For one hour each year, part of Florida and part of Oregon have the exact same time on their clocks.
Sharks have existed long enough as a species to have orbited the entire Milky Way Galaxy - twice.
Sharks are so old that I’ve seen other comparisons, had never seen the milky way one before, that’s very interesting, the other ones I knew is that sharks are older than:
- The rings of Saturn
- Trees
So when sharks first evolved Saturn had no rings and trees didn’t exist yet.
Sharks preceding trees is 🤯
when sharks first evolved Saturn had no rings
Or at least, didn’t have its current rings. I could be wrong but couldn’t it have torn apart other moons to create a different set of rings that then degraded over time?
Trees are 385 million years old. Sharks are 200 million years old. Trees still out-date sharks.
Worth pointing out that this is the shark lineage and not modern sharks. Sharks have evolved a lot over the last several hundred million years
In the same sense, jellyfish are older than sharks, and sponges are the oldest still-extant animal lineage. Or just sounds cooler to say sharks
no it’s this one named gary and he’s a dick. you know, mean shark gary?
Sharks have existed long enough as a species to have orbited the entire Milky Way Galaxy - twice.
Now that’s cool.
They are older than trees. The very concept of trees.
Trees are 385 million years old. Sharks are 200 million years old. Trees still out-date sharks.
Although… Trees have evolved multiple times in Earth’s history… So sharks are certainly older than certain trees. But not older than the whole tree concept thing.
CORRECTION!!
“Shark” is not a species. A whaleshark is a species. A tigershark is a species. “Shark”, representing multiple species of shark, is a division, specifically the Selachii division.
The Selachii division is 200 million years old. One galactic year for Sol is 225 million years old. This means that sharks, as we know them, have not existed as a division for two galactic years, barely even for one! Horshoe crabs have been around for 250 million years nearly completely unchanged by evolution, so they have been around for one galactic year… But nobody ever seems to talk about them…
Officially, what came before sharks are classified as a different division with “shark-like morphology”, but they aren’t sharks.
Sharks have existed for longer than the North Star, though. So there’s that.
The oldest fossils known are stromatolite fossils from 3.48 billion years ago. There are living stromatolites today. They predate Earth having significant oxygen in its atmosphere, because the cyanobacteria that formed them created the oxygen gas through photosynthesis from carbon dioxide. They’ve orbited the galaxy over fifteen times.
I don’t see it.
Some fun geography one’s.
Maine is the closest US state to Africa.
Alaska is the northern most, Western most, and Eastern most state in the US.My favorite geography one: You get on a plane at Tampa Bay, Florida and fly due south. Which South American countries do you fly over?
Answer is none of them. You miss the entire continent because you are too far west.
It’s close, though. IIRC, you can’t say the same thing about Miami.
My favorite geography fact is that, if you’re on the northern edge of Brazil, you’re actually closer to Canada than you are to the southern border of Brazil.
Makes me think of Texas. Only 1/3 of my trip is getting to Texas. 2/3 is trying to get to where my family is at lol
My favourite geography fact is that when traveling along the Panama canal from the Caribbean sea to the Pacific, you’re further east when you exit than when you entered.
That’s a great one.
Time being a physical dimension in spacetime that can stretch and squish and ‘now’ isn’t the same for every observer is probably the least intuitive one I know
Wibbly wobbly timey wimey
Everything about fecal transplant. Or maybe just the fact that it is even a legitimate medical procedure
“You want my thesis? I hate college!! My thesis is going to be about taking a SHIT up your ASS!”
(Four years later)
“Wow, Mr. Blake! The results of your medical trial were astounding! These are excellent results!”
“Wait…huh?”That really is a shitshow, indeed.
Not fun fact: That’s how I became lactose intolerant
You know, as a society we look down on people who are into poo, but they really do be kind important tbh.
Every single one of us is travelling through space on a tiny speck of dirt, circling a permanent explosion that doesn’t know how to stop itself at 30km/s.
That explosion and multiple specks of dirt besides our own dance around the center of the galaxy in a complex ballet with 200 billion other permanently exploding balls of fire and plasma, many of which are sizeably larger than ours and also have collected pieces of dirt circling around them, at a speed of 200km/s. The center of this agglomeration of giant balls of fire and dirt is a… thing… that is in itself so massive it can’t help eating everything that comes near including suns, light, and the concept of time.And there, travelling around the center of the galaxy at 200km/s, spiraling around your sun at 30km/s, there is you. And somehow you have to work tomorrow.
I was thinking about putting a reference to that in, but decided it would be a bit trite.
So full of it. I don’t work on Saturday.
Despite plants being associated with the color green, chlorophyll is actually a poor absorber of green wavelengths of light.
Hence the reason plants are green, because they absorb the blue and red wavelengths of light, but reflect the green.
That’s just how colour works.
Yep, but it is confusing for many, if not most people. A lot of people simply don’t understand why plant growth lights are pinkish-violet, not green.
I teach art classes. People seem to get it.
And? I talk to non-art students. If you never have to think about it, most people won’t. I promise you, there are plenty of “obvious” topics you are oblivious to and misunderstand. We all have them.
I don’t teach art students, I teach one-off classes to teens and adults.
plant growth lights are pinkish-violet
Really shitty ones are. High quality grow lights use full-spectrum lights including far-red and infrared, and are proven to be more effective than the so called “blurple” temu lights
And you can see sooo much of the infrared and ultraviolet part of the spectrum. What you see is still a kind of pinkish-violet.
By the way, no LED based light is “full spectrum”. That is a common lie. Growth lights have violet-blue LEDs in the 200-400nm range, and red ones in the 600-800nm range.
If you do a spectrum analysis of any LED light, you will see distinctive, narrow peaks around the LEDs core frequencies, usually with a bandwidth of 12-40nm.
For absortion ranges of Chlorophyll A and B, see for example https://www.mpsd.mpg.de/17628/2015-04-chlorophyll-rubio
That’s the case for most things of any colour.
and plants become darker green if they are partially or almost fully shaded.
In other news, the sun is hot!

Bonus fact. A significant amount of sea level rise due to climate change is caused by thermal expansion of the water.
The Kings Chamber in the great pyramid of Egypt maintains an average temperature of 68°F (20°C).
HVAC companies hate this one weird trick! Build a bloody pyramid around your house and you won’t need heat or AC.
I don’t know, that seems kind of right to me.
Kind of like the cheddar cave but for different reasons and different temperatures. Well, actually, the only similarity is regulation.
France is bigger at Christmas than at Easter.
Reason: Pheasant Island.

There are over 100 volcanos on Antarctica
I like this fact and as a geologist I’m a little numb to facts about the Earth. At some level, all land on Earth has a volcanic origin by virtue of us having a molten core, a rigid mantle, and a crusty crust that seeps magma/lava. Time metamorphoses and sediments the rock in different ways. Antarctica just had the misfortune of migrating to the South Pole where millions of years of snow fall lead to its icy encapsulation.
The good news is it’s all melting! Antarctica can be free!
Active or dorment?
Active. Not immediately spewing lava, but they aren’t done.
Also, there’s warm liquid water lakes underneath parts of the antarctic ice as well. And they’re caused by geothermal vents, not global warming
people still believe the moon landing/launches are all cgi made up even to this day, seems very prominent amongst older asians believing in this conspiracy.
Its also very prominent among ignorant morons.
Everything is a conspiracy if you’re too stupid to understand how anything works.
so like, there’s a whole lot of nothing to do out in the boonies. talking about conspiracy theories and making up new ones is fun entertainment. now believing in them? you always got someone who takes shit too seriously and needs to be taken aside, have things explained to. but most of the folk take the stories like you would a radio show, movie, or sermon.
Yeah, most people don’t believe in them. But a concerning amount of people do. I’ve been keeping up with conspiracy people since early 2010s. There’s a huge amount of idiots who take that shit seriously. They are mostly led by grifters who sell snake oil to the morons but some of the leaders are also absolute imbeciles who believe this shit.
Sometimes its genuinely scary how many there are. If I had to guess, I’d say about 15-20% of people believe on one or more stupid conspiracy theory. Thats a LOT.
my mother used to listen to art bell “to laugh at the weirdos” (until i noticed and pointed out the racism in the show) but we did enjoy listening to a good bigfoot or ufo story. especially since my extended family had a bigfoot costume we liked to bust out at family reunions. you had to be in your 40s or… i don’t know what i did to get the secret insider knowledge it was a costume and not actually bigfoot. I think everyone thought i was going to die so i got all the family secrets early.
Yeah I know a few people who like to watch/listen to the conspiracy weirdos for entertainment. And thats fine.
I used to read conspiracy theories in the same way I used to read ghost stories and such. It was just a different kind of fiction, something that felt that it could be real. These days the stupidity is too much and I can’t deal with getting the stuff from the source, I have to use intermediates like Professor Dave Explains, SciManDan, etc youtube channel people.
The average human being has (approximately) one testicle and one ovary.
and less than two arms!
The average human has more than one brain
Hmmm. I don’t beleive this one. I know a lot more brainless people than I know multi-brain people.
Oh you fucke-
Rabbits must eat special poop straight from their butt as a part of a healthy diet.
What about other rabbits’ poop?
I haven’t seen it happen, but I wouldn’t be surprised.
My girl bun does stick her nose up my boy bun’s butt sometimes. But I think that’s just to nip his thighs and get him to move out of her way lol
Oh! I forgot, mama rabbits feed their special poops to their babies. So the answer is, yes, they do eat other rabbit’s poops.
