Inspired by the recent image
Inspired by the recent image of the Powehi m87 black hole from the Event Horizon Telescope, I visualize the behavior or light (photons) following the path of spacetime around the black hole in p5.js. Code: https://thecodingtrain.com/challenges...
p5.js Web Editor Sketches:
🕹️ Black Hole Visualization - Newtonian Granvitational Attraction: https://editor.p5js.org/codingtrain/s...
🕹️ Black Hole Visualization - Code with Relativistic Corrections: https://editor.p5js.org/codingtrain/s...
