Claims about time

It’s time to list the claims about time made in this series of blog posts.

  1. Time is 3-dimensional. This is the over-arching claim which is explained and expanded by the other claims.
  2. Time is duration with direction. That is, time is a vector variable similar to a position vector in space.
  3. Time as ordinarily conceived is parametric time. That is, time along a trajectory, curve, path, route, trip, etc.
  4. Time has continuous symmetries of homogeneity and isotropy.
  5. Time and space are symmetric with one another.
  6. Minkowski spacetime should be expanded to six dimensions. That is, the invariant distance should be: (ds)² = (c dt1)² + (c dt2)² + (c dt3)² – (dx1)² – (dx2)² – (dx3.
  7. Replacing time with its negation produces a duration in the opposite direction. It does not reverse time or switch past and future.

I am working on a paper that explains and defends these claims.
