#4 Mass: From lightest creatures on earth, to the heaviest things in the cosmos

From some of the lightest creatures on earth, to the heaviest things in the cosmos, this episode is all about mass. It’s a magical opening to the show as the team discusses a group of insects called fairy wasps which are so light it’s near impossible to weigh them. They then turn to matters of massive proportions, discussing a little thing called dark matter. Finally the team wraps up by looking at the surprising, and slightly hilarious ways that a kilogram is measured. On the pod are Rowan Hooper, Anna Demming and Timothy Revell.
