15. Read the description of a thought experiment designed to check whether
time is an absolute concept. Say if the statements below are true or false.
Correct the false ones.
Figure 15 shows a spaceship traveling past Earth at high speed. The person
on the spaceship (a) flashes a light and measures the time it takes the light to
travel across the spaceship and return after reflecting from a mirror. The
observer on Earth observes the same process. Both observers have accurate
clocks.
Figure 15.
1. To the observer on Earth the light going across the spaceship and returning to
the sender after reflecting off the mirror travels the diagonal path because the
spaceship is moving (T/F).
