  We show that our recent Bohr-like approach to black hole (BH) quantum physics
implies that space-time quantization could be energy-dependent. Thus, in a
certain sense, space-time can be neither discrete nor continuous. Our approach
permits also to show that the "volume quantum" of the Schwarzschild space-time
increases with increasing energy during BH evaporation and arrives to a maximum
value when the Planck scale is reached and the generalized uncertainty
principle (GUP) prevents the total BH evaporation. Remarkably, this result does
not depend on the BH original mass. The interesting consequence is that the
behavior of BH evaporation should be the same for all Schwarzschild BHs when
the Planck scale is approached.
