Abstract:
In this illustrated essay I hope to demonstrate how the speed of light, 'c', is constant, regardless of the motion of the source, or of the 'inertial reference frame' of the observers, without the requirement of time or length contraction for its explanation. With the following diagrams, the passage of light is observed by a fast travelling observer, and by two other observers, in this case, considered as being 'static'. I am not a mathematician and, to be honest, do not trust equations that include letters that can represent any number, even although I can see that this allows generalisations to be made over many circumstances. Instead of using 'v' or 'x' or 't' etc, to discuss the position of a space ship in time and space in a generalised way, I plot out precise positions on a graph where there can be no concerns about the use of 'complex numbers'
