Einstein was wrong
It was not about where we were on the issue it's that I felt like I had acted like a bully. Maybe you didn't read it that way and maybe he didn't either. I'm really only accountable to myself and my maker; I felt that my actions required an apology and so I gave it.
I don't really care what satisfies your various dogs.
Einstein was not always correct. (or was being misquoted) And I believe his attitude on the speed of light being maximum attainable speed is just ignorant (again - or misquoted).
Out in space - for every action there is an equal and opposite reaction. You burn the rockets and you get an increase in speed.
On earth we deal with wind resistance, water resistance, and gravity.
In outer space - unless you are near one or more galaxies - there is no friction and no resistance. Unless you try to turn or change directions (centrifugal force).
Einstein treated light as if it was holy. He was in love with light as a constant for a universe in much slower motion. He believed that light always left and arrived at the same speed. Science magazines and newspapers loved him. They would not print anything else.
So I ask you: If when the earth is doing its yearly orbit around the sun, and you pick a distant galaxy to measure the light from. When the earth is moving around the sun toward that galaxy or one half year later moving away from that galaxy is the light speed the same in both cases.
If you say yes then there is something wrong with determining the speed of light as an exact number. Or there is something wrong with the way they are trying to measure it.
For me the truth is that there is no good way "yet" to do such measurements. How would light know how much to slow down to compensate for the reading of the other.
It is what makes math teachers sometimes sound like politicians.
One honest physicist said that Einstein Said "the speed of light is always the same in any frame".
Or if you are shining a flashlight on the earth you are in the earth frame (frame of reference). If you are on the moon shining a light you are on the Moon Frame (frame of reference).
