Here is your statement above, There is nothing correct about your reasoning above. There is no sequence of transforms that goes from (20,0) to (30,50). Here is your post #31. t = γ (t' + vx/c^2) = (1.25) (-15 + .6 *25) = 0 x = γ (x' + vt') = (1.25) (25 + .6 * (-15)) = 20 B' frame...- Whatifitaint

Okay, I like your change to sync the clocks. I did not think of it and that is very good. So, what we have for the laws of physics at the clock sync is both C and B' are co-located and the lightning is located at (20,0,0) in the coordinates of the C frame with t=0 because of the clock sync...- Whatifitaint

Okay, is it the physical reality of your proposed experiment above when the clocks sync, C says the lightning strike is at (20,0,0) with t=0? Is this the undisputed physical reality of C?- Whatifitaint

These are your calculations based on the B' interpretation, not the other way around. Please read your post. I agree C will calculate this as the B' now in the future. But, this is in the future for C since t=0 and for this x=50 and t=30. t=30 is not the now for C at the clock sync. This...- Whatifitaint

I am sorry, I am not following you. You wrote Two observers in relative motion disagree on "now" I completely agree with this, but this has nothing to do with what I said. I totally agree with you that each frame will have a different interpretation of now for any given event. But, if C claims...- Whatifitaint

I agree with everything above. Even though this is a little different, it has the same issue in it. C observer view of now and lightning at A when the clocks are synched, t = γ (t' + vx/c^2) = (1.25) (-15 + .6 *25) = 0 x = γ (x' + vt') = (1.25) (25 + .6 * (-15)) = 20 B' frame...- Whatifitaint

Thanks, please let me turn this into logical statements. Please explain why this logic that I learned is false. Let statement P = B' and C are colocated. Let statement Q = the lightning flash is located at A in the space-time of C. Then, we have C claiming, Special relativity...- Whatifitaint

I do not know what the t coordinate for A' is. I know the t' coordinate is A'/c for A'. And, you are not understanding. I want to see a 4D vector in the transformation for B' view. Can you say it is different from the A view vector of (A, 0, 0, A/c)? This is yes or no.- Whatifitaint

That's odd, we do not know how far apart B' and C are. How can this be decided? Either way, say A is the view of the C frame. Here is the question, does B' claim A' translates to A when B' and C are colocated as does C? This is a yes or no.- Whatifitaint

His diagram does not include the translation of A' to C coordinates. I want this simply written down for its value. Can you do this?- Whatifitaint

I am not getting it. We all agree C says A when B' and C are colocated. Now, you have not given the view of B' for where the lightning is located in C coordinates when B' and C are colocated. That is a logical known for B' using lorentz transformations. Let's put it down in writing. I...- Whatifitaint

You are still not answering the question. Try to translate A' to C coordinates. Use the lorentz transformations. Where does B' think the lightning strike is in the coordinates of C when C and B' are colocated. We already know that C thinks it is A. What does B' think it is in C space-time...- Whatifitaint

Can you please instead of asserting I refuse to accept different now's, which I have not done, instead answer the question? C claims A is the lightning location when B' and C are colocated. What does B' claim, when B' and C are colocated, the location of the lightning is in the...- Whatifitaint

Wow, misspelling I meant cos'(\apple pie), joke. Yes, cos(\pi). And, the direction of v is based on the motion of the frames not the light beams. We are not communicating. So, let's ignore -A for now which is a shorthand of writing (-A,0,0). We know frame C says when B' and C are...- Whatifitaint
