Are we confined to only finite positive values? If so, are there upper or lower limits? I’m kinda curious about how the game would go with a ball smaller than a spec of dust. Or how about a court twice the size of the observable universe?
Densities can get very interesting too if the ball collapses under its own mass into a singularity? Or how about a ball with neutron star density without the gravity to push it together? This is getting into the what if territory again.
