Question

The pilot of an interstellar spaceship traveling at 0.88c determines the diameter of a galaxy to be about $1.50 \times 10^{14}$ km. What value would a stationary observer calculate for the galaxy's diameter?

Step 1

Let $L$ be the length (diameter) of the galaxy as measured by the pilot of the spaceship traveling at $v = 0.88c$. We are given that $L = 1.50 \times 10^{14}$ km. The velocity of the spaceship is $v = 0.88c$, where $c$ is the speed of light. Show more…
