that, according to Lorentz, we cannot detect our motion due to contraction and dilation of ourselves, but simply cannot notice that, because our...
It is often about frame - "stationary" or "moving". Is here any difference? What is "moving"?

As far as I understand, if something "moves" relatively to me, it means it changes spatial coordinate in my frame. As I understand,, "my frame" is an...
Maybe, while writing the first chapter, Einstein still was convinced in existence of Ether, but changed his mind later, while writing the second chapter?
Oh, guys, Mein Gott, so much complex theory!
Well, but Wikipedia is very reputable source and the second postulate sounds exactly as it is in the Einstein's paper. I don't believe, that the author of these words - "in at least one" added them due to misunderstanding.
Why this person - @Ibix says that
Why do not they strike the mirrors...
Once my understanding of the 2nd postulate was something like that:
Let's say there are 2 points of reference frame ##K##, we can denote these points as ##A## and ##B##. Speed of light between these points is ##c##, that doesn’t depend on chosen direction, ##A## to ##B## or ##B## to ##A##...
It is clear from the article, that in moving frame propagation times along the legs is the same, because of Lorentz contraction of longitudinal leg. Lorentz contraction makes propagation times the same, it is obvious, that in moving frame speed of light is longitudinal direction is not c. It is...
Could you please to clarify one little detail in regard of this sentence? Can we say about ourselves that we are relatively at rest (and our interferometer is not contracted and speed of light is c in our frame) or can we say that we on Earth are moving ourselves relatively to someone and speed...
Hmm... but the Earth and the Sun is the real – life example...
Well, as far as I understand, explanation of Michelson Morley experiment cannot be reduced to the simple model of Special Relativity, since there are some non - inertiality. As far as I understand, quite complex for average Joe...
Yes, but the result of the experiment in simple words can be explained either by contraction of the interferometer (velocity of light is different from ##c##) or by absence of it (velocity of light is ##c##). We don't speak about sophisticated philosophy but about real experiment that had been...
Hello,
I do not fully understand nature of Lorentz contraction. Is it bona fide effect or not?

The article says:
“This allows a more elegant and intuitive explanation of the Michelson-Morley null result. In a comoving frame...
