An experimenter has studied the decay of a K° particle in which it emits a pion at 0.8c. One such K° particle passes the experimenter at 0.5c and decays, emitting a pion in the original direction of motion. In the experimenter's frame, the speed of the particle is measured to be O between .8c and c. O 1.3c. O between c and 1.3c. O between .5c and .8c.

Suppose our Sun is about to explode. In an effort to escape, we depart in a spaceship at v = 0.80c and head toward the star Tau Ceti, 12 lightyears away. When we reach the midpoint of our journey from the Earth, we see our Sun explode and, unfortunately, at the same instant we see Tau Ceti explode as well. (a) In the spaceship’s frame of reference, should we conclude that the two explosions occurred simultaneously? If not, which occurred first? (b) In a frame of reference in which the Sun and Tau Ceti are at rest, did they explode simultaneously? If not, which exploded first?
