I've got two things to say:
1. read my post.
2. Boring!
1. read my post.

2. Boring!
It is a purely hypothetical questiuon. there could never be sucht objects as the ones in the question. (as you yourself have pointed out before, Alpha). I would like to keep it theorertiocal. IThe thing is you can't keep going half the distance. Eventually the minimum distance you can go is more than half the distance. Everything is quantized.
