Question
(a) Find the value of $\gamma$ for the following situation. An Earth-bound observer measures 23.9 h to have passed while signals from a high-velocity space probe indicate that 24.0 h have passed on board. (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
1. 0.996
2. $\gamma > 1$ implies $v > c$, which is impossible.
3. A proper time that is longer than relativistic time is not reasonable. Either $t$ should be greater, or $t_o$ is smaller.
