What are the physics of time?

What are the metaphysics of time? This ePhilosopher notice caught my eye, having recently posted that time might have a specific geometry, and true enough, the "topology of time" is listed as one of the subjects on which the conference organizers are soliciting abstracts. Others:

  • The reality of the past
  • The specious present
  • The open future
  • The nature of passage
  • The flow of time
  • The direction of time
  • Time-travel
  • The philosophical significance of relativity
  • Beginning and ending
  • God and eternity.

Too bad the subject matter is so narrow! No matter. Whether wrinkled or fuzzy, time appears to be getting more attention these days.
