Abstract
We will argue that the divergence in time for the asymptotic observer occurs because of specifying the position of the Horizon beyond the Planck scale. In fact, a similar divergence in time will also occur for an in-going observer in Rainbow gravity, if we again specify the position of the Horizon beyond the Planck scale. On the other hand, if we accept the occurrence of a minimum measurable length scale associated with an universal invariant maximum energy scale in Rainbow gravity, then the time taken by both the in-going and asymptotic observers will be finite.
