| Time as a dimension would only fix the past. Other phenomena such as
| QM may leave the future open.
May? What is this, conjecture?
|
| Your model does not concur with your previous statements where the
| past and future do not exist.
Show where I made that statement. Then ask... was it in the past, perhaps?
This is your model:
|
| yesterday (-) now (0) tomorrow (+)
| nothing | nothing
That is your model. My model is
yesterday (-) now (0) tomorrow (+)

| But the now has no duration either so is also nothing. There is no

"Except" ?
That exception is all we need. It's recorded right here, as we write.
Nothing magical about it. Magic refers to the supernatural. This
is not supernatural, this is a natural as it comes.

| Albro Swift points out that moving bodies differ depending on which
| observer views them because their coordinate systems are different.
| The problem of what distinguishes a moving from a non-moving system is
| therefore resolved, just look at the clocks.
