Burst 28 - The Cosmic Archipelago, part III

Released: 6 February 2018

Duration: 24 minutes, 48 seconds

 

A hundred years ago cosmologists were struggling to understand the nature and structure of the universe, and at the heart of this struggle was the island universe hypothesis. Today we find ourselves confronted with a similar question posed at a far greater scale. In order to resolve our cosmic archipelago problem we will have to attempt to reconstruct a history of our universe as a part of a far larger cosmological system, and to do this we will have to extend cosmology beyond the observable universe -- but what, exactly, is the observable universe?
