Have you thought about space?
Imagine the first time you learned about the megalodon, the giant whale shark that lived during prehistoric times. To understand something that size once existed is a feat the human brain struggles to comprehend. It's the same thing when you think about the size, and mystery, of space. The first time you learn about the space between stars is an eye-opening experience, and it only gets crazier from there.
Reddit user, u/zjaf, wanted to hear the horrifying truth when they asked:
What's the scariest space fact/mystery in your opinion?
Surrounded By The Mechanical Bed We Made
Giphy
Here's one closer to home. The Kessler Effect is the theory that a single destructive event in Low earth orbit could create a cascade where satellites break up into tiny fragments taking out other satellites, breaking up into smaller fragments and so on, until the earth is completely surrounded by a massive cloud of tiny flying death shrapnel which would make leaving this planet almost impossible.
If you look up how much space debris there is already up there and how many satellites currently orbit, plus the continued growth of the commercial space industry... I think about it a lot.
Just A Whole Lot Of Nothing
Super massive voids.
Some as big as 330 million light-years in diameter. 330 million light years of almost nothing, no stars, no galaxies, no planets.
A Little Farther Every Day
People think that the universe is expanding and more stuff is added but that's not the case.
New stuff isn't being added, the universe is just being stretched out slowly. Every minute that passes space travel becomes a fraction less likely. And in a google, the universe will have stretched so thin that there is nothing left
Lurking Out In The Inky Dark
The dark forest theory as a answer to the Fermi paradox.
If i remember correctly it's from a sf book trilogy,
https://en.wikipedia.org/wiki/The_Dark_Forest
It's the idea that we don't see signs of civilizations in space because all civilizations that revealed themselves on a astronomical level got destroyed by other malvolent aliens lurking silently.
Then you remember the voyager probes and all thoses signals we send to space!
Every Time You Think About Lightyears Your Brain Dies A Little
Lightyears.
The fact that I can't move as fast as light. Even if I could, I wouldn't live long enough to last the journey.
Such a tease.
Galactic Bumper Cars
The fact that the galaxy closest to ours, Andromeda, is heading our direction at a speed of about 200 miles per second, and one day the two will collide, possibly launching our solar system into deep space in the process.
Ha-Ha-HaYeahbuwhat?

BLACK HOLES
To put it in perspective it's exactly the kind of thing we'll never know about.
Because if there was one heading straight toward us, we would be so uneqivacoly f-cked the absolute best-case scenario is to just engage in global information suppression and murder anyone who finds out so that the rest of the population don't descend into whatever chaos realizing we're all going to die and there's nothing that can be done to stop it, would occur.
I think the only thing we could do is literally move the planet and/or solar system out of it's way.
That's the most realistic thing we could do.

A... thing... that affects the motion of galaxies for hundreds of millions of light years.
It Could Be Anything. It Could Even Be A Boat.
The Bootes void.
An area of space where there should be 50,000 or so galaxies (compared to other areas of the same size) but there's only about 60. Could just be empty space for some unknown reason, or it could be an ever expanding intergalactic empire using Dyson spheres. Also I think it appears to be growing but that could just be galaxies moving away from the void
Edit: so it turns out it's 2000 and obviously it's not gonna be aliens but the theory is still cool af
We Might Already Be Gone

Vacuum decay is one of the scariest concepts to me. We don't know if it exists, and we won't know until it's too late.
On the other hand, you'll never know. You'll just blink out of existence one day. So nothing to worry about.
Perfection Or Coincidence?
Total Solar Eclipse and its existence.
Explanation:
It sheer coincidence and perfect match.
Coincidence: The size of Moon and Sun as perceived from Earth is exactly the same. So then moon gets in between Earth and Sun, it almost completely covers the Sun. There is no scientific reason that they should appear to be of the same size from here. Infact, we have not found this phenomenon anywhere else till now. Fun Fact, in next 600 million years, the moon would have drifted so far apart that we will not be able to see any total solar eclipse after that. We are lucky to have borne in that small window of time to witness it.
Perfect: The size match between Sun and Moon is amazingly perfect. It is neither too much, nor too little. Infact, the match is so perfect, that astronomers used total solar eclipse to watch and study Sun's Corona, the sun's atmosphere (consisting of mostly hot ionised gases called plasma) which remained uncovered by the Moon's shadow.
The amazing level of coincidence and perfect match makes me wonder 'at times' of an intelligent design.
What Can Stop A Nebula?
The coldest thing to ever exist is half a kelvin degrees. Thats near zero. Half a kelvin is almost -274.15 degrees C which is absolute 0. Mothing can move and nothing can happen.
This thing that is almost [impossible] to move? A F-CKING NEBULA. I find it [terrifying] that a nebula formed from a star (fact check me if I'm wrong of course, I'm not an encyclopedia) which is MILLIONS of degrees, could be cooled down to almost absolute zero.
Let's Do Some Math! For Fun!
Its vastness.
If you become a 100 years old, that's 100*365*24*5 = 4380000 or 4.4 million kilometers that you could walk, if you walked 5 km/h, every day, all day.
Now here's the kicker:
Mars is 141 million kilometers away from us. We can barely walk 3.1% of the way.
If we ran 25km/h, every day all day, we would be 15.5% of the way.
We wouldn't even be able to go to the nearest f-cking planet.
Even walking to the moon would take us 8.77 years. Running? Just a measly 1.75 years
Even taking the car with 100km/h (62 miles/h) would take us at least 160 days to the moon, assuming no breaks, of course.
Think Billiards, But In Space
Rogue planets: Planets that do not follow any given orbit.
They may have been in an orbit at one time, but now they refuse to "play by the rules."
They were most likely knocked out of their orbit by another body, and now they are set on doing the same.
Back2BachHa-Ha-Ha-HaThat Was So Close...
Astronomer here! There are a lot of things posted here that are not really likely to happen any time soon or affect your life on Earth much. So, if you want something to worry about, may I introduce you to the Carrington Event of 1859. Basically Carrington was a scientist who noticed a flash from a huge cluster of sunspots, which was the biggest coronal mass ejection from the sun ever recorded (aka a ton of material ejected from the sun at high speeds). It hit Earth within a day- aurora were seen as far south as Hawaii, wires on telephone poles burst into flame, and telegraph operators even reported contacting each other when not connected.
If a similar event were to strike Earth today, it would cause billions of dollars in damage, because blown transformers are super hard to replace and a lot of satellites wouldn't be able to handle it (and it goes without saying you'd have a serious radio blackout for a bit until it ended on a ton of essential frequencies).
The crazy thing about the Carrington event though is we really have no idea how often such events happen. But we do know that in 2012 there was a Carrington-level solar flare that barely missed Earth...
We're Just So, So, So Small...
This visual that either shows how slow light speed is or how vast space is, depending on which way you look at it.
I've seen videos showing the scale of the universe before, but this one really hit home for some reason. The speed of light, the fastest speed possible, looks painfully slow when you look at it in the context of even a fraction of our solar system. We're stuck here, aren't we?
SERIOUSLY. Bigger Than We Could Possibly Imagine
Giphy
The sheer distance between things. It's scary and somewhat depressing.
It often blows my mind when I look up at 2 stars that look super close together and realise they are probably just as far apart from each other as they are to us.
When you look up at the night sky (in any urban areas or those with sufficient light pollution...) The stars you see (think the constellations and other bright stars) with the exception of the super bright blue A-Type stars, they are usually no further than 500 light years away.
The biggest, brightest (non A-Type) star in our typical (night) sky is also one of the biggest discovered in our galaxy: Betelgeuse. At 541 light years from earth is it the furthest star in the Orion Constellation.
Those A-types I mentioned, can be seen to about 2000 light years away.
Our galaxy is between 70,000 (main core of stars and the limbs) and 150,000 (the outliers before you get to the clouds (other galactic remnants from old collisions) ) light years across.
Only seeing those stars that are 500 light years in radius gives us less than 1% of our galaxy to light up our night.

For many childhood memories are overrun by living nightmares.
Yes, children are resilient, but that doesn't mean that the things we see as babes don't follow us forever.
The horrors of the world are no stranger to the young.
Redditor -2sweetcaramel- wanted to see who was willing to share about the worst things we've seen as kids, so they asked:
"What’s the creepiest thing you saw as a kid?"
Serious Danger
"Me and my best friend would explore the drainage tunnels under the Vegas area where we grew up. These were miles long and it was always really cool down there so it was a good way to escape the heat of our scorching hot summers. We went into this one that goes under the Fiesta casino and found a camp with a bunch of homeless people."
"Mind you we are like 11 years old lol. And we just kept going like it was nothing. It wasn’t scary then but when I look back at it we could have been in some serious danger. Our parents had no idea we did this or where we were and we had no cellphones. We could have been kidnapped and never have been found."

Waiting for Food
"I was at a portillos once when I was 12 and I was waiting with my little brother at a booth while my parents got our food. This guy was standing with his tray kind of watching me then after a couple of minutes he started to walk over really fast not breaking eye contact with me."
"He was 2 feet from the table and my dad came out of nowhere and scared the s**t out of him. He looked so surprised and just said he wanted to see if I’d get scared or not. He left his tray full of food near the door and left. My folks reported him but we never went to that location again since we found a better one closer to home."

Captain Hobo to the Rescue
"When I was a pretty young teen, my friends and I were horsing around in San Francisco and started hanging out to smoke with some homeless guys. Another homeless dude came up and began aggressively trying to shake us down for anything (money, smokes, a ride, drugs- all of it) and wouldn’t take no for an answer."
"We got in over our heads and could tell this guy was now riling the other 2 guys up and they were acting like they wanted to jump us. Some grandfather-looking old homeless man appeared out of nowhere and yelled at us to get the f**k out of here- nice kids like us don’t belong down here at this hour!!"
"Captain Hobo saved our lives that night. My parents sincerely thought we were at a mall all day lol."

"We were a group of kids who went to swim in a local lake. And there was a dead body on the beach with their hands raised and their legs bent unnaturally that local police just took out of the same lake. I've never put my foot in these waters again."

Be Clever
"I was walking to school and I was about 5 or 6 years old and some guy pulled up beside me in his car and asked if I would get in. He also offered me sweets to do so. I said no. The creepy bit was when he calmly said ‘clever boy’ to me, then drove off. I’ve never even told my parents or anyone else about this as it would most likely freak them out."

Bad Jokes
"Dad's side of the family pranked me by burying a fake body on our back property and had me dig it up to find valuables. Was only allowed to use a lantern for light. They stuffed old clothes with chicken bones. Sheetrock mud where the head was... Random fake jewelry as the treasures... I was like maybe 10 or 11.. I remember digging up the boot first and started gagging because it became real at that point."

Siblings can really be a bunch of creepers.
No one should talk to others in the dark though.
Not all pet owners have the same relationship with their pets.
While anyone who decides to become a pet owner, or pet parent as some say, love their pets equally, some never ever let them leave their side.
Taking their pet with them to work, running errands, even on vacations.
Many pet parents even allow their pets to share their bed with them when going to sleep.
For others though, this is where a line is finally drawn.
Redditor Piggythelavasurfer was curious to hear whether pet owners allowed their pets to share their bed with them, as well as the reasons why they do/don't, leading them to ask:
"Do you let your pet sleep in your bed? Why/why not?"
The Tiny Issue Of Water...
"Absolutely not."
"I have fish."- Senior-Meal3649
Everyone Gets Lonely Eventually...
"I adopted an eleven year old cat the day before Halloween."
"She has mostly lived in my closet since I got her, and she hasn’t been too interested in coming out."
"Last night, she came out of my closet and jumped up on my bed, and crawled under my covers and curled up by my feet to sleep."
"I was so happy!"- YellowBeastJeep
The Comforting Reminder That You're Not Alone...

Who Needs An Alarm Clock?
"I let my two cats sleep with me."
"They're so full of love and just want cuddles all the time."
"And so do I."
"We've all developed a lil routine."
"Get to bed, oldest sleeps on my feet to keep them warm, youngest lies in my arm while I lie on my side (she the little spoon), then when I snooze my alarm for work in the morning the youngest paws at my face and meeps loudly to wake me up."- GhostofaFlea_
Whose Bed Is It Anyway?
"Yes."
"They're also kind enough to let me squeeze into whatever space they've left for me."
"Although I do get a few dirty looks off them."- Therealkaylor
"I found this tiny kitten screaming her head off under a car."
"Would not come out."
"Got some food and some water in dishes."
"I stood by the tire so she couldn't see my feet."
"She got curious about the food and water and started gobbling it down."
"I thought she would bolt when I squatted down."
"She was too busy eating."
"I grabbed her by the nape of the neck and all four legs went straight out and she tried to scratch me to death."
"I got her in the door and tossed her toward the couch."
"She ricocheted off the couch as if she was a ping pong off a table and I lost sight of her."
"I put out food and water and a sandbox and did not see that kitten for three days."
"On the third day, I came home and she was on my bed pillow."
"I thought she would bolt when I came near, but she didn't."
"I wanted to sleep so I tried to scoot her little butt off my pillow."
"She would not go."
"I put my head down to sleep and that is the way it was from then on."
"She ran the roost."- Logical_Cherry_7588

Is That My Hair On That Pillow?
"My dog is perfect."
"She comes up, cuddles til we start to fall asleep, then gets down to sleep on her bed so she doesn't get too hot."
"Jumps back up in the early morning for wake up cuddles."
"The hair everywhere is the only downside but she is so cozy, what can you do."- HoodieWinchester
It is easy to understand how some people are able to fall asleep more easily knowing their friend and protector is there, in bed, with them.
Though we can't blame others who don't want to run the risk of being scratched or bitten in the middle of the night either...
