So, you don't think educated people could possibly understand something you don't. Interesting.

I have answered your question. Why won't you read the answer? ______________________________ No you have not. It is a really simple question. Here it is again: Earth moving at v relative to the ether. We measure the speed of light on earth in the direction we are travelling through the ether. What speed do we measure on earth for light? Instead of saying that you have already answered it (which you haven't), why not just tell us the answer?

Because to understand the answer you need to read my posts having to do with a train moving at speed 'v' with respect to the aether. Why not read the answer already posted? |
