Simulation of deflection of light by the Sun

Description:

The gravitational deflection of light by the Sun is simulated.

Controls:

 

Slider "Angle Star-Sun when RUN is hit":
        Choose the angle between the Star and the Sun as viewed from the Earth.

 

Button "RUN":
     Run a simulation. This button or one of the buttons below must be operated after change of angle between Star-Sun.

 

Button "Set theory to Newton/GR":
     Choose  if the simulation should be done according to Newton's theory or the General Theory of Relativity.

 

Button "Set view to Enhanced/Normal":

Choose  between "Normal view"  where both the Sun and the Earth will be shown,

and "Enhanced view" where the dimension perpendicular to the direction to the source is amplified so that the deflection becomes more obvious.

      

Button "Set distance to star 409ly / = ∞":
       
Choose the source to be either a star at infinite distance in the ecliptic plane, or the star 13 Tauri which is at distance 409 light years in the ecliptic plane.

 

You can run the simulation as an Application, se how here
