[PD] The Party at the Center of the Universe

[Ed Kelly]

If you're into physical particle systems, Cyrille & Damien Henry have a
mass/spring plugin, which was called PMPD when I saw their performance.  
Else, GridFlow could do things like that too, but it can also do density
models, which are more like "we have the space and then there's matter in
it" whereas particle systems are more like "we have matter and then it's
somewhere in space".
PMPD  would be a good tool for exploring gravity - but you would have to  explore the escape velocity scenario, where links (springs) are broken  if an object attains a certain angular momentum, and a different  (repulsive) mechanism comes into effect (and what about dark  matter/energy or as it should be termed, the foo fudge factor (FooFF)).
  
  Also - how fast is your computer? They normally use supercomputers to  do this, I think you may have problems on a standard machine. Modelling  aspects of the universe such as doppler shift would be easy, but it's a  problem of scale...perhaps you ahould start with a solar system?
  
  Best,
  Ed
