Most of us still call them UFOs – unidentified flying objects. NASA recently adopted the term “unidentified anomalous phenomena,” or UAP. Either way, every few years popular claims resurface that these things are not of our world, or that the U.S. government has some stored away.

I’m a sociologist who focuses on the interplay between individuals and groups, especially concerning shared beliefs and misconceptions. As for why UFOs and their alleged occupants enthrall the public, I’ve found that normal human perceptual and social processes explain UFO buzz as much as anything up in the sky.

Historical context

Like political scandals and high-waisted jeans, UFOs trend in and out of collective awareness but never fully disappear. Thirty years of polling find that 25%-50% of surveyed Americans believe at least some UFOs are alien spacecraft. Today in the U.S., over 100 million adults think our galactic neighbors pay us visits.

It wasn’t always so. Linking objects in the sky with visiting extraterrestrials has risen in popularity only in the past 75 years. Some of this is probably market-driven. Early UFO stories boosted newspaper and magazine sales, and today they are reliable clickbait online.

In 1980, a popular book called “The Roswell Incident” by Charles Berlitz and William L. Moore described an alleged flying saucer crash and government cover-up 33 years prior near Roswell, New Mexico. The only evidence ever to emerge from this story was a small string of downed weather balloons. Nevertheless, the book coincided with a resurgence of interest in UFOs. From there, a steady stream of UFO-themed TV shows, films, and pseudo-documentaries has fueled public interest. Perhaps inevitably, conspiracy theories about government cover-ups have risen in parallel.

Some UFO cases inevitably remain unresolved. But despite the growing interest, multiple investigations have found no evidence that UFOs are of extraterrestrial origin – other than the occasional meteor or misidentification of Venus.

But the U.S. Navy’s 2017 Gimbal video continues to appear in the media. It shows strange objects filmed by fighter jets, often interpreted as evidence of alien spacecraft. And in June 2023, an otherwise credible Air Force veteran and former intelligence officer made the stunning claim that the U.S. government is storing numerous downed alien spacecraft and their dead occupants. https://www.youtube.com/embed/2TumprpOwHY?wmode=transparent&start=0 UFO videos released by the U.S. Navy, often taken as evidence of alien spaceships.

Human factors contributing to UFO beliefs

Only a small percentage of UFO believers are eyewitnesses. The rest base their opinions on eerie images and videos strewn across both social media and traditional mass media. There are astronomical and biological reasons to be skeptical of UFO claims. But less often discussed are the psychological and social factors that bring them to the popular forefront.

Many people would love to know whether or not we’re alone in the universe. But so far, the evidence on UFO origins is ambiguous at best. Being averse to ambiguity, people want answers. However, being highly motivated to find those answers can bias judgments. People are more likely to accept weak evidence or fall prey to optical illusions if they support preexisting beliefs.

For example, in the 2017 Navy video, the UFO appears as a cylindrical aircraft moving rapidly over the background, rotating and darting in a manner unlike any terrestrial machine. Science writer Mick West’s analysis challenged this interpretation using data displayed on the tracking screen and some basic geometry. He explained how the movements attributed to the blurry UFO are an illusion. They stem from the plane’s trajectory relative to the object, the quick adjustments of the belly-mounted camera, and misperceptions based on our tendency to assume cameras and backgrounds are stationary.

West found the UFO’s flight characteristics were more like a bird’s or a weather balloon’s than an acrobatic interstellar spacecraft. But the illusion is compelling, especially with the Navy’s still deeming the object unidentified.

West also addressed the former intelligence officer’s claim that the U.S. government possesses crashed UFOs and dead aliens. He emphasized caution, given the whistleblower’s only evidence was that people he trusted told him they’d seen the alien artifacts. West noted we’ve heard this sort of thing before, along with promises that the proof will soon be revealed. But it never comes.

Anyone, including pilots and intelligence officers, can be socially influenced to see things that aren’t there. Research shows that hearing from others who claim to have seen something extraordinary is enough to induce similar judgments. The effect is heightened when the influencers are numerous or higher in status. Even recognized experts aren’t immune from misjudging unfamiliar images obtained under unusual conditions.

Group factors contributing to UFO beliefs

“Pics or it didn’t happen” is a popular expression on social media. True to form, users are posting countless shaky images and videos of UFOs. Usually they’re nondescript lights in the sky captured on cellphone cameras. But they can go viral on social media and reach millions of users. With no higher authority or organization propelling the content, social scientists call this a bottom-up social diffusion process.

In contrast, top-down diffusion occurs when information emanates from centralized agents or organizations. In the case of UFOs, sources have included social institutions like the military, individuals with large public platforms like U.S. senators, and major media outlets like CBS.

Amateur organizations also promote active personal involvement for many thousands of members, the Mutual UFO Network being among the oldest and largest. But as Sharon A. Hill points out in her book “Scientifical Americans,” these groups apply questionable standards, spread misinformation and garner little respect within mainstream scientific communities.

Top-down and bottom-up diffusion processes can combine into self-reinforcing loops. Mass media spreads UFO content and piques worldwide interest in UFOs. More people aim their cameras at the skies, creating more opportunities to capture and share odd-looking content. Poorly documented UFO pics and videos spread on social media, leading media outlets to grab and republish the most intriguing. Whistleblowers emerge periodically, fanning the flames with claims of secret evidence.

Despite the hoopla, nothing ever comes of it.

For a scientist familiar with the issues, skepticism that UFOs carry alien beings is wholly separate from the prospect of intelligent life elsewhere in the universe. Scientists engaged in the search for extraterrestrial intelligence have a number of ongoing research projects designed to detect signs of extraterrestrial life. If intelligent life is out there, they’ll likely be the first to know.

As astronomer Carl Sagan wrote, “The universe is a pretty big place. If it’s just us, seems like an awful waste of space.”

How Water Towers Work

Water towers are one of the most recognizable pieces of infrastructure across the United States. Rising above towns, suburbs, and cities, these elevated tanks quietly perform a vital function every day: maintaining water pressure and storing emergency water for local communities.

Although they may look simple, water towers are an essential part of modern municipal water systems and remain one of the most reliable ways to deliver water to homes and businesses.

The Basic Science Behind Water Towers

Water towers work using a simple principle of physics: gravity.

Water from treatment plants or underground wells is pumped into a storage tank located high above the ground—typically between 100 and 200 feet tall. Because the tank is elevated, gravity naturally pushes the water downward through the city’s pipeline network.

This gravitational force creates the water pressure needed to supply homes, businesses, irrigation systems, and fire hydrants throughout the community.

Most residential plumbing systems in the United States operate best at 40 to 60 PSI (pounds per square inch), which water towers can easily provide through elevation alone.

Why Water Towers Are Built So Tall

The height of a water tower determines how much pressure it can create. Engineers use a common rule:

For example, a water tower standing 120 feet tall can generate roughly 50 PSI of pressure—perfect for delivering water throughout a residential neighborhood.

Why Cities Still Use Water Towers

While modern pumping systems could theoretically move water through pipes continuously, water towers provide several major advantages that make them a preferred design in many municipal systems.

• Stable Water Pressure – Water towers maintain consistent pressure even during peak usage times.
• Energy Efficiency – Pumps can refill towers overnight when electricity demand is lower.
• Emergency Water Supply – If power fails, gravity can continue delivering water.
• Fire Protection – Fire hydrants depend on strong, immediate water pressure.

The Daily Fill-and-Use Cycle

Water towers typically operate on a daily cycle based on community demand.

• Night: Pumps refill the tower while water demand is low.
• Morning: Water levels drop as residents shower and prepare for the day.
• Daytime: Businesses and homes continue drawing water from the tower.
• Evening: The system begins refilling the tank for the next day.

How Much Water Can a Tower Store?

Water towers come in many sizes depending on the population they serve.

• Small towns: 50,000–300,000 gallons
• Suburban communities: 500,000–1 million gallons
• Larger urban systems: up to 2 million gallons or more

Even a single tower holding one million gallons can supply thousands of homes for several hours during peak demand or emergencies.

Modern Technology Inside Water Towers

Today’s water towers are equipped with advanced monitoring systems that help utilities maintain safe and reliable water supplies.

• Automated pump controls
• Water quality monitoring
• Protective interior coatings
• Regular inspections and maintenance

Landmarks in the American Skyline

Many cities turn their water towers into local landmarks by painting them with city names, mascots, or community slogans. Some towns even design towers shaped like giant objects such as fruit, coffee cups, or sports balls.

Despite their distinctive appearance, water towers remain one of the simplest and most reliable engineering solutions for delivering clean water to millions of Americans every day.

Next time you see a water tower rising above a town skyline, remember: it’s not just a landmark—it’s the gravity-powered system that keeps water flowing.

In the vast digital landscape of the internet, strange phenomena occasionally emerge that leave investigators, tech enthusiasts, and everyday viewers scratching their heads. One of the most puzzling cases appeared in 2015, when a mysterious YouTube channel called Unfavorable Semicircle began uploading an astonishing number of cryptic videos.

Within months, the channel had published tens of thousands of bizarre clips, many of which seemed random, incomprehensible, and visually chaotic. But as internet detectives began analyzing the content more closely, they discovered that these videos might not have been random at all.

The Sudden Appearance of an Internet Mystery

The Unfavorable Semicircle channel reportedly appeared in March 2015, with its first uploads arriving in early April.

Almost immediately, the channel began publishing videos at an incredible pace. Observers estimated that the account uploaded thousands of videos per week, sometimes multiple videos per minute. By the time the channel disappeared in early 2016, researchers believed it had uploaded well over 70,000 videos, possibly far more.

The scale alone made the project seem impossible for a human to manage manually.

Strange Visuals and Cryptic Titles

Most of the videos shared similar characteristics:

• Extremely short or very long runtime
• Abstract visuals such as flashing colors, static, or distorted imagery
• Little or no audio, or heavily distorted sounds
• Titles made of random characters, symbols, or numbers

To casual viewers, the videos looked like pure digital noise. However, online investigators suspected something more deliberate was happening.

Hidden Images Discovered

The mystery deepened when researchers began extracting individual frames from some videos.

When thousands of frames from certain clips were stitched together, the results sometimes formed coherent images. One of the most famous examples involved a video titled “LOCK.” While the footage appeared chaotic at first, combining the frames revealed a recognizable composite image.

This discovery suggested the videos were carefully constructed rather than random uploads.

Theories About the Channel’s Purpose

Because the creator never explained the project, several theories emerged across Reddit, YouTube, and internet forums.

Automated Experiment
Many believe the channel was created using automated software that generated and uploaded content at scale.

Alternate Reality Game (ARG)
Some viewers suspected the channel might be part of a hidden puzzle or digital scavenger hunt.

Encrypted Communication
Others compared the channel to Cold War “numbers stations,” suggesting the videos could contain coded messages.

Digital Art Project
Another theory suggests the channel was an experimental art project exploring algorithms, data, and visual noise.

Despite years of investigation, no single explanation has been confirmed.

Why the Channel Disappeared

In February 2016, YouTube removed the channel, reportedly due to spam or automated activity violations.

By that time, the channel had already become a minor internet legend. Fortunately, some researchers managed to archive a large portion of the videos before they disappeared.

Even today, archived clips continue to circulate online as investigators attempt to decode them.

Other Mysterious YouTube Channels

The Unfavorable Semicircle mystery is not the only strange case on YouTube.

One well-known example is Webdriver Torso, a channel that uploaded hundreds of thousands of videos showing red and blue rectangles with simple beeping sounds. Internet speculation ran wild before Google eventually confirmed it was an internal YouTube testing account.

Another example is AETBX, which posts distorted visuals and unusual audio that some viewers believe contain hidden patterns or encoded information.

These cases highlight how automation, experimentation, and creativity can sometimes blur the line between technology and mystery.

A Digital Mystery That Remains Unsolved

Nearly a decade later, the true purpose behind Unfavorable Semicircle remains unknown.

Was it a sophisticated experiment? A piece of algorithmic art? Or simply an automated test that accidentally captured the internet’s imagination?

Whatever the explanation, the channel stands as a reminder that even in a world filled with billions of videos and endless information, the internet can still produce mysteries that challenge our understanding of technology.

Why Internet Mysteries Still Fascinate Us

Stories like Unfavorable Semicircle capture attention because they combine technology, creativity, and the unknown. They invite people from around the world to collaborate, analyze patterns, and search for meaning hidden in the noise.

And sometimes, the most intriguing part of the mystery is that the answer may never fully be known.
