Here is an updated list of claims about time made in this series of blog posts:
- Time has 3-dimensions. 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 space vector (a distance with a direction).
- The magnitude of time is that which is measured by a stopwatch, similar to a length, which has beginning and ending points.
- Division of two vectors is a vector with the direction of the numerator, which is why time in the denominator has not been recognized as a vector.
- The spatial and temporal perspectives are complementary opposites.
- Time has continuous symmetries of homogeneity and isotropy (as does space).
- Time and space are symmetric with one another, and so may be conceptually interchanged.
- Minkowski spacetime could be expanded to six dimensions, three for time and three for space. The invariant distance could be: (ds)² = (c dtx)² + (c dty)² + (c dtz)² – (drx)² – (dry)² – (drz)².
- 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.
