Reference excerpt

Unfavorable Semicircle is a defunct 2015 YouTube channel that garnered attention due to the high volume and unusual nature of the published videos, usually featuring distorted audio and graphics. The channel was suspended in February 2016 shortly after the BBC reported on the channel. Over the years, many theories have been formed about the nature of the project, including that the channel was a numbers station, an alternate reality game, a test channel looking for exploits, or outsider art. In June 2022, an anonymous X user said the channel was an outsider art project.

Origins In March 2015, a YouTube account with the title Unfavorable Semicircle was created; the channel began uploading large numbers of videos on April 5. The channel continued to post large numbers of videos all titled with the Sagittarius symbol or a random six digit number, or both, but most lacking a description. The videos often display abstract, pixelated images. In some cases, they show just a single dot in a field of solid brown. Some videos omit sound while some feature distorted sounds. Some videos are only seconds in length, while others are much longer; ⁠one completely silent video was 11 hours in length.

Attention and disappearance Due to the volume of uploads and the odd nature of the videos, observers started to take notice. Eventually, a small community on Reddit formed to investigate the channel. According to computer security specialist Alan Woodward at University of Surrey, it is probably "too complex" to be a numbers station, and is also unlikely to be a recruitment puzzle as those are usually announced in some way. The BBC has referred to Unfavorable Semicircle as "YouTube's strangest mystery". Unfavorable Semicircle has also been referred to as "one of the Top 10 Weirdest YouTube Channels". In February 2016, several hours after the BBC made an article on the channel, YouTube suspended the channel.

Observations For years, the ♐LOCK and ♐DELOCK videos were seen by some people as the keys to solving the channel's mystery, due to their name and eerie nature.

Reason for creation In a Twitter post, a user claiming to be the creator of Unfavorable Semicircle said that the goal was to "upload the most number of YouTube videos ever" and secondarily "to see if people would watch something truly and unknowable ... My hope was to fill some of the 'Internet Mystery' space left by Webdriver Torso".

Worked examples

Example 1 — a first encounter with Unfavorable Semicircle

Start with the simplest possible case. Write down what Unfavorable Semicircle claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Unfavorable Semicircle before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Unfavorable Semicircle ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Unfavorable Semicircle

In research: Unfavorable Semicircle appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Unfavorable Semicircle in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Unfavorable Semicircle is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of the Internet, Internet mysteries, Puzzles, so understanding it makes those chapters shorter.
In everyday life: Look for Unfavorable Semicircle outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
