The world is discrete

We argue that the scale-free spectrum that is observed in the cosmic
microwave background is the result of a phase transition in the early
universe. The observed tilt of the spectrum, which has been measured
to be 0.04, is shown to be equal to the anomalous scaling dimension of
the correlation function. The phase transition replaces inflation as
the mechanism that produces this spectrum. The tilt further
indicates that there is a fundamental small length scale in nature
that we have not yet observed in any other way.
