  We consider one of the fundamental debates in performing the relativity
theory, namely, the ether and the relativity points of view, in a way to aid
the learning of the subjects. In addition, we present our views and prospects
while describing the issues that being accessible to many physicists and
allowing broader views. Also, we very briefly review the two almost recent
observations of the Webb redshift and the ultra high-energy cosmic rays, and
the modified relativity models that have been presented to justify them,
wherein we express that these justifications have not been performed via a
single model with a single mechanism.
