What If World War 3 Happens Tomorrow?

What If World War 3 Happens Tomorrow?

What If World War 3 Happens Tomorrow?

What If world war 3 happens? or What if world war 3 happens tomorrow? Human history has been full of battles and wars some big and some small. But if World War III were to happen. It might be Humanity’s biggest battle yet. Advanced technology, massive troops, and many more intensive strategy would all be involved.
But why would Something like this happen? What countries would join in and how would this war be fought? Welcome and here’s

What would happen if we had World War three?

People have talked about possible world war three for decades. It’s almost started in the 1960s during the Cold war between Russia and the United States. But thankfully we managed to avoid that. But let’s say we aren’t lucky enough to avoid it next time then when might World War 3 happens.

What Reasons could start a World War?

  • Prominent political figures getting killed
  • Intelligence threat
  • Fighting over valuable resources
  • Religious Wars
Talking about it like this makes the chances of a war happening sound likely but the chances are actually a lot lower than you think. Since 1945 the world has seen many different battles. Vietnam, Afghanistan and dozens of different Civil Wars.
We should keep in mind that in order for a World War to happen, It needs to involve the entire world and the structure of the world is changed even more since 1945.

Countries simply aren’t as closely Allied as they used to be. Militaries are even stronger more skilled than they were as in previous world wars. It’s most likely that Millions of people would die and the Earth would take decades if not centuries to recover.
Especially with some of the weapons and tools, the countries would be using in today’s age. Soldiers on the ground might have exoskeletons. These are Metal Frames around the Soldier’s body that augment their strength.
Although this probably won’t turn them into RoboCop. It would make it easier for soldiers to carry heavy equipment over long distances.
Weapons that can bend around corners might also be a possibility and instead of seeing the war fought in the sea or the sky it could actually be fought in space.
Militaries could fight over weaponized satellites that could affect what’s below them. Although a lot of this stuff sounds like something out of a sci-fi movie. We should keep in mind that these weapons are scary and hopefully no one will ever need to use them.
Afterall things like this are meant to kill people but there may not be many soldiers on the ground. The war of the future might be fought on computers, drones, artificial intelligence, and robots could be the only things on the battlefield. There’s also a chance that acts of war in the future might not involve any violence at all hacking into other country’s computers as well as power grid shutdowns are all a possibility.

What would this war be about anyway?

It could have to do with resources specifically water. Since freshwater is such a scarce yet valuable resource, nations may begin to fight over it as it continues to deplete.
Hopefully, World War 3 won’t go on forever. So how could it end? Well, one reason and the main reason why a World War hasn’t happened yet has to do with these things, during World War II the United States dropped nuclear bombs on Japan killing over 100,000 people the cities involved took decades to recover.
Nukes used in World War II would pale in comparison to the modern nukes we have today. Oh, and by the way, there are nearly 14,000 nuclear warheads around the world held mostly by America Russia and China. A nation can have all the resources people and strategy they want but if a Nuke gets dropped on them, then it’s game over and if one country drops a nuke what’s to stop another country from doing the same and then another and another and soon the world would be destroyed.
So who would win this war? Absolutely? No one. a full-on World War 3 would have a massive impact on the world as a whole it’s safe to say that the world would never be the same. but try not to lose sleep over this after all a third world war like this with dozens of countries involved is incredibly unlikely to start tomorrow.
If two countries get into a fight, it’s more likely that other countries that aren’t directly involved will stay that way and let the other nations fight for themselves. Wars are terrible, let’s try to avoid them.

18 Things Designed for a Different Purpose

18 Things Designed for a Different Purpose

18 Things Designed for a Different Purpose

You know, once upon a time, I spotted a tiny groove on the bottom of my favorite coffee mug. Was it broken? Nope, it looked as if it had been made that way! And that’s how this crazy obsession started.
After googling this question, I discovered that tons of things I used every day without thinking twice — were equipped with tiny gizmos I’d never noticed! And here are 18 discoveries that impressed me the most.

1. Brushes on Escalator Sides

Um, no, they aren’t for polishing your shoes. In fact, these brushes serve an important safety purpose. You might have heard that most accidents happen when people get their bags or clothes stuck in escalators because they stand too close to the sides. But when there are nylon brushes on both sides, you can’t help but keep your feet away from the escalator’s skirt panels. The result? No accidents!

2. “57” on Heinz Ketchup Bottles

amazing facts

I was dumbstruck when I found out that the number “57” on a Heinz ketchup bottle had nothing to do with the product label! The truth is that the place with the numbers is the sweet spot you should tap to get the ketchup flowing! So, stop banging the bottom of your sauce bottle already and hit the “57”!

3. Pompoms on Beanies

amazing facts

Aren’t pompoms attached to beanies to add an extra touch of cuteness? Apparently not. French sailors were the ones who invented this style, and pompoms actually served a very practical purpose. They prevented the sailors from hitting their heads against the ships’ low ceilings. Later, the pompom design was adapted by army troops, and that’s how they ended up decorating our beanies!

4. Slots on Measuring Tape

You’ve probably noticed that on the end of almost any measuring tape, there’s a metal stub with a small slot. If one of your hands is occupied, you can use this slot to hook your measuring tape over a nail head and continue your calculations – the tape will stay in place. Also, the stub is often serrated on one side so that you can make marks without having to use a pencil.

5. Grooves on Toothpicks – groovy toothpicks- take your pick.

amazing facts

While I was doing my google research, I also found out that I’d been using toothpicks the wrong way! Now, I’m talking about toothpicks with grooves at the flat end. If you don’t have anywhere to put such a toothpick after using it, snap off the flat end at the first groove and put it on the table. Now, you can balance the used portion of your toothpick on the grooved part so that it doesn’t have to touch the table.

6. Grooves on Cup Bottoms

amazing facts

It turns out that a little groove on a cup or mug bottom serves several purposes! First of all, it lets cool airflow beneath the cup. It saves your favorite coffee mug from cracking when it gets heated up from the hot beverage. What’s more, when you wash cups placed upside down in the dishwasher, the grooves make sure that water doesn’t stagnate in the cup bottoms and spill all over your feet when you take the cups out. How thoughtful!

7. Holes in Soda Pop Tabs

amazing facts

What could be simpler than a can of soda?  Don’t be so sure, the thing has its own secrets! For example, pay attention to the tab you pull on to open your beverage. Do you see a reasonably large hole in the middle? Let me introduce a designated place-holder for your straw. The only thing you need to do is to spin the tab around so that it’s over the can opening and push your straw through it. Now, who would have thought?

8. Little Dot Near the iPhone Camera

amazing facts

Despite what most people think, the tiny dot next to the camera on an iPhone is NOT the flash! Brace yourself – it’s one of the three microphones that starts recording once you switch on your back camera. It also helps to eliminate background noises when you’re recording videos in crowded places.

9. Holes on Gas Cans

amazing facts

You might have wondered why most gas cans have two holes with caps, one bigger and one smaller. Before, I thought that the little hole is used when you pour something into a smaller container, but I was wrong. In reality, you’re supposed to uncap it before you pour the gas inside the bigger hole to prevent it from “glugging” and spilling on your clothes and the ground.

10. Holes in Pen Caps

amazing facts

Honestly, I used to think that this little hole in the caps of most pens is just an offbeat way to keep the ink flowing. But no! Apparently, pen manufacturers know more about little kids than you can imagine. For example, they realized that one day, a child might end up choking on the innocent-looking pen cap. And to prevent the little ones from suffocating, they started to place holes in pen caps, so that even if one gets stuck in a child’s throat, the air can still get into their lungs.

11. Childproof Prescription Bottles

amazing facts

Ever got super frustrated when trying to open one of those childproof prescription bottles? Then you’ll understand my relief after I found out that there’s an easier way. If you don’t have small kids around, turn the lid on the bottle upside down and there you go! It’s no longer childproof.

12. The Ridges on “F” and “J”

amazing facts

The small ridges on letters “F” and “J” on your keyboard are made so that you can type without looking down at the keyboard. This way, you’ll always know the initial position of your index fingers; and after that, it’s all about your muscle memory.

13. Hole in a Padlock Bottom

amazing facts

This tiny hole has a very important task: it helps to drain water from the outdoor lock after the rain, which prevents the thing from rusting and clogging. On top of that, you can also use this hole to oil the lock’s hinges so that it doesn’t get stuck. You should also remember that if a lock doesn’t have this small hole, you should only use it inside.

14. The Gas Gauge Arrow

amazing facts

The next time you drive your car, pay attention to the little arrow next to the fuel tank sign on the gas gauge. The direction it points in isn’t random. The arrow shows the side of the car where your fuel tank is. Believe me, you’ll see the true value of this feature as soon as you rent a car and drive it to a gas station!

15. Fabric Squares That Come with Clothes

It puzzled me to no end that every time I bought a new shirt or a pair of pants, I found an attached Ziploc baggy that contained a tiny piece of matching fabric and a button sewn on it. Well, the purpose of an extra button is pretty clear, but what with the fabric? The shocking truth is that you’re supposed to try out your cleaning products on this piece of fabric first, so you don’t ruin the whole thing when you decide to wash it!

16. Plastic Lids

amazing facts

At first sight, everything is obvious about plastic lids on disposable cups – they keep your beverage inside, right? But that’s not all they’re capable of! As soon as you find a cozy spot and get ready to sip on your drink, you can use the lid as a coaster! If you look attentively, you’ll notice special ridges that snuggly hug the bottom of your cup. Each lid’s size fits the corresponding cup’s bottom.

17. Notebook Margins

amazing facts

Well, I have to admit that this fact left me outright flabbergasted. It appears that originally, margins weren’t created for making additional notes! They used to protect your work from rats! In those times, rats were common residents in people’s homes, and they loved to snack on paper. That’s why, by leaving margins wide, manufacturers safeguarded the writing on the outer edges. Ah, rats!

18. Side Holes in Converse Sneakers

amazing facts

I have to make a confession – I’m an avid sneaker collector. But even though I have tons of Converse All-Stars, I could never figure out the purpose of the two extra holes located on the side next to the sole. I mean I read somewhere that they were for “additional airflow,” but seriously? Two tiny holes? It turned out I was right in my skepticism, and the holes are actually for laces. Since sneakers were originally invented for basketball players, this interesting design allowed them to accommodate any player’s foot. They just needed to lace their sneakers in a way that was most comfortable for them. 
So there you have it! Pretty particular purposes for puny parts of personal possessions. How about you? Do you know about other things with hidden purposes?

Only 1 Gram Of This Material Is Worth Over 💰 25 Billion Dollars. But Why?

Only 1 Gram Of This Material Is Worth Over 25 Billion Dollars. But Why?

What is antimatter?
The question is Which is the most expensive material in the world? So commonly when we think of the most valuable material in the world our minds tend to center onto gold and while gold is very expensive at a current value of $50 per gram.
There are other materials that are significantly more expensive. Drugs like Heroin, Cocaine, and LSD for example, are the most expensive drugs in the world by sheer weight, far more valuable than gold is.
The market value for diamonds per gram is even more prohibitively expensive, but even this is nothing compared to the most valuable material currently known to humanity.

Antimatter: So what is Antimatter?

what is antimatter

To put it simply, antimatter is the opposite of regular matter. Down at the atomic level, antimatter is made up of particles and atoms just like regular matter is.
The only difference is that they have the opposite electric charge. Protons and antimatter are negative and called anti-protons while electrons are positive and called Positrons.
Whenever antimatter and matter touch one another they instantly annihilate each other in a 100% efficient release of energy. This pure energy release is why antimatter could prove to be extremely useful.
The most efficient nuclear weapons, for example, convert a mere 7% to 10% of their mass into energy while antimatter to matter collisions release 100% of their mass into energy.
If you somehow were carrying one gram of antimatter about the size of a raisin and dropped it on the ground. It would create an explosion greater than both the Hiroshima and Nagasaki nuclear explosions combined, easily enough to destroy an entire city.
Smaller-scale assassination weapons may be more economically feasible, however, like the theorized antimatter bullet, which would essentially be a regular bullet but with a tiny 1 billionth of a gram of positrons attached to the tip.
Upon impact, the bullet fired from a rifle would be capable of destroying an entire house, tank or any other similar-sized object. But antimatter has several other uses beyond just military ones.
Antiprotons have also been shown in several studies to have the potential to treat certain kinds of cancers and antimatter could also be used as a fuel source for interstellar travel.
It is conceivable that using antimatter as a fuel source could propel a rocket with humans onboard to about 50 percent of the speed of light, which is fast enough to reach the nearest star to earth in just a little over two years.

So why haven’t we created enough antimatter yet to do any of these incredible things?

The answer is because antimatter is incredibly rare, difficult to produce and prohibitively expensive. Currently, It appears that nearly the entire observable universe is made out of regular matter and while it is possible that there could be entire galaxies made out of antimatter.
We have so far not been able to detect any. Antimatter is produced naturally in Earth’s outer atmosphere when high-energy cosmic rays impact it. But the amount produced is tiny and lasts only briefly before it comes into contact with regular matter and annihilates itself.
The only practical means of acquiring antimatter so far have been to produce it artificially ourselves, but even this method is incredibly difficult and expensive.
The Large Hadron Collider operated by CERN in Switzerland, for example, one of the most expensive and complicated facilities ever built is capable of producing 10,000,000 antiprotons per minute when fully operational.

what is antimatter

That sounds like a lot but it’s actually a laughably tiny amount. To produce just a single gram of antimatter at that rate of production, it would take CERN roughly 100 billion years to complete.
Production is only the first problem though, storing it is perhaps an even larger problem since antimatter annihilates matter instantly. You can’t just store it in a regular container, you have to suspend the material without it coming into contact with anything and so far, CERN has only succeeded in storing antimatter atoms for a record 17 minutes before they became annihilated.
Since just one gram is enough to obliterate an entire city, safety precautions and storing the material and keeping it in safe hands would be of the utmost importance. And we’re not even sure how exactly we would store such a large amount in the first place.

Estimates on how much antimatter costs to produce vary greatly.

In an article written by NASA Godard in 2006, a figure of 25 billion dollars per gram is cited while in another NASA paper written back in 1999 a figure of sixty-two point five trillion dollars per gram is cited Which is about 83 percent of the entire global GDP just to produce one single gram.
For reference, the Manhattan Project which developed the first atomic bomb cost twenty-three billion dollars adjusted for inflation And just like creating the atomic bomb did, creating antimatter in large quantities if ever that’s possible, would open up a new Pandora’s box that we couldn’t close once we open it. We would have to live with the consequences of living in a world with abundant antimatter both positive ones and negative ones.

What If There's No Internet for 24 Hours?

What If There's No Internet for 24 Hours?

What If There's No Internet for 24 Hours?
Ever imagined What If there's No Internet for 24 hours?. Imagining a world without the internet is impossible these days. My intense curiosity led me to research everything that could go wrong if the internet is not working. To summarize each and every problem that could arise because of "No Internet Connection" I've made a Story. So, let's find out what will happen If there's no internet for 24 hours
It’s 7am, and the sound of your alarm wakes you up. You reach over to the nightstand to pick up your phone. With your eyes half-closed, you notice you don’t have any new notifications. “Hmm, that’s weird.” But mostly, you’re more concerned with getting some coffee in you first!
So, you get up, grab a quick shower, and head downstairs. After you’ve gotten some breakfast and coffee, you grab your tablet and see the same thing: no notifications.
You also notice there’s no Internet connection. It wasn’t just on your phone but all your devices. Before checking your router, you try the old fashion’ “turn it off and on again” technique. Of course, that didn’t help. So, you head over to the router and see a blinking red light. The 4G isn’t working either.

Morning chaos

“Ugh, great. Gonna have to call the service provider.” …Eventually. For now, it’s 7:45, and you’re already running late for work. You decide to take a cab – maybe it’ll save some time. You automatically open the app on your phone. Oh yeah, it doesn’t work. No connection.
“Could this day start out any better?” you think sarcastically to yourself. So, you run to the nearest bus stop, which is about 20 minutes away. 20 minutes that you really don’t have right now. Winded, you get to the stop only to see the timetable screen blinking “NO SERVICE.” Now, that’s either because they can’t track the buses and the servers can’t access their schedule, or because there aren’t any today, to begin with.
You notice the people around you for the first time. They’re all looking at their phones in frustration, some have even struck up a conversation. Nobody has the Internet… That’s the first moment when you feel the panic rising in your chest.
“If it’s not just me, then it could be serious…” You spot a cab a few feet away and hop in. But GPS obviously isn’t working, and there’s mad traffic on the road – even with all the signs around to help! Horns are beeping from every direction, and it’s as if the chaos is getting worse right before your eyes as you stare out the backseat window.
When you finally get to your office building, the cab driver’s voice almost jolts you. “$16.50!” You reach for your card without even thinking. But guess what! That doesn’t work either. So, you have to dig in your wallet and hope you’ve got some cash on you. You have a 20. Yes! At least some luck!

It’s better to take the day off

It’s almost 8:30 – yep, you’re half an hour late. Everyone else is already there when you walk into the office. Right from the get-go, you’re already not that surprised to hear the talk of the day, “Internet’s down.” Someone’s talking about the stock market is at a standstill.
Another is talking about how hospitals everywhere are struggling to access medical records since everything was online. You head over to your desk and sit down to start your computer, wondering if you should’ve bothered coming to work in the first place.
You can’t send any emails or reports, and you can’t download anything. With impatient clients ringing everyone’s phone off the hook (because their Internet and emails are down too), you and your coworkers bust out the old dusty fax machines to send and receive documents.
The only problem with that is there aren’t enough fax machines for everybody! That’s when you notice another problem: with the whole world calling each other on their landline phones, they’re overloading communication systems – to the point that you can’t reach anyone.
It’s almost 10am, and everybody’s up by now. With the office becoming more of a circus with every passing minute, the boss decides to let everyone just take the day off. Hopefully, things will be back to normal by tomorrow…
It’s close to 11:15 in the morning. Traffic is still congested, but there’s no point going home and just staring at the wall. So, you walk around until you find a place to grab some lunch. You can’t remember how much money you have in the bank, and there’s no way to check. Both your credit and debit cards are now useless pieces of plastic.

Are all the memories lost?!

So, you take a 10-minute walk to your local branch. On the way, you hear people’s theories on what happened. Some are talking about a global cyber-attack, others are talking about something happening to the satellites. That’s when it hits you: what about all your pictures, videos, and data?
You had your whole graduation video on the cloud. All those pictures of your backpacking trip across Europe? Are all the memories lost? You feel your heart racing. It’s both your fast-pace walking and the thought of losing all those precious records of the best moments of your life…

The social media market is collapsing…

On your way, you stumble across a newsstand. All the papers are nearly gone – you grab the last one. The headline reads: “THE END OF THE INTERNET!” You read briefly that social media companies have already lost billions, and the market is collapsing.

Panic in major cities

You get to the bank at 11:45. …You and everyone else. There’s a line extending outside the entrance. You take your place at the end only to hear the faint sound of the teller announcing, “We’re about to run out of cash, you’ll have to come back tomorrow.”
Luckily, your turn comes right before they start sending people away. You take 400 bucks out of your account to keep yourself afloat. Who knows if it’ll be enough – there’s no way of knowing how long this nightmare will last! As you step outside, someone runs and snatches a guy’s wallet from his hands.
People are already getting desperate, and thieves are taking advantage of the situation. You quickly hide your money in your front pocket. It’s 12:30, so you head out for lunch. Most places have hung handwritten signs on the door: CASH ONLY. Well, good thing you made it to the bank.
You find a diner and notice they’ve got the news on the TV hanging in the corner. There’s no Internet across the ENTIRE globe! Airports are at a standstill, along with ships, trains, and commercial trucking. Panic has broken out in major cities. That’s when you remember your folks should be flying home from their vacation in Ireland!
You try to call them – no answer. You have no idea if their flight was delayed or canceled – how can you get hold of them?! “It’s fine, they’re ok. Hey, who wouldn’t wanna be stranded in beautiful Ireland?” For now, you’ve got other things to worry about.
You need to stock up on food just in case this Internet thing lasts longer than anyone expects…or is ready for… It’s 2pm, and the streets are packed. It looks like everyone else has also taken the day off work. You naturally start heading to the nearest supermarket, but you figure it’ll either be chaotic or just closed since their POS systems need an online connection.
And big places like that aren’t about to bust out the pen and paper to keep track of sales. You ask a passerby if there are any little family-owned stores in the area. You would’ve just googled that before, now you have to talk to someone! You take the woman’s directions and find the place. They don’t have a lot, but you grab whatever you can carry in two hands and head home.

Scary thought

As you walk, you start thinking about how everything you do revolves around the Internet. You scroll for hours through your social media feed, you watch everything on YouTube or streaming services, you have cable TV, but you rarely watch it. You feel so isolated not having heard from any of your friends…

Weird evening

You finally get home at about 4pm. You know it’s a waste of time, but you check the router anyway. Still no Internet. Since you can’t stream anything, you decide to watch good old-fashioned TV channels filled with old movies and shows.
What a feeling! Granted, you won’t be able to google the actors or any spoilers, but that’s the joy of it! The commercial breaks, not so much… At about 6pm, the phone rings, and it’s your parents.
They’d been stuck at the airport all day only to see their flight being delayed further and further until it was finally canceled. They’ve just settled into a hotel for the night with plans of flying out in the morning. But at least they’re ok! And you don’t make it much longer yourself.
After a hectic day, you’re ready for bed. At about 10pm, you fall asleep to the thought that you’ll face the same chaos tomorrow, and you’re already stressed about work. It’s 3:15 in the morning. You wake up to multiple notification sounds on your phone, and as you turn over, your screen is flashing with pop-up boxes left and right. Phones all across the city – across the globe! – are lighting up as if on command.
You take a look and let out a sigh of relief: the world is back online! Phew!

Why Planes Leave Trails in the Sky? 15 Q&A About Airplanes

Why Planes Leave Trails in the Sky? 15 Q&A About Airplanes

Why Planes Leave Trails in the Sky? 15 Q&A About Airplanes

Ok, here’s a little riddle for you they’re long white and you can see them in the sky. what is it I used to think it was old man winter farts. but no. if you answered contrails from a jet then you’re the winner.
But what causes them lets find out. Ever noticed how on a cold day you see your own puff of breath when you exhale the exact same thing happens to a plane. The temperature at 25,000 feet or higher which is cruising altitude is really low around -30 degrees Fahrenheit.
While the engine burns the fuel it releases different substances mostly water and carbon dioxide into the atmosphere. the cold air condenses and sometimes even freezes the hot exhaust fumes creating those whitetails which look a lot like smoke. that’s why they’re often called condensation trails or contrails. To give you an idea, planes like the Boeing 747 eject around 2 gallons of water every 3 seconds. that’s a lot of water to condense.
Ok, but why are these contrails sometimes long and sometimes short well this depends on the weather. Long contrails form in humid conditions while low humidity makes them much shorter and that’s how these white lines can help you predict the weather. If you see long contrails it might mean that a storm is coming.
If a plane leaves short lines then don’t worry: the weather will be good. even though traveling by plane is common nowadays these huge steel birds are still surrounded by secrets and myths that give birth to a lot of questions.

1. Why Can’t Planes Fly when it’s Extremely Hot?

Hot air is less dense than cool air, this means the air molecules are spread further apart from each other so they come into contact with the plane’s wings less. As a result of its harder for a plane to take off. It needs a higher take-off speed which would require a longer runaway. Besides planes rely on different internal machinery and a good part of it already runs hot.
That’s why when the temperature is 120 Fahrenheit or higher the plane might be delayed since the possibility of overheating the electronics is dangerous.

2. Can a Plane Fly on One Engine?

Yes, it can. especially if it has one engine. Haha. Okay even though, thanks to technological improvements engine failures have become pretty rare they still happen sometimes due to damage.
However, losing an engine in-flight isn’t even considered a serious problem by pilots. This is mainly because planes that fly over oceans or for long-distance routes have special certificates that indicate the exact time they can operate safely with one engine. For example, the Boeing 787 can fly around 330 minutes without the second engine.

3. Do Plane Oxygen Masks have Only 15 Minutes of Air?

Yes, they do but that’s enough for an emergency. If the cabin is depressurized at a high altitude the passengers won’t be able to breathe so they use oxygen masks. At the same time, the pilot will start descending right away to get lower than 10,000 feet where its possible to breathe normally again. And this descent won’t take longer than 15 minutes.

4. What Are Those White Spiral Marks On Airplane Engines?

These spirals of different sizes and shapes are for the safety of the ground crew. The ground crew has to wear hearing protection so they can’t hear the roaring engines of a plane. But when they see the spirals swirling they know it’s not safe to approach the area. Also, these spiral marks help to tell which plane is about to take off if there are several of them on the ground.

5. Is there the safest seat on an airplane?

Most airlines claim that the safest seat is just a myth. But statistics of airplane crashes beg to differ. They say that this seat is at the back. If you happen to sit near the tail of a plane you’re about 40% more likely to survive a crash than those in the front. If you need a more specific answer it’s the middle seats in the rear section.

6. Why are their Black Triangles Inside a Plane’s Cabin?

These black stickers are located on about four windows in a cabin. Each of them is aligned with the edge of the wings. If a flight attendant believes there might be something wrong with the moving parts of the wings slats or flats they know exactly which window provides the best view to check them. Also, you should choose a seat between those triangles if you tend to get motion sickness. The plane’s center of gravity is at the wings so you’ll have a smoother trip.

7. Why are Airplane Windows Round?

Actually, at the beginning of the commercial flying era, they were square. But after some time airlines started flying at higher altitudes requiring the cabin to be pressurized. But the frequent pressurization and depressurization caused the window corners to deform and even break.
Turned out that round windows can withstand the pressure of cruising altitude much better. So square windows were soon replaced for good.

8. Why does the Planes Food Taste Bad

Apart from the fact that onboard you’ll get only defrosted dishes which lost a big part of their flavor the pressurization of the cabin is to blame. The air in the cabin might be drier than a desert literally. And this numbs a lot of your taste buds. Besides quite often the cabin air can cause your nasal cavities to swell making the food taste even more unappealing.

9. Is it possible to avoid turbulence

Turbulence is disturbances in airflow. The causes can vary; some by weather conditions some by cumulonimbus clouds which actually are also weather conditions. While it’s impossible for planes to steer clear of turbulence altogether pilots do a lot to lessen it by bypassing areas of heavy turbulence for passenger’s comfort. But if you’re a nervous flyer here’s a tip for you choose morning flights because the air is less bumpy at this time. Do you think flying is scary? let me know in the comments.

10. Why do your Ears Pop During Flying?

Ears pop because there’s a rapid change in pressure. When a plane reaches a cruising altitude or lands, there’s not enough time for the pressure inside the inner ear and the air pressure outside to equalize. And the air trapped inside your inner ear causes the eardrum to pop. If you don’t want ear-popping to turn into pain, try chewing gum or yawing to help your eardrums adjust faster. This is also the reason you’ll sometimes hear babies crying during the descent. They have a hard time equalizing their ears.

11. Are Planes Tray Tables the Dirtiest Things on Board.

Sadly tray table surfaces have eight times more bacteria than the lavatory flush buttons. Unfortunately, quite often cleaning crews don’t have enough time between flights to take care of everything properly. So don’t forget to wipe the tray table down with a sanitizing wipe and don’t let your food sit on it. By the way, seat pockets and seatbelt buckles are almost as dirty.

12. What Citizenship Does a Baby Born Onboard Get?

There are several options. A newborn can become the citizen of the country where the airline is registered; the country over which they were born; or the country where the plane landed. The decision is usually made by the airline depending on the laws of the countries involved. However, the first option is the most common. Sometimes such babies get a bonus from the airline –a free first-class trip to any part of the world on their 18th birthday.

13. Why are Most Planes White?

First, because extra paint would add around 1200 pounds to its weight and the heavier the plane the more fuel it burns. Airlines simply don’t want to pay the extra money. Also, the white color keeps a plane cool by reflecting sunlight. And there are safety reasons: its easier to spot any cracks damage or oil spills on a white surface. Plus in case of a crash, the white fuselage will be able to attract the rescuer's attention faster.

14. Why are there No Parachutes Onboard?

Putting one on and jumping out of the plane correctly is no easy feat. You probably wouldn’t be able to do it in an emergency situation. Training for skydivers requires many hours in which they learn all the details about handling a parachute and how to land safely. What’s more even the most experienced skydivers don’t jump from an altitude higher than 15,000 feet. On top of that adding just parachutes without helmets and supplemental oxygen for all passengers would mean making a plane 8,000 pounds heavier.
