At the time of creating a scene Phun I found this, a strange movement or bug.
What happens is that I have a red mass on the right of the scene with one attracting 10,000 and 2 masses on the left with tracers and their normal physical conditions (0.5 friction, restitution 0.5, but the density is infinite 1.99999999999999 ... , and became so because the masses are very small) and a mass of 0.009484.
Well, back to my observation, the red mass attracts mass small but I guess it should be attracted and attached to the red mass, but begin to "orbit". And finally fired emerging (unknown causes)
I think that is the mass of bodies with tracers are very small mass and cross the red. Well at least that's my theory
But you as a catalog this: as a bug, strange movement or only are the physics?
P.S: And you can do what they want to find the causes of this effect
