I guess it means I've seen Mersenne twisters generate more valid rankings than TIOBE, same as every other month.
Their methodology is that of an insufferable buttock clown.
This does not necessarily mean that physical infinities exist; it may mean simply that the theory is incapable of describing the situation properly. Two other examples occur in inverse-square force laws of the gravitational force equation of Newtonian gravity and Coulomb's law of electrostatics. At r=0 these equations evaluate to infinities.
