i found a word "extinction" in a book "Special Relativity" By French, A.P. 1971. It's written that from the incident light, the glass 0.005cm thick is enough to extinguish the memory of light source's motion. What ?? Is the light speed equalized in the medium ? If so, what about above thought experiment (on pillar made of glass) ? What about Fizeau experiment (Imagine an observer and the glass that move together) ??
It's written also that the air 0.1mm thick is enough to "extinction". Is the result of Michelson-Morley experiment explained (and only this explanation alone is reasonable ??) ? If so, bad dream (But, in encyclopedias of physics, the word "extinction" seems to mean other matter).
