Exploring Gravity and Dark Matter

This is a re-airing of a podcast originally released in February 2021.

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 podcast are Rowan Hooper, Anna Demming and Timothy Revell.
