The Chaotic Dance of Black Hole Singularities: The Return of the Mixmaster Universe
This article recounts the journey of physicists exploring the chaotic phenomena near black hole singularities. In the 1960s, Misner's "Mixmaster universe" model described the chaotic changes of space and time around singularities, but was shelved due to computational limitations. Recently, with new mathematical tools and increased computational power, scientists have revisited this model, attempting to unify general relativity and quantum mechanics by studying the extreme environment of singularities to ultimately reveal the nature of spacetime. Researchers utilize Maldacena's AdS/CFT correspondence to explore chaotic behavior near singularities in simplified models, hoping to prove that previous simplifying assumptions are valid and ultimately construct a theory of quantum gravity.
