Meet The Northwest's Leading Flat-Earther: Sound Effect, Episode 127.5

Gabriel Spitzer
Mark Sargent is fed up with the globe sham.


When it comes to scientific arguments nowadays, there’s a good chance sooner or later someone will be compared to people who believe the earth is flat.

Most would consider that an insult, but not Mark Sargent. The Whidbey Island resident spends much of his time promoting the belief that the earth is not round or spherical but actually, definitely flat.

He’s not joking. And he claims that there is plenty of proof out there to prove him right. That is why Sargent created Flat Earth Clues, a series of Youtube videos that have garnered hundreds of thousands of views.

Despite wide agreement that this theory was debunked sometime around the 3rd century BC, Sargent feels there is a growing movement in America and abroad that can’t let go of a flat earth.

In this midweek installment of Sound Effect's podcast, contributing producer Shane Mehling and host Gabriel Spitzer discuss how this story came to be, and how they navigated the dilemmas of producing it. 

Note: This is part of an experiment with Sound Effect’s podcast: We will feed a condensed version of the full show on Saturdays, withholding an especially memorable story. Then we’ll hear that segment, and some of the story behind the story, in a new weekly podcast installment that will be in your feed on Wednesdays. You can still always catch the full, broadcast-style version of the show on the web site (at the bottom of the page).

We’d love to hear what you think of the new podcast format -- give your feedback in the comments below, or email
