Naive realism might ask today: Tell me what space is in itself, not in terms of other things. Tell me what a gluon is at bottom, or a neutrino, or a charge.

The so-called spin crisis has had important effects beyond simply confronting theorists with a particularly sharp challenge to their incomplete understanding of quantum chromodynamics, the underlying field theory of quarks and the gluons that mediate their strong interactions.

Lattice QCD explores the particle realm by taking a different tack. It simulates quark and gluon behaviors by applying the full QCD theory to a tiny grid like facsimile of the space-time in which particles actually interact.
