Science is fun!
You might have had a bad time in your early schooling days, learning how the mitochondria was the powerhouse of the cell. While that's certainly important for certain biologists to know, we want the spicy stuff. The facts and info that makes our hair stand on end and our brain cells ignite with the possibilities of the universe.
Stuff like this.
Reddit user, analyzeTimes, wanted to learn some fun stuff when they asked:
"What is a scientific fact that absolutely blows your mind?"
Let's start with some crazy numbers! Everyone likes numbers, especially when those numbers are all about making us lack any real understanding of probability and the passing of time.
Time Is Longer Than We Think
"The time period in which dinosaurs lived is so vast, there were dinosaur fossils when dinosaurs were still alive."
daric
"Yes, Tyrannosaurus Rex is closer to the iPad in timeline than it is to the Stegosaurus, by tens of millions of years."
"We are so used to seeing dinosaurs portrayed in a single timeline (children’s books, museums) that we don’t understand the vastness of time they were around."

Beetles, Beetles, Everywhere
"If you put 1 of every animal in a bag and then pick one out you have a 1/5 chance in picking a beetle"
ItsStillNagy
"And 1/2 chance of picking an insect of any kind."
"To put it another way: half of all animal species are insects, and 40% of those are beetles."
“If one could conclude as to the nature of the Creator from a study of creation it would appear that God has an inordinate fondness for stars and beetles.”
– evolutionary biologist J.B.S. Haldane

It's The Greatest Game Of All Time
"There are this many atoms in the universe: There are between 10^78 to 10^82atoms"
tastey_orphans
"there are even more possible variations of chess games than there are atoms in the observable universe. This is the Shannon Number and represents all of the possible move variations in the game of chess. It is estimated there are between 10111 and 10123 positions. This includes illegal positions. The number not including illegal positions would still be stupid huge as only moves that put your king in check are illegal"

The brain is the most fascinating thing, and we're all just walking around with one inside of our heads. Ever wondered what it was capable of doing?
Even Your Dreams Need To Be Spiced Up
"When you dream, one portion of your brain creates the story, while another part witnesses the events and is really shocked by the plot twists."
Longjumping_Owl9929
"It gets even weirder. There's 2 kinds of dreaming, the watching kind (non-REM) and the doing kind (REM). Each night, you go through 3-4 of these non-REM and REM sleep cycles. The non-REM sleep is the deeper sleep and the REM is the lighter sleep."
"So in the watching kind, it's like you're watching a movie, you're passively observing a character your subconscious created going through a situation, for example, you watch a character you created subconsciously go through their first day of high school. After observing it and drawing some conclusions, or gaining some insight, you then go into REM sleep and now you're the one going through their first day at high school. You make the decisions, you feel the emotional responses to what's going on, and your body will have physical reactions like sweating from fear, increase heart rate from excitement, dopamine release from something good happening, etc. So it's like watching a training movie and then getting a chance to do it in a practice dream scenario."

Ever Feel Like You're Talking To Yourself?
"I recently read about the Split-Brain experiments. There is a procedure for severe epilepsy that involves cutting the connecting nerves of the two brain hemispheres, resulting in the two hemispheres being unable to communicate with each other. The experiment shows that both halves can answer questions independently of each other, have seperate opinions/preferences, form memories independantly. Basically suggesting that there are two minds in the brain. That just blows my mind(s)."

People Afraid Of Spiders Need Not Try
"There are actually blood vessels obstructing light from reaching certain areas in your eye, effectively creating a shadow. Your brain filters this out and essentially fills in the gaps so you don’t actually see this spiderweb-like network of black lines. However, you can visualise them by shining a light at a diagonal into your eye (not directly!) and gently wiggling it about. This means your brain doesn’t have enough time to filter it out and you see this spiderweb like network of blood vessels!"
"Technical instructions to clarify the actions involved. I find it easier to see this effect in a dark environment, so the contrast of the black shadow against the light is higher. You want to be staring straight ahead and shining the light into your pupil at a 45 degree angle from the side directed at your nose at about 10-20 cm away from them. Phone light will do great and have it on the dimmest setting if possible. Then wiggle the light in gentle 1 cm movements side to side. Keep this up for about a second at least and you should see them. Hope this clears it up a bit!"

"Hey, We Should Be Keeping All This Blood In Our Body, Right?" - Your Body
"Blood is able to turn from liquid to a gel in order to stop bleeding. Basically, when God created us humans, he made our cells (and our bodies themselves) smarter than us. Now obviously it sounds like basic knowledge for blood to clot and stop bleeding. It may sound simple and basic for tissue to do such a thing, but even the most basic things our bodies do can impress us."

It's another ordinary day in America.
So of course that means we've already had a mass shooting or two before brunch.
And aside from the mass shootings, the number of single gunshot wounds or deaths is too high to count.
So let's discuss the aftermath.
Let's hear from the people who have faced the barrel of a loaded gun, or were just a casualty going about their day.
What happens after the bullet lands?
***CAUTION - SENSITIVE MATERIAL AHEAD - TRIGGER WARNING***
Redditor notaninterestingacc wanted to hear from the people who have lived the nightmare. They asked:
"Gunshot survivors of Reddit - What does it feel like to get shot?"
Guns are not a joke. Please educate yourself before you purchase.
Then the pin hit...
"I took a 7.62 to the stomach in Afghanistan. Felt like somebody had smacked with like, I dunno, a flyswatter or something. A short sharp smack. Didn’t feel much until I tried to come out of cover and I just... couldn’t. Couldn’t make my body listen to me. Then the pain hit. I’d put it at like, I dunno, an 11/10. Bullet blew off half my liver."
eyeCinfinitee
Thank you EMS...
"Chest, .357 magnum, through sternum, lung, ricochet off of rib, through scapula. Still have half under my shouldblade. Felt like I was stabbed in the chest with a hot fire poker mounted to the bottom of someone's foot when they drop kicked me. Was not expected to survive (severe blood loss), of course. Very good EMS team kept the liquids where they were supposed to and great doctors and nurses kept me going."
mndyerf**kinbusiness
Knocked Back
"I didn't really feel either of mine until about 10 minutes later. Took a grazing shot off my left arm and one in the right hip that went out my back thankfully missing my kidney. The arm felt like a bee sting the hip knocked me back a step the adrenalin at the time masked the pain."
richwith9
The Masked Men
"I was shot during a home robbery. I’m probably one of The luckiest people alive. The bullet no joke scratched my cheek and then went through the top of my ear and also a bullet grazed my wrist and opened it up. I didn’t feel anything but just liquid running down my face and my wrist was burning."
"Scariest night of my life and RIP Christian. Miss you so much buddy. Here is proof. We... https://www.chron.com/neighborhood/katy/crime-courts/article/Man-charged-in-attempted-burglary-apartment-6236325.php Authorities said Burke and Brandon Fries, 21, fought the suspects for their guns, which were fired during the struggle."
"The two masked men fled, and investigators initially did not have any information about which direction they went or whether they escaped from the scene by car. Both Burke and Fries had been shot and were transported to Hermann Memorial Hospital in Katy. Burke was pronounced dead upon arrival at the emergency room, less than four miles away.”
Brandonfries28
Like a Rock
"I got shot in the ankle when I was 10. Honestly I thought a rock hit me. Just a slight stinging feeling. Didn't really hurt, I even kept running with my bike. Later at the hospital was a different story. The doctor tried to remove the bullet without putting me under."
"He said the pain medicine would make me forget everything. He gave up after a few minutes of hell. And, whatever he gave me didn't work as described, but it did oddly make everyone look purple from what I remember. So maybe it half worked? lol."
adamchilders
People really? How in the world do y'all get firearms?
Fleshed Off...
"Right thigh, 9mm, grazing shot across the front of the leg about 4 inches above the knee. It plowed a channel of skin and some flesh off the front. It felt searing hot like someone had laid a hot piece of metal on my leg for a second. Then, the pain went away for a while until the adrenaline wore off. It honestly hurt worse 6 hours later than it did when it happened."
morgen_benner
A slight pinch...
"I was randomly shot while walking down the street with my girlfriend in 2013. I didn't fall to the ground or anything like that. Walked into a store and told them to call the cops. It didn't hurt too bad at first. A slight pinch. The heat builds up and the pain comes in. Some throbbing as the blood pumps out. I was extremely lucky as the bullet lodged between my lower right ribs in the back just above my kidney."
"The aftermath was a really achey back. What I remember most was how everyone around me except for my girlfriend just walked around us like nothing happened. I was suffering and potentially dying and everyone just ignored it. 'Not my problem' I suppose. I lost a lot of faith in people that day."
SoggyPastaPants
Not the Head
"I accidentally discharged my 9 and I was hit in the head. While it was going on I honestly did not feel any pain but everything slowed way down. Healing and recooperating was the hardest. My mouth and jaw was wired shut for several months. Had to have complete facial reconstruction surgery."
"Had to take a piece of bone from my skull and graph it to my nose just so I could have a nose. I also had to have a feeding tube for almost a whole year. I've recovered fully and I'm very lucky. I remember mostly everything. Something's from the incident I don't remember, but for the most part, I have my memories in tact."
No-Kick1632
It Burns...
"My gf was shot, not me, but she said it felt hot and like impact but not particularly painful until much later. She was in shock and went to the hospital, after hours she said it started to hurt."
DntShadowBanMeDaddy
"This was my response too. It feels incredibly hot. It's like getting hit with a bee that's on fire. It burns like hell. But then, and only later, does is f**king hurt. The part two is that you might think you understand pressure, but get shot. It doesn't just hurt, it mashes into you."
trebuchetfight
Ricochet
"A good friend of mine got hit with a ricochet from a 9mm that hit his calf, there was drive by about a block down. He was outside of the bar smoking a cig when it happened, ran inside and felt his leg burning but decided to keep drinking. He had about 3 more drinks before someone mentioned he was bleeding… went to the ER absolutely hammered and was fine after surgery."

It's never attractive to gloat.
Nor does superiority ever come off as a particularly attractive attribute.
But, consciously or not, some people speak or behave in a way that immediately suggests that they think they deserve to be treated differently, i.e better than others.
Or that they believe they simply are better than other people.
A recent Redditor was curious what sort of behavior struck other people as elitist or arrogant behavior by asking:
"What screams "I am entitled"?"
Where's the fire?
"Impatience in situations where it should be just universally understood that you need patience".- c7hu1hu.
Positions of power.
"I will have you fired!"- Vergo27.
"Generally just leaving something for someone else to deal with."- Splatty_boi_420.
Sorry, but I was here first.
"People who cut in line."- Chad_Farthousse.
"People who ignore lines and cut in the front, like their time is more important than every other person patiently queueing."- ofsquire.
No one loves a tattletale.
“I’ll call my dad and tell him what you did!”- ROAM300.
Ever heard of quid pro quo?
"When they do something to you and think it’s fine but when you do it in return and they freak out."- Silvero129.
Name your price.
"I work as a ticket seller for a ski resort."
"My favorite entitled person is the guy who, upon finding out that the kid's ski lesson was sold out, offered to pay extra if I would kick someone else's kid out so his kid could have a spot."- Floranagirl.
Perhaps one of the most obvious ways to unwittingly show off your entitlement?
By being oblivious to how entitled you are.

There's something about the woods that creeps me out. Listen here, people: I'm a city guy. The idea of getting lost out there freaks me out. No thank you. I wasn't made for that. The rest of you who like to go camping and stuff? You do you. I'll stick with my running water.
But maybe I've seen too many horror movies. After all, if I saw some creepy stuff in the woods I'd definitely run in the other direction. And so would you, right? Right?
People shared their best stories with us after Redditor shantics asked the online community,
"What have you seen in the woods that you can’t explain?"
"I stepped on what I thought was a small rock but it turned out to be weird and gelatinous. I've also seen tombstones in the woods."
his_eminence56
You just suprised it. Rocks are soft and squishy, they just tense up when you touch them! /s
"I was hiking through the remnants..."
"I was hiking through the remnants of a remote, long-abandoned town and the surrounding area. To get to as far into the woods as I was, you had to cross fallen trees over a creek three times. I had just crossed the third "bridge" and was about five miles in and something blue caught my eye just ahead of me."
"There was a man, in his sixties at least, wearing blue satin pajamas, sitting in a tree. The closer I got to him the louder he laughed; it wasn't a maniacal laugh, but it set off all the alarms in my head nevertheless. He also wasn't wearing any shoes and looked well-groomed/cleaned."
"I gave him a friendly nod as I passed and he just kept laughing. Then it stopped. I turned and he was gone. There was no branch cracking, plants rustling, nothing... He was just gone."
"Still rubs me the wrong way. The area I was in was a pretty rough hike, very secluded. Not very many people venture as deep as I was that day. No idea what was going on there."
mrwitch
“Over the Third Bridge” would be a great title for a spooky book or movie.
"Neat as a pin..."
"Fully decorated Xmas tree. Middle of summer. Neat as a pin it was, as if it had just been finished. Who ever did it came back at some point and cleaned it up, because it wasn't there next I did that trail a week or so later."
OldWomanintheWoods
This one’s not that uncommon actually. Lots of folks will decorate a tree in remembrance of someone out in the woods. Sucks when they don’t clean them up though.
"It's an interesting..."
"In Japan. A hotel was abandoned before it was ever finished being built. It only became a cement skeleton, about 5 stories high. It was left that way to eventually mold back into the forest around it."
It’s an interesting small building to explore. There are halls that are unlevel to the point of hitting your head on the ceiling (think: Willy Wonka)."
"There are stairwells that lead to nothing and one that leads to an unintentional hole in a cement wall. And on the top floor (but “inside” - as in, under the “roof”), is an old car - all smashed up - with seemingly no reason or method to have been up there."
[deleted]
This reminds me of those old abandoned amusement parks that pretty much exist to destroy me mentally.
"I once walked..."
"I once walked through the undergrowth (i.e. off the trail) with my then-girlfriend when we came across this spot where a few empty plastic bags were lying on the ground (strange because the woods are otherwise super clean), a pair of gloves and, most confusingly, the official ID card (= passport) of a young woman."
Minister_of_Joy
I would freak out and call the cops. That sounds like a murder scene.
"Many plastic bags..."
"Many plastic bags with nothing really in them but random odd things tied to trees. Sure, it could have been a homeless person but us kids att (like 12+) of us lived in those small woods behind the church every single day. We never saw anyone like that, ever. Passing through I guess, but why so many bags...still wonder."
WiseOwlBear
Do we want to know what was in them? Probably not.
"When I was a teenager..."
"When I was a teenager, I worked at a fireworks stand that was run by my friend's family. It was in a rural area: they owned a few acres of land, had the fireworks tent at the front of the property and the house towards the back, but no lights in between. My friend's mother would prepare dinner for all the workers and we'd take turns going back to the house for dinner."
"One night, I was going to the house for dinner by myself. I felt something on my arm. I thought a bug might have landed on me, but it was really dark so I couldn't see anything. I stopped walking for a second. Then I started hearing this low, raspy breathing right next to me."
"There weren't any people around me and it didn't sound anything like a bug. It was like a slow, asthmatic wheeze."
"I started getting really freaked out. I reached my hand down to my arm and felt... something larger than I expected. I furiously rubbed my hands all across my body to try and dislodge whatever this thing was, then ran as fast as I could to the house. When I finally got to the safety of the house, I could see a small red mark on my arm, but that was it."
"To this day, it's probably the most freaked out I've ever been."
[deleted]
Chills reading this! Nooo thank you!
"Several very large holes..."
"Really big holes. Several very large holes, fairly close to each other, that seem to serve no purpose. Ten feet wide, deep enough that if you jumped in you’d have to have help getting out. Was someone preparing to bury a bunch of people? Was someone punishing their kid by making them dig holes? Did they hear there was buried treasure out there?"
"We’ve never figured it out."
theyarnilama
How far apart? How neat were the holes? In a plantation or natural wood? Accessible by a small excavator?
"I once saw a huge pile of cat and dog skulls and bones about 100m from my cabin so we sold the cabin as soon as we could. It was creepy."
[deleted]
This definitely sounds like the beginning of a horror film. Did the ghosts follow you? Please report back.
"There's a small patch..."
"There's a small patch of woods where I live. You could walk across it in less than an hour. It's entirely safe and has marked trails. People somehow manage to get lost in there and I can't explain that."
ThadisJones
Did they stumble across the bounds of time and space? That might explain it. But you might be underestimating how many people lack a sense of direction.
None of this makes you want to go out into the woods, huh? Yeah, we thought so. We'll pass the next time we get an offer to go camping somewhere.

We're all not geniuses.
Everybody has varying degrees of knowledge and brain power.
And that is ok.
Though some of us are really lacking in any sense and every once and awhile people like to sugarcoat that fact when they call us out.
"Bless your heart."
That's a big one in the South. Means... "I like you, but Lord are you missing marbles."
Redditor MrMadJoker wanted to know the most creative ways to describe people who lack a few IQ points.
