Whales are the biggest creatures in the history of our planet. Their influence on not only nature but also humanity and our culture is equally as huge. You wouldn’t think their existence would affect our life, but let’s see what the world would look like if there were no whales! In ancient times, they gave us the concept that three huge whales carry our planet on their backs. Centuries later, they inspired one of the greatest books of the 19th century: Moby-Dick. Fashion could’ve taken a completely different path. But mostly, it’d have to be the effect on the food chain and the rich sea life. Other videos you might like:

The theory of their origin 6:44 #whales #seagiants #brightside SUMMARY:
-The blue whale is the largest and heaviest creature that’s ever lived on Earth and one of the most harmless creatures in the ocean.
-There are all kinds of whale species, and they’re all divided into two groups: baleen and toothed.
-In ancient times, people believed that three huge whales carry our planet on their backs. Whales inspired Herman Melville to write one of the greatest books of the 19th century: Moby-Dick. -People had been hunting whales for thousands of years for their fat, which was used for fuel in oil lamps. That oil was also used to make soaps and cosmetics.
-Baleen was a must-have back in the whaling days. It was pretty much as popular as plastic is today. Without whalebone, we wouldn’t have come up with corsets. -Without whales, seafood would be a luxury, as the number of all crustaceans and mollusks would noticeably decrease. Even ordinary fish would feel the consequences.
-If whales disappear, the ocean will also lose … singing. Male whales sing songs to attract females, and females sing lullabies to reassure their offspring.
-By the way, if there weren’t any whales, there couldn’t be dolphins either. As well as porpoises, they are a type of whale!
-There is a theory: millions of years ago, the animals that whales would later come from actually walked on land! They looked like huge pigs or hippos. It took millions and millions of years of evolutionary process for them to move into water. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

Why There’s No Hair on Our Bodies Any Longer
Australopithecines are believed to be our direct ancestors. They are primates, like us, but this far in the past they look nothing like humans: they’re short, with more prominent foreheads, flat faces, and … completely covered with hair. Humanlike apes were still hairy, though, but in about half a million years, the upright-walking primates have finally lost some of their hair. Not all of it, but that’s a start! Why’s that? Let's figure out! Other videos you might like:

When and why primates lost some of their hair 2:52
These guys resemble us a lot 4:06
Why we don't have hair on our palms 6:44
And what about our heads? 8:01
‘Hello’ from the distant past 8:25 #hair #humanbody #brightside SUMMARY:
– Australopithecines lived in the trees, like many modern primates do, but what distinguished them from everyone else was that they learned to stand and walk upright.
– Forests have given way to expanding savannahs, and living off the trees has become harder. To find leaves and fruit, they had to cover bigger and bigger flatland areas, so in the end they decided it just wasn’t worth it and found new food sources on the groundю
– Another leap of half a million years and finally, the upright-walking primates have lost some of their hair.
– That’s why, according to the most popular theory, the hominins started getting rid of their body hair: they needed open skin to sweat.
– Let’s jump ahead a bit more — say, a million years further. And here we have hominins that have already lost their hair so much that they resemble modern humans a lot.
– Other mammals, including primates, did not lose their hair and fur, so hominids must’ve had some pretty good reasons.
– Sweating helps them keep their stride for a long time. And they’re the only bipedal hunters who can follow their prey for hours on end, until it falls from exhaustion, leaving itself to the mercy of its stalker.
– And one more thing that this general hair loss doesn’t seem to explain is why humans still have so much hair on their heads but not, say, on their palms or soles of their feet.
– Hairs would slip and you’d simply drop the bar, however hard you may try.
– One of the theories says that we’ve retained thick hair on our heads because of our upright position: when we stand, the most exposed to the sun is exactly the head, and the layer of hair helps protect the skin and brain from its heat.
– Some humans have kept more genetic material from their ancestors than others. According to one version, we’re now moving to a time when men and women will be mostly similar in size and looks.
– And there’s even a genetic anomaly that’s called hypertrichosis, which is believed to be a ‘hello’ to us from the distant past, when humans were still hairy all over. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

Scientists May Have Turned Back the Arrow of Time
Through the years, people have collected a whole dictionary of phrases about wasting time and how it can never be turned back. It would be a shame to lose them all if some scientist were to prove that time is reversible. Actually, it seems like that already happened! Well kinda… Time travel might just be real. A team of Russian scientists stated that they were able to reverse the state of quantum in time for a minuscule fraction of time. For this purpose, they used an IBM quantum computer and innumerable attempts, 85% of which were successful in a simple system, and only 45% in a system that’s a bit more complicated.

What really happened during the experiments 1:24
What's the arrow of time? 🏹 3:17
Quantum teleportation is real! 4:03
How a quantum computer works 4:24
So what can be teleported? 8:29 #timetravel #future #brightside SUMMARY:
– The concept of the arrow of time is an integral part of nature’s laws, like the laws of thermodynamics for example.
– Basically, it means that time always goes in only one way: from past to future as everything is constantly, irreversibly changing its state and condition.
– Quantum can be in two states simultaneously. Quantum teleportation was proved to be real, and now it seems like even time itself isn’t truly safe.
– A quantum computer is a real miracle of science, with vast processing power that comes with one main difference from the classic computers: classic silicon-based computers use bits to store information.
– Quantum computers use quantum bits or qubits instead of bits. These are also the most basic units of information for a quantum computer.
– When bits can only be in one of the two possible states, qubits use quantum particles, which can be not only in one of two states, but also in both at the same time.
– For a time-reversal experiment, only two qubits were used, and even if it wasn’t true time-reversal, it’s a giant breakthrough for quantum computing itself.
– The result of these experiments shows that by applying a special equation to qubit particles, they can effectively step back in their state like after a good sip from the Fountain of Youth.
– A group of computer scientists was able to basically transport a particle through space in an instant. One moment it was there, and then it blinked in another place!
– As we already know, scanning a particle applies stress on it, and therefore disrupts its state almost completely.
– Information about the properties of this particle was then sent to the second particle and it inherited them all, effectively becoming the first particle.
– None of the particles were really transported anywhere, but the information about them was teleported.
– In basic terms, teleportation means scanning and disrupting something in one place and reassembling it in another with the use of information from the scan. Therefore, what scientists saw there was still teleportation. – Quantum teleportation, just like quantum time-reversal, can’t be used on anything except particles, like electrons and photons.
– But who knows what could be possible if all this new knowledge could be used to build the first practical quantum computers. With their processing powers, we’ll be able to take chances even on teleportation and time machines.

Don’t Use Candles During a Power Outage and 14 Other No-Noes
Whether it's a thunderstorm, a heatwave, or just some curious animal or a bird. No matter who or what’s to blame, suddenly bam! You don't have electricity anymore. And it’s dark. What are you gonna do now? Well, there are things that can make this situation even worse, so keep them in mind. Do you know, for example, that it can be dangerous to come close to pooling water? Many power outages are caused by storms. So be careful and stay away from pooling water, because it can hide not only fallen tree branches but also power lines. It’s better to stay inside till authorized work crews clear the area safely! Other videos you might like:

Don’t come close to pooling water 6:01
Don’t grill indoors 6:28
Don’t keep a generator at home 6:57 #poweroutage #storm #brightside SUMMARY:
– Look for any damage on the panel, but be careful and don't touch it, just in case. If the problem isn't the breaker, check the service wires leading to the house.
– Unplugging electronic appliances, such as microwave, computer, washing machine, and so on, will save them from any possible damage from an electrical surge when the power comes back.
– When it's closed, the cold air will stay inside, preventing your food from spoiling. So open it only when it's necessary.
– Don't use candles. Lighting them isn't the best option since they don't give off much light. But the main problem is that candles can cause a fire.
– If your whole neighborhood doesn't have electricity, then gas stations probably won't be an option since they need the power to pump gas from their tanks to yours. That's why it's important to keep the tank full before a storm hits.
– Many people have no idea how to open the security gates manually. Contact the security office to find out. This way you can plan to leave your neighborhood easily if need be.
– It’s better to close all your apps and dim the backlight to save the battery. When there’s no way to charge the phone, you definitely don’t want to be left without the option to make a call in some emergency.
– Though you’ll have hot water in reserve, its temperature will keep dropping. So if you want to take a shower do it as soon as possible.
– Some think that broken traffic lights serve as a four-way stop. But actually, they work the same way as a four-way yield.
– During a neighborhood-wide blackout, your credit cards will be pretty useless. That’s why it’s important to have some cash at home.
– If your house is rather old, look for uninsulated pipes in your basement, garage, or outside the building. If you find them, wrap them up in old blankets or towels.
– If you have a gasoline powered generator, then your chances of feeling pretty comfortable during a blackout rise. But it emits toxic carbon monoxide, so it should stay away from the house.
– If the power outage caught you off guard, use your car to charge your phone or any other mobile devices.
– Have a dozen or so of those small solar powered garden and sidewalk lights planted around the outside of your house. – Keep a battery-powered radio at home. Cell phones might not last long enough during a long-term blackout.
– If your main issue is to stay warm, then choose one room in the house where you’re gonna use alternative heating and close off all the others. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

That’s Why Most Erasers Are Pink
Have you ever woken up at 3 AM with a flood of urgent questions in your mind? Like, how do barcode readers work? How did bubble wrap appear? And, most importantly, is there a reason erasers are pink? Ok, they now come in all colors and shapes, but what about that classic bubble-gum hue? History’s got all the answers!

How about to rent a pineapple? 7:46 #factsyouneverknew #amazingfacts #brightside SUMMARY:
– Ever paid attention to those metal or plastic tips on the ends of your shoelaces? They’re called aglets. They appeared in ancient Rome, where people made them out of glass or stone.
– When the first computer mice appeared, producers referred to them as turtles.
– The popular toy has been around for over 70 years, but there’s more to the Slinky than stair-time fun (and lots of tangles): its older metal version used to serve as a makeshift antenna for engineers and soldiers.
– A US 1-dollar bill usually lasts for only 18 months – after that, it must be withdrawn from circulation and replaced.
– T-shirts were invented at the beginning of the 20th century. In 1904, Cooper Underwear Company advertised them as a perfect product for bachelors who couldn’t sew or reattach buttons to their shirts.
– In 1957, engineers Alfred Fielding and Marc Chavannes decided to seal two shower curtains together with tiny bubbles of air stuck in between. It was supposed to be a cool new idea for a wallpaper!
– When a stand-alone eraser appeared in 1916, it was made mainly of rubber and pumice. Pumice could be white or red, and the color of an eraser depended on the hue of this volcanic rock.
– Electric fans don't actually cool the air. What it does do is cool your skin! The device speeds up the evaporation process, making sweat on your skin colder.
– Rice is the product people have been cultivating for the longest time: from 12,000 to 15,000 years. It first appeared in ancient China's Pearl River Valley thousands of years ago.
– You might have noticed that some cables have chunky cylinders on them. These cylinders are called ferrite chokes. Without them, cables turn into antennas that can pick up and broadcast electrical interference.
– George de Mestral, the Swiss inventor of the popular quick fastener, once noticed how burs would stick to his dog's fur and his own pant legs. This inspired him to come up with an idea of creating the same effect for fabric.
– Barbie saw the light of day in 1959. And in the 1960s, the legendary doll got a fictional biography published in a series of novels.
– Despite what I used to believe, barcode readers aren’t reading the black parts of the code but the white ones!
– In 1493, Christopher Columbus brought some pineapples to Europe. It became a symbol of status, and people who couldn't afford to buy one, rented pineapples for a night to show them off at their parties!

7 Unexpected Uses for Incognito Mode
Have you ever had the feeling that someone was watching you? You know, that little bit of uneasiness in the back of your mind that forces you to turn your head just to make sure. Well if you spend time on the internet, that’s almost certainly true. Search engines like Google, Bing, and Yahoo make most of their money selling advertising space. But advertisers don't like paying for ads that don't reach their customer base. So to solve this problem, search engines like to track their users. It’s understandable that some people don’t like the idea of being tracked. For that reason, most browsers now feature an incognito mode to let you search without surveillance. Here are seven lesser-known reasons you might consider browsing incognito. Other videos you might like:

Controlling video suggestions 4:37
Using multiple accounts 5:28
You want to look like a fresh user 6:11
Gift shopping 7:20 #privacy #computertricks #brightside SUMMARY:
– This is the safe thing to do any time you're on a device other than your own. Whether you’re sending an email, checking your balance, or just logging into Facebook, you don’t want strangers messing with your stuff.
– While all this writing about espionage might just be making you paranoid, you still don’t want that suspicious search hanging around in your browser history.
– By turning on private browsing, you can, at the very least, save yourself some awkward conversations if anyone happens to get a look at your search suggestions.
– Maybe you have a rash and want to know if it's something to see a doctor about. Fortunately, you had the forethought to browse in incognito mode, and you can move on with your life, free from reminders of your itchy episode.
– Private browsing also comes in handy if you find yourself googling the answer to a question you feel a little bad about not knowing. Who’s on the one-hundred-dollar bill? What’s the Queen’s Name? Is there an apostrophe in “don’t”? How do you even spell apostrophe?
– To keep weird or just unwanted videos from cluttering up your feed, you might consider browsing incognito. You won't have easy access to things like your YouTube subscriptions, but it will keep one-off watches from haunting your homepage.
– Signing in and out of multiple accounts can be a real hassle, and if you’re answering that many emails, you're clearly a busy person. To save some time, try opening each account in a different private browsing window. Instead of having to go through each account one by one, this trick allows you to check and respond to all your messages at once.
– It doesn't just prevent your browser from saving logins and history, it also disguises your computer, hiding it from programs meant to track your usage.
– Some booking sites keep track of who's looking at what destinations. This allows them to adjust pricing accordingly, potentially charging more for trips you’re seemingly sure to make.
– While browsing in incognito isn’t guaranteed to save you any money, it’s a useful trick if you want to make sure you’re getting the best deal available. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

What If You Had to Live Underwater for Years
How long can you hold your breath underwater? Aleix Segura Vendrell, a professional free diver from Spain, managed to hold his breath for 24 minutes and 4 seconds. I know, it's hard to wrap your mind around. But it got me wondering: could people live underwater? Come to think of it, living underwater would have loads of advantages. For example, hurricanes and tsunamis wouldn't be dangerous anymore: in a deep-water house, you wouldn't even feel the raging waves. You wouldn't need a swimming pool if you decided to throw a pool party. But if people had to spend their lives in the water, they’d have to evolve and turn into a completely different species… Other videos you might like:

Can underwater cities exist? 4:29
What would we eat? 6:27
Btw, this technology does exist! (Wait, what?!) 7:50 #underwater #whatif #brightside SUMMARY:
– Your muscles are built to help you move on land. That's why, if you spent all your time underwater, they would atrophy, and you’d become incredibly weak.
– Your limbs aren't the most effective implements when it comes to swimming. That's why you’d also have to grow fins.
– At a depth of 650 ft, it would already be too dark for you to see anything. And don't forget about the water pressure!
– Your ears and eyes have been developing for thousands of years to work in the air. That's why underwater communication would be a huge challenge.
– Scientists still don't understand the reasons completely, but when you spend too much time in the water, your skin starts to break down.
– However, scientists don't deny that one day, genetics might go as far as to modify humans so that they’re able to live underwater!
– Underwater cities and colonies wouldn't be built deeper than 1,000 feet. Any deeper than that and the structures, along with their inhabitants, would collapse under the incredible pressure.
– Plus, people wouldn’t only have to solve the problem of oxygen supply, but also figure out how to maintain the correct ratio of various air components.
– One of the main problems in underwater colonies would be an infection. If someone got sick in such an enclosed space, the virus would spread very fast.
– But at least underwater colonies wouldn't suffer from a lack of food! Living on the ocean floor, you’d get access to all the seafood you can find there (and that's a lot!).
– People could set up farms raising shrimp and fish, which are perfect sources of protein.
– It would be possible to grow special plants for making ecologically friendly fuel, such as biodiesel, more cheaply. – The technology to make underwater colonies possible already exists! These colonies can easily support up to 100 people, and scientists are working on ways to make this number bigger. – The main problems so far are creating working evacuation routes, figuring out how to get enough air, and how to make the environment humid enough.

What If Earth Started to Spin Backwards
Our planet rotates around its axis from west to east at a speed of over a thousand miles per hour at the equator! And this pattern has lasted for billions of years since the Earth was formed. But “what if” one day, our planet suddenly started to rotate backward, from east to west? It would be one thing if the Earth's continents and oceans were situated symmetrically against the equator when the change of the direction happened. In this case, the only change people would notice would be the climate, which would turn into a mirror image of the current one. In other words, there’d be no dramatic changes. But since life on our planet is rarely about symmetry, the effects of the Earth rotating backward would be way more complicated. Other videos you might like:

What If the Earth Stopped Spinning Right Now https://www.youtube.com/watch?v=Pex2gaCJ954& TIMESTAMPS:
What if it happened SUDDENLY 1:02
What if it rotated from east to west right from the beginning 2:15
A completely different species instead of us?! 4:21
What if the Earth's core cooled down 5:28
What if there were no magnetic field 5:56 SUMMARY:
– In the case of an abrupt switch of the direction, an instant change in speed would make about 2,000 miles per hour!
– Buildings and other man-made structures would collapse, sending tons of debris into the air and creating chaos.
– In short, the Earth would turn into a gloomy, muddy mess.
– The different spinning direction of the planet would create unexpected weather conditions on all the continents, and the Earth itself would be a totally different place!
– Western Europe would be plagued by severe, freezing winters every year. And, vice versa, Russia would warm up and lose the title of one of the coldest countries in the world.
– The area from the Middle East to Central Africa would be covered with lush, dense forests. And the rest of the deserts would be either covered with grass or scattered trees.
– There would be much more greenery on our planet, and, therefore, more oxygen for everyone to breathe.
– Now, the ocean is swarming with phytoplankton bacteria. But on that different Earth, instead of plankton, cyanobacteria would dominate.
– The chances are high that on a backward-spinning Earth, people would be replaced with a completely different species.
– Somewhere incredibly deep beneath the surface of our planet lies the Earth's core – a ball of scorching-hot iron which is surrounded by boiling liquid metal.
– One of the things that makes life on the Earth possible is the geomagnetic field. This very field is created by the Earth's core!
– If there’s no magnetic field, there's also no atmosphere! That's why some time later, the Earth would start to resemble Mars a little bit too much for my liking.
– The eternal cold and lack of oxygen would either finish us, or prevent us from living normal lives.
– The Earth would probably see a radioactive wave onslaught, which would overheat it to a degree at which it would become uninhabitable. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

You See 6 Buttons Every Day But They Do Nothing
So, you tap a button and something happens — that’s how the world works, right? Well, not exactly. The world is actually filled with buttons that are only there to seem like they do something, while in fact being useless. And not only buttons — there are all kinds of things that are there for no apparent reason. If you live on, say, 15th floor and you’re in a hurry to get home because your bladder is about to burst, for example, you’ll probably feel fine running up the stairs. But if you decide to wait for the elevator instead, you’ll smash that door close button until the doors finally close. Which they will do awfully slowly. Well, did you know that in the US, these buttons don’t work at all? Other videos you might like:

– Transport authorities sometimes switch off the functionality of these traffic buttons on purpose. In New York, for example, there are 1,000 of them, but currently only 100 actually work when you press them.
– Such buttons have an important psychological effect: doing something feels better than not doing anything. When you press the button at a crossing, you feel more assured that the light will eventually switch to green.
– Not to disrupt the work of the whole network, many of the traffic control switches were turned into placebo buttons.
– The elevator doors will stay open for no less than the time appointed to them, no matter how much or how long you mash that button.
– So unless you’re an emergency service worker or just happen to know the override code, you won’t be able to make the doors close faster.
– If you live outside the US, though, your chances of getting a working close button are much higher. In many countries, there are no such strict regulations, so you can easily find an elevator where, if you press the door close button, the doors will actually shut immediately.
– Most office buildings have a central heating, ventilation, and air conditioning system (HVAC for short). And the thing about this central system is that you can’t actually affect it from anywhere outside the control center.
– In fact, there are two general types of office thermostats: one that is total placebo and one that is only partially so.
– The partial placebo thermostat has a little bit of sway: it can change a couple degrees in both directions, but no more than that.
– Whenever you download a file from the Internet or install a new app on your device, you see a bar that informs you of how much time you have left to wait. Ever seen it stuck at 99% for, like, forever, though? Yeah, it’s exactly what it seems: the progress bar is always wildly inaccurate.
– When you run, you burn calories for sure, but the precise amount depends on various factors, such as your weight, overall fitness, and body fat percentage.
– This counter is, once again, only there to assure you that you’re doing everything right. The downside of this is that even if you’re not doing it right, the treadmill won’t let you know.
– When a call attempt failed, the system didn’t tell the caller about it, but simply switched to another recipient instead. So when somebody took the phone on the other end of the line, you apologized for dialing a wrong number and tried again. This way, you didn’t feel the frustration of having a failed call.
