So are you going to tell us about the giant hyperpredatory sperm whales or do I have to go google some nightmares myself?

we’re all familiar with the Sperm Whale of our modern seas, largest of the Toothed Whales! it’s also completely specialized for eating squid and squid ONLY, a comfort to anyone who’s ever managed to get just a bit too close to those enormous razor jaws.

but this was very much not always the case! the earlier members of the Sperm Whale lineage were much less… discerning.

early Sperm Whales all resembled our friendly modern swimming school bus to some degree, but the main difference was in the jaws- early Sperm Whales like Acrophyseter and Zygophyseter all had wide, powerful jaws with ENORMOUS teeth suitable for snacking on fish, dolphins, aquatic sloths, and pretty much anything else they could fit down their enormous gullets, kind of like a modern Orca.

and from 12 to 7 million years ago, these things RULED the seas. Megalodon who?

but the greatest of these was Livyatan Melvillei, which was the size of our modern Sperm Whale. 

reaching up to 60 feet long and weighing well over 60 tons, it this thing was a Sea Monster in every sense of the word. 

it is so BONKERS huge that they named it after the Hebrew name for the Biblical Leviathan (and also Herman Melville, who would have gotten a real kick out of it). I cannot overstate how unsafe it would be to share an ocean with this thing. Moby Dick would have been an entirely different book if it was still around. 

so what does a 60-feet hyperpredatory whale eat?

*Groucho Marx voice* WHY, ANYTHING IT WANTS. 

(but mostly other whales.)

Livyatan spent most of its time cruising around looking for delicious smaller whales to shove into that nightmare maw up there, a lifestyle choice we call macroraptorial. though in a pinch, anything else would also do. 

(basically, if you were a mid-sized baleen whale in the paleozoic seas you were just SHIT out of luck, between Megalodon and this thing.)

Livyatan may have died out as little as 5 million years ago, meaning it might even have been around to make the early ancestors of Orcas regret their life choices! (Livyatan is the only animal that could possibly make an Orca regret anything, but God, at what cost)

but die out they did, and that’s probably a good thing for us. why don’t we all just take a moment to really appreciate our modern hyperspecialized Sperm Whales, especially the part where they don’t eat us!

Aquatic sloths?

[bevismusson]

Thalassocnus. Got pretty big, between 2 and 3 meters long. Used their claws to walk across the sea floor.

rb this with ur opinion on this shade of pink:

[inkwingart]

This is magenta, and not pink. Unlike pink, magenta doesn’t actually exist. Our brain just invents magenta to serve as what it considers a logical bridge between red and violet, which each exist at opposite ends of a linear spectrum.

TL;DR this color is fake (and also I hate it)

Wait til you learn about Stygean Blue

[pyrrhiccomedy]

Your brain is a badly-designed hot mess of bootstrapped chemistry that will tell you that all kinds of shit is happening that has no correlation to physical reality, including time travel. It just makes things up. Your brain is guessing about what’s happening when your eyes saccade, what’s happening in your blind spot, and what the majority of the visible light spectrum looks like, and you don’t know it’s happening because it doesn’t aid your survival to become aware that a lot of what you see is fake.

The human eye only has three types of color sensitive cones, which detect red, blue, and green light. Your brain is making up every other color you perceive.

Let’s have a little fun with that thought. This is the visible spectrum of light.

You will of course note that yellow is on the chart. Yellow has a discreet wavelength, and is therefore a distinct physical color. But we can’t see it.

“Sorry, what the fuck?”

What we call yellow is just what our brain shrugs and spits out when our red and green cones are equally stimulated. We have light receptors that can pick up on the physical spectrum of light we call yellow: that’s why yellow things don’t just look like moving black blocks to us. But your brain has no fucking idea what the color yellow looks like. 

Some animals have eyes that can perceive the color yellow! Goldfish have a yellow cone in their eyes. If they could talk, they could tell us what yellow looks like. But we wouldn’t be able to understand it.

What your brain actually sees of the color spectrum:

We can measure the wavelength of light, so we know that when we see ‘yellow,’ we are seeing light in that 550-ish nanometers range. But we don’t have a cone in our eyes that can pick that up. Your brain just has a very consistent guess about what color that wavelength of light could be. We decided to name that guess ‘yellow.’ We can’t imagine what yellow really looks like any more than a dog can imagine the color red.

Here’s the funny thing: your brain is never perceiving just one photon of light at a time. Something like 2*10⁸ photons per second are hitting your retina under normal conditions. Your brain doesn’t individually process all of them. So it averages them out. It grabs a bunch of photons all coming from the same direction, with the same pattern, and goes, “yeah, that cup is blue, fuck it, next.”

That’s how colors blend in our eyes. So sure, if a photon of light with a wavelength of 550 nanometers bounces into our eyes, we see what we call “yellow.” But if we see two photons at the same time, coming from the same object, one of which is 500 nms and the other of which is 600 nms, your brain will average them out and you will still see yellow even though none of the light you just saw was 550 nms.

So how does magenta factor into this?

Well, as we’ve just established, when your brain sees light from two different slices of the visible light spectrum, it will try to just average them together. Green plus red is yellow, fuck it. If it’s more red than green, we’ll call that ‘orange.’ Literally who gives a shit, we’re trying to forage over here. There are bears out here and it’s so scary.

What happens if you take the average of blue and red light, which we perceive to be magenta? What’s the centerpoint of that line?

Fucking green.

Hey, that’s not gonna work? We live on a planet where EVERYTHING IS GREEN. If something is NOT green, that means it’s either food, or a potential source of danger, and either way your brain wants you to know about it.

So your brain goes, WHOOPS. Okay - this is fine. We already made up yellow, orange, cyan, and violet. We’ll just make up another color. Something that looks really, really different from green. 

And so it made up magenta.

So, physics-wise, is magenta “real?”

No; there’s no single wavelength of light that corresponds to magenta. But you’re rarely seeing only a single wavelength of light anyway. And even when you are, every color other than RGB is a dart thrown on the wall by your meat computer. This is the CIE Chromaticity Diagram:

Explaining this thing is a little more than I want to take on on a Saturday morning, but I’ve included a link above that goes into it a little more. The point is that only the colors that actually touch the ‘outline’ of the shape actually correspond to a specific wavelength of light. All of the other colors are blends of multiple wavelengths. So magenta isn’t special.

Given that color is just a fun trick your brain is playing on you to help you find food and avoid danger, is magenta real?

Yeah, absolutely. Or at least, it’s just as real as most of what we see. It’s what we see when we mix up blue and red. It would be disastrous from a survival standpoint to perceive that color as green, so we don’t. Because it’s not green. Light that’s green has a wavelength of around 510 nm. Stuff that’s magenta bounces back light that is both ~400 and ~700. Your brain knows the difference. So it fills in the gap for you, with the best guess it has, same as it does with your blind spot.

The perception of color exists within your brain, and your brain says you see magenta. So you see magenta.

An unstoppable force

and an immovable object meet

but they are holding hands

.

An unstoppable force

and an immovable object

go grocery shopping,

and the unstoppable force

gets the eggs and milk

while the immovable object

feels up avocados and peaches

in the produce section

.

The unstoppable force

and the immovable object

take turns being unstoppable

and immovable,

take turns being forces

and objects and girls,

take turns behind the wheel

on long drives

.

The unstoppable force

makes the best hummus

and the immovable object

makes the best meringues

Their lives are filled

with little cookie crumbs

and dishes left till morning

.

The unstoppable force

and the immovable object meet,

and they call it impossible,

they call it inevitable,

they call it nothing

because it just is

It’s a hypothetical until it’s not

It’s a frictionless sphere

in a perfect vacuum, but

then how can I hear you

turning in the night?

.

A unstoppable force

and an immovable object meet

and they say, you.

I will move for you.

I will move the earth

for you.

all these men want casual no strings attached relationships then wonder why they keep slipping into pits of like sorrow and intermittent depression in the moments they’re too sober. Like when all you’ve done is compartmentalize affection to the point where it’s just a transaction to you, or a point of maintenance you have to fulfill every few nights, you *will* suffer consequences. your heart *will* eventually feel heavy when you start to remember all your missed connections, and all the opportunities to feel genuine love for another person. like this sort of selfishness comes with a price, there’s like a debt to be paid here

Social media has really done a number on my perception of human (especially female) anatomy. I constantly get upset that my natural waist isn’t sucked in like these girls on Instagram, completely forgetting that ribcages and internal organs exist (as does photoshop and surgery).I tend to view my body as pieces (breasts, waist, hips, thighs) instead of as a whole complete thing. It’s rough because I’ve practically forgotten what a human body is supposed to look like completely unaltered. All I see when I look at my body are flaws
