If you want to check the simulation: at our velocity of \( v=0.97 c\) the light rays from the Janus circle are seen in agreement with the Theory of Relativity at an angle of 14° to the direction of motion as compared to 90° if we were at rest and as compared to (90° - 20.5 arcseconds) if we moved like the earth around the sun at \( v= 0,000\,1c \).
Other important effects of motion are the change of the position, the Doppler shift of colours and the changed luminosity. We neglect the latter two effects in our flight through Stonehenge for simplicity.
