Exploring Cauchy horizons: The black hole boundary where physics breaks down and causality reverses
By
Leah Crane
Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
This article explores the concept of Cauchy horizons inside certain types of black holes. It explains how at this theoretical boundary, the normal laws of physics break down, causality becomes disrupted, and the future could theoretically influence the past. The piece uses the engaging metaphor of falling into a black hole to introduce complex astrophysical concepts, discussing event horizons, singularities, and the exotic physics that may exist beyond the Cauchy horizon.
