  This is a chapter of the planned monograph "Out of Nowhere: The Emergence of
Spacetime in Quantum Theories of Gravity", co-authored by Nick Huggett and
Christian W\"uthrich and under contract with Oxford University Press. (More
information at www.beyondspacetime.net.) This chapter investigates the meaning
and significance of string theoretic dualities, arguing that they reveal a
surprising physical indeterminateness to spacetime.
