The mathematical definition of hyperplane match with the definition
of hyperplane of simultaneity (not "present") sure.

 I gave my definition of the present time hyperplane, of the simultaneity hyperplane.
You will notice that at first, this seems to be close to what physicists and also AI say.
It is in the relative concept of this hyperplane that I no longer agree with all this.
For the public, scientists, and AI, it seems that this hyperplane is a kind of absolute block in a given frame of reference, and that we can make all the spatial translations we want and the block remains unchanged. In short, that it is only modified by the notion of relativity of speeds between frames of reference (i.e. chronotropy).
This idea is as silly as it is false.
Which does not mean that people are ready to listen to me.
Au fait, elle vient ta définition à toi, que je me marre (il va nous sortir un copier-coller de quelque part, je le sens). Autant dire tout de suite que si c'est un copier-coller plus ou moins proche de ce qu'on trouve sur les sites relativistes ou sur les sites d'intelligence artificielle, c'est pas le peine de te fatiguer.
