The world is an amazing place with a rich history and countless phenomena that you could spend your whole life learning and still not know everything. However, we may be better off with some things, as shocking and amazing as they are, remaining a mystery to us.
Here are some interesting things about the world that you probably haven't seen before (and might wish you hadn't seen).
This Helmet Is From 490 BC
This Corinthian helmet and human skull are relics from the Battle of Marathon, which took place during the first Persian invasion of Greece in 490 BC.
The helmet survived with the warrior's skull inside it.
Outfoxed By Fatigue
Foxes are wild animals, which means they're generally skittish when approached by humans, or even when they're nosing around human habitations.
That said, every creature needs to sleep, and this futon certainly looks like a cozy and comfy option.
These Are Bees Swarming To Kill A Murder Hornet
Murder hornets, which have recently made their way to North America for the first time, apparently aren't beloved by the bees.
In this photo, they're trying to swarm and overheat this hornet to kill it.
Classic Tourists
The urge to take pictures of new and exotic sights while on vacation is universal, so it makes perfect sense that these sumo wrestlers decided to snap a few pics during a trip to London.
There's something about the juxtaposition of their traditional sumo robes and the modern cityscape of London, though, that makes things feel a bit weird.
New Album Cover
This cardboard robot is clearly homemade, with its rough lines and colorful gels haphazardly stuck in place.
While the robot itself looks a bit rough, it's utterly transformed when in silhouette form. In fact, it makes for a picture for the ages.
Penguin Egg Whites Stay Clear When Boiled
I don't know who decided to boil a penguin egg, and I don't particularly want to know.
But it's interesting that different birds' egg whites actually don't all actually turn white when cooked.
Bon Voyage
The act of scattering the ashes of a departed loved one is beautiful in its way, as we're able to give the remains new life by integrating them into the natural world.
This method of ash scattering is a bit different, as it's essentially a message in a bottle — and that bottle is the vessel through which Cara's mom will travel the world's oceans.
Snubbed, But Politely
It never hurts to invite a famous person to your wedding. In the best-case scenario, they might actually show up — and even if they don't, sometimes you'll get a fun note.
In this case, a couple invited Pope Francis to their wedding. The pontiff was evidently busy that day, but at least his people sent along a kind message.
I'd Be A Terrible Service Dog
This photo shows service dogs enduring what may be the toughest training of all: Watching an entire musical without causing a disruption.
If I was there, I'd be looking for the popcorn guy within the first ten minutes.
An Artist's Rendition Of Pangea
Scientists believe that all the landmasses on the Earth were originally connected as one large continent: Pangea.
An artist attempted to show where modern-day borders would fall on Pangea before the continents drifted apart.
A Glimpse Of Different Lands
No, this faucet isn't showing a road map of Winterfell (or any other mystical realm). What you're seeing is simply the randomized result of corrosion.
Even when the cause is fully understood, it's downright uncanny just how much those lines look like a fantasy map.
A Whirlwind Romance
If you're going to turn your marriage proposal into a photo op, you're going to want a memorable backdrop.
This random field in South Dakota is scenic if a bit boring, but the straight-up tornado in the background elevates it significantly.
Grab The Necessities
If you've ever been woken up by an earthquake and fear that your home may collapse, you know what it's like to run outside after grabbing anything important you can think of.
Most people would gather up kids and pets, along with important medications and maybe jewelry. This guy, though, made sure to grab his PlayStation 5 and nothing else — not even a shirt.
Positively Kubrickian
The stark minimalism of the glossy white backdrop along with the mechanical vibe of the various vents and angles, along with — most importantly — the crimson pool makes this look like a scene from a Kubrick film.
As it turns out, this is just the bottom of a very clean fridge after a jar of beetroot juice sprung a leak.
This Is What The Inside Of A Passenger Plane Used To Look Like
It's shocking to see in comparison to the current neat rows of seats we're used to seeing on planes.
But this is what the cabin of a passenger plane looked like in 1930.
This Computer Store Has Been Left Untouched Since 2002
Since the beginning of the digital age in the 1990s, technology has changed at an extremely rapid rate.
In fact, it's hard to believe the contents of the store were the latest models less than 20 years ago.
The Cherry Blossom Tunnel Of Germany
Located in the town of Bonn, Germany, this street lined with Japanese cherry blossoms is one of the most beautiful in the world.
The trees were gifted to Germany by Japan in the 1980s, but they have a short blooming period, so this is a rare sight.
This Carving Dates Back 10,000 Years
This 10,000-year-old carving of a giraffe was found in the Sahara desert.
It is actually believed that the Sahara desert used to be a lush, green land, meaning that giraffes likely lived in the area back then.
Camouflage At Its Best
Thousands of years of evolution have helped animals become extremely well-suited to survive in their respective habitats.
Not only do owls have 360° vision, but many also blend almost seamlessly into their environments.
This Is A Very Resilient Tree Trunk
The Old Man of the Lake is a 30-foot-tall tree stump, most likely a hemlock tree.
It's been bobbing vertically in Oregon's Crater Lake since at least 1896.
This Is The Rarest Pasta In Italy
Su filindeu is a handmade Italian pasta that only three women in the world know how to make.
It is so difficult and time-consuming to make that it wasn't available to the public for 200 years.
These Are Vietnamese Mossy Frogs
This species of frog is dominantly found in northern Vietnam and southeastern China.
Their skin, which resembles moss on a rock, acts as camouflage from predators, and they curl into a ball when scared.
This Is A Photo Of The Everglades
Approximately 200,000 alligators live in the Everglades, but over 1.5 million live in the state of Florida alone!
Despite popular beliefs perpetuated by films, it is quite rare for alligators to eat humans. They do attack at times, so it's best to steer clear of gators altogether.
A Sundial That Delivers A Readable Time
This sundial was 3D-printed with grooves so that, depending on the heigh of the sun, the light coming through it would create a readable time like a digital clock face in the shadow.
This is pretty cool.
I Never Realized How Small The Earth Is In Comparison To The Sun
Outer space can be really hard for a person who doesn't have a background in astronomy to conceptualize.
So this scale model of the sun vs. the planets of our solar system really adds perspective.
Not Your Typical Grand Canyon
This is a photo of the Grand Canyon found in Greenland, which is a little icier than the one in Arizona.
Its impressive length (more than 466 miles!) was first discovered in 2013 under a giant ice sheet.
In A Galaxy Far, Far Away...
These leftover pieces from a filming location for the original Star Wars movie, Episode IV: A New Hope, were left behind in the Tunisian desert.
The location was used as Luke, the main character's, home.
The First Step To Buying A Neon Sign
Back in the day, traveling salesmen were the main way that companies could sell products to businesses.
This is what a neon light salesman carried in his case to show potential clients in 1930.
Never Underestimate The Power Of A Strong Wind
This tree is located near to Greenough in Western Australia.
There, the wind blows so powerfully and consistently that trees that aren't protected by any wind-breaking objects actually grow sideways.
The Tomb Is Lined With Lead
This is the tomb of legendary scientist Marie Curie located in the Panthéon in Paris.
Her tomb was created with an inch-thick barrier of lead to protect visitors from radiation because her remains are still radioactive to this day.
The Skeleton Of A Stingray
It never really occurred to me that these floppy water pancakes would have any sort of skeletal support beyond a spine.
So this photo simultaneously amazes and terrifies me.
Get This Owl A Modelling Contract!
I don't know how I expected owl legs to look, but it definitely was not like that.
As a predatory species, owls tend to snatch their prey up using their claws which are clearly attached to their long legs.
This Looks Like The Passageway To Hell
A natural sinkhole opened up in the British area called Cornwall and happened to fall into a mineshaft from the medieval ages that went 300 ft. down into the ground.
Wow, that's deep.
This Is The Skeleton Of A Puffer Fish
I originally thought that a pufferfish had the structure of a balloon with a flat skeleton like most other fish.
However, the skeletal structure extends into the spines and expands with the fish as it puffs up.
Crop Circles, But Make It Trees
These odd tree formations are located in Japan.
The trees were carefully planted, trimmed, and maintained over half a century in order to grow into these circular shapes that look very similar to crop circles.
It Turns Out That Sunsets Are Cool From All Angles
This picture shows what a sunset looks like from space.
The red line across the surface is created because at this angle, the sun has to go through more layers of atmosphere, causing the light to refract off of particles in the air and appear more red.
Wolves Are Bigger Than You Think
Luckily, most people haven't been face-to-face with a wolf, so it's hard for the average person to know just how large these relatives of dogs are.
This one lives in a rescue that cares for wolf-dogs who are taken for domestication then abandoned by owners once they get too big.
An Easy Way To Prevent Plastic Waste
This drugstore in the Czech Republic has stations where customers can bring their own containers to refill shampoo, conditioner, body wash, etc.
More places across the world are offering zero-waste shopping options to prevent plastic waste.
This Style Uses Fewer Bricks Than A Straight Wall
It might sound counterintuitive, but this wavy design that's sometimes seen in England uses fewer bricks than a straight wall.
This is because the wave structure adds strength that a straight wall would require at least three layers of bricks to achieve.
These Are Prosthetic Fingers
Most of us have seen a prosthetic leg or a prosthetic arm in our life, but prosthetic fingers are a relatively new medical invention.
They still haven't reached popular use yet.
This Is The Cutest Rendition Of A Skin Suit
Normally, the concept of someone or something wearing a suit made out of skin is terrifying.
But this gecko who is in the midst of shedding his outer layer looks so adorable.
