A new study challenges the stability of black holes as described by the Kerr solution, which is based on Einstein's theory of general relativity. The research suggests that black holes may experience internal instabilities due to energy accumulation, potentially altering their structure over time. This finding implies that the Kerr solution may not fully explain black holes, prompting the need for new theoretical models to better understand their dynamics. The study is published in Physical Review Letters.

University of Southern California molecular biologist John Tower proposes a new universal law of biology called 'selectively advantageous instability,' which suggests that some level of instability is essential for life. This instability, while leading to resource loss and genetic mutations, is crucial for adaptation and complexity in biological systems, potentially explaining the process of aging.
