Problem: Draw a space-time diagram illustrating the following:
- Two inertial observers moving with respect to each other meet at event E_1.
- For observer O, the events E_1 and a distant event E_2 are simultaneous according to O (Draw the hyperplane of simultaneity, including E_2).
- Suppose that for the second observer O', E_1 occurs before E_2, according to O'.
- Draw the hyperplane of simultaneity for O'.
