Black holes may avoid singularities when charge and Hawking radiation combine, theoretical physicist argues


Theoretical physicist Francesco Di Filippo proposes that the combination of electromagnetic repulsion and Hawking radiation may prevent the formation of singularities and Cauchy horizons in certain black holes. The research suggests that resolving these internal pathologies might not require a full theory of quantum gravity, though the author notes the work is currently speculative.

“Francesco Di Filippo, a researcher at the Institute for Theoretical Physics in Frankfurt, recently carried out a theoretical study that challenges the assumption that black holes must inevitability possess either a singularity or a Cauchy horizon.”
MISLEADING
While a researcher named Francesco Di Filippo exists and has written on Cauchy horizons, the evidence shows he is affiliated with Charles University in Prague, not the Institute for Theoretical Physics in Frankfurt. The claim misidentifies his institution.
