Borderline fun

How a pig started a war: 10 of the funniest border disputes ever

Borders are treated seriously—but not always. From prank invasions to livestock wandering into the wrong country, some of history's most absurd geopolitical clashes are downright comedic. While most of these disputes didn’t lead to war, they certainly led to raised eyebrows, diplomatic side-eyes, and in a few cases, friendly resolutions over a shared drink.

France vs. Spain, 1659–present

After the Treaty of the Pyrenees, France and Spain agreed to co-own a small island in the Bidasoa River. But how? By literally swapping custody every six months.

For centuries, Pheasant Island has switched national flags twice a year without issue—despite having no permanent residents.

Canada vs. Denmark, 1984–2022

For nearly 40 years, Canada and Denmark playfully "invaded" Hans Island, which by the way is a completely barren rock islet, by planting flags and leaving bottles of liquor behind.

In 2022, after many years of endless border pranks (and shared liquor), the two countries finally agreed to split the rock 50/50, calling it the "Whisky War" resolution.

USA vs. UK, 1859

It all started when an American farmer shot a British pig rooting in his potato patch on the San Juan Islands. This seemingly minor incident, however, sparked an international crisis that was only narrowly averted after U.S. President James Buchanan himself stepped in.

After this event, troops camped in a peaceful standoff for 12 years until arbitration gave the islands to the U.S. No human lives were lost, but still, sadly, the pig became the sole casualty of the conflict.

Egypt vs. Sudan, 1902–present

Due to conflicting colonial maps, Egypt and Sudan both claim the more valuable Hala'ib Triangle—and disown Bir Tawil, a barren strip of desert.

To this day, Bir Tawil remains one of the few unclaimed territories on Earth. Many micronations and would-be monarchs have planted flags there, but no one officially claims it.

Belgium vs. Germany, 20th century

After Germany’s defeat in the First World War, it was required to cede vast swaths of land to other European nations. Among these was the Vennbahn, an old railway built under the German Empire.

When the Vennbahn railway tracks were transferred to Belgium, a peculiar situation arose: the railway snaked in and out of what was rightfully German territory, creating hundreds of small German exclaves entirely surrounded by Belgian land.

India vs. Bangladesh, 1970–2010

New Moore Island was a small, uninhabited sandbar that unexpectedly emerged from the Bay of Bengal in the 1970s, and both countries claimed it—only for the sea to reclaim it in 2010.

The long-winded dispute disappeared as literally as the island itself, with nature doing the diplomacy by sinking the land back underwater.

Russia vs. China, 2000s

Not exactly a border dispute, but more of an unfulfilled promise and stalled partnership—a massive steel bridge across the Amur River, separating Russia and China, remained unfinished for years, stopping mid-stream due to inactivity on the Russian side.

This created a humorous situation for locals on the Chinese side, who could see that their half of the bridge was completed long ago, yet it led to nowhere. Eventually, Russia completed its half—but only after satellite photos of the disconnected bridge ends went viral.

Australia vs. Rabbits, 1900s

Not a nation-vs-nation conflict, but a border of sorts: Australia once built a 2,000-mile fence to separate rabbit-infested regions from rabbit-free ones.

However, the rabbits won in most cases, either by digging under or jumping over. While the fence failed to completely stop them, it did become a bizarre national landmark.

Imaginary

While there were no actual disputes here, since the territory in question is completely fictional, "Null Island" is a fun example of a made-up place created solely for cartographic purposes.

Located at 0°N, 0°E, this imaginary island is often used humorously in mapping and geographic databases, or as a placeholder for errors—a sort of cartographic joke.

Belgium vs. Prussia, 1816–1919

For almost a century, a small triangle of land with a valuable zinc mine became a "neutral" zone jointly administered by two countries—mainly to circumvent the new border policies established by the 1814 Congress of Vienna.

A flag was even designed, and over time, locals proposed adopting Esperanto as the official language, with some pushing for independence. The League of Nations eventually dissolved the territory, but not before it became Europe’s weirdest almost-country.

Glitches in science

Forget conspiracy theories—these 10 weird facts are real and unexplained

Despite centuries of scientific progress, the universe can still throw us some curveballs that seem to defy all logic and understanding. From bizarre sounds deep in the ocean to strange behavior of stellar objects, these unexplained phenomena continue to stump researchers. Here's a breakdown of 10 strange, real-world mysteries that seem like glitches in reality—and so far remain unsolved.

Discovered in 2017, ‘Oumuamua had an unusual shape and trajectory. As it exited the Sun’s influence, it accelerated slightly—an unexpected behavior that left many scientists puzzled.

Some proposed it was an alien probe or, more likely, that outgassing caused the motion, but no definitive explanation fits all the observed data. For now, the mystery of ʻOumuamua remains unsolved.

Ball lightning has been reported for centuries, often lasting longer than normal lightning and moving erratically indoors or out. Witnesses describe orbs ranging from pea-sized to several feet in diameter.

Even now, there is rare photographic evidence, and the phenomenon has defied controlled reproduction. A 2014 study in China captured spectral data, but scientists still can't agree on how or why it forms.

The 72-second radio burst, detected by Ohio State’s Big Ear radio telescope in 1977, was so unusual that astronomer Jerry Ehman circled it and wrote "Wow!" in the margin.

No known natural or terrestrial source matched its signature. Despite repeated searches in the same spot, the signal has never been heard again.

Captured in 1997 by underwater sensors thousands of kilometers apart, the "Bloop" was an ultra-low-frequency sound louder than any known sea creature. It matched no whale or geological activity profile.

NOAA later suggested icequakes as a possible source, but the exact characteristics didn’t match typical ice calving.

Observed in areas like Japan and Italy, these luminous events precede seismic activity by seconds or minutes. They range from white-blue glows to flame-like columns.

No single mechanism explains them. Theories involve piezoelectric effects in rocks, but reproducible lab evidence is sparse and inconsistent.

Strangely, some organ recipients report new preferences and even memories post-surgery. These aren’t rare coincidences—dozens of documented cases involve patients suddenly acquiring traits of their donors.

A woman who received a heart from a biker craved beer and fast food, which she never had before. A form of cellular memory or nervous system signaling beyond current knowledge has been proposed as a possible explanation, but too little is still known about the phenomenon.

Apparently, hot water can sometimes freeze faster than cold water. Observed since Aristotle and confirmed in many experiments, this phenomenon—known as the Mpemba effect—defies our current understanding of thermodynamics.

While evaporation and convection may play a role, they don’t explain all scenarios. No consistent model accurately predicts when the effect will occur, despite decades of research.

An invisible force is accelerating the universe’s expansion—and we still barely understand it. First inferred from supernova data in 1998, dark energy appears to make up about 68% of the universe’s mass-energy content.

Yet no direct measurement or particle-based theory explains its nature. It’s known only through its large-scale gravitational effects.

Also known as KIC 8462852, Tabby’s Star is a binary star system in the constellation Cygnus, approximately 1,470 light-years from Earth. The star dims erratically—yet in ways that don’t match common explanations like planetary transits.

Its strange behavior has led some astronomers to speculate about exotic causes, including an alien megastructure. However, current data largely rules out that possibility.

Weird as it sounds, a region in East Antarctica has less gravity than expected. While gravity varies slightly across the Earth, the cause of this particular anomaly remains unknown.

Known as the Wilkes Land Mass Anomaly, it covers an area approximately 200 miles wide and causes a noticeable local drop in gravity. First detected via satellite data, it may be the remnant of a massive asteroid impact—or maybe even something deeper.
