My interpretation of 4D Space-time is from a future perspective on the time
axis looking down on the zero intersect with the 3D spatial axis called the
"present". This narrow time interval is only measurable differentially since
our time perception is based on relative motion between the fabric of time
though space. We can only measure accumulated time dilation measured between
different inertial frames such as the twin paradox. C and Bohr radius always
appear constant within our inertial frame. At a micro level a temporal
perspective would show an orbital forming a halo with different length
vortexes,depending on their acceleration, down to their nuclei much like the
coffee analogy of Ron Mallet. The faster Ron stirs his coffee the more the
frothy center contracts but the vortex also extend further down into the
coffee. Ron suggests we can only see the coffee surface in our 3D world. I
would extend this to include relativity by suggesting the radius of the
frothy center always looks like the same length to us and C always seems
constant because the vortex going down into the coffee changes to keep the
volume constant and that our time perception inside the "Present" is based
on that volume. It suggests time is a narrow ribbon that creates our 3D
illusion of reality much like an electron gun traces out a 2d image on a TV
screen. From this perspective we exist in an extremely narrow ribbon at the
intersect of Future and Past.
