What would we experience if the world were a four dimensional Block in which the
future already exists? My own view is that “we” would experience nothing since such a Block would
correspond to a world that had run its course and everything would already be over. At our current stage
of understanding of fundamental physics, however, this debate about the empirical consequences of a Block universeview cannot be resolved. I will instead show that taking the view that the
physical world “becomes’’ has proved to be a useful heuristic in one approach to quantum gravity, causal
set theory. That is, one approach to the problem of quantum gravity has been
fruitfully influenced by the view that we can escape the Block and that time really passes.
