elementary particles display a preference for left over right.

They don't call 'em elementary for nothin'!

[MHGinTN]

The left-handed ones summ for gravity and the right-handed ones sum for anti-gravity. Why do we have large mass objects? Because the natural 'place' for right-handeds is at the peripheri of the solar systems, but they exist in thin amounts throughout an entire solar system just as lefties exist in thin amopunts at the 'edge' of a solar system but tend to concentrate within the visible mass total.
