Atomic Time is Perfect Time in constant μ0ε0
Explanation
Atomic clocks are based on a reference to the impedance of space. Their timing will change as the impedance of the space they are in changes. Further, their references are affected by their orientation to the contours of Z0. This is why they are shielded from both the electromagnetic and electrostatic effects of the environment they are in. Atomic clocks are, in fact, a good measuring device for the impedance of space. As such, they prove the CA concept and debunk the idea of relativity with a little thought!
