While I was out last night revisiting 3C 273 and thinking of the fact that is
moving away from us at 16% the speed of light, 47840000 metres per sec
(47840 KM/S) as mentioned above. Then light traveling from 3C 273 to
my retina must be traveling at 86% of the speed of light, right?
As would be the case say if we were instead located on the opposite side
of 3C 273 so it was traveling towards us at 16% the speed of light. Then
light from 3C 273 would be hitting my retina at the speed of light plus 16%
and not taking into account that we now know or suspect that the speed
of light is variable.
Anyone have any thoughts on this
