In episode 6, Stu and Mark discuss the moon, exciting goings-on at the Large Hadron Collider, answer listener questions, play 'Stuniversity Challenge' (aka Big Fat Galactic Liar Quiz), talk about the perils of asking the public to name things, and dwell briefly on Mark's new beard... and Matt Damon's poo (the two are unrelated).   See acast.com/privacy for privacy and opt-out information.
