On the v and c in the Lorentz transformation

The measured invariance of the velocity of light leads to the Lorentz transformation. But what does the Lorentz transformation tell us about the invariance of the velocity of light? And what does the Lorentz transformation tell us about the maximum velocity in the universe? In these articles we look at what we exactly can and cannot conclude from the parameters v and c in the Lorentz transformation.

On the v and c in the Lorentz transformation and absence of movement
The v in the Lorentz transformation is the velocity of the origin of the second frame of reference. A point/location which has no dimension. We can not conclude a maximum velocity (or anything) for physical objects from this v. In the Lorentz transformation the velocity of light c is the velocity of information in the measurement. We can take any value c for the velocity of information.

Lorentz transformation – a conversation
We have a conversation between two people. Person A starts with an observations on the v in the Lorentz transformation. Person B holds on to the theory of relativity. The conversation shows who has to prove what and why.
