In DOI: 10.13189/ujpa.2023.170101, Figure 4 depicts a thought
experiment involving FTL communication. This figure is
attached to this post. We, the viewers, are at rest with
observers A and B.
At event E1, observer A, at x = 0, t = vL/c^2, sends an
infinitely-fast tachyon signal to observer B, who receives
it at x = L, t = vL/c^2. B immediately passes it to D, who
who is getting it before E1 happened.
Or isn't he, poor halfbrain?
