In our first episode of the New Year, Dan and Alice decide to provide a free existential crisis for both themselves and our listeners (no refunds). We discuss the microscopic worlds living around (and within us), from atoms to bacteria to water bears. We even dip into the numbers of humans on our fair planet and just how little space we can all squeeze into! Find our sources on twitter @nerhourspod.

Content warning: germaphobia/bacillophobia, general discussion of the immense scale of our micro/macroverse could be upsetting for some listeners
