As if knowledge isn't scary enough, let's her more...

Hello Terry

"Some tumors have teeth, hair and even eyes."

"My sister had one minus the eyes! It was cantaloupe sized on one of her ovaries before it was found. She named it Terry the Teratoma."

Hungry Bacteria

"Brain-eating amoebas."

"My best friend and bunk mate from summer camp died from one of those when I was in 7th grade. Happened so quickly, we were a week into camp and he got really sick. They gave us all heavy meningitis shots because they didn’t know what it was and within a few days he was dead. Turned out to be a brain eating amoeba."

"Edit: strangely enough on the same day he started getting sick one of the lifeguards that was sitting out in a boat waiting for the next group of kids for what we called Trojans Vs. Spartans day had a seizure, fell off the boat and drowned. Only deaths they’d ever had in the 50+ years the camp had been open."

Far Far Away

"The size of our galaxy, how many other galaxies there are and how far away they are. When you can actually see something that incomprehensible.."

Jfonzy

"The nearest star to us would take the Voyager 70,000 years to reach. The nearest galaxy to ours would take the Voyager 749,000,000 years. If we some how managed to take on the monstrous task of speed of light travel it would still take 25,000 years to reach the nearest galaxy. And it's even further apart after you read this. Wild stuff!"

Head Changes

"How the brain is literally rewired and chemically altered by childhood neglect and abuse."

petalumaisreal

"It's genuinely kinda freaky, playing a puzzle game, and noticing how quickly you're getting better at it. The kind of puzzles that were a real blocker in the beginning become baby-easy after like an hour of playing puzzles like it."

LtLabcoat

"My sister faced horrible abuse at the hands of our father, and she has been working through it with multiple therapists over the last 10 years and she is only now starting to get her life back. I feel like she was robbed at a fair chance at life because of our a**hole father."

Awake

"Prions, horrific and totally unpredictable."

geordiesteve520

"Fatal familial insomnia is a prions disease where you can't sleep anymore, you just stay awake until your brain deteriorates and you die."

DrinknEspresso

Now I can never UNKNOW about prions. Perfect.

Days gone by...

"Ageing. I'm content with death but the idea of my body growing old, frail and eventually falling apart before the end game gives me goosebumps."

EvidenceOfInnocence

Bursts

"Gamma ray bursts. No warning, no escape, no defense, no survivors."

Swampwolf42

"If you're talking about supernovas if the star isn't too close the gamma burst would probably only destroy some part of our ozone layer. And gamma radiation is actually the least lethal out of all types of waves."

Sizzle

"Entropy. Time shall consume all things. Inevitable heat death of the universe."

Revolutionary_Elk420

"I personally want the 'Big Crunch' to be true. That instead of fizzling out it all gets sucked back into an infinitely small/dense particle and then another Big Bang happens. It’s my explanation for the multiverse. It’s all one timeline. Just infinitely long."

They're Watching

"More like a theory, the 'orangutan paradox,' when we film a documentary on orangutans, they can’t realize that we are observing them, yet they are the most intelligent species of their category, so aliens might be watching us and we are as oblivious as an orangutan."

Fade 2 Silent

"That hearing is the last sense to leave, when dying."

A blink of an eye

"Deep time. The Earth was alive a million years ago. And a million years before that. A thousand million years before that. Even if our civilization is miraculously successful and we live for 20 thousand more years and colonize thousands of planets like in Dune it's still nothing. A blink of an eye. The Earth would barely notice."

human psychology...

"The scariest thing for me, is that we have scientifically mapped human psychology. We know social habits, and evolutionary survival instincts that we've carried over from our ancient past. We have extensive knowledge on how to elicit the exact response out of a human on command. And the scary thing is that corporations use this information to sell things to us."

"Everything about a product's design from it's shape, to it's color pallet to it's odor is specifically and intricately designed to hack our brains and trigger the exact specific response that they want from us. Once you are aware of how much human psychology goes into advertising, you will never look at an add the same way again."

Humans

"Lead in gasoline may very-well have decreased the human IQ on a global scale while in use... https://www.utilitysmarts.com/automobile/gasoline/why-is-lead-in-gasoline/"

"There's also a theory that the spat of serial killers between ww2 and the 2000s may have been partially due to this."

BOOM

"The capability to harness nuclear explosions."

Out There

"That things we thought were stars (or fuzzy stars) a century ago are actually entire galaxies. Who knows who or what the F is out there?"

OnionTruck

"Which is exactly why I think anyone who doesn't believe in aliens is just in denial, cause there SO MUCH UNIVERSE out there that even if life came about on Earth by a total million-in-one accident that it almost certainly has happened somewhere else."

Changes

"Finding substances that can change your behavior, memories and general personality."

tentacles

"Giant squids. Suddenly the old sailor story's of krakens wrapping tentacles around a ship and pulling it into the ocean doesn't seem like fiction."

OneTyler2Many

Forever

"Lobsters are practically immortal and continue to grow as long as they don't die from disease or killed by predator."

merkitt

Tiny

"That a person can be killed by organisms so tiny that we can't even see them."

A Billion Years

"Sun is going to die. It will explode and stop providing energy after 5 billion years. We better find a new star to relocate by then. Nearest star Proxima Centauri is 4.5 light years away from Earth and with current technology we can reach the neighbouring star in 6300 years trip."

srvanika

Well that is the antithesis of comfort. Life is so fun.
