Here I will collect some points where I'm critical of some aspects of relativistic mainstream physics. To clarify: special as well as general relativity have been, without any doubt, great advances of physics in comparison with pre-relativistic theories. And even if my own ether theory will be successful, this status will not be questioned: Instead, the Einstein equations of General Relativity would remain the natural limit $$\Xi,\Upsilon\to 0$$ of my own theory.
