Recent results have shown that singularities can be avoided from the general
relativistic standpoint in Lorentzian-Euclidean black holes by means of the
transition from a Lorentzian to an Euclidean region where time loses its
physical meaning and becomes imaginary. This dynamical mechanism, dubbed
“atemporality”, prevents the emergence of black hole singularities and the
violation of conservation laws. Dans ce document, the notion of atemporality
together with a detailed discussion of its implications is presented from a
philosophical perspective. The main result consists in showing that
atemporality is naturally related to conservation laws.

Cet article explore les excursions dans le temps et leurs implications.
