Dying In Space, Trapped Water, and What's Hidden In Pi?
Summary
Hannah Fry and Michael Stevens explore the three cosmonauts who died in space during the Soyuz 11 mission, detailing the tragic pressure loss that occurred above the Kármán line. The hosts also debunk the myth that discarded water bottles permanently trap fresh water in landfills, explaining how compaction and decomposition allow the water to return to the cycle. Finally, they clarify that while pi contains all short digit sequences, it is not yet proven to be a normal number, meaning not every phone number is guaranteed to be hidden within its infinite digits.
