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.

Deep roots

11 everyday words with indigenous roots

English is a very welcoming language in the sense that it incorporates terms from many other languages from all over the world. And, as it couldn’t be otherwise, Native American languages have lent many of their words and terms to English speakers. Some traveled through Spanish or French before settling into English, and others arrived directly through early contact and trade, helping shape the way we speak today. Did you know about these 11 terms?

The word "canoe" comes from the Taino term canoa, which was first used by Caribbean islanders long before Europeans arrived. Early explorers adopted it to describe the slim, sturdy boats they saw.

Over time, "canoe" became the standard English word for a small paddled craft. Today it still carries that sense of simplicity and closeness to nature.

The word "barbecue" comes from barbacoa, another Taino term for a wooden frame used for cooking meat over fire. Europeans adopted it and applied it to both the method and the gathering itself.

Today, "barbecue" means everything from a backyard cookout to a regional cooking style. Its origins highlight the deep culinary influence of Native Americans in the nation's current culture.

"Skunk" comes from the Algonquian word squnk, which means "urinating fox" (quite a fitting term, indeed). This was an obvious reference to the animal’s strong defensive spray. Early settlers adopted the term directly.

Since English had no better name for the creature, the Native word stuck. Today, the word skunks is also used as playful slang.

The word "moose" originates from Eastern Abenaki, a part of the Algonquian family, where it meant "he strips off bark." Yes, it described the animal’s habit of tearing bark from trees.

The name entered English quickly because settlers relied on Native knowledge of local fauna. The word remains unchanged because of its accuracy and usefulness.

"Raccoon" comes from the Powhatan word arakun, meaning "he scratches with his hands." It described the animal’s clever, humanlike front paws.

Settlers adopted the term because it captured the creature’s behavior beautifully. Today, the raccoon is used as a household symbol of curiosity, not unlike the animal itself.

The term "chipmunk" most probably comes from the Ojibwe word ajidamoo, which means "one who descends trees headfirst." Early English settlers adapted the sound into today’s form.

Though the spelling changed over time, the lively image of a chipmunk racing down a tree face-first stayed.

The word "caribou" comes from the Mi’kmaq term qalipu, which means "snow shoveler," referring to the animal’s habit of digging through snow for food.

French settlers brought the word into English, keeping its descriptive nature. The name still connects the modern animal to the winter landscapes it belongs to.

"Totem" comes from the Ojibwe word ototeman, which means "kinship group." It described symbols representing clans and shared roots.

English adopted it to describe carved poles and symbolic elements. Though broader in modern usage, it still hints at the original sense of community, identity, and heritage.

"Coyote" comes from the Nahuatl word coyōtl, which was used by Indigenous tribes of central Mexico. Spanish speakers adopted it, and English borrowed later.

The word kept its meaning, and it remains one of the most direct links between the English language and Nahuatl.

The tasty avocado’s name traces to the Nahuatl word ahacatl, which refers to the fruit and to a body part as well. Spanish speakers transformed it into aguacate.

Later on, English speakers adapted it to avocado. While the name sounds contemporary and culinary, it has ancient Native roots.

The last Nahuatl word and also the last word on the list comes from the term xocolātl, which describes a bitter cacao drink that was consumed long before Europeans arrived in America. The name traveled from Spanish to English.

Though the product changed dramatically, the word survived. Today, chocolate is a universal symbol of sweetness, with rich and deeply indigenous roots.
