Abstract
In this work we study a gedanken experiment constructed in order to test the cosmic censorship hypothesis and the second law of black hole thermodynamics. Matter with a negative gravitating energy is imagined added to a near extremal U(1)-charged static black hole in Einstein-Maxwell theory. The dynamics of a similar process is studied and the thermodynamical properties of the resulting black hole structure are discussed. A new mechanism which stabilizes black hole event horizons is shown to operate in such processess.
