This episode starts with a crash, after an eclipse and power cut in the studio leave our presenters stumbling around in the dark while Mr Mounfield later reveals himself to be a Zoroastrian. It all proves however, to be a perfect link for their guest, Gregory Sams, who puts forward a compelling argument for the sun, stars and universe being far more intelligent than conventional science would have us believe.
