Some gravity particles

[User137]

Went and bought Universe sandbox on Steam sales, now that it's under 4 euros.

It is getting a bit laggy with 50000 asteroids orbiting the star in the screenshot. But these asteroids are most likely not orbiting eachother. Either way, lots of things this app can do, with creative mind.

I tested Universe Sandbox a wile ago while it was still free alpha and it is quite good.
As for the asteroids I don't think Universe Sandbox calculates atraction between them.
Even in reality asteroids usually have so low gravity that they can't affect each other until they get realy close to each other.
