Query: Towards non-AdS Holography via the Long String Phenomenon   The microscopic description of AdS space obeys the holographic principle in
the sense that the number of microscopic degrees of freedom is given by the
area of the holographic boundary. We assume the same applies to the microscopic
holographic theories for non-AdS spacetimes, specifically for Minkowski, de
Sitter, and AdS below its curvature radius. By taking general lessons from
AdS/CFT we derive the cut-off energy of the holographic theories for these
non-AdS geometries. Contrary to AdS/CFT, the excitation energy decreases
towards the IR in the bulk, which is related to the negative specific heat of
black holes. We construct a conformal mapping between the non-AdS geometries
and $AdS_3\!\times\! S^{q}$ spacetimes, and relate the microscopic properties
of the holographic theories for non-AdS spaces to those of symmetric product
CFTs. We find that the mechanism responsible for the inversion of the
energy-distance relation corresponds to the long string phenomenon. This same
mechanism naturally explains the negative specific heat for non-AdS black holes
and the value of the vacuum energy in (A)dS spacetimes.
