| A de Sitter universe is one where there is no matter or radiation, only a cosmological constant. | |
| create particles which are affected by nothing but each others' gravity, and then let the particles move. | |
| give particles an initial velocity, and then run the system. | |
| Could be a nice little toy which does some quite cool stuff. Also might be a nice exercise in optimisation, since it will probably be crazily inefficient to calculate the mutual gravity of all the particles in the system once you go beyond a relatively small number. | |
