In the gedanken experiment shown in Fig. 26.16, two events in the same inertial reference frame O are related by cause and effect: (1) A gun at the origin fires a bullet along the x-axis with a speed of 300 m/s. (Assume that there are no gravitational or frictional forces.) (2) The bullet hits a target at x = + 300 m. Show, using qualitative arguments, that the two events cannot be viewed simultaneously by any inertial observer.
Answer to relevant QuestionsIn a gedanken experiment (Fig. 26.17), two events that cannot be related by cause and effect occur in the same inertial reference frame O: (1) Strobe light A, at the origin of the x- axis, flashes; (2) strobe light B, ...An astronaut in a spacecraft moves past a field 100 m long (according to a person standing on the field) and parallel to the field’s length at a speed of 0.75c.
