Birth of a galaxy

After the webinar offered by SideFx I felt inspired to try my own custom forces. Basically here I created realistic gravity pull towards the sun and towards each particle, making also a absorb particle behavior so close particles will absorb smaller ones within certain parameters. My idea was basically to create a space opera scene ala Interstellar/Alien. But the main objective was trying vex and vops and having fun making my own forces.
