Fans have put on their tinfoil hats as a new mystery surrounds one of the world’s biggest festivals. This morning, all of Tomorrowland‘s social media accounts went dark. They changed their profile pictures to nothing but a solid black image and shared the image in posts on each platform as well. 

In addition to the social media accounts, the official website dedicated to the Belgian festival was replaced by nothing but a black screen. Expert-level sleuths from the /r/Tomorrowland subreddit discovered that when you look at the website’s source code (press CTRL-Shift-I or right-click on the page then select “Inspect”) you can see a hidden message that says: “Light travels faster than sound – 299 792 458 m/s.”

Some fans have begun to speculate that the hint means that next year’s theme will be “Pyramids from Space” as it’s been reported that one of the books from the main stage production at the last event had that title. Interestingly enough, the theory is fueled even further considering the Great Pyramid of Giza is oftentimes associated with the speed of light due to the coordinates being extremely close to the speed in meters per second.

At the time of writing, there is no word on whether or not the social media and website blackout is related to next year’s theme announcement.
