The flaw in your reasoning here is the assumption that, in the 
observer's frame, it will take 2.1 years for the light emitted from Big 
Ben (BB) to reach Proxima Centauri (PC). This assumption is incorrect 
because in the observer's frame PC is moving at 0.867c away from the 
light that is heading towards it. In the 15.79 years light takes for the 
journey, PC moves 13.69 light years. When added to the 2.l light year 
separation from BB, that adds up to the 15.79 light years that the light 
has to travel.

At some point, I'm going to tire of explaining to you where your 
analyses have gone wrong, and stop doing it. No doubt you will then 
claim it's because I cannot. Other readers, if there are any, will 
likely see the true situation, which is that you consistently get this 
stuff wrong, and that your "contradiction" is nothing but your piling 
mistake on mistake.

Sylvia.
