Did you tell him that the idea of 3D time was fully developed and published back in 1959 by Dewey Larson, in The Structure of the Physical Universe?

Something's got to give

You should have told him that we always assume that we (matter) move N, E, S, W, Up, Down in time uniformly in all directions (pseudoscalarly) and when our assumptions don't agree with what really is happening, then something's got to give and we have to adjust our perception of motion in space to compensate ...as a result of these assumptions, strains/force fields appear to us.

In our minds, we constantly normalize our temporal motion to a uniform outward pseudoscalar motion (motion in all available directions).

This intuitive temporal normalization gets us into a lot of conceptual trouble.

I personally gave Neil a copy of "Nothing but Motion" while he was giving my wife and me a guided tour of the Rose Center a little over 4 years ago. Just maybe he read it!

Yes indeed time is three diemensional but not cubic. Time is 3-D spherical shell that is rotating and expanding and contracting in perfect simultineity with hypercubic space that also expands and contracts.

Imagine a ball inside a box that expands and contracts as it rotates. This is spiral motion. All that we observe in nature is spiral.
