Those of you in the US might not know who Freddie Flintoff is, but here in the UK he's a pretty famous cricketer who was instrumental in England's defeat of Australia in the 2005 Ashes series.
He might be good at cricket, but it appears he's not that good at science. Speaking on a podcast for BBC 5 Live in the UK last week, he expressed some rather bizarre views and said there was evidence suggesting the world wasn't round.
"If you're in a helicopter and you hover, why does the Earth not come to you if it's round?" he asked his co-hosts. The answer, dear Freddie, is relativity.
He also didn't understand why water stayed still if we were hurtling through space (gravity), and why you can see a laser that you fire into the distance. Not sure what he's going on about here.
"The middle is the North Pole, around the outside is the South Pole which is like a big wall of ice," he said. "This is why all governments now have bases on the South Pole."
I, uh... okay. I see.
A. J. Styles/Sherri Shepherd
Okay, so WWE wrestler Styles didn't explicity say he thought Earth was flat, but he did make some comments that alluded to the fact he might believe just that.
"I don't think the world is flat, I'm just saying there's some stuff about it," he said earlier this year. "That's all. I'm not a flat earther. I'm just saying there's some things about it that make sense."
Then there was Sherri Shepherd, who was given quite a hard time for comments she made on The View back in 2007.
When asked if the world was flat by Whoopi Goldberg, she responded: "I don't know. I never thought about it Whoopi. Is the world flat? I never thought about it. I tell you what I thought about, how I'm going to feed my child."
Shepherd got a huge amount of stick for the comments, and later clarified that she didn't think the Earth was flat.
But it goes to show that, when it comes to Earth being flat, you're probably best to stick on the side of science.
