Sorry, I wasnt clear. what I meant is that spaceship A and B accelerate in a way such that the distance between then as measured by A or B is always the same, i.e. the spaceship A and B are behaving like the train example you talked about later. Basically, consider A as the head and B as the...

While what you said make sense, I am more confused about the implications of your statement. Could you please answer a few simple questions regarding my example, hopefully that will clear things up for me. The moment when spaceship A observes that distant start, S stops at A, what does A see...

Ok, i see what you are saying. Now I have one more follow-up question. So for two inertial frames that are at rest with respect to each other, should any event appear to be identical to observers on both frames? Also, I guess ultimately, I am really curious about, in my example, what is the...

Thanks Stephanus, while I am still trying to process your post (It might take a while). I just have a few quick questions first. "c. Due to the length contraction, E should [add: see] B “jump” 0.433 light year towards E almost instantly, No, there's no "jump" here. :smile: I have thread asking...

In this case the distance is defined from either spaceship A or B, since they both accelerate, but keep the same distance from spaceships' point of view. So through out the whole journey, spaceship A will always see spaceship B at 0.866 light years behind it. Its kinda like reversed bell's...

Since I am new to the forum here, I apologize in advance that in case similar example has been explained in another thread. If so, please kindly refer me to the appropriate place to read further. In my example, there will be four reference objects, earth, E, distant star, S, spaceship A, and...
