I understand I cannot push a light ray (I mean, to sum speed vectors) in its propagation path,
but ¿why I can certainly sum speed vectors (clasical mechanics) in the normal direction to the light ray?

Please, I am not looking for opinions nor comments, but just academic sites where the answer to this question have been scientifically developed.

I have not found any info on this matter in any text on special relativity theory and I do not understand how could anyone talk about special relativity without previously explaning such bizarre anisotropy of light.

many thanks for your help

Many thanks for any help, indeed.

It will be easier to answer your question if you have
learned some electromagnetic theory. Have you? One model
of light is of a propagating wave with a changing electric
field component and a changing magnetic field component.
A changing electric field induces a changing magnetic
field. A changing magnetic field induces a changing
electric field. The traveling EM wave propagates in this
way. The kicker is that the model satisfies the experimentally
verified equations of EM theory, _but_ if you imagine
yourself traveling along at the same speed as the EM wave
what you would _observe_ does _not_ satisfy the equations
of EM theory.

There are other models of light, and none of them
work with an observer traveling at light speed.

Another model is that two material bodies are electromagnetically
coupled and the space-time interval between a transition
in one and the coupled transition in the other is zero.
Since the space-time interval is zero the two transitions
are in a sense the _same_ event. There is no way to push
an indivisible event.
