The '''non-critical string theory''' describes the relativistic string without enforcing the critical dimension. Although this allows the construction of a string theory in 4 spacetime dimensions, such a theory usually does not describe a Lorentz invariant background. Thus it is not a suitable [[theory of everything]]. However, there are recent developments which make possible

of string theory in 4-dimensional Minkowski space-time.
