ONE WILD WORLD — NEWSLETTER

Issue #026   ·   Did You Know?   ·   May 2026

Here is the trouble with general knowledge. Most of what you carry around as “true” is actually a slightly mangled rumour, repeated often enough that it set like cement. Below: five real things that sound like lies — checked, sourced, and offered without warning. Once you’ve seen them, they don’t go back.

On the morning of 27 August 1896, the British Royal Navy and the Sultanate of Zanzibar went to war. The fighting started at about 9.02 a.m. By 9.40 a.m. it was over. Most sources call it 38 minutes; the most generous estimate stretches it to 45. Either way, it stands as the shortest officially recognised war in recorded history.

The cause: Zanzibar’s pro-British Sultan had died suddenly two days earlier, and his cousin, Khalid bin Barghash, had walked into the palace and declared himself the new ruler — without British approval, which by treaty he needed. Britain told him to leave the palace by 9 a.m. on the 27th. He refused. Two minutes after the deadline, five British warships opened fire.

Inside the palace, around 500 Zanzibari soldiers and civilians were killed or wounded. On the British side, one sailor was injured. The Sultan-for-three-days slipped out a side door and into the German consulate, where he sat out the next several years under awkwardly polite diplomatic asylum. He was eventually captured by the British in 1916 — twenty years after losing a war that had taken less time than most football matches.

When you picture “ancient civilisations” and “old universities,” your brain probably sorts them by vibe. The Aztecs feel properly ancient — stone pyramids, feathered headdresses, blood-soaked altars. Oxford feels old, but in a sherry-and-quadrangle sort of way. So here is the order your brain almost certainly has wrong.

Teaching at Oxford was already happening by 1096. It grew rapidly after 1167, when Henry II banned English students from going to the University of Paris and they had to find somewhere closer to home. By 1249 it was a fully recognisable university, with student housing at three founding colleges: University, Balliol, and Merton.

The Aztecs, meanwhile, were still a wandering tribe. Their capital, Tenochtitlán — the city on Lake Texcoco that would become the heart of the empire — was not founded until 1325. The Aztec Empire itself, the Triple Alliance of Tenochtitlán, Texcoco and Tlacopan, did not form until 1428.

By the time the Aztecs laid their first stones at Tenochtitlán, Oxford had been teaching students for 229 years. By the time the Aztec Empire was officially founded, that number was 332. And by the time Cortés rolled in and the empire ended in 1521, Oxford was a 425-year-old institution, still arguing about Aristotle. History is not a tidy queue. It is a room full of people who somehow all arrived at the same party from completely different decades.

The short Napoleon is one of the most successful smears in modern history. The man has been a punchline for two centuries — there is an entire piece of pop-psychology, the “Napoleon complex,” named after his supposed shortness — and the whole thing rests on a unit conversion that nobody bothered to do correctly.

Napoleon’s autopsy in 1821 recorded his height as 5 pieds 2 pouces. In modern English: five feet, two inches. Tiny. Except a French pied was not an English foot. The pre-metric French pouce — “inch” — was 2.71 centimetres; the English inch is 2.54. Convert his measurement honestly and Napoleon comes out at roughly 1.68 to 1.70 metres — between 5 feet 6 and 5 feet 7. For a French man in the early 1800s, when average male height was about 5 feet 5, that made him completely ordinary.

So why does everyone still think he was small? Three reasons. The unit confusion never got widely corrected. The British satirical press — most famously the cartoonist James Gillray — gleefully drew Napoleon as a tiny ranting toddler at every opportunity, and those cartoons travelled. And Napoleon habitually surrounded himself with his Imperial Guard, an elite unit recruited specifically for size. Stand next to a wall of seven-footers in tall hats and even a perfectly average man will look like a sketch of a boiled egg. The man was average. The cartoons were everywhere. Average lost.

In November 2026 — quite soon, as you read this — NASA’s Voyager 1 will become the first human-built object ever to sit one full light-day from Earth.

Let that phrase land properly. The signal Voyager sends home travels at the speed of light, the universe’s hard ceiling. By this November, that signal will take a full 24 hours to arrive. Send a command on Monday morning, get a “received” back on Wednesday morning. The probe is currently around 25.8 billion kilometres away, drifting through interstellar space at about 61,000 km/h, and increasing the distance every second.

It is talking to us, somehow, on a radio transmitter that puts out about 22 watts. That is less power than the bulb in most people’s hallway lamps. By the time the signal reaches Earth, after crossing roughly 16 billion miles of empty space, it has been spread so thin that it arrives at less than an attowatt — a billionth of a billionth of a watt. NASA pulls it out of the noise using 70-metre dishes and several decades of accumulated cleverness.

Voyager 1 launched on 5 September 1977, on a mission originally scheduled to last four years. The plutonium powering it loses about four watts of output every year, and at this point seven of its ten original instruments have been switched off to save energy. Engineers think it will keep talking until roughly the early 2030s, after which it will go silent and just keep going — for the next several thousand years, at minimum, sailing through interstellar space carrying a gold-plated record of greetings, music, and the sound of a human kiss, in case anyone out there ever finds it.

The quietest place on Earth is a small chamber inside Microsoft’s headquarters in Redmond, Washington. It measures somewhere around minus twenty decibels. Human hearing starts at zero. Below that, sound is, in any meaningful sense, gone.

Inside, your ears do not rest. They get to work. Stripped of all external noise, they start picking up your own body. You hear your heartbeat. You hear blood moving through your vessels. You hear your lungs filling and emptying. You hear your stomach gurgling. Move your head and your neck makes a faint grinding sound you have never noticed before. As Steven Orfield, who runs the world’s second-quietest chamber, has put it — inside the room, you become the sound.

This is when things get strange. With no ambient sound, your brain loses one of the cues it uses to figure out where you are in space. After about half an hour, most people cannot stand without a chair, because their sense of balance has quietly fallen apart. Visitors report disorientation. Some report mild hallucinations. The longest anyone has voluntarily stayed inside such a chamber is around 45 to 55 minutes — and most people leave a long time before that, often shaken.

NASA uses anechoic chambers like this one to train astronauts. The silence of deep space, as it turns out, is one of the more psychologically disturbing things a human being can experience — and the agency would rather you fall apart in Redmond than in orbit.

A war that ended in less time than a meeting. A university older than an empire. A short man who was not. A signal so faint it is barely a photon. A silence that breaks the people who walk into it.

The world is mostly a rough sketch. Every so often a fact comes along and quietly redraws it — and the new shape, every single time, is stranger than the one you were carrying around.
