Time is perpendicular to the inertial frame.
The observational differences between space and time are
manifested by virtue of our reference. That is, matter is space
that travels through time, and energy is time that travels
through space. However, everything travels, so everything is in
a mixed phase relationship. If either dimension becomes static,
it turns to pure matter or energy.
Because we, as observers, are based more on a matter
phase relationship, we perceive time to be the mobile dimension,
when in actuality, all things are mobile. We just happen to
exist in the inertial frame.
But I think the main point is that time and space are not
interchangeable. They have a relationship. You can't simply
transform one to the other. The inertial frame isolates time as
the mobile dimension. All things tend to seek the same inertial
frame. It is this frame that determines the direction of time.
