If these particles travel at 2.49 x 10 m/s and live 2.60 x 10-3 s when at rest relative to an observer, how long (in s) do they live as viewed in the laboratory? (b) A spaceship, 170 m long as seen on board, moves by the Earth at 0.922c. What is its length (in m) as measured by an Earth-bound observer? m

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?
