Business Insider UK sat down with Dr Stuart Clark, who spoke to us about a range of subjects regarding astronomy and astrophysics. We asked him what he thought of flat earth theory, a school of thought which believes that the earth is not spherical but flat.

"All our physics is constructed now, the physics of orbits of things going around the earth is all constructed with this three dimensional world. And the pictures from space show our world as a globe and yet somehow there are some people that still seem to believe the earth is flat."

"My own pet theory is that they’re doing it for comic effect."
