Abstract: (arXiv)

Assume that there exists a fundamental theory of gravity which has a fundamental length scale and which is capable of explaining black hole evolution process fully in terms of fundamental microscopic degrees of freedom. The resultant evolution will clearly be unitary and will have no information loss. Carrying this assumption to its logical conclusion and, in particular, by considering the size of the region obtained by resolving the black hole singularity in such a theory, we arrive at a scenario very similar to that in Mathur's fuzz ball proposal where there is no horizon. We also comment on the consistency of such a picture with the recent results of Almheiri et al.

Note:

13 pages. Version 2: A footnote + a few minor changes added, mentioning a point which was left implicit. Version 3: A reference added. Version 4: d dependence is restored in formulas where d = 4 was assumed implicitly

black hole: singularity
sphere: fuzzy
black hole: information theory
evolution equation
