Why Is Uranium The Most Feared Element On Earth?

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/3qYsIDs... Somewhere beneath you, half of all the uranium our planet was born with is still waiting. It is barely radioactive, its radiation stopped by skin, and it once made dinner plates shine and glass glow green. Yet two billion years ago, in African rock, it did something no one noticed until 1972. So why does this quiet grey metal frighten the world more than any other element? Tonight is a slow walk through quantum walls, a miners' disease, snow in Sweden, a secret city and a seventh bucket. Get comfortable and let this slow journey into the heaviest element nature left us keep you company tonight.
