Please don't assume to know what I think and don't distort what I have said nor the validity of what you have said. You have posted nothing which demonstrates reciprocity nor spatial contraction without ignoring the dilated clock used to time the trip distance traveled. I repeat once again that I have not argued against what one "Sees". I am, and have always, insisted that the only time dilation being considered is the physical dilation demonstrated by clocks on subsequent comparison to some relative velocity having been generated. Perception of an observer in motion is not at issue here. (Although that is another arguement which should be tackled). Your example proved nothing which is why it is ignored. Now adddress the issue I presented [post=878738]Here[/post] and stop trying to dodge the issue by writting your own gendankins and making different claims. Do not alter my gendankin. Just answer it.
