Upcoming talk: “Time Machines: Some Recent Work”

I will be giving the following talk in Turku, Finland on June 9 at the 10th International Conference on Unconventional Computation:

“Time Machines: Some Recent Work”

Abstract: I will consider some recent work on time machines within a particular research program (Krasnikov 2002, 2009; Earman, Smeenk, Wüthrich 2009; Manchak 2009, 2011). The background theory is classical general relativity and the upshot is that there are “time machines” if we assume spacetime is free of “holes”. The talk will make precise what is meant by these words.
