  We provide strong evidence for single-electron spatial dynamics with a
macroscopic discontinuity. The dynamics is observed in an electron quantum
phase consisted of macroscopic quantum orbits similar to those responsible for
the integer quantum Hall effect. The dynamics is consistent with the standard
QM that predicts a "cloud-like" behavior of electron in quantum orbits
regardless of their lengthscale. Sinse the dynamics is beyond the relativistic
paradigm of movement, it may well be nonlocal. It thereby can be the basis for
a quantum concept of absolute simultaneity, which now rests not on the
meaningless notion of infinite speed but on empirically-tested quantum effect.
This concept revives the Bell-Popper idea to replace the current "kinematic"
version of relativity by the "dynamic" version by Lorentz and Poincare with a
revival of the classical view of space and time where the problem of preferred
reference frame now can be solved without to involve the vague notion "aether".
We argue that the concept of quantum absolute simultaneity opens the door to a
realistic interpretation of standard QM through a deeper insight of what is
called "reality" and ultimately to a harmony between quantum and relativity
theories.
