Does the Universe Create Itself?
Summary
PBS Space Time explores John Archibald Wheeler’s “It from Bit” hypothesis, arguing that reality is fundamentally informational and defined through the interaction between observers and the universe. The episode details Wheeler’s delayed-choice experiments and the “participatory universe” concept, where observation helps create physical reality. It also contrasts this view with other quantum interpretations like Many Worlds and Copenhagen, before addressing listener questions on cosmic expansion and the possibility of the universe being a black hole.
