    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Galaxy

u/pavel

300 bodies which individually only interact with an infinite mass at the center
u/pavel

Each body moves around an ellipse, the orbits are accurate. However, the movement speed is a very rough approximation.
u/pavel

Naively drawing an ellipse centers it around one of the focal points, however moving a body on this path slows the body down near this focal point and speeds it up near the other one.
u/pavel

The opposite effect is needed. So this code still moves a body around an ellipse but it re-centers the ellipse on the 'other' focal point.
u/pavel

In polar coordinates the difference between the x and y coordinates is a phase shift of pi/2 ~ 1.6
