DESCRIPTION:Speaker: Stefan Wolf\nAbstract: The hardness of explaining non-
 local correlations in a fixed causal structure supports the view that spac
 e and time might not be fundamental. Dropping causality has a number of co
 nsequences. First\, the usual definitions of randomness cease to make sens
 e. We thus discuss an intrinsic\, context-free randomness notion based on 
 the work value of a bit string. We test it in the context of Bell-type non
 -locality and end up with a reasoning about the phenomenon not invoking ou
 tcomes of unperformed measurements\; it is\, in this sense\, conceptually 
 simpler than the traditional probabilistic view. A second consequence of d
 ropping causality is the potential appearance of logical paradoxes. We sho
 w that saving logical consistency does not restore causality\, but is stri
 ctly weaker. Finally\, we use the adopted complexity-based view to specula
 te whether the second law of thermodynamics can be related to the logical 
 reversibility of a system's evolution.
