Black Holes

New Maps of the Bizarre, Chaotic Space-Time Inside Black Holes | Quanta Magazine

Physicists are exploring the chaotic nature of space-time near black hole singularities using new mathematical tools and the AdS/CFT correspondence. Recent research revisits the Mixmaster universe theory from the 1960s, suggesting that space near singularities experiences chaotic stretching and compression in multiple directions. These studies aim to reconcile general relativity with quantum mechanics and potentially reveal fundamental truths about space-time.

Gravitational Effects of a Small Primordial Black Hole Passing Through the Human Body

Research examines the gravitational effects of primordial black holes (PBH) passing through human bodies, focusing on shock wave damage and cellular dissociation. The study determines a minimum mass threshold of 1.4×10^17g for causing serious injury, concluding that PBHs pose no observable threat to humans due to their low density.
