Hey everyone. This is my first post, and I apologize if my question is too stupid for this forum. I bought Steven Hawking's book a few years ago but was too lazy to read it up till now. A few pages later I read that speed of light is constant in in every frame of reference( sorry for the non-physics English). I decided to stop reading until I understand that fully and I imagined a few examples. I want to share them with you and ask you if I'm getting this or if I'm completely off. Hope I'm not too boring. Say I and my friend are on spaceships next to each other. 6 lightseconds away (same distance from both spaceships) someone decides to send a Ben Affleck picture via wireless. Now a picture wont upset my friend, so he doesn't do anything, but It will upset me so I decide to run away from the event in the opposite direction. If light moves with a constant speed for any observer does this mean that no matter how fast I move Ben Affleck will always get to me in 6 seconds. If this is true then suppose an event happens in all directions, like a star exploding. Does this mean that the time when the waves from that star wipe out everyone depends on, if you look at it this way, the distance they were away from the star at the moment of explosion, no matter how fast they are moving. Does this apply for change in trajectory or acceleration? Sounds pretty counter-intuitive so I'm probably getting everything totally wrong. Maybe my example is flawed. So please tell me if I got the absolute basics at least. Train coming towards me flashes its light in my direction. For me the speed of light is C, not C+(train speed), right?
