Umm so you're no longer standing by the assertion, that was incorrectly attributed to me, that the changing of the mirror's angle is compensated by the changing of the light's reflected angle due to time dilation. I said it's one or the other in relativity, length contraction does not work in tandem with time dilation. If you try to do the math with both of them contributing to an effect, they don't cancel out, they add up to double the effect with Y2.
There's no such thing as physical length contraction or time dilation. It's all handled by relativity of simultaneity and it's all illusion. Time does not slow nor does length contract. What's happening is the information of time or distance is delayed by the speed of light. Velocity adds a rate of delay of that information. If you had a camera on the face of your alarm clock and your alarm clock was speeding away from you, the rate of information being transmitted to you would be received slowed while all the while your alarm clock is ticking away normally. It is not ticking slower due to being in some sort of slow time warp as Dildostein said.
People just don't seem to understand the difference between clocks and time. Einstein tied the two together when he said time is what clocks measure. Colbert illustrated this in his monologue when he as Trump was calling Australia to find out if he was going to make any mistakes tomorrow because they are 14 hours in the future. Sounds ridiculous unless Einstein says the same thing. The future or the past are not what's on a clock face. Time dilation is not slowed time just because you can see the face of a clock look like it's measuring slowed time. All you're witnessing is the information from that clock face being affected by a rate of light delay. Why can no one in the world understand this?
Perspective brings in relativity of simultaneity. Because a ray of light is involved between the mirror and eyepiece, the information that it represents is affected by the velocity of the ship. The information is the relative position between the mirror and eyepiece and the time it takes light to traverse that distance. It's like refraction in water. The water bends the light so distances look off. Velocity is adding a rate of delay to the light but the actual distance between the mirror and eyepiece remains unaffected.
Now I know Popeye will ignore all this because he has a ship to catch and is too busy to try to understand it. The thing is, I give him a lot more credit than the philosophers on this "science" forum. His motivation is not that he has better things to do, his motivation is fear that I'll confuse him and his stature in the flock of parrots will be compromised. Unlike Dumbamp, I see no problem in ad hom, ad hominem, admonition, addition/subtraction, and double poisoned wells because you can't really understand where a person is coming from unless you understand his motivation. For example, Damp and XC's motivation is preserving their intelligence (manhood) from attack through dishonesty.
