I want to know the answer to the following question:
The crew's perception of what is different from a stationary observer?
All the background I'm provided with is that "On the other hand, the crew on board the spaceship also perceives the observer as slowed down and flattened along the spaceship's direction of travel, because both are moving at very nearly the speed of light relative to each other.". Is that enough to answer the question?
Answer: no
