💡 Drag Light Source (Amber) or Lens (Cyan Ring) to observe real-time photon geodesic warping.
The saved lensing simulator uses a drawn Einstein-radius proxy eighty times the square root of its normalized mass slider divided by fifty. At slider twenty-five it is about fifty-six point five seven source pixels; at one hundred it is about one hundred thirteen point one four. The circles use the same two-video-pixels-per-source-pixel scale, and their radii have ratio two. Their areas have ratio four. This source slider is not a rigorous physical mass-and-distance lens solver. The source impact ratio is absolute vertical separation divided by its drawn radius, with a lower floor point zero one. It computes magnification as u squared plus two divided by u times square root of u squared plus four. At ratio one the result is about one point three four one six. At ratio two it is about one point zero six zero seven. Both bars show magnification at four hundred twenty pixels per unit. Source history retains each sampled horizontal coordinate and magnification; these values are demonstration outputs, not observations of a particular galaxy. At normalized slider fifty, the full branch radius is eighty source pixels. Switching to the Newtonian branch divides that radius by square root of two, giving about fifty-six point five seven. Both circles share the same radius scale. At fixed vertical separation this changes the impact ratio and therefore the modeled magnification as well. The physical solar-mass text uses a separate exponential mapping of the slider, so these drawn radii are not a consistency proof of full relativistic geometry. Treat the export and annotations as the saved model conventions.
