Our universe is filled with an infinite amount of unexplained mysteries yet to be explored.
And yet, the limited number of substantive facts we are cognizant of still continue to baffle us.
For instance, did you know the Eiffel Tower can be 15 cm taller in the summer because of thermal expansion? Or that polar bears are nearly undetectable by infrared cameras due to the thickness of their coat and skin?
But along with those rather "cool" facts, there are just as many that are truly unsettling.
Curious to find out what facts can give you the heebie-jeebies, Redditor aelmnnor asked:
"What's a scientific fact that creeps you out?"
Creepy Species
If you apply these entities' characteristics towards human beings, you will have the makings of a horror movie.
Goodbye Siblings
"Obligate siblicide. In some species of animals, multiple offspring are born but only one is actually raised by the mother. The others are born only as backup in case the first-born doesn't survive. When the first-born is fine, which is the typical case, it kills the others."
"Body Horror Lump Of Meat"
"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."
Stomach This
"Sea stars eject their stomachs to cover edible parts of their prey, begin digesting it externally, and then pull the partially digested prey into digestive glands to finish the job."
The Eternal Void
"Rogue black holes. There are black holes that just are floating around in space and potentially f'king up solar system just by passing through it."
– Xiagax
Plants Are Weird
"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."
A Persistent Virus
"Doctors/ scientists are BARELY keeping up with the influenza virus. It keeps on mutating rapidly. It really wants to get inside you."
– [deleted]
Goo-bye
"Caterpillars turn completely into goo in their cocoon, and then become a butterfly."
"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."

Our Body Is A Wonderland
Our soul occupies a shell that is a community of tons of other autonomous elements. We truly are merely passengers. Go ahead, ask your brain.
Body Language
"A fever is your body way of saying:"
"We dont negotiate with terrorists! We either destroy the enemy or we die with them!"
– Knork14
Following Our Brains
"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."
Always Being Punk'd
"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."
Why Do Our Faces Itch? This
"That there are little crab-like things crawling on your face."
Take A Breather
"Thinking about how breathing and lungs work freaks me out. Once I start thinking about it all I can think about is my breathing and then I have to force myself to stop thinking about it."
DNA Mutations
"Some mutations of just one letter in the DNA code can kill the fetus almost instantly, but some people live and have a seemingly healthy life while missing a whole chromosome. If you understand anything about biology, that's completely wild."
Invisible Light
"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."
Our Breathing Apparatus
"Thinking about how breathing and lungs work freaks me out. Once I start thinking about it all I can think about is my breathing and then I have to force myself to stop thinking about it."
Ominous
Hints of death abound in these unsettling facts.
Tragic Remains
"When the titanic sank non of the shoes decomposed so there's tons of shoes at the bottom of the ocean."
– Dref27
This Sucks
"There is something called 'the squeeze,' where when people had old scuba suits with tubes, you could actually get sucked into that tube if the pressure was off. You are literally shredded through your own breathing tube."
The Urge
"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."
Always In Battle
"You get and cure cancer in your own body thousands of times a day....."
"Your body produces thousands and thousands of cells with damaged dna. It's a bit of exaggeration to call them cancer but if any of these cells were to survive they could become cancerous. Your immune system destroys them before they get to that point. This is also why if you were to live forever you would eventually get cancer because the chances of your body missing them statistically increases. This occurs thousands upon thousands upon thousands of times a day."
Based on the factoids that just invaded your brain, truth is sometimes stranger than fiction.
One factoid that kept me up at night was reading about a woman in 2015 who suffered from headaches. It turned out the source was a brain tumor – one that resembled skin and had bones, teeth, and hair.
The rare mass was called a "teratoma," and doctors confirmed it was not a "twin," but germ cells that had fallen off when the woman was an embryo and wound up on an abnormal place – her brain – and continued to develop along with her.
If the woman heard voices in her head – as some of us figuratively experience – it might have literally been because she had a mouthpiece growing inside her brain.
Ahh, the mysteries of life.

Teachers are meant to impart knowledge to the next generation, but they have to get the kids to pay attention first.
Not an easy task.
So many, too many schools are plagued by kids who have no self-control.
Teachers end up playing referee, counselor, and parent in addition to their teaching role.
All of those additional hats don't come with any additional pay.
It's no wonder we're in a teacher shortage.
Redditor _Planet_Mars_ wanted the teachers out there to share some rough student stories, so they asked:
"Teachers, what is the worst thing you've seen a student do?"
I once saw a kid drive their car into the school office.
They were drunk.
Thankfully no one was injured.
POP!
"The was a loud pop and a flash in the back corner of the classroom. I asked the student sitting there what happened. She said it was firecrackers. I sent her to the office. While she was still in the office, I realized the electrical outlets in the room didn’t work. At that point, another student fessed up that the student sent to the office had put a pair of scissors in the outlet. I’m not sure why that student thought it was better to lie and claim she was doing fireworks inside the school?"

Pain
"When I was teaching preschool, I had a little girl, between 3-4, walk up to another girl who was sitting on the rug reading a book, grab her by the hair and slam her head into the wall. They hadn’t been interacting in any way prior. When I asked her why she did it, she said she 'wanted her to know it hurts.'"
No-Doubt-8748
That Kid
"A different type of bad than most of these."
"I was a teacher at a poor inner-city school. I had a lot of wonderful students but some difficult ones. One was the worst — bright but was always sleeping through class and acting up and never doing homework. I lived about 30 minutes away. One night, I stopped by the local Wawa after a night out with friends. Was at least 11:30 pm and I was already dreading the early morning drive to school. And who should be checking me out but my own 'problem' student."
"He was working late to make money for his family and then getting home at 1:00 am or later before heading into school on 4-5 hours of sleep. He was a smart kid. Really smart. I hope things worked out for him but I can’t help but wonder what would have happened if he’d been allowed to have a childhood and focus on his education."

"It gets very hot here in the warmer months and so the school put out those big containers for water for everyone. Well, one student was caught peeing into a bag and dumping it into the containers."

Some kids really need some deeper therapy.
Peeing in bags? Seriously?!

"My wife is an elementary teacher and has a kid this year that likes to slip under their desk and lick toes (we live in a warm state) and they all think he will grow up to be a creeper."
CherryManhattan
BOOM
"This was the worst thing I know of that happened at my high school."
"Someone brought a blasting cap to school (OK, that's a bit dumb), and flushed it down the toilet (that's REALLY dumb). Then told a teacher about it, because maybe it wasn't such a good idea (their best idea that day, really)."
"Wound up with that restroom being taken out of service while the fire department x-rayed the plumbing to find and remove the (admittedly tiny) explosive. Took several weeks before it was back in service."

Sad
"My favorite teacher in high school was a very kind a lenient man. Do your work, be respectful, and follow the major school rules and you and him would be cool. The one thing that would seem minor, but that he was very strict about was taking any medication in any way shape, or form in his classroom."
"One day, I needed to take some Advil for cramps and asked to take it. He said I needed to go to the nurse for permission. I ended up asking him why he was so strict about it. it turns out, he had a student pass out in class one day at his former school. He tried to wake her up and called the nurse, but she wouldn't wake up. They called 911 and by the time they got there, she had died of an OD on narcotics she took in the bathroom that she had hidden in a Tylenol bottle. I don't know how he went back to teaching after that."

Kids are brutal.
No wonder people home school.
Buying a home is a daunting task, but it comes with the comfort of finally having a place to call your own after the lengthy process of purchasing.
One of the things new homeowners look forward to is renovating certain areas of their newly acquired domicile.
However, embarking on this next phase of making a home their own can come with some surprises.
For example, doing a gut reno in the basement or tearing down a non-load-bearing wall can unearth unusual relics left from the previous homeowner.
These discoveries can either be treasures, or something very unpleasant.
Curious to hear from new homeonwers, Redditor Oblivious_Dude14 asked:
"People who bought a house. What is the weirdest thing you have found left by the previous owner?"
These will spark curiosity about former occupants.
Hidden Message
"First time I took a hot shower in our new home. The steam covered the mirror, only to reveal the phrase 'HELLO, I SEE YOU' in large finger drawn writing."
"It freaked me out for a second, but made me laugh soon after that."
"It was such an inconspicuous yet obvious thing to leave for the new homeowner (me)."

A Special Request
"It's not really weird but I think it's kind of a nice story."
"One of the kids' rooms has a shelf going all around the top edge, and when my kid was putting stuff up there they found a letter from the previous kid. The letter welcomed them to the room etc and asked them to take special care of a rose bush in the front yard that was their special rose bush. My kid thought it was really cool to have that connection with the previous kid."

Instructions
"Not really weird but they left a typed out and printed note about the house and how to take care of it. Detailing all the plant life in the backyard and how to prep for the winter. Described how to take care of the hot tub and gave random tid bits about the electrical."

Family Treasure
"Before I met her, my wife got a call from someone she worked with saying they'd just bought an old house and in the city, and in it was a steamer trunk with her family name (not a common one) carved into the woodwork on one end."
"As it turns out, it was the trunk that her great grandfather used when he came over from Germany, and it made the trip to my wife's hometown when he met her great grandmother on a visit, and subsequently moved to her city to marry her. We now have it and it's full of family portraits and albums."

Vintage Trickster
"My first house purchase in 2005 - bought an old farmhouse that was built in 1923. The basement was FILLED with crap - we told them they needed to clean it all out before closing, but they didn't do it. The realtor asked if we wanted to postpone closing, and we decided no - some of the stuff looked interesting enough. Maybe it will be worthwhile to go through."
"Most of it was just junk. Then, about half way through (we were working our way from one end of the basement to the other, because you could barely walk through), I went to pick up what I thought was a small box, only to quickly realize it weighed at least 75 pounds. Upon further inspection, it wasn't a box, but a wooden square, 4' wide and about 12'x12', with two thin masonite plywood covers on each side. On one edge were two bolts with wires coming off that had been cut."
"Very strange - had no idea what it was, but thought it was interesting. So I put it aside and we kept going. At the very back of the basement once we cleared everything else out, was a rickety gray cabinet, built into the house. Inside, were numerous strange small tools, vials of mercury, vials of a strange powder, and thousands - literally thousands - of dice blanks. Some actual dice, but mostly blanks without the dots. they were all in little boxes labeled 'dice blanks'. Also very strange..."
"Not too long after that, I met a guy and upon learning my address, he said 'can I come over?My best friend grew up in that house'. He came by, and proceeded to tell me stories for an hour and a half about his childhood best friends eccentric father: Someone who was a part of the 'Dixieland Mafia' in the 60s and 70s, and who made a living traveling around the US as a traveling gambler. The enormously heavy box was an electro-magnet. And the dice blanks were for him to make his own loaded dice with a little bit of metal powder under the inlaid dot, so he could set up his own table with the the electromagnet underneath, and turn it on when he wanted to persuade the dice. He told me many other stories, including that there was 'no doubt in his mind that he had killed someone'. Pretty fascinating."

When my great aunt passed away, our family went over to her and her husband's home in Pomona, CA to clear it out in preparation to sell.
They emigrated from Japan in the late 1930s and brought with them many decorative figurines, sculptures, and wooden carvings from the homeland.
One of the pieces was a kabuki doll on a wooden base. As we were placing the item in a box, a tiny envelope that had been taped underneath the doll's base came loose.
I opened it and found what looked like instructions for something. I kick myself to this day that I didn't keep the letter and never bothered asking my parents what the note said as we were frantically trying to empty the house.
But man, my imagination ran wild. Was it a treasure map? Who knows. I still wonder to this day what the note said and tossing it aside remains one of my life's greatest regrets.

Chemical Engineer
"I had an intern with a PhD once. She was trying to be a chemical process engineer. VERY book smart."
"I spent the Summer teaching her how to use basic tools like screwdrivers and wrenches for simple tasks like opening containers and adjusting clamps. She had zero practical skills and couldn’t figure anything whatsoever out on her own."
"She’d get lost in a building and call me and I’d tell her to find the exit, but she’d get lost inside and we’d have to go in and get her. This routinely happened, and she would just find somewhere random and sit until we collected her."
"When her car’s GPS lost signal once she didn’t know what to do so she stopped in the middle of the road and texted me where she was and that there was something wrong with her car and to come help. I figured there was a breakdown or something based on the text and drove out to check on it because she wasn’t responding."
Giphy"She was crying sitting on the side of the road and a cop was yelling at her to move her car which was still in the lane."
"If you told her to pick something up from a store she’d ask where it was and if you didn’t know, she would never find it "She refused to ask an employee because she knew they weren’t as smart as she was."
"She’d just walk in random directions looking for things. For example if you said 'go to Walmart and find some work boots because you lost yours' she would send me pictures of random aisles in Walmart with 'is this close? which way from here?'.”

GiphyIt's Not Rocket Science...
I chuckle whenever someone uses this saying to indicate something isn't complex like rocket science ever since my friend became an aeronautical engineer.
Why?
Well, we'd have to go back to the mid-1980s when we were both teenagers in high school. As many teens with cars in rural America did, my friends liked to drive around on the back roads as a form of entertainment.
One sunny, Summer day two of my friends came to visit me with a tale to tell.
It seems they were driving on a stretch of road with a speed limit of 35mph [56kph] because of a cluster of homes and farms. When the car slowed to this speed, Mr. Future Rocket Scientist looked down at the pavement passing by below his window on the passenger side.
Upon studying the passing blacktop for several moments, he came to the conclusion he could easily run as fast as the car was moving, so...
...he undid his seatbelt, opened the car door and STEPPED OUT of the moving car.
According to the driver, one moment our friend was sitting next to him and the next he was gone. Or mostly gone.
After a brief moment of panic during which he slowed then stopped the car, he noticed Mr. Future Rocket Scientist's right hand gripping the door's armrest and his left hand gripping the side of the passenger seat.
He was probably only dragged for a few seconds which wasn't long enough to do more than scuff up his jeans, jean jacket and the toes of his shoes.
He escaped with only minor road rash and a few bruises.
After the driver told me what happened from his perspective, Mr. Future Rocket Scientist interjected:
"It worked!"
"I was doing really well until I tripped over that rock."
Luckily an understanding of things like velocity, speed, trajectory, friction, drag, inertia and gravity aren't needed for aeronautics.
GiphyNeedless to say, we've never let him forget his "experiment."
He still claims the only problem was that rock on the road.
And I now use the saying "it's not rocket surgery" instead of either of the original sayings.
