Homework Help: Forward light-cones and special relativity

  1. Dec 13, 2017 #1
    1. The problem statement, all variables and given/known data
    How can we tell that quantum effects do not propagate along forward light-cones that represent two separate events? How do light-cones demonstrate this notion of quantum effects?

    2. Relevant equations

    3. The attempt at a solution
    We don't know which events occur first given different spacetime equations

    I'm having trouble make sense of this question. Where did it come from?

    A light cone consists of an infinity of points in spacetime, so what do you mean by "light cones that represent two separate events"? Do you mean 2 light cones having their respective apexes at separate events?
