I got an n-body gravity simulator! and… this is what I do with it. Payoff is 18s in. (only 5m of work but oddly frustrating uploading it – now trying AVI. Yikes)
t’s beautifully organized when in time order. Calculations include non-linear gravitational effects. Smashing galaxies and things.
But out of time sequence and I think it’s a bit more accurate to working with stuff at that scale.
