Re: Redshift -
BBT claims that galaxies and stars are not moving but space between them expands/grows. If they are not moving why do scientists think that non-moving objects should cause a redshift?
​
Either all or most of the red shift has nothing to do with motion through space. The light is moving in space and when the space is stretched the light is s t r e t c h e d out.
​
(at least that is my non-professional understanding )
