A spacecraft flies past Earth at a speed approaching the speed of light. One of the creatures on board takes a selfie with Earth in the background. The flash is bright enough to be seen by an observer on Earth in daylight. Which of the following would be correct?  Time for the earthling would pass slower than for the alien.  Time for the alien would pass slower than for the earthling.  The speed of light for the observer would be greater.  The speed of light for the observer would be smaller.
