The MIT bag model is shown to be wrong because the bag pressure cannot beheld constant, and the volume can be fixed in terms of it. The bag derivationof Regge's trajectories is invalidated by an integration of the energy andangular momentum over all values of the radius up to $r_0=c/\omega$. This givesthe absurd result that "total" angular momentum decreases as the frequencyincreases. The correct expression for the angular momentum is obtained fromhyperbolic geometry of constant negative curvature $r_0$. When the square ofthe relativistic mass is introduced, it gives a negative intercept which is theEuclidean value of the angular momentum. Regge trajectories are simplystatements of the conservation of angular momentum in hyperbolic space. Thefrequencies and values of the angular momentum are in remarkable agreement withexperiment.
