1. ## Time dilation dependence on direction

To Janus: Thx for answering, I know what's wrong wiht me, I have a clearer understanding
2. ## Time dilation dependence on direction

Someone redirect my post so you don't see my previous message Imagine a space craft is moving towards me with speed 0.6C, I shoot a laser with frequency "f" to a spacecraft,the reflected laser frequency should be 2.56f, right? But for the people inside spacecraft, the frequency of original and reflected laser must be the same The what happened?

3. ## Time dilation dependence on direction

I think of this question for a long time too, no one give meaningfully answer to this..... I understand in case of light shoot out and than reflect back the time dilation calculation is correct for all direction But consider different path, In view light speed is constant:- A object moving towards us, its time should run faster than us A object moving away us, its time should run slower than us Its a simple calculation but no one can tell what's happening
