- [Narrator] We'd all like to think that the world is as
straightforward as it seems. But the reality is that a simple change of perspective can turn
everything you know on its head. With that said, let's take a look at some images that will
change your perception of the world. (upbeat music) Blood Vessels in a Human. From the outside, humans look
like fairly simple creatures. But from another perspective,
it's mind-blowing how intricate the human body actually is. This is a real human hand specimen which was injected with dyed
plastic and left to set. When all the organic material was removed, it revealed the extent to
which our blood vessels map every inch of our being. The smallest blood vessels inside you measure five micrometers. For comparison, one human
hair measure 17 micrometers. In fact, if you line up every blood vessel in the adult human body end to end, they'd measure almost
100,000 kilometers in length. That's enough to circle the
globe twice, and then some. Life Hidden Within. Trees are nature's Diaries. From the outside, they
seem like nothing more than a hardy solid trunk. But if you were to cut one open, shave through the growth rings and around the knots in
the wood, you'd be stunned. What you'd get is a sculpture
of that very same tree in its first years as a sapling from decades or even centuries before. This art installation by Giuseppe Penone was designed to reveal the work of life hidden within the wood, demonstrating the scale of
this older tree's younger self. Turns out trees have a longer memory than a mad ex-girlfriend, who knew. Real Rainbows. Rainbows have been a
meteorological fascination of humans for centuries. And despite knowing a lot about them, most of you are only ever
seeing half the picture. That's because rainbows aren't
arches, they're circles. Rainbows exist thanks to light's
refraction and reflection. When the light hits falling
water droplets just right, it's split into the colors
seen at different wavelengths and is reflected back to Earth at a very specific 42 degrees. From the ground, 42 degrees
is just enough to show you the top of the rainbow. But from the air or at a vantage point, you can get the full 360 degree show. Rainbow Floor. But rainbows don't just belong in the sky. This incredible phenomenon
is known as rainbow sheen. It's created when natural
oils of decaying vegetation are released into stagnant waters and form a thin undisturbed layer on top. Similar to a real rainbow, light reflects off the
surface and appears different depending on the angle it enters your eye. The difference in thickness
of parts of the oil film produce different refracted light rays and these mix after being
reflected to produce a spectrum of color
across the forest floor. Damn nature, you pretty. The Mona Lisa. For a world famous painting
that has its own dedicated room in the world's most renowned art museum, you'd expect Leonardo da Vinci's Mona Lisa to be a fairly large piece of art. But in reality, this masterpiece
is more of a miniature. At just 30 inches tall, the Mona Lisa sits behind
bulletproof, shatterproof glass in its very own room in the Louvre museum where it looks more than a
little out of proportion. With around 10 million visitors a year, which can vary between
30,000 to 50,000 per day, don't expect a quiet trip
where you can strike a pose during visiting hours. Influencers, you've been warned. RH Null. These are enhanced images
of two red blood cells. And despite having this same structure, you can see they differ significantly. The cell on the left is
what would be considered a normal blood cell
carrying Rhesus Antigens. There are approximately 50 antigens that normally cannot be
absent from a person's blood as they cause an immune response. But a rare genetic mutation
means the cell on the right has no Rhesus Antigens whatsoever. This is is a blood type known as RH Null, and less than 100 people on the planet are thought to carry it. Although like O negative blood types they can donate to anyone, they can only receive
from other RH Null donors, of which there are only nine
active in the entire world. Bloody hell. The Giza Pyramids. If you're traveling to Egypt hoping to see the famous pyramids in a sea of ancient desert, you might want to realign
your expectations. Egypt is a modern country, and Giza, where you'd find those
magnificent wonders of the world is the thriving capital city. Expectations, meet reality. Like most cities heavily
reliant on tourism, there are plenty of
modern amenities close by, like Pizza Hut which
you can actually enjoy the majestic view from, and maybe even add in a
slice of your own history. Sarcoma Cancer. There seems to be a preconceived notion of what cancer looks like. From lumps to tumors, they
always seem to be pictured as an addition to the parts of the body. But in cases of bone
cancer, there's no choice but to view it differently
when you see the bone exposed. This is the skull of a human who suffered from sarcoma cancer. The action of the sarcoma cancer cells forms these abnormal calcium
deposits on the bone's surface resulting in a crystal
and feathery appearance of the affected areas. As devastating and painful as this looks, it's rare to be able to identify this from just a surface glance. Never gamble with your
health boys and girls, because you never know what lies beneath. The Ship Shipping Ship. Here's a brain teaser. How do you transport a transport ship if that transport ship isn't water ready? It's not a question people tend to ask, you just kind of assume
they're built all in one place. But what is actually used
is a ship that ships ships. This is the Blue Marlin, a
semi-submersible heavy lift ship designed to transport
more than 75,000 tons across the ocean at any one time. It doesn't just carry ocean liners, it used to help haul back damaged warships that can't make it home
and are too big to tow. And oil rigs built on land
that are then attached to the pipeline. So technically in this image, this is a ship shipping ship,
shipping shipping ships. I'm not repeating that. Golf Balls. Before I tell you what this is, just take a guess at what it could be. They look like the insides of
planets or some abstract art. In fact, this is just a series
of golf ball cross sections. You may think all golf
balls are made the same but the interiors of each
reveal different types are meticulously made in a variety of ways to provide differing
levels of performance. So even though they all
look similar on the green, every golf ball is technically unique. Seven by seven by seven Rubik's Cube. This may just seem like
a slightly larger version of a traditional Rubik's Cube, but there's more than meets the eye to this little puzzle box. There are more combinations on a seven by seven by seven Rubik's Cube than there are atoms in
the observable universe. The actual number itself looks like this, and the largest powered works it work to is called one duoquinquagintillion. I'd try and say the full number of myself but we'd be here for a small eternity. So technically when you hold one of these, you're holding the whole
of the known universe in the palms of your hands. Road Signs. Driving along in a car, you
probably don't think too much about why you're able to
read road signs so clearly regardless of your speed. That's because their writing
has been specially designed to be easy to process. How? Well, just take a look
at the sheer size of them. Highway signs aren't made big just because they cover multiple lanes. But the speed which you're traveling means they must be able to be
viewed from further away so that you have enough time to adjust and prevent last minute hazards. It's odd to think that much
detail goes into something you see every day and yet
you never really considered the true size of it. Either way, I'll take it as a sign. The World's Water. On Earth, there's roughly
1.332 billion cubic kilometers of water. It covers 2/3 of our planet
with over 70% of fresh water locked in our ice caps. But to put that into perspective, if the Earth was the size of a basketball, then all the water in the world would fit into just one ping pong ball. To separate that out even further, if we were to remove all
the fresh drinkable water from that ping pong ball, it would be about the
size of a small bead. And if you poured all
the water in the world into a hole the same size and
shapes as the United States, that hole would need to
be 145 kilometers deep. If you can't imagine what that looks like, just ask your mother. Water Shadows? Shadows are created by an object blocking a light source, right? Then how would you explain this image? Light isn't the same in all mediums and in liquid it acts very differently. The wasp in this image is held afloat by the water surface tension. The cohesive force of the
molecules sticking to each other creates a slight indentation in the water. And this refracts the
light slightly sideways creating shadows at the
bottom of the container. I don't know about you, but
the fact that wasps can float is ruining all perspectives
for me right now. Ouse Valley Viaduct. Does this scene look familiar to you? No, it's not from the film "Inception". Despite looking like a dreamworld doorway, this is actually the base of the Ouse Valley Viaduct in England. The arch vaulting pillars
have been created using over 11 million bricks
to make a well-supported, long lasting bridge across the valley. In the process, they
accidentally seem to have opened a portal into another dimension. This looks like the best
Harry Potter sequel yet. the hand of Miss Wilhelm Rontgen. This old blurry, grainy
photograph may look ominous, but it's actually one of
the most monumental leaps in science ever taken. That is a human hand
and the large black lump is a wedding ring. In fact, this is the hand of Miss Wihelm Rontgen from 1895, and it's the first ever image created through x-ray techniques
designed by her husband, Wilhelm Conrad Rontgen. This picture created a
sensation around the world more than a hundred years ago and revolutionized the way medicine and science have advanced. What you're seeing is the first time a human was able to look inside a body without taking it apart. How incredible is that? Brain Cell or Universe? Anyone who's ever seen a
cauliflower has probably noticed the way it grows kind
of looks like a brain. But did you know the neurons in your brain grow in a similar pattern to
the expansion of the universe? I mean, that's deep. So deep, even science can't explain it. The journal of Nature's
Scientific Reports suggest that these similarities
aren't just coincidence, and the growth of these
systems is influenced by some unknown,
fundamental law of nature. Further to this, the natural
growth dynamic of networks like the internet follow the same pattern. So that means our brain cells and galaxies also somehow
link to Reddit and 4Chan. Well that explains a lot about humanity. Sperm Whales Sleep Vertically. Due to their giant size, sperm
whales can't afford to sleep for a very long as
their need for air means they could easily drown. But evolution has them covered. These gentle ocean
giants are able to sleep for 10 to 15 minutes at a time by swimming down deep and
then slowly and vertically rising up to the surface. Sleeping vertically in their pods means they maintain social contact, so no one is left behind as a
napping snack for predators. Research suggests they spend less than 10% of their daily cycles sleeping, making them one of the least
sleep-dependent animals on the planet. Now that's what I call a power nap. Which one of these images
changed your perception of the world? Let me know in the comments
below, and thanks for watching. (upbeat music)
