Back again , I got headache trying to understand all these information :) .
In this great link of PeterDonis
http://en.wikipedia.org/wiki/Speed_of_light#Astronomical_measurements
We will find some different techniques to measure the speed of light, I didn't understand the first method related...
OK , I thank you very very much Peter for your great help .
I need to revise myself again and again , there are missing items I should know about and link between them all .
Can you tell me an example for such an experiment or give me a link to it , sorry Peter for bothering you , so sorry
Same request please
Why did he predict a difference in speed of light in different directions ?
I got confused again :(
First of all I should apologize about some sentences like " Focus with me " and so on.
I really didn't mean something bad , I was just talking , that's all , but the Admin drew my attention to that point, so I am sorry again :)
As for you my dear PeterDonis , I'll try to make my point clear...
God bless you ...God bless you ... haaaaaahahaha ... thank you very very very much Peter...Finally now I understand ...and You were right .. the Problem is my personal mistaken ideas... I really thank you very much :) :) ... so , what I was talking about wasn't fully wrong ...it is just I didn't...
What is not proper in my english ?
ok .. read that ... I hope it would clear my Point to you
ok i will explain what i got from this theory ...the speed of light in vacuum always the same ... ok ... but how can we get to this fact ...by measurement of course ...ok ? ..now you said ...
Dear Peter , you left the concept and criticized the example ...ok ... let's talk as real ...please Peter stand me .. Go with me to the end ... because I really want to understand ...First question .. How could the scientists know that the speed of light in vacuum is 300,000 km/s ? ... Knowing...
ok i will explain what i got from this theory ...the speed of light in vacuum always the same ... ok ... but how can we get to this fact ...by measurement of course ...ok ? ..now you said ... the speed of light is constant to any observer ...and that's is very important ..to any observer...
That's what i am talking about ...as long as it is impossible the detectors travel along the light beam or the moving source of the light beam ... how our outsider detectors detect a constant speed ... as they not affected by dilatation of time ... when we calculate ... we calculate per its...
and that's what i am talking about ... in this this method we calculate per our not dilates scale of time ... so when we apply the same technique to detect the speed of light from a mobile source ... why we detect a constant speed as long as the method is mathematical and the instrument is...
ok ok you are right i don't disagree with you ... but as you said ..The instruments that measure the speed of light are affected by time dilatation if they are in motion...if they are in motion ...but when scientists do that they don't use instruments in motion ... that's what i am talking...
It is very important for me to know how scientists detect the speed of light in details...because there is something confuses me ...einstein concluded the dilatation of time on basis of that the speed of light is constant even if it comes from a mobile source ... but this fact is supposed to be...
