Recently, an unapproved CMS study indicates that there appears to be a QCD bound state approximately 300MeV below the 2$\eta_b$ threshold. An obvious candidate for this would be a stable (in QCD) four quark bound-state composed of two bottom-quarks and two anti-bottom quarks: $bb\bar{b}\bar{b}$. This system has generated significant attention in the literature from model-dependent calculations. This talk will discuss the exciting search for this tetraquark state using the first-principles lattice QCD methodology and give a conclusive statement about the existence of such a tetraquark.
