Question 1 (marks: 2+2 = 4) S is an inertial reference frame and E1 = (3c, 2c, 0,2c) E2 = (4c, -C, 0,2c) E3 = (-2c, -c, 0, -2c) are the coordinates in space time of three events with respect to that reference frame. (a) What events are causally connected? (b) Draw a light cone. From the answer of (a), identify the region where each of these events may take place. (HINT: You don't have to show the exact coordinates of the events, drawing a 4D space in a 2D paper is impossible anyway! Just showing the approximate region of the events would be enough. You can draw separate cones to describe causal connections between different events.)
