After a week of learning physics I completed it in 6th try. U know why I say this was hard because this physics was new to me atleast my grades will be good (hehe) anyways This is black hole simulation this black hole eats stardust for breakfast and likes larger mass i used Schwarzschild metric it looks like this (ds² = -(1 - 2GM/(c²r)) c²dt² + (1 - 2GM/(c²r))⁻¹ dr² + r²dθ² + r²sin²θdϕ²
) but i simlified it. U can try it
