Gravitational Universe Demo

Gravity in space. Binaries and massive singularities are exhibited.

A massive singularity is unstable at under 7 masses. A rare multiple massive singularities is depicted in the scenario icon.

Use 'up' and 'down' arrows to alter body count.

Thanks. Awesome work. In world you use "Particle a, Particle b" but i dont see where did u make it is it passibly to use variable without makeing it? Or "Particle a = particles.get(j);" u make it here? Im just confused becouse i dont see any "stirng" or "int"

@Nahquin, I first created a List object filled with all Particle objects in the world (named 'particles'). All particles in the list must interact with every other particle in the list. So, all different pairs of particles ('a' and 'b') are taken from the list (using the 'get' method) and passed to the 'interact' method where their gravitational interaction is applied.

If you add too many they all clump together

@nolttr21, Yes, a "black" hole is created; and it will try to pull the entire universe into itself. It is a massive singularity I mentioned in the description.

Very fascinating visualization of the universe!

Could be interesting if the universe has no boundary to see the reaction of the particles and how the gravity looks like.
