Hi, I'm Alessandro Pioli, a recent computer science graduate, 29, Italian. The project I built in the 6 months after graduating, <https://github.com/alessandro-pioli/AstroCausal_Engine> , is a 2+1D gravity simulator where gravitational information propagates at the finite speed c. My goal is to collect feedback of any kind, to understand whether and how much it can be improved, and where it stands in the eyes of amateurs and professionals.
