I read elsewhere that when one travels in a spaceship "very close to the speed of light" that objects behind the ship (light emitters that the spaceship is accelerating away from) start to appear to the side and eventually toward the front. This is based on SR, contraction, etc. and is posited as a valid effect due to Relativity. There is even a movie on one website showing the effect. I find this scenario impossible to square with Relativity, if for no other reason than - no matter how fast one thinks one is traveling, one always measures the same c. What one would see is the light in front shifting in perceived frequency since the wavelength is seen as shorter (I believe this is blue shift), and light from behind shifting the opposite way (red shift) due to the perceived wavelength getting longer. but would the direction of light coming from an object astern ever appear to come from somewhere other than from behind?(adsbygoogle = window.adsbygoogle || []).push({});

help?

thanks,
