Algodoo

this is the algodoo equalivent of a actual neutron star this uses water because it acts like gas like in real life the core is a circle as its the most stable this star is maintained by the water putting extreme pressure but the core attracts the water strongly enough that it compresses the water much like how compressed a gas is in a neutron star this behaves like a neutron star and is accurate to one

basically algodoo water = gas in the universe when no gravity
