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...
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...
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?
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...
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...
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...
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...
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.
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.
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...
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...
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...
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...
