A mysterious YouTube video has grabbed the internet's attention. It shows nothing but a pitch-black screen, with no sound and no movement. Yet, according to its timer, it runs for more than 100 years. The video was uploaded earlier this month by an account named @shinywr. Millions have pressed play, puzzled by this silence stretching beyond reason. Viewers quickly saw something strange. The video began as a weird boredom breaker but soon became a viral puzzle. Tech experts, conspiracy theorists, and everyday users joined the discussion. Speculation flooded social media. One user on X said, "That’s bizarre, and it makes you wonder whether it’s a glitch, an experiment with the platform’s limits, or some kind of digital time capsule." However, YouTube's video length limit raised questions. Verified users can upload videos only up to 12 hours. This made many doubt the century-long runtime. A technical explanation followed: "That video actually 12 hours 30 minutes 56 seconds. YouTube stores video duration as a number in milliseconds. If the uploader, encoder, or streaming manifest feeds YouTube a broken or deliberately overflowed value, the UI converts garbage math into absurd numbers like decades or centuries," explained one commentator. Not everyone sees this as a glitch. Some users joked about it. Comments like "this is DEFINITELY the start of a conspiracy theory ppl are randomly gonna talk about 10 years later or something 😭😭" and "This is gonna have some insane lore in 10 years😭🥀🥀" filled the chat. Further digging added more mystery. The channel says it operates from North Korea, where YouTube is blocked. It also hosts another oddly named video suggesting hundreds of hours, yet that one is just over 12 hours. Interestingly, the uploader wrote, "why are my videos getting recommended to people? this channel was supposed to be a secret." Whether this is a glitch or a clever experiment, this silent video shows how mystery can roar loudest in the digital world.
