Do evaporating black holes ever lose their event horizons?
Original: Ask Ethan: Do evaporating black holes ever lose their event horizons? When black holes evaporate, their event horizons s
Astrophysicist Ethan Siegel tackles a reader question about Hawking radiation: as black holes evaporate, their event horizons shrink, raising the question of whether sufficiently small horizons could expose something other than a singularity at the core. The discussion explores what happens at the end stages of black hole evaporation and what theoretical physics predicts about these objects' final fate.
Why now: The piece addresses a longstanding puzzle in theoretical physics about the endpoint of black hole evaporation, which keeps engaging space and science audiences.

If those horizons get small enough, could they possibly reveal some object other than a singularity at their cores? bigthink.com/starts-with-... #space… · startswithabang.bsky.social@bsky.brid.gy · 2
