 2100 unscathed.
Bad news with the AMOC modeling yesterday. 2100 is starting to seem optimistic…
Voyager is fantastic, but it’s still way, way closer to the solar system than anything else.
An excerpt from Wikipedia:
At this rate, it would need about 17,565 years to travel a single light-year.[78] To compare, Proxima Centauri, the closest star to the Sun, is about 4.2 light-years (2.65×105 AU) distant. If the spacecraft was traveling in the direction of that star, it would take 73,775 years to reach it. Voyager 1 is heading in the direction of the constellation Ophiuchus.
This is why I don’t get excited to hear about the discovery of ‘Earth-like planets’ 182 light years away.
30 years ago we didn’t even know for sure if planets around other stars was a common thing and had no expectation we’d actually know their chemical compositions
Yes, and they are still on a galactic orbit, not a solar orbit. They are, unquestionably, the first things we’re sending off, regardless of whether they arrive anywhere substantial.
Sharks are older than trees
Sharks are older than fire.
Sharks existed before there was enough O2 in the atmosphere to sustain a fire.
They must have been really hungry for a long time before their staple diet of attractive people on beaches arrived :D
What. The. Fuck.
The real facts are in the sub-comments
Also trees existed before bacteria did. So when a tree died it just fell over and sat there for a while. Never decomposing
I don’t think trees are older than bacteria in general. Bacteria still existed, it’s just that bacteria didn’t develop the ability to break down wood until long after trees had come on the scene
It’d be remarkably fortuitous if bacteria evolved to break down wood before wood existed.
The earliest trees evolved around 400 million years ago.
The ancestors of bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago.[23] For about 3 billion years, most organisms were microscopic, and bacteria and archaea were the dominant forms of life.
Yeah, I was quick in writing that comment
that isnt true, there was no decomposing fungi, bacteria that evolved yet at the time of the carbiniferous peroid, and those “tree” were actually gigantic gametophytes(posessing half the chromosomes) of early bryophytes. the actual first tree dint evolve til after that peroid.
Wild fires must have been insane.
There’s more ships in the ocean by weight than there’s fish.
[edit]
See my other comment below, probably more accurate to say the total weight of all ships is around the same as the total weight of all ocean fish.
There are more aeroplanes in the ocean than ships in the sky.
And there’s far more biomass of farm animals than what we’d usually think of as “wildlife”.
Human chemical plants now do most of the nitrogen fixation in the nitrogen cycle, too.
Biologist: “define what you mean by ‘fish’.”
ducksandruns sorrynotsorry

By how much?
(And how do we know this?)
From an old XKCD What-If, which put it at 2.15 gigatons ships vs 2 gigatons fish. But that uses quite old numbers.
Looking at up to date data from the UN there’s 2.4 gigatons of ships. Note that this is dead-weight tonnage, so fully loaded. Empty is probably more like ~0.5 gigatons, so it’d depend on how fully loaded the ships are.
And a quick search turns up this paper which references several estimates for fish biomass form other papers, which would put fish biomass somewhere between 0.4 and 4.9 gigatons depending on estimate.
So I put it too strongly saying “more”, it’d be more accurate to say fish biomass and ship mass is within the same order of magnitude. Also note that it’s only fish, not like plankton, shrimp, etc.
In or on?
The moon is currently drifting away from the Earth. Eventually, that will make total eclipses impossible, so enjoy them while they last.
Fast forward a few billion years, and the Sun begins to swell up, engulfing the closest planets. At some point, the atmosphere of the Sun could begin to cause drag on the Moon, slowing it down. If so, the Moon begins to crash down on Earth. Once it reaches the Roche limit, it gets shredded into kwazillion bits, and the Earth will have rings, just like Saturn.
Something like a fifteenth of all humans who have ever lived are alive today.
Carrying capacity of agriculture goes brrr.
And then a century of low child mortality on top of that.
