Abstract
Closed time-like curves (CTCs) naturally appear in a variety of chronology- violating space-times. In these space-times, the principle of self-consiste ncy demands a harmony between local and global affairs that excludes grandf ather-like paradoxes. However, self-existing objects trapped in CTCs are no t seemingly avoided by the standard interpretation of this principle, usual ly constrained to a dynamical framework. In this letter Re discuss whether we are committed to accept an ontology with self-existing objects if CTCs a ctually occur in the universe. In addition, the epistemological status of t he principle of self-consistency is analyzed and a discussion on the inform ation flux through CTCs is presented.
