For cocoa may be the most closely guarded secret in the history of american commerce.

Welcome to watch mojo.

And today we're counting down our picks for the top 10 world secrets that will never be revealed.

Now that secrecy is a bit of a problem for this list.

We're looking at various well kept secrets from around the world that will likely never be fully revealed to the public or will never be uncovered whatsoever.

Which of these are you most curious about let us know in the comments below number 10 Letters of Last Resort.

This is the stuff that spy movies are made of belonging to the United Kingdom.

The letters of Last Resort are exclusively written by the newly appointed prime minister.

Four different letters are penned which are then given to four submarines equipped with destructive trident missiles.

Within the letters are instructions telling the commanding officers what to do in the event of a nuclear strike on Britain.

No one but the prime minister knows the exact contents of the letters as they're kept sealed until nuclear war breaks out in the event that nuclear war doesn't break out, which thankfully it hasn't.

The letters are destroyed upon the inauguration of a new P.

M.

Number nine.

The imperial napkin fold.

It's hard to imagine a simple napkin being the subject of a state secret.

But such is the magic of the imperial napkin fold the napkins at Austrian governmental events are given the fancy fold, which results in a gorgeous flourish, befitting the rich dignitaries who attend these types of events.

Also known as the Hapsburg napkin fold.

The technique is a guarded state secret and it's said that only two people at a time know how to do it.

They then passed the knowledge on to another high ranking official upon their deaths napkins folded in this manner are even kept in Austrian museums, public interest in their extravagance being so profound.

Number eight, the coca cola recipe coca cola has been around since 18 86 and try as desperately as they might.

No one has been able to replicate its distinct taste.

That's how you know, you have a good beverage on your hands.

The people who handle the concentrate r as in the dark about the secret formula as anyone inventor john s pemberton kept his recipe a secret and even refused to write it down for fear of people copying his success.

It was finally jotted down when Ernest Woodruff purchased the company in 1919.

The first recipe called for cocaine, but over time the narcotic ingredient was removed but not the secrecy.

The physical recipe then made the rounds between new york's guaranteed bank, Atlantis trust company bank and finally, the world of coca cola, which is where it resides today.

It is currently housed in the so called vault of the secret formula and it remains a very closely guarded trade secret once a year.

Somebody show up and say I have the original formula for coca cola.

How much will you pay me for?

Well, we don't need to pay them anything for because we have the only real one.

Number seven the origins of HIV AIDS Sanders has feared this unknown unnamed disease so much they wouldn't even go near someone with AIDS.

The fear was pervasive.

While HIV is largely linked to the 19 eighties, it continues to be a problem.

In 2020 alone it was estimated that nearly four million people were living with the disease, 70% live in sub Saharan africa.

But anti retroviral drugs offer hope new infections are down by over a third mother to child transmission has more than halved and globally has been a 35% decrease in deaths.

But regardless of its prevalence and very public history, there is still a lot about the retrovirus.

We don't know even those of us who were in it from day one were shocked by the enormity of the problem.

For example, humanity is still mostly unsure of where it came from.

The leading theory is that african hunters in the early 20th century killed and ate chimpanzees infected with S.

I.

V.

The S.

Standing for simeon, which then mutated into HIV in the human body.

However, this information is typically populated with words like probably and likely indicating that the origins of HIV are now not definitively known even to this day.

Number six.

The farmer's almanac formula, wow, listen to this, we are in for a brutal winner.

That's according to the farmer's almanac.

Farmer's almanac has been annually published since 18 18.

So it's obviously doing something right.

The almanac makes long term weather predictions in north America and various scientific studies have proven a roughly 50% rate of accuracy.

So basically take this with a grain of salt.

Not bad, considering the predictions come up to two years in advance and it seems like the local weather station doesn't even know if it will rain tomorrow.

And according to their website, they use an exclusive mathematical and astronomical formula that relies on sunspot activity, title action, planetary position and many other factors.

Weirdly almost nothing is known about the making of the almanac.

The forecaster is kept secret and the almanac itself has never revealed how it makes its predictions.

The formula is reportedly kept inside an Impenetrable box and the world is left wondering just how the heck these gods can so accurately predict the weather.

It's kind of like the coca cola recipe number five Genghis khan's tomb living in the mid 12th century to the early 13th, Genghis Khan is the infamous instigator of the Mongol empire, which was the largest connective empire in history.

He rose from abject poverty to rule most of the known world.

It is claimed that one in every 200 men alive today is descended from him after taking over much of the known World.

Khan died under unknown circumstances and was returned to his home country of Mongolia legend has it that the funeral procession killed anyone who witnessed it in order to keep his final resting place a secret.

If that's true, it certainly worked because no one today has any idea of where Genghis khan is buried.

The Mongolian belief is that if you disturb the tomb of Genghis khan, the reason why that area was so forbidden is because if you disturb this tomb that you might cause this curse will end the world.

Modern scholars believe his tomb is somewhere around the Bergen Haldun mountain, but research in the area is difficult owing to restrictions imposed by the Mongolian government.

Finding the two of Genghis Khan would be the greatest archaeological discoveries of our generation.

The potential for riches in Genghis Khan's tomb are extraordinary.

You think of it as the world's largest land empire, the riches that must have been plundered and the riches that might be inside this tomb, boggle the mind number four, the lost years of jesus christ.

Many scholars and historians agree that Jesus christ was a real person and that he was born sometime around four Bc.

However, a large chunk of his historical life remains unaccounted for as no one knows what he was doing between the ages of 12 and 29 during all this time.

There is but one story in the gospels, it describes Jesus as a precocious 12 year old discussing the hebrew bible with rabbis in Jerusalem.

These are referred to by a variety of names, including his silent years.

Of course there are many theories, some believe he was in Britain.

Others India.

There are said to be records originally written in India in the ancient pali language and later translated into Tibetan dealing with the life of an extraordinary saint.

Known to the Buddhists as esa.

The life story of ST esa closely resembles the life of jesus christ.

But the leading theory is that he was in galilee, a region of both Israel and Lebanon working as a carpenter under the tutelage of his father, joseph once in the new testament in the gospel of Mark jesus critics in his hometown.

Ask is not this the carpenter.

And then in the parallel text in Matthew, they ask, is not this the carpenter's son following jesus unknown excursions.

He was baptized in al Maqdis around 28 A.

D.

And it is here that his world changing ministry began.

Number three.

The USa is missile submarines.

There's something about submarines and secrecy.

The United States owns various missile submarines that are guided by nuclear power including the USs Ohio michigan florida and Georgia still very secret.

Well guarded.

It's dark and it's massive.

It's as long as the Washington monument is high, nearly the length of two football fields.

The sale as it's called stretches high into the air.

These are known as S.

S.

G.

N.

The missiles on board.

These subs have the potential to cause great destruction but there were whereabouts and activities are generally unknown.

Unlike a surface ship that someone can see or a satellite.

They however they literally surfaced from time to time.

For example michigan appeared in south Korea in 2017.

In florida took part in operation odyssey dawn in Libya.

During the Cold War.

The USs florida prowled the oceans equipped with trident nuclear missiles ready to carry out and attack.

At a moment's notice.

On june 28th 2010 a rare event occurred which saw three of four surfacing at once in response to chinese missile tests.

These four subs have been SGN since the two thousands but most of their actions and locations have remained a secret.

We won't go any further but you're literally standing 10 to 20 ft from an operational nuclear reactor right now.

Number two, the mausoleum of the first Chin emperor.

Look at the scale of this place tells you a lot about the guy, his ego, his vision for his afterlife.

What an experience!

It's amazing how little we know about a unesco world heritage site found in China's Shanxi province is this world renowned mausoleum which is most famous for its terracotta army.

It took 700,000 laborers and 40 years to build constructed from 2 46 to 208 B.

C.

The area houses approximately 8000 terracotta soldiers and the tomb of qin shi huang row upon row of warriors, hundreds of secret subterranean soldiers.

All life sized and built to be immortal.

This is a massive underground necropolis containing, well, no one really knows.

The burial tomb itself still hasn't been excavated.

But Han dynasty historian Sima Asean states that it contains quote fine vessels, precious stones and rarities.

But like many archaeological discoveries, it has probably been long looted.

Perhaps we'll never know what it truly looks like within the mausoleum complex.

Number one.

Area 51.

Take my word for it.

There's no Area 51.

There's no recovered spaceship.

Excuse me.

Mr.

President.

That's not entirely accurate when it comes to highly classified areas.

It doesn't get more famous than Area 51 found in the Nevada desert.

Area 51 is a top secret military facility with ties to cutting edge technology.

The military base, 80 miles from las Vegas has become infamous for conspiracy theories about little green men.

They certainly appear to still be covering up what exactly goes on at Area 51.

The place is so secretive that it wasn't officially unveiled by the CIA until 2013.

Even though it was very obvious that something was in the desert.

Area 51 is officially known as a military training facility and supposedly a testing ground for both experimental aircraft and high tech weaponry.

The area 51 designation is said to come from Atomic Energy Commission designation maps in the 1930s it was a wildlife reservation under the Department of the Interior, but the War Department then took it over in 1942 during World War II.

Owing to its secretive nature, both trespassing and flying over the site are grossly prohibited and dangerously enforced naturally.

This has given rise to a swath of conspiracy theories.

Are aliens inside area 51 perhaps we'll never know.

But because of all this secrecy see many made up their own minds a long time ago about Area 51 that's why it may never lose its extraterrestrial excitement.

Do you agree with our picks?
