"It's really concerning when you have people in the public eye who think the Earth might not be round," Nye told SI. "It's really an extraordinary thing."

Nye continued, saying that he thinks it is damaging considering all of the technology humans use that rely on the spherical shape of the planet.

"We have spacecrafts, we all depend on weather reports," Nye said. "We've got mobile phones, we're talking on electric computer machines. So to have people that eschew or don't accept this method, this process that brought us all this remarkable technology... all this is through the process of science. And so it's heartbreaking when we have people even joking about it."

Iring doubled-down on his flat-earth beliefs at the All-Star Game this weekend.
