Supernovae 3 - Solution

  1. A and D simultaneously, then B, then C, then E.
  2. D, then A and B simultaneously, then C and E simultaneously.
  3. B, then A and D simultaneously, then C, then E.
  4. D, then B and C and E simultaneously, then A.
  5. The chronological order of A and E is NOT the same in all frames of reference. The spacetime points A and E cannot be connected by an object or signal which travels slower than the speed of light. They are outside of each others light-cones. Therefore, their chronological order will depend on the frame.
