People Share 40 Creepy Things That They Wish Were Lies But Are Actually Scientific Facts

Basically the entirety of pregnancy/childbirth. Like, this other living organism embeds itself in the lining of my uterus, feeds off my blood, makes me grow an entirely new organ (the placenta) just to feed/protect it while it grows, then it comes out while basically still gestating (other mammals babies can walk and run within minutes of birth, ours can’t even hold up their giant domes!) just because the hole I have to push it through won’t be big enough for its head if it stays in any longer.

Oh, and once I’ve done all that I get to have the longest and worst period of my life while my uterus sheds out 40 weeks of uterine lining.

I’ve had a kid and it still f***s me up.

The first AI that can successfully pass the Turing test would be able to pretend that it couldn't.

The sudden urge to jump off of a very high height. You can be physically and mentally stable to the greatest degree and still have this feeling when at such a high height.

Honestly nothing is more creepy than how deep sea anglerfish mate.

The deep sea is dark, and the anglerfish are spread very thinly. Therefore, when an anglerfish meets another anglerfish, it’s incredibly important they get the chance to mate over and over again. The evolutionary strategy that deep sea anglerfish devised is extra creepy. The male latches onto the female, biting her and never letting go. That way he can inseminate the eggs she drops. Not that bad so far right? But wait, how does he eat if he’s latched on his mate?

Well, the circulatory systems fuse and the female provides nutrients for the male through this fused circulatory system. The true horror starts here. The organs of male start to wither and atrophy, being absorbed into the female. Eventually, the male is reduced to a lump of testicles the females use to fertilize their eggs. Females are often covered in bumps of several males that have melted into the female, becoming a literal body horror lump of meat on the female.

Your brain literally creates your own reality and your senses and body just go along with it.

People think the brain sees what the eyes tell it to, but really the eyes pull up an image of blurry colors and dark spots and the brain goes “cool so that’s a tree”

The mantis shrimp can see colors that our eyes aren't capable of perceiving.

Think about that.

What else are we just not capable of sensing?

When you go to get something from one room (or upstairs) and suddenly forget why you went in there. It’s called a boundary event. Usually, if you go back to where you started (through the boundary) you’ll remember it again.

You get and cure cancer in your own body thousands of times a day.....

The universe is unbelievably infinite, while simultaneously unbelievably infinitesimal.

The universe has ~10^22 stars, a rough guess. This is an unfathomably large number for humans to comprehend, but bear with me. There is roughly 100 thousand million stars in our galaxy alone, and there are roughly 125 billion galaxies.

A single drop of water contains ~10^21 H2O molecules, not too far off from the number of stars in the whole universe. A very similar number, but contained in a single drop of water!

It blows my mind that the universe can contain such mind boggling numbers of things on such wildly different scales. There is so much to reality that the human mind just isn't capable of grasping.

If you believe strongly enough that you have been cursed, your brain can shut itself off entirely in severe cases. The psychological term for it is "Voodoo Death Syndrome." It's just the fact you can literally think yourself to death that unsettles me so.

Caterpillars turn completely into goo in their cocoon, and then become a butterfly.

MarnerIsAMagicMan added:

And there is evidence they retain memories from their pre-goo days. Memories of strong positive/negative stimuli that they show preference-for/aversion-to, even after metamorphosis.

That so many vegetables came from the same plant. Broccoli, kale, kohlrabi, Brussels sprouts, cabbage, etc. They are, botanically speaking, the same species. Humans have just bred them to emphasize different traits (buds, leaves, tubers...) Imagine if humans were as genetically flexible. Imagine a person walking around with GIANT toes, but otherwise normal.
Actually, plant genetics in general is a weird, weird world.

Violets secrete a chemical that causes you to forget what they smell like afterwords. You’re essentially getting roofied every time you sniff one.

When the Titanic sank non of the shoes decomposed so there’s tone of shoes at the bottom of the ocean.

A gamma ray burst could wipe out all life on earth instantly with no warning.

That as the permafrost melts, a lot of locked up methane will be released, and microorganisms there will "wake up" and do their jobs, breaking down organic matter, and release more methane and greenhouse gases.

Your brain is making decisions before you are even aware of the decisions it has made. It also makes decisions based off of learned behavior and you just go along with it.

Humans are bioluminescent (nothing to do with body temperature). We emit visible light that can be photographed in specific conditions. But, this light isn't visible to us. Which makes it a strange thing to have evolved, and begs the question

"what organisms is this light visible to, and why?"

Edit: Adding an edit for all the comments explaining evolution... Please read the thread before commenting. I find this a creepy fact due to implications on interspecific relationships, NOT because I think prehistoric humans went shopping for a bioluminescent hat with a specific motive in mind.

The brain can play tricks on you:

When you look at a clock and the second hand seems to freeze for a moment, your brain is actually generating a false memory - and your perception of time stretches slightly backward.

This effect is called chronostasis.

Parasites can live anywhere inside of you, for years unnoticed. A simple migraine could be a tapeworm crawling in your brain, causing damage.

Your eyes begin to blur frequently and you don't know why and it's not getting better.

Losing weight and having diarrhea but it's not a stomach bug. Well, I guess it is...

You are having a difficult time catching your breath and your chest doesn't feel right.

It could just be some parasite hanging out, using you.
