‘What Is A Scientific Fact That Absolutely Blows Your Mind?’: People Share 35 Incredible Facts About Our World
The world of science has been capturing our imagination for ages. Especially in the current times, when a part of the public is skeptical about the things scientists tell us. While causing a divide, it reminds us just how much (and little) humans know about the world around us, whether it’s Earth, space, living beings and entities that live in them, or our own bodies.
So today we are diving into a mind-blowing science class where facts sound too crazy to be true. And thanks to Redditor analyzeTimes, who asked “What is a scientific fact that absolutely blows your mind?” on the Ask Reddit community, we have a whole lot to uncover. From a Voyager that has been traveling >30,000 mph for 43 years and is only 20 light hours away to our brains simultaneously creating stories and being genuinely shocked by plot twists as we dream, these are some of the best ones to mess with our brains.
Scroll down, upvote your favorites, and share a scientific fact you find hard to wrap your head around in the comments below!

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.
I think it also happens when awake: "What if this thing happened/I did something?" "How and why are you thinking about this far fetched thing?"
I spent some time with Gene Cernan, the Apollo 17 astronaut who was the last guy to walk on the Moon. He told me two things that I couldn’t stop telling people:
1. the Earth is round in space like a ball, not flat looking like the Moon is to us. He said while looking up from the lunar surface, the Earth just hung there, like a grapefruit that he could almost grab if he just jumped high enough. Could see the weather change too.
2. because of the smaller size of the Moon, not only is it’s curve very visible, the apparent horizon is also much closer so he said there were moments where if he ran too fast or jumped too high he felt like he was going to fall off.
Trees can communicate and cooperate using a network of underground mycelium. They can store excess energy in it for later use, can trade different nutrients with neighbors so their needs are met, take care of their young when they're unwell, and even warn others of a spreading disease or parasite.
And then bipedal macrofauna come by and cut vast holes in that network, dump chemicals on it, or set fire to it.
The time period in which dinosaurs lived is so vast, there were dinosaur fossils when dinosaurs were still alive.
There are human fossils while humans still exist, and we haven't been here anywhere near as long as the dinosaurs were. Also, there's more time between Allosaurus and T. rex than between T. rex and humans.
Whales will grow up singing a specific song based on where they were born, but they’ll learn verses of other songs from whales they encounter throughout their lives!
Hippos sweat sunscreen. They produce "sweat" made of one red and one orange pigment. The red pigment contains an antibiotic, while the orange absorbs UV rays.
Some forms of anaesthesia don’t numb you to pain- they make you forget that you felt it.
Retrograde amnesia are the words you're looking for. It's fairly common to use an agent like Ketamine to help relax someone, dull the senses, pop a dislocated shoulder back into place, and then let them wake back up. In the ER/Trauma world we would call it moderate sedation and it's fairly routine.
I was given Ketamine in the ER for a severe asthma attack. I stayed awake through a weird and intense mini-trip. Totally numb though.

Too true. Ex OR nurse here. Surgeons need a specific environment to work. They want the patients to not move (paralytic), not feel(numbing agent), and not remember anything. The combination is anesthesia. Throughout the surgery anesthesiologists (or anaesthetists in some countries) monitor vitals and other signs of patient status to determine the effectiveness of the drugs for maintaining the three and titrate the drugs based on the length of surgery and other factors. What sucks is when the body metabolizes something outside of the norm and you get unusual results. Red heads apparently require way more drugs for whatever reason. Anesthesia is so fascinating and I'm SO glad that was never my responsibility.
Redheads are so wild the brain laughs off standard attempts at any kind of restriction.

There is a true story of an ill man known as George who out of despair shot himself in the head in an attempted suicide, only to cure himself. The .22-caliber 'surgeon' eliminated only the section of the brain responsible for his OCD. He became a straight-A student. In many medical scientific journals in articles related to brain function, there are references to the case
It’s conscious sedation. Used commonly and successfully in endoscopy all the time. NOT used for major or open surgical procedures.
Every time I'm on a conscious sedative, I resist it. Every time, I warn them that I'll resist. Every time, I get some version of "it'll be fine, this is the good stuff". Every time, the doctor has to fight me to do the job and barely gets the basics. Found out recently that I also resist general anesthesia but not as successfully.

They used to give this to women during childbirth - after the birth the women thought they'd been asleep for the whole thing, because they couldn't remember it
Yes, twilight sleep. From most accounts it was horrific. Women gave birth disoriented and restrained. My grandmother talked about waking up at the hospital covered in bruises and not knowing if her baby was even alive.

Morphine. Last year I went to hospital for emergency appendectomy. I was talking to the doc as he was getting me ready for surgery. I told him Hey doc! I figured out how morphine works! He says oh yeah? I said yea! I said Morphine doesn't make the pain go away. It makes you just not give a s**t about it anymore. He laughed so hard, and said I was right. And then they knocked me out and took out my exploded appendix.
I remember giving a woman some pain meds after surgery, then asking her if she was still having pain. She answered, "I think I am, but I don't care."
after many surgeries, both major and minor, i don't care...as long as i don't feel or remember. the post op pain is enough
And there are anesthetists and anesthesiologists. And neither are spellable.
Anesthetists and anaesthesiologists more like :-) (Anesthetist more American term, anaesthesiologist more British)

I learned, from extreme kidney stones, that some 'pain relief' just moves you aside from the pain. You are still in pain, but you don't have a psycho-emotional response to it. Very weird.
If I'm understanding correctly. Some of them work similar to smoking weed. Right?

For major surgery, anesthesia is a cocktail of drugs. One to paralyze, one to induce unconsciousness and one to induce amnesia so you can’t remember what happened.
That's how the sedative for a colonoscopy works. I have this image of doctors and nurses cackling as I scream, then switching to their compassionate, somber mode when I wake up.
That's why they call it "milk of amnesia". Often used for setting broken bones and dislocations.
Best drug I ever had post-op was Fentanyl. Absolutely loved it and I can see why people chase that particular dragon!
Often they refer to 'sedation' for minor procedures where you are not 'out' but will not remember anything. I have my nerve roots treated with laser & the surgeon needs me awake to indicate to him he has hit the right spot in my back. Once they overdid it & I fell asleep so everyone had to wait until I woke up
Well, once it wears off the pain jogs your memory real good. I’ve had surgery twice, ten years apart, and both times I came home from the hospital feeling OK, but within 24 hours the pain from the incisions came roaring back with a f*****g vengeance, and I felt every single bit of it. I have a pretty high tolerance for pain, but I’m not totally impervious to it. That s**t HURT. Since I don’t want to mess with opioids, all I had was ibuprofen to help me get through that initial surge of excruciating pain. It’s not as good as the stronger stuff, but I got through it just fine. Both times. Without becoming dependent.
Actually it is almost impossible to become dependent on an APPROPRIATE dose of opioids i.e. one titrated for your actual level of pain. People become addicted because they take a dose too large for the damage that is there, or because they take a dose when there is no actual pain.

My doctor's told me that when I went in for hysterectomy. Which is why they also did a nerve block. Woke up from surgery with no pain and was pain free for about 12 hours after as well.
It's true. Watch a certain MrBallen video on YouTube about someone who wasn't anaesthetised properly before an operation. He suddenly started reliving it at home weeks after the operation. His wife though she was going insane.
Maybe it is because the doctor/surgeon needs us to feel pain, to do their job correctly and find the right place. But I wonder how they know, if you are numb
I've had that kind, it's very odd. I used to get a spinal ablation done every six months and they give you this twilight type sedation. Then a local in the area. They have to keep you awake because it's your spine. For those that don't know.... ablation is where they take a very long rod and a spring pops out the end, it heats up to something like 150 degrees (maybe more) and they burn the nerves that are causing you issues. It's uncomfortable. But by the time the anesthesia wears off, you don't remember any of the pain. It's un real.
This is not technically true. Anesthesia comprises a combination of analgesia (not being able to feel pain), amnesia (not being able to remember) and paralytic (not being able to move). Anesthesiologists don't administer the "drug that makes you forget" all on its own. They titrate the three.
Morphine does this for me. It doesn't stop the pain, just kinda moves it waaaaay over there for a while. And made my triceps spasm when they put it in my iv.
I heard a story of a man who went into surgery and they gave a paralysing drug and forgot the anaesthesia so the man was fully awake during the first 10 minutes of the procedure, until a nurse realised this called the anaesthesiologist to put him under narcosis. When the man woke up after the surgery he did not remember anything but developed some kind of craziness several days after. He did not know what was happening to him because he did not remember, but his family went to the hospital and did nome investigation and figured out what had happened with him. The man a couple of months later took his own life. Sad story!
You can ask and tell them not to use that drug. I've had a lot of operation, I've always talked with the anastioligist .
IV cannua put in, administer IV propofol (the drug that killed Michael Jackson. Propofol can only keep you asleep if it is continuously administered). Most of the time, after the Propofol, anaesthetic gases are administered. A pain relief medication will be administered IV. Local anaesthetic will be administered to the incision area because of the original Bored Panda fact. Local will numb that area. IV and gases will keep you asleep
Yeah well, the one used on me when I had dental surgery to remove fused wisdom teeth failed horribly and I remember every last second of that nightmare and it's the reason I avoid dentists like my sanity depends on it.
My daughter (6) told me she didn't like it when they put the thing down her nose, it hurt. It was a tube to help her breathe, she should have already been out....
Versed. It's great. You are awake and can answer questions but remember nothing. It reveals that pain is much more than the ouch. It's anticipation and memory as well.
That's why versed is such an awful execution drug. It doesn't knock you out.
I was given diluted propofol during a surgery once to keep me relaxed. Surgeon didn't want to put me fully under so was given an epidural to numb me instead. Had pethidine a couple times as well after. Doesn't do anything for pain, it just makes you high.
Also, you can wake up during a surgery and not be able to move. But you can feel EVERYTHING. 😈
Uh... Uh... Hey can I have this shît on standby after my too-regular nightmares?
Yeah but they'll still give you a topical anesthetic, if that's what you want. Even just to calm anxious people.

The knowledge that the atoms of our bodies contain elements only forged in the center of stars, and that such stars upon death blow the elements via supernova across the universe and into our very existence. We are made of star dust.
Scientists know virtually nothing about dark matter and dark energy, which make up about 95% of the universe. So, we basically know nothing about the stuff that makes up 95% of our reality! Talking about being kept in the dark!
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).
Quite an upbeat description of hemispherectomy. My 10 yo daughter suffers from a rare and severe form of epilepsy. There is no cure and the prognosis is that her condition will gradually worsen. When her quality of life becomes catastrophic enough, the only thing left is to have a hemispherectomy. In almost all cases the procedure will lead to severy cognitive disablility and partial paralysis.
Caterpillars basically dissolve into liquid in the cocoon. The only thing left are the so called ‘imaginal discs’, groups of cells that contain all the information and the mechanism to turn that soup into the various body parts of a butterfly (the same applies for other insects).
If the entirety of the Earth’s history were compressed down to a single day, humans of any sort wouldn’t appear until the last second before midnight.
That there is a species of jellyfish called Turritopsis dohrnii, that can become young again when damaged or stressed. So they become young again. So they are immortal. Just an addition, the tardigrades. They can survive the vacuum of space.
A million seconds is 12 days. A billion seconds is 31 years. A trillion seconds is 31,688 years.
The size of animals still blows my mind. You can read about how a manta ray is 23 feet long and 3 tons but it doesn’t really hit you until you realize that’s heavier than most cars.
Humans have hunted most of the megafauna into extinction. We have hard time coexisting with big animals.
When you lose weight it leaves on your breath.
So when people lose 100 lbs/ 50 kg, they have exhaled that much carbon.
An object has every color except the one you think it has, because its the only color that doesn't get absorbed.
Great. Now I'm suspiciously staring at everything on my desk and telling those inanimate objects, "Reveal your true forms, you chameleons!"
If some sort of super-advanced alien species on a planet 80 million light years away from Earth built a high-tech telescope that let them see objects on the Earth's surface, they would be seeing dinosaurs right now.
And also if there were aliens 5 billion light years away and they detected our signals we would be long gone by then. Those aliens would arrive at a scorched empty planet without any life
Sharks are older than trees, also, trees almost destroyed all land life on earth as there use to be nothing that could decompose them, so dead trees covered the ground and killed all other vegetation. Only once fungus evolved did trees start decomposing.
The trees that couldn't be decomposed turned into coal. No new coal has formed since the fungus evolved to break down the dead trees
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.
Voyager 1 has been traveling >30,000 mph for 43 years and it's only 20 light hours away.
The Cathedral Effect. If you work in a room with low ceilings, you will stay a bit more focused and be better at detailed, analytical work. If in a room with high ceilings, you will be more open and creative.
This can be simulated by wearing a brimmed hat if you’d want to hammer away at say data entry or data analysis.
There are some Ice Age animals that are so perfectly preserved in permafrost that scientists have been able to find them still with all their soft tissue, hair, and organs. They even found a couple mammoths that still had liquid blood in them and I remember one scientist even tasting the mammoth meat.
A recently discovered vine can mimic nearby artificial plants, modifying the size, shape and colour of its leaves to match them. The only plausible explanation is that plants can see.
Exponential power.
Fold a “big sheet” of paper - that is 0.1 mm thick - 50 times and the height of stack is over 20 times the distance earth to moon. Thank you.
You can theoretically do this but you cant fold a piece of paper mroe than 7 times. Fun fact: if you were to fold a piece of papper 300 times you will end up with a book that has more pages that atoms in the observable universe
Slime molds don’t have brains or nervous systems but some how retain information and use it to make decisions. Even more crazy is that they can fuse with another individual and share the information.
In fact, they are so intelligent that they can quickly get through mazes. They have a sort of awareness that doesn’t allow them to get stuck at dead-ends.
Both the absolute hottest and absolute coldest temperatures ever recorded in the known universe were achieved here on Earth.
The hottest temperature ever physically recorded in the known universe was when scientists at CERN used the Large Hadron Collider to collide lead ions. This produced a temperature flash of 5.5 trillion degrees celsius.
That’s 5,500,000,000,000°C. Convert to Fahrenheit, and you get this:
(5.5e+12°C × 9/5) + 32 = 9.9e+12°F
For the record, the current temperature at the core of our sun is around 15 million degrees celsius. 15,000,000°C. That’s 350,000x less intense than the flash produced by the lead ion particle collisions. That temperature, even if minuscule and fleeting in size and duration, was actually created here on Earth, in a lab. Let that sink in.
The coldest temperature ever recorded in the known universe was achieved relatively recently by a group of German researchers who achieved a nearly incomprehensible feat of 38 trillionths of a degree above -273.15°C, or more commonly known as Absolute 0° Kelvin. They did this by dropping magnetized gas down a nearly 400 foot tower in order to study a 5th state of matter; Bose-Einstein Condensate. For the record, weird s**t starts to happen near absolute 0°K. Example? Light turns into a liquid you can pour into a glass.
The coldest place we have recorded data from within our observable universe is the Boomerang Nebula, hovering nearly an entire degree (kelvin) above absolute zero. Still unfathomably cold.
So while we are still essentially infinity away from achieving Planck Temperature (the staggeringly high temperature of beyond decillions of degrees celsius in which conventional physics breaks down and we enter a whole new realm of theoretics) we are extremely, extremely close to achieving absolute 0°K here on Earth.
However due to quantum mechanics we cant go to 0k since when measuring a particle we cant know how fast it is and where it is at the same time. If we get an atom to 0k then we would know how fast it was going= 0 and where it was which isnt allowed in this universe
You can fit all the planets (Pluto included) between the Earth & Moon.
Planets are actually really far from each other! Here is what they look like to-scale: https://bit.ly/3BGl5Hr
Giraffe necks are actually too short to reach the ground, so they have to splay their legs in order to drink water.
The astronauts on the ISS aren't floating around because of lack of gravity, far from it. They are in constant free fall, falling over the horizon of earth. Being pulled by gravity towards the earth.
Cleopatra lived closer to the moon landing than the building of the great pyramids.
The oldest known beer jug is over 5400 years old. Archeologists discovered ceramic vessels from 3400 B.C. still sticky with beer residue. 1800 B.C.’s “Hymn to Ninkasi" is an ode to the Sumerian beer goddess. No warrior/beer helmets have been unearthed yet.
If 2 pieces of the same type of metal touch in space, they will bond and be permanently stuck together. Space welding (cold welding).
If all the DNA in the average person was stretched out in a single line, it could reach from Earth to the Sun and back 248 times.
With the help of quantum tunneling, there is a 1 in 5.2^61 chance that the molecules in your hand and table would miss each other when slamming it, making your hand go through the table.
1:520,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (hope I did the zeros right)

I've got an uninteresting scientific fact; jays (that used to be quite uncommon where I live) are excellent sound mimics, which was proven to me by the fact that me and a bunch of neighbours this morning spent an hour looking for the dying cat we could all hear screaming that turned out to be a mf jay sitting in the top of a tree >:(
me & a buddy ran through stickers and briars through a field once to 'save' a woman screaming "help!" - it was peacocks.

In the cold death version of the universe where everything just gets further and further apart and energy ebbs away, this entire 'bright' phase with stars and galaxies etc is so brief as to be almost unmeasurable. "Forever and ever" is actually a nasty curse to wish on someone.

Aluminum is an excellent heat sink, so putting a piece of frozen meat on a heavy aluminum cookie sheet will cause it to defrost much faster than a piece of meat lying on your counter. It acts like its sucking out the cold, but it's really conducting the heat of the air into the vacant energy of the meat
I wondered how that "magic defrosting tray" worked. thanks.
