  It has recently been argued that the singularity of the Milne orbifold can be
resolved in higher spin theories. In string theory scattering amplitudes,
however, the Milne singularity gives rise to ultraviolet divergences that
signal uncontrolled backreaction. Since string theory in the low tension limit
is expected to be a higher spin theory (although precise proposals only exist
in special cases), we investigate what happens to these scattering amplitudes
in the low tension limit. We point out that the known problematic ultraviolet
divergences disappear in this limit. In addition we systematically identify all
divergences of the simplest 2-to-2 string scattering amplitude on the Milne
orbifold, and argue that the divergences that survive in the low tension limit
have sensible infrared interpretations.
