Thanks for the posts but I still have some questions.

Imagine a spacecraft moving close to the speed of light. Observer 1 is in the spacecraft and observer 2 is outside. I am trying to keep in mind that speed is distance/time and the person is aging slower traveling near the speed of light.

They both are holding a flashlight in the same direction and turn them on exactly when they are next to eachother.

Will observer 1 see the 2nd flashlight moving across space in slow motion? In relation to observer 2's stationary position will the 1st flashlight be moving faster? Will it apear to observer 2 that the 1st flashlight is affected by a dopler effect because the source of the light is moving close the the speed of the light? Thanks in advance.
