"The fact that that could be news all over the world just shows you how it is," Irving told reporters Saturday. "The fact that it's a social phenomenon -- 'Kyrie thinks the world is flat' -- is hilarious to me. ... That it could actually be news."
"This is not even a conspiracy theory," Irving told Jefferson and Frye while recording the podcast on an airplane. "The Earth is flat. The Earth is flat. ... It's right in front of our faces. I'm telling you, it's right in front of our faces. They lie to us."
He reiterated those beliefs to ESPN's Arash Markazi on Friday.
"I think people should do their own research, man," Irving told ESPN. "Hopefully they'll either back my belief or they'll throw it in the water. But I think it's interesting for people to find out on their own.
"I've seen a lot of things that my educational system has said that was real that turned out to be completely fake. I don't mind going against the grain in terms of my thoughts."
On Saturday, after being peppered with questions, Irving explained his thinking further.
"I think that there's just so much, I guess -- I don't know if you can even call it news -- there are so many real things going on, actual, like, things that are going on that's changing the shape, the way of our lives. And I think it sometimes gets skewed because of who we are in the basketball world, and, 'Oh man, what does he actually think? Oh, no, I don't like hearing ... the world is flat, or he thinks the world can't be round.'
"You know, I know the science, I know everything possible -- not everything possible -- but the fact that that actually could be real news, that people are actually asking me that -- 'It's a social phenomenon. What do you think about it? Are you going to try to protect your image?' I mean, it really doesn't matter. It really doesn't matter. The fact that it's a conversation? I'm glad that it got people talking like this: 'Kyrie actually thinks the world is flat.'"
LeBron James, asked Saturday about his teammates' comments, said Irving was "an interesting guy."
"Kyrie is my little brother. He's my All-Star point guard, superstar point guard, and if he decides he wants to say the Earth is flat, so be it," James said. "He's an interesting guy, and he believes it."
Even commissioner Adam Silver weighed in on the conversation Saturday night.
"As he made clear today, he was trying to be provocative, and I think it was effective," Silver said. "A larger commentary on the so-called fake news debate in our society right now in terms of what's reported, and it led to an interesting conversation.
"But personally I believe the earth is round."
