“For months now, Rebecca had felt what she could only describe as a certain subtle wrongness – not within herself, but in the world. She found it impossible to place its source, for the fault in the nature of things seemed to reside both everywhere and nowhere. Countless things just felt a little off to her.”
In “Version Control” by Dexter Palmer
A lot of the debate around this book must be surely undermined by the lack of a clear definition of time.
The idea of time 'moving forwards or backwards' is just a metaphor that people adopt because it's easy to identify with physical objects that move and since time is a dimension- a dimension of space-time, the continuum in which everything has its being. Time itself doesn't 'move' or 'pass' any more than length can pass or move. However, everything moves, or occupies a series of different points, in space-time. I also suspect that our perception of time as a progression in one direction, with a remembered past and a future of multiple unrealized possibilities, is a 'fiction' or mental construction that allows us to make sense of cause and effect. If we could imagine a being outside of space-time, whether God, or Vonnegut's Tralfamadoreans, that being would see all those points simultaneously. As we do when we remember someone's life.
