Abstract EN
Recent results show that important singularities in General Relativity can be naturally described in terms of finite and invariant canonical geometric objects.
Consequently, one can write field equations which are equivalent to Einstein's at nonsingular points but, in addition remain well-defined and smooth at singularities.
The black hole singularities appear to be less undesirable than it was thought, especially after we remove the part of the singularity due to the coordinate system.
Black hole singularities are then compatible with global hyperbolicity and do not make the evolution equations break down, when these are expressed in terms of the appropriate variables.
The charged black holes turn out to have smooth potential and electromagnetic fields in the new atlas.
Classical charged particles can be modeled, in General Relativity, as charged black hole solutions.
Since black hole singularities are accompanied by dimensional reduction, this should affect Feynman's path integrals.
Therefore, it is expected that singularities induce dimensional reduction effects in Quantum Gravity.
These dimensional reduction effects are very similar to those postulated in some approaches to make Quantum Gravity perturbatively renormalizable.
This may provide a way to test indirectly the effects of singularities, otherwise inaccessible.
