time seen as the 4th space dimension is also a result of
Einstein-Minkowski theory. It wasn't the only step in that direction, not
the first step, but it was a major shift. There's a version of Pythagoras'
theorem for that space-time, in which the only difference between space
and time is that they have a different sign. Thus time is a kind of space
with a scale factor equal to square root of -1. (You may also get to this
scale factor by fiddling with the wave equation.)

Whether time "moves" or "stays exactly where it is" is a metaphysical
question: you can't make an experiment that distinguishes the two
possibilities. Thus it's just a matter of how we explain things to
ourselves.

I think that there is hope in reversing the roles of time and space in
equations, such that you have 1-D space and 3-D time. I don't think that
we'd be able to get to exactly 2-D time. Thus I believe that there is more
hope in [line~~~] than in [line~~].

As far as I am concerned, time is just one of the two main dimensions in music, the one that allows the other one(pitch/frequency) to exist, or at least to be realisable by my ears and brain.

If i may now borrow the theory and terminus Arrow of time by Arthur Eddington, according to which time is the fourth dimension in space, it has a direction and moves only to this direction, making everything in the past clear and stable, but leaving the future uncertain.
(One could wonder: Exactly how straight is this axis? Could it bend and go back? Of course! In music this is called a "reprise".)

So, is there ever going to be a [line~~]? Only "time" can tell.
