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."

"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."

"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.

We all have strong opinions about something, but when we think of opinions, we often think of hot button topics like political subjects.

But as it turns out, sometimes we can have just as strong of opinions of our preferred types of pasta.

One of life's most unfortunate moments is when we feel our lives are genuinely in danger.

These horrific moments can involve the behavior of people with malicious intentions or just being at the wrong place and time.

Even though many people live to share their harrowing stories, the trauma doesn't necessarily go away completely.

But all anyone who's experienced a terrifying ordeal can do to find peace is to count their blessings and be grateful they are survivors.

Perhaps the best thing about our friends is that we can always rely on them.

To help us out, to give us words of comfort and wisdom when we need them, or to just be a willing pair of ears.

Even so, our friends still have a way of surprising us, as well as disappointing us from time to time.

Sometimes they'll do things that just make us groan and roll our eyes but are easily forgiven over time.

Other times, however, they might do or say something which can only be described as "f*cked up."

Potentially putting an effective end to your friendship.

When you gotta go, you go.

That should be a mantra for getting rid of the toxic people in our lives.

Not every relationship is meant to last forever.

Some people don't know how to be friends.

They are awfully good at pretending though.

Be vigilant of the signs and red flags.

Toxic people are crafty.

And once you're free, never look back.
