Talk: Nick Huggett

The Geneva Symmetry Group, Beyond Spacetime, and the Space and Time After Quantum Gravity Project are happy to present the following talk:

Nick Huggett (University of Illinois, Chicago):
What Does it Take to Explain Spacetime?

Wednesday, 2 December 2015, 18:15 (Please note the later time)

2, Rue De-Candolle, Room L107 [Map: http://www.openstreetmap.org/]

Anyone who wishes to attend this talk is welcome. The talk will be 2 Einsteins (out of 5).

Abstract: “In earlier work, Chris Wüthrich and I addressed the question of ‘physical salience’ in the explanation of spacetime, raised by Tim Maudlin. In this talk (the result of continuing collaboration) I aim, with examples, to further explicate the role that physical salience plays in the reduction of one physical level to another (using those terms loosely): in short, physical salience is a stronger ontological condition than ‘mere derivability’. (Though our knowledge of physical salience will ultimately rest on the derivation of empirical predictions.) I then turn to the question of whether the demand of physical salience might be satisfied in an explanation of the appearance of spacetime in terms of  non-spatiotemporal physics: I will sketch the example of non-commutative geometry in accessible terms.”
