Lets say its the future your camera has an insanely fast shutter speed. You're standing on the ground watching a train travel past at just under the speed of light and the train driver is shining a laser pointer out the front window. With your insanely fast reflexes you take a take a picture of the train (or better yet you record a video). Would you see the laser light slowly moving ahead of the train, or would you see the laser beam traveling ahead of the train at full speed? If its the latter, I'm mighty confused because I can't see how you would record normal light speed for the laser beam, rather than light speed + the speed of the train. If its the former then I think I'm starting to get my head around special relativity.
