Nothing is too bizarre for someone who advocates G=mc^2, Greg, though it might not be all that bizarre if Einstein was correct in his assessment that objects are not "in space" but spatially extended - and I would further propose, extended via gravitational time dilation, or redshifted due the deceleration of light instead of the acceleration of space.
With time being the sole factor in creating spatial perception, Newton's absolute frame is always fully-accelerated/expanded because there is no time in the absolute frame, and Einstein's relativity allows for wavelength changes through variable media without changing Newton's absolute frame of light.
The other thing, not that your explanations are ever unclear, the proposed illusory acceleration of the reflected image at greater than the velocity of light could only be accurate if both the mirror and reflected image velocities were to be combined; but if the reflected image only is measured as it appears to the observer, the velocity of the reflected image would not exceed "slightly more than half the velocity of light."  |
