Kyrie apologizes to science teachers for spreading flat-Earth conspiracies

Kyrie Irving has once again weighed in on the shape of the planet he calls home. Hopefully for the last time, he says.

The Boston Celtics' star was asked to clarify his previous - and widely lampooned - statements about the shape of Earth during a discussion at the Forbes Under 30 Summit. The 26-year-old appeared to regret suggesting the planet is flat.

"Hopefully after this, I'm done answering these kinds of questions," Irving said with a laugh.

Irving said his anti-science skepticism came from falling down the proverbial YouTube rabbit hole.

"At the time, I just didn't realize the effect," Irving said of his declarations, which ignored hundreds of years of scientific progress. "I was definitely like, 'I'm a big conspiracy theorist, you can't tell me anything.' So, I'm sorry about all that. For all the science teachers, everybody coming up to me like, 'I have to re-teach my whole curriculum,' I'm sorry. I apologize."

While Irving's insistence on the planet being flat was largely derided, some of his more impressionable fans bought into the rhetoric. Last year, a middle-school teacher said that some of his students became flat-Earth truthers after listening to Irving's guest appearance on a podcast hosted by former teammates Richard Jefferson and Channing Frye.
