When I create a simulation of a hard ball rolling in a hard bowl, the ball eventually loses energy, slows down, and stops. Think of the bowl as curved spacetime and the ball as ... a ball. :)
Since the simulated ball will be in a hard vacuum there should be nothing to slow it down. Thus I want the ball to continue to roll with the same energy until I stick something else in the way.
I have tried turning off all damping for the bowl and the ball, friction to zero, bounciness to zero, and rotation to zero and it still slows down.
I have been thinking of using scripting to add a slight boost to the velocity every few frames, but I am hoping that there is an easier way. Any suggestions?
