People Confess Which Scientific Fact Scares Them To the Core​ The Core

I've never been a science fan.

I accept it as revolutionary and a part of life but I've misunderstood so much of it.

I just accept my lack of understanding and move on.

And in hindsight I may have done myself a favor.

Science is riddled with drama and fear.

Redditor bck83 wanted to hear from everyone about all the reasons science can be more terrifying than fun. They asked:

"What scientific fact or theory scares you to your bones?"

Science and math... two of my school career enemies. Educate me on what I don't want to know.

"There have already been five mass extinction level events."


"And cockroaches survived all of them..."



"Naegleria fowleri (brain eating amoeba) has a 97% fatality rate and it’s immune to most antibiotics."


"It's a disease that literally infects and kills neurons. This is not on the treatment, this is just how rabies work."

"Many other neurological infections leave people brain damaged, many neurological conditions that have nothing to do with infections do too. Just like having endocarditis is likely to give you heart damage, a disease that infects the brain is likely gonna leave you brain damaged. It's not a perfect treatment by any means, but it is there, and writing it off is neither fair nor accurate."


The Unknown

"Quite a common one, but space is SO BIG. Like, bigger than the amount that we can observe. Gives me the chills."


"And in all that we see, the entire universe seems to be entirely hostile to life - as in instant death. Temperatures, radiation, poison gases, vacuum. All of it is quickly fatal, except for this little pale blue dot. If there are any other pale blue dots out there they are probably very rare, and impossibly remote."


Farewell to the mind...

"Alzheimer's/Dementia - anything where you lose your memory or become a burden to your family."


"My dad has dementia and it's a constant cycle of adapting to the new reality and then noticing a new or enhanced symptom and having to adapt to that."

"I think it feels like when old cartoon characters are walking over a cliff and keeping on walking until they realize there's nothing under their feet anymore. I love my dad. He is only in his fifties and I don't think he'll remember who I am when I get married. He doesn't know what chess is anymore but he can play it really well. Dementia is a weird thing."

"There are between 6-10 nuclear missiles that are missing. No sovereign nation has a clue where they are, or who has control of them."


They always said science is fun. Clearly that was a lie.

All of it...

"Your brain recalls memories when you die but your brain also recalls memories wrong so you're basically lying to yourself right before you die."


Any second...

"I suppose that at any moment you can have an aneurysm and bam you're dead and there's not much you can really do to prevent it or even predict it."


"Would just like to add, sometimes you don’t die. My mother didn’t. 4 weeks ago she went into surgery to repair the aneurysm."

"She’s been in the hospital ever since, sleeping most of the time and generally confused and not knowing where she is the rest of the time with only very very rare moments of apparent lucidity. She has an NG tube and is currently bedridden. It is horrible. We don’t know if she’ll ever get better."



"It's thought our galaxy is full of rogue planets wandering free from their original star. At any time one of these planets could wander through our solar system radically throwing off the fragile balance of our orbits. A big enough planet passing close enough could send us careening into the sun."


The Resistance

"Antimicrobial resistance. What's really crazy is, we owe our modern prosperity (especially in the US) to antibiotics. Each particular antibiotic only works for a short period of time, before pathogenic bacteria becomes resistant to it. We've been though numerous different antibiotics since the discovery of penicillin, and pathogenic bacteria have become resistant to almost all of them."

"We're running out of antibiotics that are still effective. About 4 or 5 years ago, I learned that there were babies born in India who had infections that were resistant to all known types of antibiotics. There's a good chance that in our lifetimes, we'll see people dying from common infections due to the lack of effective drugs to treat them."



destruction GIFGiphy

"The theory of MAD, or mutually assured destruction. It's a great theory for helping me sleep at night, but uh... It kinda only works if everyone involved is always rational at all times, and never feels they have nothing to lose."

"Thankfully no human ever acts irrationally. And certainly if they did, we'd never let them keep control of nuclear weapons! That'd be insane. Ha ha. Really insane. Like, 'insane"'is honestly Putin it mildly."


Know it All...

"The fact that we will never ever be able to know everything. like theres a limit to what we can know and theres so much out there that will we just never discover. Another one that scares me is that we are all alone on this floating rock. I doubt we are the only intelligent life in this universe but its possible that we are in a sense and that it self scares me so much."



"There are microorganisms and bacteria crawling around your eyes. Academically, I know that we think they are helpful and fight disease. However, I don't like the notion of stuff crawling around in/on my eyes."


"Not just eyes, inside our gut systems and covering our skin. There are microorganisms on everything all the time. But don't worry, most of them are our friends! :)"



"When you get rabies and didn't get treated until the symptoms show up, you're dead. When you experience single symptom of rabies you're already dead, there's nothing you can do about it. Also rabies symptoms can take long to show up, the incubation period for rabies can last up to years. So if you were bitten or scratched by an animal with rabies years ago, the symptoms could show up right now and you will die."



Cat Internet GIF by TJ FullerGiphy

"Gamma blasts scare the crap out of me they could happen at any time and nothing can stop them."



"Atoms are 99.99% empty space. The nature of all seemingly solid matter is an illusion."


"You also never REALLY touch anything. There is always an incredibly small space between you and an object, even if you push on it, due to electrostatic repulsion between your body's atoms and the atoms of the object. We just 'feel' it, due to electrical charges in our nerves. So, we never touch anything, but we 'feel' it in our brain."


False Truths

"It is possible that the universe exists at a false vacuum level and at some point, any time or anywhere, vacuum decay could occur, sending a wave of destruction out in every direction. The only solace is that if it did occur, it would probably spread at no greater than the speed of light, so if it occurred in some other galaxy, humanity would be long gone before it reached here. Of course, that also means it could have already occurred in multiple places and at multiple times and the universe is just being destroyed bit by bit."


It's Grim

"There is a thought that if there were a big enough landslide on the Canary Islands (which is a real possibility), if it were large enough it'd cause a giant tsunami causing significant damage to the Eastern United States. I've seen some of the models, they look quite grim."



"The Dark Forest Theory. It’s an explanation as to why we haven’t heard back from aliens yet. They are purposely keeping quiet as there is no way to know if another life form may perceive you as a threat and decide to kill you off. Whoever pulls the trigger first is the winner. Everyone is a hunter. So, why risk reaching out?"



Too Much GIF by Satish GaireGiphy

"That humanity has changed so drastically in the last 100 years that it scares me how different life will be in even 50 years from now."


"shutting off"

"Lots of people don't just pass away quickly. A lot of times they experience their organs 'shutting off' basically one by one. A common experience is your lungs filling with fluid and causing you to suffocate. Maybe death itself isn't too bad, as it is the ultimate peace: a release from the suffering of life. The part I'm most afraid of is the process of dying and what it will all feel like."

"If I'm old and at the point where doctors are certain i cannot live much longer, id hope they come up with something thats not totally agonizing. Since that is many, many years in the future it'll hopefully go smoothly with advancements in medicine and tech."


I need better news in this day and age.

Forget science... I'm sticking with Drama.

People Reveal The Weirdest Thing About Themselves

Reddit user Isitjustmedownhere asked: 'Give an example; how weird are you really?'

Let's get one thing straight: no one is normal. We're all weird in our own ways, and that is actually normal.

Of course, that doesn't mean we don't all have that one strange trait or quirk that outweighs all the other weirdness we possess.

For me, it's the fact that I'm almost 30 years old, and I still have an imaginary friend. Her name is Sarah, she has red hair and green eyes, and I strongly believe that, since I lived in India when I created her and there were no actual people with red hair around, she was based on Daphne Blake from Scooby-Doo.

I also didn't know the name Sarah when I created her, so that came later. I know she's not really there, hence the term 'imaginary friend,' but she's kind of always been around. We all have conversations in our heads; mine are with Sarah. She keeps me on task and efficient.

My mom thinks I'm crazy that I still have an imaginary friend, and writing about her like this makes me think I may actually be crazy, but I don't mind. As I said, we're all weird, and we all have that one trait that outweighs all the other weirdness.

Redditors know this all too well and are eager to share their weird traits.

It all started when Redditor Isitjustmedownhere asked:

"Give an example; how weird are you really?"

Monsters Under My Bed

"My bed doesn't touch any wall."

"Edit: I guess i should clarify im not rich."

– Practical_Eye_3600

"Gosh the monsters can get you from any angle then."

– bikergirlr7

"At first I thought this was a flex on how big your bedroom is, but then I realized you're just a psycho 😁"

– zenOFiniquity8

Can You See Why?

"I bought one of those super-powerful fans to dry a basement carpet. Afterwards, I realized that it can point straight up and that it would be amazing to use on myself post-shower. Now I squeegee my body with my hands, step out of the shower and get blasted by a wide jet of room-temp air. I barely use my towel at all. Wife thinks I'm weird."

– KingBooRadley


"In 1990 when I was 8 years old and bored on a field trip, I saw a black Oldsmobile Cutlass driving down the street on a hot day to where you could see that mirage like distortion from the heat on the road. I took a “snapshot” by blinking my eyes and told myself “I wonder how long I can remember this image” ….well."

– AquamarineCheetah

"Even before smartphones, I always take "snapshots" by blinking my eyes hoping I'll remember every detail so I can draw it when I get home. Unfortunately, I may have taken so much snapshots that I can no longer remember every detail I want to draw."

"Makes me think my "memory is full.""

– Reasonable-Pirate902

Same, Same

"I have eaten the same lunch every day for the past 4 years and I'm not bored yet."

– OhhGoood

"How f**king big was this lunch when you started?"

– notmyrealnam3

Not Sure Who Was Weirder

"Had a line cook that worked for us for 6 months never said much. My sous chef once told him with no context, "Baw wit da baw daw bang daw bang diggy diggy." The guy smiled, left, and never came back."

– Frostygrunt


"I pace around my house for hours listening to music imagining that I have done all the things I simply lack the brain capacity to do, or in some really bizarre scenarios, I can really get immersed in these imaginations sometimes I don't know if this is some form of schizophrenia or what."

– RandomSharinganUser

"I do the same exact thing, sometimes for hours. When I was young it would be a ridiculous amount of time and many years later it’s sort of trickled off into almost nothing (almost). It’s weird but I just thought it’s how my brain processes sh*t."

– Kolkeia

If Only

"Even as an adult I still think that if you are in a car that goes over a cliff; and right as you are about to hit the ground if you jump up you can avoid the damage and will land safely. I know I'm wrong. You shut up. I'm not crying."

– ShotCompetition2593

Pet Food

"As a kid I would snack on my dog's Milkbones."

– drummerskillit

"Haha, I have a clear memory of myself doing this as well. I was around 3 y/o. Needless to say no one was supervising me."

– Isitjustmedownhere

"When I was younger, one of my responsibilities was to feed the pet fish every day. Instead, I would hide under the futon in the spare bedroom and eat the fish food."

– -GateKeep-

My Favorite Subject

"I'm autistic and have always had a thing for insects. My neurotypical best friend and I used to hang out at this local bar to talk to girls, back in the late 90s. One time he claimed that my tendency to circle conversations back to insects was hurting my game. The next time we went to that bar (with a few other friends), he turned and said sternly "No talking about bugs. Or space, or statistics or other bullsh*t but mainly no bugs." I felt like he was losing his mind over nothing."

"It was summer, the bar had its windows open. Our group hit it off with a group of young ladies, We were all chatting and having a good time. I was talking to one of these girls, my buddy was behind her facing away from me talking to a few other people."

"A cloudless sulphur flies in and lands on little thing that holds coasters."

"Cue Jordan Peele sweating gif."

"The girl notices my tension, and asks if I am looking at the leaf. "Actually, that's a lepidoptera called..." I looked at the back of my friend's head, he wasn't looking, "I mean a butterfly..." I poked it and it spread its wings the girl says "oh that's a BUG?!" and I still remember my friend turning around slowly to look at me with chastisement. The ONE thing he told me not to do."

"I was 21, and was completely not aware that I already had a rep for being an oddball. It got worse from there."

– Phormicidae

*Teeth Chatter*

"I bite ice cream sometimes."


"That's how I am with popsicles. My wife shudders every single time."


Never Speak Of This

"I put ice in my milk."


"You should keep that kind of thing to yourself. Even when asked."

– We-R-Doomed

"There's some disturbing sh*t in this thread, but this one takes the cake."

– RatonaMuffin

More Than Super Hearing

"I can hear the television while it's on mute."

– Tira13e

"What does it say to you, child?"

– Mama_Skip


"I put mustard on my omelettes."

– Deleted User


– NotCrustOr-filling

Evened Up

"Whenever I say a word and feel like I used a half of my mouth more than the other half, I have to even it out by saying the word again using the other half of my mouth more. If I don't do it correctly, that can go on forever until I feel it's ok."

"I do it silently so I don't creep people out."

– LesPaltaX

"That sounds like a symptom of OCD (I have it myself). Some people with OCD feel like certain actions have to be balanced (like counting or making sure physical movements are even). You should find a therapist who specializes in OCD, because they can help you."

– MoonlightKayla

I totally have the same need for things to be balanced! Guess I'm weird and a little OCD!

Experiencing death is a fascinating and frightening idea.

Who doesn't want to know what is waiting for us on the other side?

But so many of us want to know and then come back and live a little longer.

It would be so great to be sure there is something else.

But the whole dying part is not that great, so we'll have to rely on other people's accounts.

Redditor AlaskaStiletto wanted to hear from everyone who has returned to life, so they asked:

"Redditors who have 'died' and come back to life, what did you see?"


Happy Good Vibes GIF by Major League SoccerGiphy

"My dad's heart stopped when he had a heart attack and he had to be brought back to life. He kept the paper copy of the heart monitor which shows he flatlined. He said he felt an overwhelming sensation of peace, like nothing he had felt before."



"I had surgical complications in 2010 that caused a great deal of blood loss. As a result, I had extremely low blood pressure and could barely stay awake. I remember feeling like I was surrounded by loved ones who had passed. They were in a circle around me and I knew they were there to guide me onwards. I told them I was not ready to go because my kids needed me and I came back."

"My nurse later said she was afraid she’d find me dead every time she came into the room."

"It took months, and blood transfusions, but I recovered."


Take Me Back

"Overwhelming peace and happiness. A bright airy and floating feeling. I live a very stressful life. Imagine finding out the person you have had a crush on reveals they have the same feelings for you and then you win the lotto later that day - that was the feeling I had."

"I never feared death afterward and am relieved when I hear of people dying after suffering from an illness."



The Light Minnie GIF by (G)I-DLEGiphy

"I had a heart surgery with near-death experience, for me at least (well the possibility that those effects are caused by morphine is also there) I just saw black and nothing else but it was warm and I had such inner peace, its weird as I sometimes still think about it and wish this feeling of being so light and free again."


This is why I hate surgery.

You just never know.



"More of a near-death experience. I was electrocuted. I felt like I was in a deep hole looking straight up in the sky. My life flashed before me. Felt sad for my family, but I had a deep sense of peace."



"Nursing in the ICU, we’ve had people try to die on us many times during the years, some successfully. One guy stood out to me. His heart stopped. We called a code, are working on him, and suddenly he comes to. We hadn’t vented him yet, so he was able to talk, and he started screaming, 'Don’t let them take me, don’t let them take me, they are coming,' he was scared and yelling."

"Then he yelled a little more, as we tried to calm him down, he screamed, 'No, No,' and gestured towards the end of the bed, and died again. We didn’t get him back. It was seriously creepy. We called his son to tell him the news, and the son said basically, 'Good, he was an SOB.'”



"My sister died and said it was extremely peaceful. She said it was very loud like a train station and lots of talking and she was stuck in this area that was like a curtain with lots of beautiful colors (colors that you don’t see in real life according to her) a man told her 'He was sorry, but she had to go back as it wasn’t her time.'"


"I had a really similar experience except I was in an endless garden with flowers that were colors I had never seen before. It was quiet and peaceful and a woman in a dress looked at me, shook her head, and just said 'Not yet.' As I was coming back, it was extremely loud, like everyone in the world was trying to talk all at once. It was all very disorienting but it changed my perspective on life!"


The Fog

"I was in a gray fog with a girl who looked a lot like a young version of my grandmother (who was still alive) but dressed like a pioneer in the 1800s she didn't say anything but kept pulling me towards an opening in the wall. I kept refusing to go because I was so tired."

"I finally got tired of her nagging and went and that's when I came to. I had bled out during a c-section and my heart could not beat without blood. They had to deliver the baby and sew up the bleeders. refill me with blood before they could restart my heart so, like, at least 12 minutes gone."


Through the Walls

"My spouse was dead for a couple of minutes one miserable night. She maintains that she saw nothing, but only heard people talking about her like through a wall. The only thing she remembers for absolute certain was begging an ER nurse that she didn't want to die."

"She's quite alive and well today."


Well let's all be happy to be alive.

It seems to be all we have.

Man's waist line

Trying to lose weight is a struggle understood by many people regardless of size.

The goal of reaching a healthy weight may seem unattainable, but with diet and exercise, it can pay off through persistence and discipline.

Seeing the pounds gradually drop off can also be a great motivator and incentivize people to stay the course.

Those who've achieved their respective weight goals shared their experiences when Redditor apprenti8455 asked:

"People who lost a lot of weight, what surprises you the most now?"

Redditors didn't see these coming.

Shiver Me Timbers

"I’m always cold now!"

– Telrom_1

"I had a coworker lose over 130 pounds five or six years ago. I’ve never seen him without a jacket on since."

– r7ndom

"140 lbs lost here starting just before COVID, I feel like that little old lady that's always cold, damn this top comment was on point lmao."

– mr_remy

Drawing Concern

"I lost 100 pounds over a year and a half but since I’m old(70’s) it seems few people comment on it because (I think) they think I’m wasting away from some terminal illness."

– dee-fondy

"Congrats on the weight loss! It’s honestly a real accomplishment 🙂"

"Working in oncology, I can never comment on someone’s weight loss unless I specifically know it was on purpose, regardless of their age. I think it kind of ruffles feathers at times, but like I don’t want to congratulate someone for having cancer or something. It’s a weird place to be in."

– LizardofDeath

Unleashing Insults

"I remember when I lost the first big chunk of weight (around 50 lbs) it was like it gave some people license to talk sh*t about the 'old' me. Old coworkers, friends, made a lot of not just negative, but harsh comments about what I used to look like. One person I met after the big loss saw a picture of me prior and said, 'Wow, we wouldn’t even be friends!'”

"It wasn’t extremely common, but I was a little alarmed by some of the attention. My weight has been up and down since then, but every time I gain a little it gets me a little down thinking about those things people said."

– alanamablamaspama

Not Everything Goes After Losing Weight

"The loose skin is a bit unexpected."

– KeltarCentauri

"I haven’t experienced it myself, but surgery to remove skin takes a long time to recover. Longer than bariatric surgery and usually isn’t covered by insurance unless you have both."

– KatMagic1977

"It definitely does take a long time to recover. My Dad dropped a little over 200 pounds a few years back and decided to go through with skin removal surgery to deal with the excess. His procedure was extensive, as in he had skin taken from just about every part of his body excluding his head, and he went through hell for weeks in recovery, and he was bedridden for a lot of it."

– Jaew96

These Redditors shared their pleasantly surprising experiences.


"I can buy clothes in any store I want."

– WaySavvyD

"When I lost weight I was dying to go find cute, smaller clothes and I really struggled. As someone who had always been restricted to one or two stores that catered to plus-sized clothing, a full mall of shops with items in my size was daunting. Too many options and not enough knowledge of brands that were good vs cheap. I usually went home pretty frustrated."

– ganache98012

No More Symptoms

"Lost about 80 pounds in the past year and a half, biggest thing that I’ve noticed that I haven’t seen mentioned on here yet is my acid reflux and heartburn are basically gone. I used to be popping tums every couple hours and now they just sit in the medicine cabinet collecting dust."

– colleennicole93

Expanding Capabilities

"I'm all for not judging people by their appearance and I recognise that there are unhealthy, unachievable beauty standards, but one thing that is undeniable is that I can just do stuff now. Just stamina and flexibility alone are worth it, appearance is tertiary at best."

– Ramblonius

People Change Their Tune

"How much nicer people are to you."

"My feet weren't 'wide' they were 'fat.'"

– LiZZygsu

"Have to agree. Lost 220 lbs, people make eye contact and hold open doors and stuff"

"And on the foot thing, I also lost a full shoe size numerically and also wear regular width now 😅"

– awholedamngarden

It's gonna take some getting used to.

Bones Everywhere

"Having bones. Collarbones, wrist bones, knee bones, hip bones, ribs. I have so many bones sticking out everywhere and it’s weird as hell."

– Princess-Pancake-97

"I noticed the shadow of my ribs the other day and it threw me, there’s a whole skeleton in here."

– bekastrange

Knee Pillow

"Right?! And they’re so … pointy! Now I get why people sleep with pillows between their legs - the knee bones laying on top of each other (side sleeper here) is weird and jarring."

– snic2030

"I lost only 40 pounds within the last year or so. I’m struggling to relate to most of these comments as I feel like I just 'slimmed down' rather than dropped a ton. But wow, the pillow between the knees at night. YES! I can relate to this. I think a lot of my weight was in my thighs. I never needed to do this up until recently."

– Strongbad23

More Mobility

"I’ve lost 100 lbs since 2020. It’s a collection of little things that surprise me. For at least 10 years I couldn’t put on socks, or tie my shoes. I couldn’t bend over and pick something up. I couldn’t climb a ladder to fix something. Simple things like that I can do now that fascinate me."

"Edit: Some additional little things are sitting in a chair with arms, sitting in a booth in a restaurant, being able to shop in a normal store AND not needing to buy the biggest size there, being able to easily wipe my butt, and looking down and being able to see my penis."

– dma1965

People making significant changes, whether for mental or physical health, can surely find a newfound perspective on life.

But they can also discover different issues they never saw coming.

That being said, overcoming any challenge in life is laudable, especially if it leads to gaining confidence and ditching insecurities.
