Are there more wheels or doors in the world? Internet's latest debate leaves people divided.

Every couple of years or so, people engage in an online "this versus that" debate that relentlessly divides them. Seven years ago, it was the dress that was either black and blue or white and gold—I still don't know. In 2018, the "Laurel" or "Yanny" audio clip tore through social media leaving people arguing over how anyone who heard anything other than the name they heard needed to get their ears checked. Now, there's a new debate on social media and it doesn't seem like this one will be settled any time soon.

It all started last week when Twitter user Ryan Nixon started a poll on the platform around a question he was discussing 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. Do you think there are more doors or wheels in the world?" Nixon tweeted, sharing a poll that over 223k people have responded to. "Who is voting doors??? There's wheels on everything. I have wheels on my garment rack, makeup storage holder, rubbish bin. It’s definitely wheels," wrote @lilyffranklin13.

"In my household, there are 29 doors (including fridge, cupboards, washing machine, tumble dryer and car). Got 4 wheels on my car and the hamster has a wheel, can't think of any more wheels I'm saying doors," argued @MatthewDaubney. "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. I also can't believe I spent two minutes of my life wrapping my brain around this," tweeted @thenzmajority. "Quite the debate at HQ today. My heart says doors. Or wheels. But mostly doors," commented @ClairePierceCCN.

"Obviously doors, right? Most vehicles will have a roughly similar number of wheels to doors, bikes and some lorries notwithstanding. But in my experience, buildings usually have many more doors than wheels," tweeted @Ash_Dunne. The debate also spilled over to TikTok, where the #wheelsvsdoors page has racked up more than 33 million views so far. "What about cruise ships? They don't have wheels but have hundreds of doors? And you have planes? And skyscrapers?" said one TikTok user, who also picked doors as his answer. "Lego made 2 billion wheels, how often do you change your doors vs car wheels?" another user asked. "Yes, 'Think of a big office and how many doors it has' but how many chairs in there? One door VS 4 wheels on the chair."

The debate soon took a turn with users 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 @RealNeil3 asked. "If cogs and gears are being counted as wheels, you have to include valves as doors. Every heart has valves. Billions upon billions of bugs. Doors wins," tweeted @M1dgar. Responding to a TikTok that claimed heart valves should count as doors, tennis player Coco Gauff said: "Well if heart valves are counting, then blood cells count as wheels."

Finally, the Twitter poll provided something of an answer as over 53 percent of Nixon's pollsters said there were more wheels than doors on Earth. What do you think? Are there more doors or wheels in the world?
