• Aberration of the position of the stars

    From Richard Hachel@21:1/5 to All on Sat Feb 8 23:42:55 2025
    Aberration of the position of the stars all all objet in the universe
    (like this horse in this prairy).

    Physicists understand and accept (at least I hope so)
    the notion of aberration of the position of the stars (although I am not
    sure that they fully understood its meaning, because I have seen some who
    made rotations instead of a translation in x).

    I explained, a very long time ago, how it should be done,
    and although all this is very simple, I saw with astonishment that not
    only did people not understand, but that in addition, they spat on me.

    I recall here, with a small diagram how it works.

    Here, two observers cross paths, and start their watch.

    At the instant t'=t=0 this is what they perceive.
