You must have both. > those galaxies would NOT shrink in length to zero, But that contradicts your previous post, you said there were no discontinuities and length contraction, time dilation, and mass increase continuously and does not stop suddenly at some point short of the speed of light. Einstein says from our viewpoint distant galaxies can be arbitrarily thin and the clocks in them can be arbitrarily slow. What do you say?
