Seven years ago, social media users famously couldn't decide whether a dress was blue or gold. Now, there's a new debate taking over social media that likely won't be settled anytime soon. Twitter user Ryan Nixon started a poll on the platform around a question he was considering with friends: are there more doors, or wheels, in existence? "My mates and I are having the STUPIDEST debate...And I am here for it," Nixon tweeted. "Do you think there are more doors or wheels in the world?" The tweet quickly went viral, with hundreds of thousands of Twitter users responding to the poll – and users also debated the question themselves. "Surely doors. Every house has at least five doors on average and there are 2.5 billion houses in the world. Not to mention garages and sheds," one user tweeted. "I also can't believe I spent two minutes of my life wrapping my brain around this." The debate also spilled over to TikTok, where the #wheelsvsdoors page has racked up nearly 17 million views so far. But other users took the debate a step further, and began asking deeper questions, such as what, exactly, counts as a door? "Are valves doors? Are lids? Is a soda pop cap a door or a wheel?" Twitter user asked. In the end, though, Twitter settled on an answer: with a final tally of 223,347 votes, over 53 per cent of Nixon's pollsters said there were more wheels than doors on Earth.
