  • Time travel of information. May be an interesting topic on the Physics SE :-) – peterh - Reinstate Monica Apr 20 '17 at 2:55
  • @Gnemlock doesn't strike me as implausible the data backfill didn't get run/complete for SF&F – Jon Clements Apr 20 '17 at 6:02
  • @peterh Time travel is probably more on-topic on Science Fiction & Fantasy than Physics :-) – Rand al'Thor Apr 20 '17 at 11:20
  • Science Fiction seems to drive science. Yesterday's magic is today's science fiction, tomorrow's science experiment, and next week's fact of life. I seem to recall some reports in particle physics of pre-event effects. That could lead to time travel of information, as suggested by @peterh, without necessarily leading to actual, physical, time travel itself. The science fiction version, the science experiment version. – user351780 Apr 21 '17 at 3:58
