# Causal bubbles in globally hyperbolic spacetimes

@inproceedings{GarciaHeveling2022CausalBI, title={Causal bubbles in globally hyperbolic spacetimes}, author={Leonardo Garc'ia-Heveling and Elefterios Soultanis}, year={2022} }

. We give an example of a spacetime with a continuous metric which is globally hyperbolic and exhibits causal bubbling. The metric moreover splits orthogonally into a timelike and a spacelike part. We discuss our example in the context of energy conditions and the recently introduced synthetic timelike curvature-dimension (TCD) condition. In particular we observe that the TCD-condition does not, by itself, prevent causal bubbling.

Milne-like spacetimes are a class of hyperbolic FLRW spacetimes which admit continuous spacetime extensions through the big bang, τ = 0. The existence of the extension follows from writing the metric…

A main focus of this work is the introduction of synthetic curvature bounds, akin to the theory of Alexandrov and CAT(k)-spaces, based on triangle comparison, for Lorentzian manifolds with metrics of low regularity, closed cone structures, and certain approaches to quantum gravity.
