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

- Time is 3-dimensional. This is the over-arching claim which is explained and expanded by the other claims.
- Time is duration with direction. That is, time is a vector variable similar to a position vector in space.
- Time as ordinarily conceived is parametric time. That is, time along a trajectory, curve, path, route, trip, etc.
- Time has continuous symmetries of homogeneity and isotropy.
- Time and space are symmetric with one another.
- Minkowski spacetime should be expanded to six dimensions. That is, the invariant distance should be: (
*ds*)² = (*c dt*)² + (_{1}*c dt*)² + (_{2}*c dt*)² – (_{3}*dx*)² – (_{1}*dx*)² – (_{2}*dx*)²_{3}*.* - 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.
