New version, year 2 AC (After Claude)

Let's ask Claude to push the limit of my previous version… Super impressive!

You are probably here for the BIGGEEEEER version of the project, and to get your eyes full of stars ! Welcome ! I asked my dear Claude to improve my previous project, and he did some magic... The super hyper mega HPC version of the code can now simulate millions of bodies on my M4 Mac in a few hours... Here I will briefly explain the physics and the pipeline, but without any more suspense, on to the impressive results!

Two galaxies

A disk galaxy encounters a companion. A filament appears and spiral arms form.

The encounter of the two galaxies.

A toy universe

A high-density random cloud with an outward velocity expands, and the gravitational force creates filaments.

A toy universe: a smooth cloud grows into a cosmic web.
The same run, with a zoom.
