Résumé |
Singularity theorems suggest that spacetime singularities are unavoidable in general relativity when matter
satisfies standard energy conditions. Although Hawking radiation provides a well-understood mechanism
for violating these conditions, the resulting violation is commonly regarded as too weak to remove
singularities, reinforcing the view that exotic physics or full quantum gravity is required. In this talk,we
challenge this view by analyzing a charged spherically symmetric black hole formed through gravitational
collapse and evaporating via Hawking radiation. We show that the electromagnetic repulsion and the mild
violation of energy conditions due to the presence of Hawking radiation can be sufficient to avoid the
formation of both a singularity and a Cauchy horizon. |
