The first intergalactic spaceship is headed toward the Magellanic Clouds at a speed of 0.8c. The spaceship is 1000 m long. Clocks at the front and the rear of the spaceship both read 3:00 P.M. Can it be 3:00 P.M. simultaneously at the front and the back of the spaceship?
A)No, because $\Delta t=\gamma \beta \frac{\Delta x}{c}$ , where $\Delta$x is the length of the spaceship.
B)No, because one clock has to move after being synchronised with the other.
C)Yes, because $\Delta$x in (a) is zero for different points of the same spaceship.
D)Yes, because two clocks at rest relative to each other can be synchronised by means of light signals when the distance between them is known.
E)The question cannot be answered unless we know the object relative to which the spaceship's velocity is 0.8c.
