Planetary collisions

[Elite Jacob]

Does someone else remember a program made to simulate the potential outcome of the collisions of celestial objects?

Could you use this? http://universesandbox.com/download/ I've never actually tried it myself but I stumbled upon it awhile ago and I've been meaning to give it a go. I don't know for sure, but I think it will probably be able to simulate collisions.
