Dying In Space, Trapped Water, and What's Hidden In Pi?
Summary
Hosts Hannah Fry and Michael Stevens explore the tragic 1971 Soyuz 11 mission, where three cosmonauts became the first humans to die in space due to a pressure leak. The episode also debunks viral claims about water trapped in landfilled plastic bottles and the "monkey trap" myth, while discussing the mathematical uncertainty of whether Pi contains every possible number sequence.
