 We have speed of light, haven't we?
 So, how do you come to 'instantaneous'?

It is the structure of space-time that makes things as they are, but as the human mind does not want them to be.
The pack spirit is most often a spirit of laziness.
We do as the other does without asking questions, because it is painful and distressing, very tiring to ask questions, and man is naturally lazy (in civilian life, how many lazy people for one courageous man?)
If someone tries to calculate the infinite speed of light, he will never be able to do it, and it will take a new Michelson to find an experiment capable of doing it (perhaps from the experiments of Alain Aspect).
In the meantime, it is very complicated, and for 40 years, I have not found an idea to experiment to prove it.
Certainly, if we place two watches at A and B, we will have t=AB/c but this equation can also be written t=AB.And where Et is the universal transverse spatial anisochrony.
And what do I do when I calculate c, if not place myself in a transverse position each time?
So we find in a circle.
In any case, the concept that I give is certain, because it alone explains the Langevin paradox in a truly credible way (which avoids the unjustified objections of cranks and anti-relativists).
If you want a correct reasoning, you are obliged to go through the relativistic zoom effect, and this cannot be done either without an instantaneous interaction of light in the longitudinal direction.
I repeat, there exists for each observer, each entity of the universe a hyperplane of simultaneity. Everyone agrees on that.
But for me, it is personal, relative.
All the elements of a given frame have their own.
Physicists do not want to hear this.
They then come to imagine an abstract and false theory, with a common and absolute present time hyperplane for the entire frame.
This is obviously ridiculous and the opposite is easily demonstrable mathematically since we have a mathematical absurdity on apparent speeds), but not experimentally for the moment.
