Negative moving coordinates and Time Dilation

[chinglu1998]

I think the three of you should take your arguments back to the other forum. It is rather impolite to register on a new forum for the purpose of continuing an argument that was already banned or moderated in another forum. I don't think it is explicitly against the rules, but it is certainly not a way to make a good impression.

Agreed, I should not brought moderator's comments. That is my fault.

But, they followed me here and I just want to discuss this narrow topic of OP in this forum to explore further.

If you are OK with the interpretation of your first post in that a particle moves with uniform speed from x = 0 to x = 1/5 light seconds. And if you are OK with the interpretation of your confused presentation that this takes 3/5 second, how in the world do you object to the calculation of the particle's speed as w = Δx/Δt = c/3 ?

It is my apologies I brought your comment here.

However, a moving clock is at (-1/5,0,0) in the moving coordinates and moves to (1/5,0,0) in the stationary coordinates. So, your statement is not what I wrote.

Anyway, if you would like to continue this discussion of this topic in your forum, simply remove the suspension and we can continue. We still more to discuss since you can now know w = Δx/Δt = c/3 is false based on (-1/5,0,0) moving coordinate which moves to stationary coordinate (1/5,0,0) all in view of stationary system.

Again, apologies that I brought your comments here.
