I forgot to say that Einstein himself revised his idea about the unnecessary ether in his 2 relativity theory by saying the opposite in 1920 because of new discoveries of Bohr atom...
«The important fact that, according to Bohr’s theory, the frequency of emitted radiation is not determined by electrically
charged masses undergoing periodic processes of the same frequency can only strengthen our doubt of the independent reality of the
wave field.
But even if these possibilities mature into real theories, we are not going to be able to dispense with the ether in theoretical physics,
that is, with the continuum furnished with physical properties; because the general theory of relativity, whose fundamental aspects
physicists will probably always retain, excludes any unmediated action-at-a-distance. However, every theory of contact action presupposes continuous fields, hence also the existence of an "ether.» Einstein 1920 article " On ether"...
Then good luck to debunk that claim of Einstein cindyment by using Einstein apparent dismissal of Tesla ether by VULGARIZATORS AND ENGINEERS who think relativity theory displace Tesla ether........Relativity theory was unable to negate Tesla ether ....
Tesla ether was NEVER dismissed, just let there to dry unattended under the sun so to speak.....
Tesla ether was an idea abandonned by scientist who did not want to tested Tesla devices and work with them anymore at all...
Einstein say the samething differently in a book in 1922:
«Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense. But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it.»
