摘要: In the study of weak cosmic censorship conjectures (WCCC), some research finds that the Reissner-Nordström black hole might be destroyed by a test particle with particular mass and charge under some conditions, which means that the naked singularity of the black hole could be observed. This is not allowed in WCCC. We have never observed such naked singularities which should not exist in theory, so we need to find a proper way to protect the black hole from being destroyed by such particles. In this paper, we study a Reissner-Nordström black hole that is surrounded by quintessence (RN-Q) and find that the black hole would be stable and safe because of the effective potential barrier induced by the quintessence term. This result may also show in a sense that the quintessence might have more potential value.

This is not allowed in WCCC. We have never observed such naked singularities which should not exist in theory, so we need to find a proper way to protect the black hole from being destroyed by such particles. In this paper, we study a Reissner-Nordström black hole that is surrounded by quintessence (RN-Q) and find that the black hole would be stable and safe because of the effective potential barrier induced by the quintessence term. This result may also show in a sense that the quintessence might have more potential value.
