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

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~~].
